Safety rules [YCG667001-], H8040
General safety rules Use caution when operating the machine on slopes. Raised equipment, full tanks and other loads will change the center of gravity of the machine. The machine can tip or roll over when near ditches and embankments or uneven surfaces. Never permit anyone other than the operator to ride on the machine. Never operate the machine under the influence of alcohol, drugs, or while otherwise impaired. When digging or using ground engaging attachments be aware of buried cables. Contact local utilities to determine the locations of services. Pay attention to overhead power lines and hanging obstacles. High voltage lines may require significant clearance for safety. Hydraulic oil or diesel fuel leaking under pressure can penetrate the skin, causing serious injury or infection. • DO NOT use your hand to check for leaks. Use a piece of cardboard or paper. • Stop engine, remove key and relieve the pressure before connecting or disconnecting fluid lines. • Make sure all components are in good condition and tighten all connections before starting the engine or pressurizing the system. • If hydraulic fluid or diesel fuel penetrates the skin, seek medical attention immediately. • Continuous long term contact with hydraulic fluid may cause skin cancer. Avoid long term contact and wash the skin promptly with soap and water. Keep clear of moving parts. Loose clothing, jewelry, watches, long hair, and other loose or hanging items can become entangled in moving parts. Wear protective equipment when appropriate. DO NOT attempt to remove material from any part of the machine while it is being operated or components are in motion. Make sure all guards and shields are in good condition and properly installed before operating the machine. Never operate the machine with shields removed. Always close access doors or panels before operating the machine. Dirty or slippery steps, ladders, walkways, and platforms can cause falls. Make sure these surfaces remain clean and clear of debris. A person or pet within the operating area of a machine can be struck or crushed by the machine or its equipment. DO NOT allow anyone to enter the work area. Raised equipment and/or loads can fall unexpectedly and crush persons underneath. Never allow anyone to enter the area underneath raised equipment during operation. Never operate engine in enclosed spaces as harmful exhaust gases may build up. Before starting the machine, be sure that all controls are in neutral or park lock position. Start the engine only from the operator’s seat. If the safety start switch is bypassed, the engine can start with the transmission in gear. Do not connect or short across terminals on the starter solenoid. Attach jumper cables as described in the manual. Starting in gear may cause death or serious injury. Always keep windows, mirrors, all lighting, and Slow Moving Vehicle (SMV) emblem clean to provide the best possible visibility while operating the machine. Operate controls only when seated in the operator’s seat, except for those controls expressly intended for use from other locations. 47487694 17/01/2013

INTRODUCTION
Before leaving the machine: 1. Park machine on a firm level surface. 2. Put all controls in neutral or park lock position. 3. Engage park brake, use wheel chocks if required. 4. Lower all hydraulic equipment — Implements, header, etc. 5. Turn off engine and remove key. When, due to exceptional circumstances, you would decide to keep the engine running after leaving the operator’s station, then the following precautions must be followed: 1. Bring the engine to low idle speed. 2. Disengage all drive systems. 3.
WARNING Some components may continue to run down after disengaging drive systems. Make sure all drive systems are fully disengaged. Failure to comply could result in death or serious injury. W0113A
Shift the transmission into neutral. 4. Apply the parking brake.
General maintenance safety Keep area used for servicing the machine clean and dry. Clean up spilled fluids. Service machine on a firm level surface. Install guards and shields after servicing the machine. Close all access doors and install all panels after servicing the machine. Do not attempt to clean, lubricate, clear obstructions or make adjustments to the machine while it is in motion or while the engine is running. Always make sure working area is clear of tools, parts, other persons and pets before you start operating the machine. Unsupported hydraulic cylinders can lose pressure and drop the equipment causing a crushing hazard. Do not leave equipment in a raised position while parked or during service, unless securely supported. Jack or lift the machine only at jack or lift points indicated in this manual. Incorrect towing procedures can cause accidents. When towing a disabled machine follow the procedure in this manual. Use only rigid tow bars. Stop the engine, remove key and relieve pressure before disconnecting or connecting fluid lines. Stop the engine and remove key before disconnecting or connecting electrical connections. Scalding can result from incorrect removal of coolant caps. Cooling system operates under pressure. Hot coolant can spray out if a cap is removed while the system is hot. Allow system to cool before removing cap. When removing a cap turn it slowly to allow pressure to escape before completely removing the cap. Replace damaged or worn tubes, hoses, electrical wiring, etc. Engine, transmission, exhaust components, and hydraulic lines may become hot during operation. Take care when servicing such components. Allow surfaces to cool before handling or disconnecting hot components. Wear protective equipment when appropriate. When welding, follow this instructions in the manual. Always disconnect the battery before welding on the machine. Always wash your hands after handling battery components.

INTRODUCTION
Wheels and tires Make sure tires are correctly inflated. Do not exceed recommended load or pressure. Follow instructions in the manual for proper tire inflation. Tires are heavy. Handling tires without proper equipment could cause death or serious injury. Never weld on a wheel with a tire installed. Always remove tire completely from wheel prior to welding. Always have a qualified tire technician service the tires and wheels. If a tire has lost all pressure, take the tire and wheel to a tire shop or your dealer for service. Explosive separation of the tire can cause serious injury. DO NOT weld to a wheel or rim until the tire is completely removed. Inflated tires can generate a gas mixture with the air than can be ignited by high temperatures from welding procedures performed on the wheel or rim. Removing the air or loosening the tire on the rim (breaking the bead) will NOT eliminate the hazard. This condition can exist whether tires are inflated or deflated. The tire MUST be completely removed from the wheel or rim prior to welding the wheel or rim.
Driving on public roads and general transportation safety Comply with local laws and regulations. Use appropriate lighting to meet local regulations. Make sure SMV emblem is visible. Use safety chains for trailed equipment when provided with machine or equipment. Lift implements and attachments high enough above ground to prevent accidental contact with road. When transporting equipment or machine on a transport trailer, make sure it is properly secured. Be sure the SMV on the equipment or machine is covered while being transported on a trailer. Be aware of overhead structures or power lines and make sure the machine and/or attachments can pass safely under. Travel speed should be such that complete control and machine stability is maintained at all times. Slow down and signal before turning. Pull over to allow faster traffic to pass. Follow correct towing procedure for equipment with or without brakes.
Fire and explosion prevention Fuel or oil leaked or spills on hot surfaces or electrical components can cause a fire. Crop materials, trash, debris, bird nests, or flammable material can ignite on hot surfaces. Always have a fire extinguisher on or near the machine.

INTRODUCTION
Utility safety When digging or using ground-engaging equipment, be aware of buried cables and other services. Contact your local utilities or authorities, as appropriate to determine the locations of services. Make sure the machine has sufficient clearance to pass in all directions. Pay special attention to overhead power lines and hanging obstacles. High voltage lines may require significant clearance for safety. Contact local authorities or utilities to obtain safe clearance distances from high voltage power lines. Retract raised or extended components, if necessary. Remove or lower radio antennas or other accessories. Should a contact between the machine and an electric power source occur, the following precautions must be taken: • Stop the machine movement immediately. • Apply the park brake, stop the engine, and remove the key. • Check if you can safely leave the cab or your actual position without contact with electrical wires. If not, stay in your position and call for help. If you can leave your position without touching lines, jump clear of the machine to make sure you do not make contact with the ground and the machine at the same time. • Do not permit anyone to touch the machine until power has been shut off to the power lines.
Working at heights When the normal use and maintenance of the machine requires working at heights: • Correctly use installed steps, ladders, and railings. • Never use ladders, steps, or railings while the machine is moving. • Do not stand on surfaces which are not designated as steps or platforms. Do not use the machine as a lift, ladder, or platform for working at heights.
Lifting and overhead loads Never use lifting or handling equipment to lift persons. Do not used raised equipment as a work platform. Know the full area of movement of the machine and equipment and do not enter or permit anyone to enter the area of movement while the machine is in operation. Never enter or permit anyone to enter the area underneath raised equipment. Equipment and/or loads can fall unexpectedly and crush persons underneath it. Do not leave equipment in raised position while parked or during service, unless securely supported. Hydraulic cylinders must be mechanically locked or supported if they are left in a raised position for service or access. Headers or other lifting and handling equipment and its load will change the center of gravity of the machine. This can cause the machine to top on slopes or uneven ground. Load items can fall off the lifting equipment and crush the operator. Care must be taken when lifting a load. Use proper lifting equipment. Do not lift load higher than necessary. Lower loads to transport. Remember to leave appropriate clearance to the ground and other obstacles. Equipment and associated loads can block visibility and cause an accident. Do not operate with insufficient visibility.
Mounting and dismounting Mount and dismount the machine only at designated locations that have handholds, steps, or ladders. Do not jump off the machine. 47487694 17/01/2013

INTRODUCTION
Foreword - Ecology and the environment H8000
Soil, air, and water are vital factors of agriculture and life in general. When legislation does not yet rule the treatment of some of the substances required by advanced technology, sound judgment should govern the use and disposal of products of a chemical and petrochemical nature. NOTE: The following are recommendations that may be of assistance: • Become acquainted with and ensure that you understand the relative legislation applicable to your country. • Where no legislation exists, obtain information from suppliers of oils, filters, batteries, fuels, antifreeze, cleaning agents, etc., with regard to their effect on man and nature and how to safely store, use, and dispose of these substances. • Agricultural consultants will, in many cases, be able to help you as well.
Helpful hints • Avoid filling tanks using cans or inappropriate pressurized fuel delivery systems that may cause considerable spillage. • In general, avoid skin contact with all fuels, oils, acids, solvents, etc. Most of them contain substances that may be harmful to your health. • Modern oils contain additives. Do not burn contaminated fuels and or waste oils in ordinary heating systems. • Avoid spillage when draining off used engine coolant mixtures, engine, gearbox and hydraulic oils, brake fluids, etc. Do not mix drained brake fluids or fuels with lubricants. Store them safely until they can be disposed of in a proper way to comply with local legislation and available resources. • Modern coolant mixtures, i.e. antifreeze and other additives, should be replaced every two years. They should not be allowed to get into the soil, but should be collected and disposed of properly. • Do not open the air-conditioning system yourself. It contains gases that should not be released into the atmosphere. Your NEW HOLLAND AGRICULTURE dealer or air conditioning specialist has a special extractor for this purpose and will have to recharge the system properly. • Repair any leaks or defects in the engine cooling or hydraulic system immediately. • Do not increase the pressure in a pressurized circuit as this may lead to a component failure. • Protect hoses during welding as penetrating weld splatter may burn a hole or weaken them, allowing the loss of oils, coolant, etc.

Basic instructions - Shop and assembly SHIMMING For each adjustment operation, select adjusting shims and measure individually using a micrometer, then add up the recorded values. Do not rely on measuring the entire shimming set, which may be incorrect, or the rated value indicated on each shim.
ROTATING SHAFT SEALS For correct rotating shaft seal installation, proceed as follows: • before assembly, allow the seal to soak in the oil it will be sealing for at least thirty minutes. • thoroughly clean the shaft and check that the working surface on the shaft is not damaged. • position the sealing lip facing the fluid; with hydrodynamic lips, take into consideration the shaft rotation direction and position the grooves so that they will deviate the fluid towards the inner side of the seal. • coat the sealing lip with a thin layer of lubricant (use oil rather than grease) and fill the gap between the sealing lip and the dust lip on double lip seals with grease. • insert the seal in its seat and press down using a flat punch or seal installation tool. Do not tap the seal with a hammer or mallet. • whilst inserting the seal, check that it is perpendicular to the seat; once settled, make sure that it makes contact with the thrust element, if required. • to prevent damaging the seal lip on the shaft, position a protective guard during installation operations.
O-RING SEALS Lubricate the O-RING seals before inserting them in the seats, this will prevent them from overturning and twisting, which would jeopardise sealing efficiency.
SEALING COMPOUNDS Apply one of the following sealing compounds on the mating surfaces when specified: SILMATE® RTV1473, or LOCTITE® RTV 598 or LOCTITE® INSTANT GASKET 587 BLUE. Before applying the sealing compound, prepare the surfaces as directed on product container or as follows: • remove any incrustations using a metal brush. • thoroughly de-grease the surfaces using a locally approved cleaning agent such as safety solvent or brake parts cleaner.
SPARE PARTS Only use "CNH Original Parts" or " NEW HOLLAND AGRICULTURE Parts". Only genuine spare parts guarantee the same quality, duration and safety as original parts, as they are the same parts that are assembled during standard production. Only "CNH Original Parts" or " NEW HOLLAND AGRICULTURE Parts" can offer this guarantee. When ordering spare parts, always provide the following information: • machine model (commercial name) and serial number. • part number of the ordered part, which can be found in the "Microfiches" or the "Service Parts Catalogue", used for order processing.

PROTECTING THE ELECTRONIC/ ELECTRICAL SYSTEMS DURING CHARGING OR WELDING WARNING Battery acid causes burns. Batteries contain sulfuric acid. Avoid contact with skin, eyes or clothing. Antidote (external): Flush with water. Antidote (eyes): flush with water for 15 minutes and seek medical attention immediately. Antidote (internal): Drink large quantities of water or milk. Do not induce vomiting. Seek medical attention immediately. Failure to comply could result in death or serious injury. W0111A
To avoid damage to the electronic/electrical systems, always observe the following: 1. Never make or break any of the charging circuit connections, including the battery connections, when the engine is running. 2. Never short any of the charging components to ground. 3. Always disconnect the ground cable from the battery before arc welding on the windrower or on any header attached to the windrower. • position the welder ground clamp as close to the welding area as possible. • if welding in close proximity to a computer module, then the module should be removed from the windrower. • never allow welding cables to lay on, near or across any electrical wiring or electronic component while welding is in progress. 4. Always disconnect the negative cable from the battery when charging the battery in the windrower with a battery charger. NOTICE: If welding must be performed on the unit, either the windrower or the header (if it is attached), the battery ground cable must be disconnected from the windrower battery. The electronic monitoring system and charging system will be damaged if this is not done. Remove the battery ground cable. Reconnect the cable when welding is completed.

INTRODUCTION
Basic instructions - Hydraulic contamination [YCG667001-]
Contamination in the hydraulic system is a major cause of the malfunction of hydraulic components. Contamination is any foreign material in the hydraulic oil. Contamination can enter the hydraulic system in several ways: • When you drain the oil or disconnect any line • When you disassemble a component • From normal wear of the hydraulic components • From damaged seals or worn seals • From a damaged component in the hydraulic system All hydraulic systems operate with some contamination. The design of the components in this hydraulic system permits efficient operation with a small amount of contamination. An increase in this amount of contamination can cause problems in the hydraulic system. The following list includes some of these problems: • Cylinder rod seals that leak • Control valve spools that do not return to neutral • Movement of control valve spools is difficult • Hydraulic oil that becomes too hot • Pump gears, housing, and other parts that wear rapidly • Relief valves or check valves held open by dirt • Quick failure of components that have been repaired • Slow cycle times are slow. The machine does not have enough power. If your machine has any of these problems, check the hydraulic oil for contamination. There are two types of contamination: microscopic and visible. Microscopic contamination occurs when very fine particles of foreign material are suspended in the hydraulic oil. These particles are too small to see or feel. Microscopic contamination can be found by identification of the following problems or by testing in a laboratory. Examples of problems caused by microscopic contamination: • Cylinder rod seals that leak • Control valve spools that do not return to neutral • The hydraulic system has a high operating temperature Visible contamination is foreign material that can be found by sight, touch, or odor. Visible contamination can cause a sudden failure of components. Examples of problems caused by visible contamination: • Particles of metal or dirt in the oil • Air in the oil • Dark or thick oil • Oil with an odor of burned oil • Water in the oil If you find contamination, use a portable filter to clean the hydraulic system.

INTRODUCTION
General specification - Biodiesel Fuels Fatty Acid Methyl Ester Biodiesel (Biodiesel Fuel) consists of a family of fuels derived from vegetable oils treated with methyl esters. NOTICE: Biodiesel Fuel blends are approved for your engine only if they comply with EN14214 Specification Standards or ASTM D6751. NOTICE: It is imperative that you check which blend is approved for your engine with your NEW HOLLAND AGRICULTURE dealer. Be aware that the use of Biodiesel Fuel that does not comply with the Standards mentioned above could lead to severe damage to the engine and fuel system of your machine. The use of fuels that are not approved may void NEW HOLLAND AGRICULTURE Warranty coverage.
Biodiesel Fuel Usage Conditions NOTICE: The Biodiesel Fuel must meet the fuel Specification mentioned above. Biodiesel Fuel must be purchased from a trusted supplier that understands the product and maintains good fuel quality. Biodiesel Fuel must be pre-blended by the supplier. Mixing Biodiesel Fuels on-site can result incorrect mixture that can lead to problems with both engine and fuel system. Engine performance is affected by the use of Biodiesel Fuel. There may be up to 12 % reduction in power or torque depending on the blend used. NOTICE: DO NOT modify the engine and/or injection pump settings to recover the reduced performance. The reduced power must be accepted if using any Biodiesel Fuel blend. Some modification may be required to allow your engine to run Biodiesel Fuel. Consult you dealer for complete information on these modifications. Biodiesel Fuel has a higher cloud point than Diesel Fuel. NOTICE: The use of high Biodiesel Fuel blends are not recommended in cold weather conditions. With Biodiesel Fuels, it may be necessary to change the engine oil, engine oil filter and fuel filter elements more frequently than with Diesel Fuels. Biodiesel Fuel can remove rust and particles from the inside of on-site fuel storage tanks that would normally adhere to the sides of the tank. Like particle deposits that commonly occur with Diesel Fuel, these particles can become trapped by the machine fuel filters, causing blockage and shortening filter life. In cold weather, this is more likely to happen. Consult your NEW HOLLAND AGRICULTURE dealer for information on cold weather operation and proper maintenance intervals when using any Biodiesel Fuel blend. When handling Biodiesel Fuel, care must be taken not to allow water into the fuel supply. Biodiesel Fuel will actually attract moisture from the atmosphere. Fuel tanks must be kept as full as possible to limit the amount of air and water vapors in them. It may be necessary to drain the fuel filter water tap more frequently. Potential oxidation and stability could be a problem with the fuel stored in the machine. NOTICE: Machines must not be stored for more than three months with Biodiesel Fuel blends in the fuel system. If long storage periods are necessary, the engine must run on Diesel Fuel for 20 hours to flush the Biodiesel Fuel out of the engine fuel system prior to storage. NOTICE: Biodiesel Fuel must not be stored in on-site storage tanks for more than three months. Any spillage of Biodiesel Fuel must be cleaned up immediately before it can cause damage to the environment and the paint finish of the machine. Before using Biodiesel Fuel blends you should consult with your dealer to receive full information about the approved blend for your machine and any detailed conditions of its usage. NOTICE: Be aware that not fulfilling the requirements and conditions of Biodiesel Fuel usage will void your machine’s NEW HOLLAND AGRICULTURE Warranty coverage.

The Pressure Relief Valve is located at rear end of the fuel rail. This pressure relief valve protects the fuel system components from excessive pressure if: •
The Rail Pressure Sensor fails to signal the correct pressure to the ECU (Engine Control Unit).
•
The High Pressure Flow Regulator, located at the pump, allows excessive pressure in the high pressure system. Check the ECU for:
•
Fault codes related to over pressurization of the common rail, refer to: High Pressure Flow Regulator.
Disconnect the pressure relief valve return line and cap the line with 380100060 cap. Install 380100057 gauge and hose assembly on the relief valve to direct any leakage to container 380100062 if the relief valve is leaking.
NOTE: Under normal circumstances fuel should not come out of the relief valve. 10.

The High Pressure Flow Regulator is an electrical control located at the inlet of the high pressure pump. It regulates the amount of fuel supplied to the high pressure system based on control signals received from the ECU (by modulating the pulses sent to the internal solenoid). This is used to control the pressure within the fuel rail. •
The high pressure flow regulator is normally open.
•
The high pressure pump is in maximum delivery mode if no control signal is sent by the ECU.
If the high pressure flow regulator has an open circuit (the flow regulator is disconnected, the harness is broken, etc.) or a short circuit (resistance value is much lower than 3.2 Ω): •
The pump will be in maximum delivery mode and pressure in the rail will exceed 1700 bar (24650 psi) for a very short amount of time.
•
The High pressure relief valve will open.
•
The ECU sense the over pressure condition and store fault codes in the ECU memory.
•
The engine will derate.
13.
Check the resistance (on the ECU connector pins). The resistance specification is approximately 3.2 Ω.
14.
When in parameter mode on the Electronic Service Tool, the duty cycle reading indicates the position of the regulator.
NOTICE: When all of the system components have been checked, inspect for the following symptoms: The duty cycle tends to fluctuate irregularly and the engine idle speed is irregular. • The engine stalls when idling and no fault is stored in the ECU. • Starting is difficult (takes longer than 4 seconds). Replace the high pressure flow regulator.

Engine load and rpm are controlled by the fuel injectors. The load requested by the operator is controlled by the throttle position and converted into a fuel quantity by the ECU. The ECU controls the amount and timing of the fuel injection (using current fuel rail pressure as a factor). Fuel injector mechanical problems: •
If the engine is difficult to start (excessive cranking time and no fault codes present):
•
Warm engine to 50 °C (122 °F) minimum. Check for excessive fuel return of the cylinder head injectors (with the engine running at low idle (no load - A/C etc.). Complete (A) and/or (B) as required.
NOTE: Return leakage can be checked at various locations (at the filter base or the cylinder head depending on ease of the connection. If excessive leakage is found, additional testing will be required to determine the exact location(s) of the leakage. Each fuel injector connector and the pressure relief valve could be a source of excessive return flow. More than one component could be responsible for excessive return.

If leakage from the cylinder head port exceeds 80 ml (2.7 US fl oz) per minute with the engine running at low idle, check the leakage within each injector. •
Maintain engine temperature, 50 °C (122 °F) minimum. To locate a damaged injector, cap ( 380100061) each fuel rail outlet location; one at a time. Recheck the total leakage. When the return leakage value drops significantly with a fuel rail outlet capped, a leaking injector has been identified. Replace the damaged injector. Retest total leakage to ensure additional injectors are not leaking excessively.
•
Inspect the injector connector between each fuel injector and the associated fuel rail line. The torque specification is for the injector connector is 45 - 55 Nm (33 - 41 lb ft). Check the fuel injector end of the connector to make sure is not deformed. If the injector end of the connector is deformed, replace the injector connector.
•
If the injector supply tube is not the cause of the leakage, the injector may have internal leakage and require replacement. Injectors could leak excessively at operating temperature and perform correctly cold. Test kits 380040185 and 380040188 can be used to bench test injectors.
NOTE: Injectors and injector connectors are replaced as pairs.

The air intake system brings screened air through a tube from the rotary screen cleaner housing at the rear of the machine to the air cleaner, then through another tube, to the turbocharger, where it is pressurized. Then passes to the aftercooler to extract heat and then back to the intake manifold. While passing through the air cleaner, large particles are removed by use of exhaust-driven aspiration through the evacuator hose, connected at the bottom of the end cap, and they are expelled through the exhaust stack.

Self-Propelled Windrowers come equipped with an Auburn Model 8, double reduction final drive hubs. The hydraulic motor shaft, (1), rotates as flow is applied from the pumps. A coupling, (2), has internal splines and makes the connection from the motor shaft to the hub shaft, (3). The primary sun gear, (4), is splined onto the end of the hub shaft. The model 8 drive hub will have eight lug nuts.

Movement of the gears will cause the primary carrier, (1), to rotate. A splined bushing, (2), fits into the primary carrier casing and is free to rotate at a different speed as the hub shaft. As the bushing, (2), is turning by the primary carrier, the planet gears, (3), of the secondary carrier will rotate. Since the casing of the secondary carrier is held in place by a stationary spline shaft at, (4), the rotating planet gears of the secondary carrier will turn the ring gear, (5).

Hydrostatic drive - Transmission and steering hydrostatic control
Hydrostatic drive system valves Shuttle spool valve - Dynamic description - SOLENOID VALVE (2-speed Drive Motor Only) Low-Range Operation The solenoid valve in the two-speed manifold remains switched off in the low range. The two-speed lines from motors connect to the return, and oil can drain out of them to the reservoir.
High-Range Operation In high range, the two-speed switch supplies power to the coil of the two-speed valve. The valve shifts and supplies charge pressure to the shuttle on the motor. The shuttle moves the motor swash plate to the lower displacement setting. The motor then turns faster at any given pump flow.

Hydrostatic drive - Transmission and steering hydrostatic control
Hydrostatic drive system valves Shuttle spool valve - Dynamic description Cooling Circuit The continuous removal of oil from the low loop side of the hydrostat via the shuttle valves on each motor provides a cooling circuit. The shuttle valves drain off 5.67 7.57 l/min (1.5 - 2.0 US gpm) from each motor under full load. The charge pump replenishes the oil removed by the shuttle operation, as well as any lost to internal leakage in the motor. NOTE: When diagnosing internal leakage in the motors, case drain flow will include the 5.67 - 7.57 l/min (1.5 - 2.0 US gpm) from the shuttle valve operation.

(F) RETAINING RING (G) PUMP HIGH PRESSURE PORT (H) RELIEF VALVE SEAT (I) CHECK VALVE SEAT (J) CHARGE PRESSURE PORT
HIGH-PRESSURE RELIEF VALVES There are two high-pressure relief valves for each pump, one each for forward and reverse. The relief valves limit the maximum pressure in the hydrostatic circuit to 38335 kPa (5560 psi) and act as check valves, allowing charge pressure to enter the low side. The high-pressure relief valves all are identical and are a nonadjustable cartridge-type set at the factory.
CHECK VALVES The check valves are part of the high-pressure relief valves. Since all of the main hydraulic lines can be under high pressure, four charge check valves direct the charge supply into the low-pressure line. Any charge flow (pressurized hydraulic oil) not used for the closed circuit, discharges via a direct operating charge relief valve, through the pump and motor housings, and back to the system reservoir.

Hydrostatic drive - Transmission and steering hydrostatic control
Hydrostatic drive system valves Relief valve - Dynamic description Operation The high-pressure relief valve is a cartridge-type valve using a poppet and plunger, (1), to relieve the oil in the high-loop side when the pressure exceeds 38335 kPa (5560 psi). The relief valve spring, (2), keeps the poppet plunger against its seat. When pressure in the high loop side of the hydrostat exceeds the cartridge setting, it forces open the poppet plunger, releasing the excess pressure. The check valve spring, (3), keeps the check valve against its seat.When the pump reverses oil flow, the charge pressure pushes the check valve off its seat and oil is supplied to the pump. 20105273NN

Hydrostatic drive system valves Relief valve - Check High-Pressure Valve Check When a problem occurs in one direction, switch the relief valves to see whether the problem moves with the valves to the other direction. If so, then one valve is malfunctioning or the check/relief valve cartridge does not have the proper setting. NOTICE: The relief valves are factory set and should not be tampered with except to replace entire cartridge. Disassembly may change the setting and cause erratic unit operation or permanent failure. Install a high-pressure gauge in the system pressure gauge ports (or tee it into the high- pressure lines) to check the setting of the system pressure relief valves. A three-digit code stamped on the cartridge indicates the pressure setting of the valve (in bar). To remove the cartridge, gently pull the cartridge straight out of the plug bore.

Hydrostatic drive - Transmission and steering hydrostatic control
Hydrostatic drive system valves Relief valve - Pressure test CHARGE PUMP RELIEF VALVE If charge pressure is low, inspect the charge relief valve. Before removing the relief valve plug, (1), the reservoir must be drained or the inlet blocked to prevent oil from leaking through the passage on the back side of the relief valve. This passage runs through the pump case to the reservoir. Inspect the poppet for foreign material, which may hold the poppet open, and for scoring or wear on both the poppet and seat area. To adjust the charge pressure, change the shim thickness behind the spring. Shim thicknesses are 0.25 mm (0.010 in), 0.51 mm (0.020 in) mm and 1.27 mm (0.050 in) and are serviced in the charge relief valve kit. The charge relief valve is factory set to 1999 kPa (290 psi). Refer to “Charge Pressure System Test� in this section of the manual for the setting procedure.

The proper high pressure relief setting is 383.4 bar (5560 psi). If the relief pressure is above or below the specified value, remove the corresponding relief valve and check for damage or debris. Replace if necessary. NOTE: The high pressure relief valves are a one-piece valve and can not be adjusted.
Case Pressure Test (Pump) Case pressure readings can help locate restrictions in the return lines, oil cooler and return filter. The case pressures in the hydrostatic pump or motor should not exceed 5.2 bar (75 psi) cold or 2.4 bar (35 psi) continuous. Check the pump case pressure at port, (1), on the pump body. With the system warm, the case pressure should be very minimal due to the suction port location of the header drive pump.

Add a tee into the charge pump inlet line, (1), or drill and tap the elbow, (2), to add a port for the vacuum gauge.
NOTICE: Keep metal particles or other debris out of the charge pump inlet. 3.
Refill the reservoir to the correct level before starting the engine.
4.
Run the engine at full throttle while performing the suction test.
Normal vacuum is 0.8 bar abs (5" Hg). If the vacuum exceeds 0.8 bar abs (5" Hg) with the oil warm, remove the suction screen and hose for inspection.
Case Flow Test The case drain on the pump cannot accurately be checked. To check the motor case drain: 1.
Install an in-line flowmeter into the return line between the port in the motor and the fitting on the return line, (1). Normal case drain and relief valve pressure at full throttle is 7.6 - 9.5 l/min (2.0 - 2.5 US gpm).
2.
If the case flow/drain exceeds 15.2 l/min (4 US gpm), inspect the motor further for internal damage.

Hydrostatic transmission - Dynamic description Troubleshooting The hydrostatic transmission troubleshooting procedure is a guideline to properly diagnose hydrostatic transmission faults. Finding the cause for a malfunctioning hydrostat is best accomplished with proper test equipment and a thorough understanding of the complete system. For a description of the system and its function, refer to “Description of Operation.� The hydrostatic transmission is designed for long, troublefree life if the recommended maintenance procedures are followed. When diagnosing a problem, examine the most likely causes first. The main symptoms of trouble in a hydrostatic system are excessively high system temperatures and noise levels. These symptoms usually indicate a defective hydrostatic component. Overall performance also is important. If the machine becomes slower, has less power or is less responsive, check the system pressure and flow.

Hydrostatic drive - Hydrostatic transmission
Hydrostatic transmission - Dynamic description Excessive Noise Investigate any excessive or unusual noise immediately. Hydrostatic system noise generally indicates cavitation caused by a restricted inlet, excessive fluid aeration or worn internal parts. Air in the system sometimes causes oil in the reservoir to have a milky appearance. A leak at the intake (suction) side will cause aeration of the fluid. Measuring the charge pump inlet vacuum will help locate restrictions in the inlet lines, filter, etc. Do not overlook the possibility of the inlet hose collapsing internally, restricting flow to the charge pump. A low-pressure condition at the inlet/charge port of the hydrostatic piston pump causes cavitation. A worn or failed charge pump is the primary cause of cavitation in the closed loop of the hydrostatic system. If the charge pump relief valve or check valve on the main system relief malfunctions, the hydrostatic pump will cavitate, causing the machine to slow down or operate erratically. Refer to “Pressure Testing� for proper diagnosis of the charge system.

Hydrostatic drive - Hydrostatic transmission
Hydrostatic transmission - Dynamic description Overheating transmissions Overheating the hydrostatic system will cause the oil to deteriorate, diminishing its ability to lubricate and resulting in internal wear and damage. When the hydrostat becomes worn, the internal leakage increases, creating excessive heat from the oil passing through the leak passages. This will slow the machine’s forward speed. If the machine loses speed after operating for awhile, check the temperature of the oil by dipping a standard thermometer in the reservoir. The temperature should not exceed 93.3 °C (200 °F). Because the hydrostatic and hydraulic systems share a common reservoir, it is important to maintain the correct oil level in the tank. Refer to “Pressure Testing” in this section for the procedure to check case drain.
Loss of Propulsion There are several reasons for a loss of propulsion by the hydrostat. The most common is a defective high-pressure relief valve that fails to open and allows oil in the high side of the loop to return to the reservoir. A loss of propulsion also can result from excessive internal leakage in the pump or motor. When inadequate charge pressure or flow cavitates the hydrostatic pump, it also reduces propulsion drastically. If the machine slows down or will not move in either direction, the high-pressure oil may be flowing back to the reservoir via internal slippage or external leakage. Check the hydrostatic linkage for proper operation before condemning the hydrostat. Refer to “Pressure Testing” in this section for the proper procedure to check the relief valves.

Hydrostatic transmission - Dynamic description EXPLANATION OF TERMS USED IN FAILURE ANALYSIS These terms and their explanations will help describe the results of testing.
Lack of Lubrication This describes failures in which the hydraulic fluid film between the surfaces of the moving parts was lost while the machine was operating. A fluid film is necessary to lubricate all the moving parts. If the lubricating film is lost, the components will have metal-to-metal contact, which eventually causes smearing or galling of the mating surfaces. The degree of smearing or galling will vary depending upon how long the unit has run without proper lubrication, as well as the severity of the problem that destroyed the lubricating film in the first place. The following are conditions that can cause a loss of lubrication and the failure associated with it:
Operating at Excessive Temperature Levels The viscosity of fluids decreases as the temperature increases. If the transmission operates at excessively high temperatures, the lubricating film may be inadequate, causing smearing on the running surface. Certain hydraulic fluids have characteristics not compatible with the application. If the fluid does not have adequate lubrication and load-carrying specifications, damage to the running surface will occur.
Cavitation If the fluid contains excessive amounts of air or foam, the air replaces the fluid in the lubricating films and causes excessive wear and damage to the running surfaces.
Overspeeding of the Unit When a pump or motor is forced to run too fast, certain components can separate and cause high unit loading on the bearing plate and slippers. The first symptom of this is a rolling on the outer foot of the bearing plate and the outer edge of the slipper face. If the unit repeatedly runs too fast, lubrication of the rotating surfaces is lost and smearing of the valve and bearing plates results.

Hydrostatic drive - Hydrostatic transmission
Hydrostatic transmission - Dynamic description PARTS WORN OR SCORED FROM CONTAMINATION Abrasive Contaminants Too many abrasive contaminants in the running surfaces will destroy the lubricating film and result in excessive wear and damage to the running surfaces. Particles of abrasive material such as dirt or metal shavings cause particle contamination when they pass through the units. This wears grooves in the bearing materials. The damage from abrasives occurs during the overall operation of the transmission and hydraulic system. The particles that cause the damage typically pass out of the pump or motor and into the reservoir prior to the repair; thus, it can be difficult to tell what kind of abrasive contamination occurred. You may only be able to inspect the components and assess the damage caused by the abrasive particles. Abrasive particles can enter the hydrostatic pumps and motors only after passing through the filter in the inlet line. To prevent this type of failure, always clean all the lines prior to installation. Make sure to prevent abrasive material from entering the system during installation.
Plates Scored from Water in Oil (Non-Particle Contaminants) Water or other fluid contaminants in the hydraulic oil can cause failure of the components. Water and other contaminants react with additives in the hydraulic oil, causing a chemical change in the oil. The oil then reacts with the brass in the system, causing etching of the finely finished surfaces. The etching strips these surfaces, allowing oil to leak under pressure. Eventually the unit will stop working altogether.

Hydrostatic transmission - Dynamic description Minor Repairs This section covers minor repairs that can be done without voiding the warranty on the hydrostatic transmissions. Minor repairs include: 1. Shaft seals in the pumps and motors 2. Charge pump replacement 3. O ring seal between the center sections 4. O ring seal between the front pump and adapter plate 5. O ring seal between the adapter plate and header lift pump 6. Trunnion seals on the control shafts 7. High-pressure relief valve and check valve 8. Charge relief valves in the pump and motor 9. Shuttle valve inspection in the motor Items 1 through 5 will require the pump to be removed or separated from the machine for repairs. Items 6 through 9 do not require complete removal of the pump and motor. Any major repair to the hydrostatic transmission should be performed by an authorized Sauer-Danfoss repair station (see the list at the end of this section). Work done by persons not authorized by Sauer-Danfoss will void any remaining warranty on the transmission. Cleanliness is extremely important to ensure satisfactory hydrostatic system life on either new or repaired units. Clean the parts in a clean solvent wash and dry them thoroughly. Air drying is usually adequate. As with any precision equipment, keep all parts free of foreign materials and chemicals. Protect all exposed sealing surfaces and open cavities from damage and foreign material. Replace all gaskets and O ring seals when making a repair. Lightly lubricate all O ring seals with clean petroleum jelly prior to assembly. Clean all gasket sealing surfaces prior to installing new gaskets. NOTE: Some of the illustrations in this section show a completely disassembled component; however, minor repairs do not involve complete disassembly of a component.

Theory of Operation The SP Windrower ground drive controls both the steering and the average speed of the vehicle. Rotation of the control shaft steers the vehicle and translation of the shaft controls the average speed of the vehicle. The Steering is controlled mechanically and the average speed of the vehicle is controlled using an electro-hydraulic system. The following figure shows a schematic of the system hardware.

The electro-hydraulic system is composed of the following components: 1. The multi-function handle (MFH) Assembly 2. An electronic control module (UCM A-001) 3. An electro-hydraulic valve 4. A spring centered hydraulic cylinder 5. A rotary position sensor (Propulsion Cylinder Position Sensor B-061 (A & B) The objective of the electro-hydraulic control system is to control the position of the hydraulic cylinder using the MFH handle position as a reference. The MFH handle assembly has two sensors built into it: 1. A rotary position sensor (MFH Position Sensor B-054) 47487694-29.202 17/01/2013
29.2 [29.202] / 20
Hydrostatic drive - Hydrostatic transmission
2. A neutral switch The angular position of the MFH is measured by the MFH Position Sensor B-054, which is located at the pivot point of the MFH handle. The rotary position sensor converts an angular position into an electrical voltage. As the angle changes the voltage changes. This voltage is measured by the control module (UCM A-001). The control module converts the voltage into a cylinder position (this is a numeric value inside the control module). This calculated cylinder position is called the cylinder position set point. The operator therefore defines the cylinder position set point by positioning the MFH handle. A rotary position sensor (Propulsion Cylinder Position Sensor B-061 (A & B) is a sensor used to measure the position of the hydraulic cylinder. Similar to the MFH Position Sensor B-054, this position sensor converts the cylinder position to an electrical voltage. The linear motion of the cylinder is converted into an angular motion using a linkage. The Propulsion Cylinder Position Sensor B-061 (A & B) measures this angular motion. The control module converts the voltage into a cylinder position. This is called the measured cylinder position. The control module compares the cylinder position set point and the measured cylinder position and calculates the cylinder position error (cylinder position set point minus cylinder position measured). The cylinder position error informs the controller what direction and how far to move the cylinder. The controller then calculates the electrical current to send to the electro-hydraulic valve. Basically the electro-hydraulic valve converts electrical current into oil flow. The oil flows in and out of the cylinder moving it. High pressure oil is supplied by the auxiliary hydraulic supply and waste oil (low pressure) is sent to the hydraulic reservoir. The controller determines and sends the current required to control oil flow to position the cylinder.

Hydrostatic transmission - Pressure test Performing several pressure and flow tests on the hydrostatic system will help pinpoint the problem areas, reducing diagnostic time and unnecessary repairs. To get accurate pressure readings, the system must be at operating temperature and rated engine speed. The interior of all test equipment must be exceptionally clean before being used on the hydrostatic system. Purge the test equipment of all oil and foreign matter to avoid contaminating the hydrostatic system.
DANGER Unexpected movement! Make sure parking brake is applied. Secure machine with wheel chocks. Failure to comply will result in death or serious injury. D0013A
Before replacing the complete hydrostatic transmission assembly, perform the following pressure tests. 1.

Charge Pressure There are three relief valves that regulate the charge pressure produced by the tandem pump assembly. One relief valve is located in the pump assembly and the other two valves are located in the wheel motors. When the hydrostatic systems is in neutral, the shuttle valves of the hydrostatic motors remain centered and block the oil from reaching the motor relief valves. Only the relief valve located in the pump assembly opens to relieve the excess oil flow from the charge pump. When the hydrostatic system is stroked, the pressure differential between the high-pressure and low-pressure sides of the wheel motors shifts the shuttle valves to allow oil flow through the motor relief valves. The relief valves on the motors must be set lower than the pump relief valve. If the relief valves are set at pressures too close to each other, the hydrostatic system will overheat or create an excessive whining noise.

To check the charge pressure relief valve, (1), install a 3447 kPa (500 psi) pressure gage into the charge pressure test port, (2).
NOTICE: Perform this test with the hydraulic oil at approximately 100 - 180 °. Record the pressure reading when the MFH is in neutral, and the engine is at 1300 RPM. This value should be 1931 - 2068 kPa (280 - 300 psi). NOTICE: The hydraulic linkage must be adjusted to true neutral to obtain a measurement of the actual pump relief valve setting. If any amount of oil flows to the wheel motors to create a pressure differential between the high-pressure and low-pressure sides of the wheel motor, the shuttle valves will shift and divert flow to the wheel relief valves rather than the pump relief valve. There are two possible causes for not achieving the proper pressure. •
Lack of oil flow, pump inefficiency
•
Improperly set or functioning relief valve

To check/adjust the pump charge pressure relief valve, (1), remove the relief valve from the pump. NOTE: Block the pump inlet or drain the reservoir before removing the relief valve to prevent oil leakage. Before any adjustment, inspect the relief valve. Look at the poppet for foreign material that could be holding the poppet open. Also check for scoring or excessive wear on the poppet and seating surfaces.
To adjust the pumps charge pressure relief valve setting, change the shim thickness, (1), behind the spring, (2). •
To increase the relief valve charge pressure, increase the thickness of the shim stack.
To decrease the relief valve charge pressure, decrease the thickness of the shim stack. Shim thicknesses are 0.25 mm (0.010 in), 0.51 mm (0.020 in), and 1.27 mm (0.050 in) and are serviced in the charge pressure relief valve kit. •

Hydrostatic drive - Pump and motor components
Pump - Dynamic description The hydrostatic transmission consists of two variable-displacement pumps, (1), driven in tandem by the engine through a transfer case at 1.5 (ratio 39:26) times engine speed, at a rated engine speed of 2300 RPM. The pumps are axial piston pumps with variable output up to . 55 l/min (41 gpm). Changing the angle of the pump swash plate reverses the direction of output flow. The auxiliary gear pump, (2), mounts to the front of the hydrostatic pump for the header lift system. The two axial pumps are mounted back-to-back and are connected by a drive coupler in the center section. The front pump drives the left-hand side of the unit, and the rear pump drives the right side. The center section, (3), between the hydrostatic pumps acts as a manifold and contains the following: • High-pressure relief valves and check valves • Charge pump • Charge pressure relief valve • Test ports for high pressure and charge pressure checks

Hydrostatic drive - Pump and motor components
Pump - Dynamic description The charge pump is a gerotor-type pump housed in the center section. It maintains positive pressure in the main circuit, compensates for internal leakage, and provides flow for cooling the hydrostatic system. The charge pump supplies pressure for the extension of the tilt and float cylinders. Charge pressure is supplied to the two-speed valve for the wheel motors parking brake release and MFH servo assist cylinder. The charge pump flow is 58.6 l/min (15.5 US gpm) at full engine RPM, regulated by the charge relief valve.
CHARGE RELIEF VALVE (PUMP) The charge pump relief valve is in the top of the rear center section and limits the charge pressure to 1999 kPa (290 psi). The valve is a simple plunger-type valve and is shim adjustable. Oil going over the relief valve flows through the pump case to the reservoir.

Hydrostatic drive - Pump and motor components
Pump - Dynamic description LINKAGE A threaded shaft connected to the swash plate arms (pintle arms) controls the oil flow from each of the transmission pumps. When the operator moves the MFH, this shaft pulls or pushes the swash plates, moving the machine forward or backward. The threaded shaft also turns with the steering wheel. The threads are right and left-handed, allowing the pintle arms to come together or spread apart as the shaft turns. This changes the oil flow of one pump in relationship to the other pump causing one wheel to turn faster or slower than the other.
Operation WARNING Stay clear! The steering tires will move automatically during this procedure. ALWAYS make sure the work area is clear of bystanders and domestic animals before starting this procedure. Know the full area of movement of the machine. Do not permit anyone to enter the area of movement during this procedure. Failure to comply could result in death or serious injury. W0066A
NOTICE: The steering wheel must be centered to keep the windrower from turning, even when the MFH is in neutral. When moving forward, the windrower turns the same direction as the steering wheel. When moving in reverse, the windrower turns the opposite direction as the steering wheel. Always engage the parking brake, center the steering wheel and shut the engine off before dismounting the windrower.

Hydrostatic drive - Pump and motor components
Motor - Dynamic description [YCG667001-]
Two individual hydrostatic motors drive the wheels. Each motor mounts on the drop housing and drives the wheel using a planetary hub. The H8040 uses a two-speed motor. Each motor has a relief valve to bleed off hot oil from the low-pressure side of the closed loop between the pump and motor. A shuttle valve between the highand low-pressure parts makes sure the relief valve receives oil from the low-pressure side. (High- and low-pressure sides switch for forward and reverse.) Cool oil is drawn into the hydrostatic pump to make up for this lost oil. This feature maintains acceptable operating temperatures when the machine is at full capacity. The relief valve is set at 1524 - 220 kPa (221 - 32 psi) and is shim adjustable.
Variable Displacement Motor The motors used on the H8040 units are variable-displacement with two speeds. The displacement varies from 34 - 46 cmÂł (2.1 - 2.8 inÂł) per revolution, increasing road speed to 25.7 km/h (16 mph). A two-speed switch uses hydraulics to change the swash plate angle to high speed (low displacement). In the low position, the switch allows a spring to return the swash plate angle to low (high displacement). A two-speed electro hydraulic valve directs charge pressure to the cylinders, changing the swash plate angle and increasing or decreasing the speed of the machine.

H8040 Operating Principles The two-speed motors on the H8040 units are controlled by an electro hydraulic valve, (1), incorporated into the H8040 control manifold. The two-speed valve is a two position three way cartridge. The valve is connected to tank and charge pressure. Charge pressure is applied when valve is energized.

Front View of Manifold Block 2 SP = 2 Speed Ground Drive Connection
RESERVOIR The hydraulic reservoir sits on the right-hand side behind the cab, and supplies oil to the charge pump, header lift pump and header drive pump. Prior to returning to the reservoir, the oil passes through two 10 micron filters. The hydraulic reservoir capacity is 52.4 l (13.8 US gal). To prevent cavitation or aeration (bubbles) in the system, maintain the proper oil level in the reservoir. Use NEW HOLLAND AMBRA MULTI G 134™ HYDRAULIC TRANSMISSION OIL hydraulic oil to fill the hydraulic reservoir.
OIL FLOW Neutral When the hydrostatic system is in neutral, there is no flow from the pumps to the motors. Charge pump flow is minimal to the closed loop circuit and is forced over the charge relief valve to the pump case. Pump case drainage flows back to the reservoir.
47487694-29.218 17/01/2013
29.3 [29.218] / 17
Hydrostatic drive - Pump and motor components
Forward/Reverse When the operator moves the control lever from neutral to forward, the pump pushes oil through the motors. Immediately, one side of the closed loop becomes the highpressure side supplying oil to the drive motor, while the opposite side becomes the return side, sending oil from the motor back to the pump. The pressure on the high side of the closed loop is dependent on the load and resistance on the machine. Highpressure relief valves in the center section of the tandem pump limit the maximum pressure. When the relief valve opens, oil flows into the charge pressure side of the low loop and then into the pump inlet. The charge pressure relief valve keeps the return side of the closed loop at charge pressure. The high-pressure relief valve on the low loop side acts as a check valve, allowing charge pressure to enter the low side. The charge flow replenishes the oil lost by the pump, motor, and shuttle valve with cool oil. The high pressure at the motor forces the shuttle valve closed on the high loop side and open on the low loop side.Oil from the low loop side flows through the shuttle valve and the motor charge relief valve and into the motor case. The motor relief valve pressure is slightly lower than that of the charge pressure relief valve in the pump. This maintains a positive charge in the low loop. Oil from the motor case drain is filtered before returning to the reservoir. When the operator moves the control lever from neutral to reverse, the pump reverses the direction in which it pushes oil through the motors. The shuttle valve on the motor shifts to block oil on the high-pressure side and allow oil from the low-pressure side to flow through the motor relief valve.

Hydraulic systems - Hydraulic systems
Hydraulic systems - Overview The overall hydraulic distribution system on the self-propelled (SP) windrower comprises two major subsystems. The hydraulic system supplies hydraulic power to the header drive motors, header lift cylinders, and optional header tilt and flotation trim functions, while the hydrostatic system supplies power to the ground drive motors on the front wheels and controls the relative speed and direction of the drive motors. NOTE: For more detailed information on the hydrostatic drive system, refer to Hydrostatic transmission - Static description (29.202) of this manual. The H8040 windrower uses the engine to supply power for both on board and accessory hydraulic systems. Power for the hydraulic ground drive is provided by a tandem piston pump, mounted on the Left-Hand side of the front of the engine flywheel housing. The hydraulic header lift function is powered by a single gear pump, mounted on the front end of the ground drive piston pump.
DANGER Pressurized system! Always remove all pressure before working on the hydraulic system. Follow the pressure BLEED program in the Configuration Mode to remove the pressure in the entire hydraulic system. Failure to comply will result in death or serious injury. D0035A
Power for the hydraulic header drive is provided by a single gear pump, mounted on the Right-Hand side of the front of the engine flywheel housing. Both pumps are mechanically driven by a spur gear train, connected to the engine flywheel and contained in the transfer case (the front section of the engine flywheel housing). All of the hydraulic pumps draw their supply from the main hydraulic reservoir, mounted on the Right-Hand side of the chassis frame between the cab and the engine compartment. The reservoir is equipped with two 20-micron return-line filters, mounted on the upper outboard side of the reservoir. The rear filter only handles the return line from the oil cooler, which is connected to the header drive pump return line. The front filter is used for pump and motor case drains. All of the hydraulic header lift and ground drive functions are controlled through the Control Valve manifold. This valve is mounted on the main hydraulic component bracket, located on the forward Right-Hand side of the engine compartment outboard of the hydraulic pumps. Power supplied by the auxiliary pump is controlled through a dedicated auxiliary control valve (manifold), mounted above the main valve manifold on the main hydraulic component bracket.

Hydraulic systems - Hydraulic symbol Hydraulic diagrams are made up of a group of common symbols designed to represent actual components. You need to be familiar with these symbols in order for a hydraulic diagram to have any meaning to you. If you know what the symbols mean and how to interpret them, a diagram can be very useful in understanding how a system works. And that can help in diagnosing problems when things are not working as they should. Review the following symbols and the explanation of how to read valve symbols. You can then apply them to the system diagram that follows.
RESERVOIR- Vented
PUMP-Fixed displacement
PUMP - Variable displacement
MOTOR - Fixed displacement
CHECK VALVE
Check valve symbols sometimes cause confusion as to which way oil flows. Look at the symbol as two parts a ball and a seat in the shape of a "V". When oil flow pushes the ball towards the seat, the check valve is closed and there is no flow in that direction. When oil flow pushes the ball away from the seat, the check valve is open and oil can flow in that direction.

CONTROL VALVES
While most symbols are easy to understand, control valve symbols are somewhat more complicated as they have to be able to show the type of valve as well as how it directs oil flow. Since valves have internal parts that move so they can do their work, you have to be able to "read" that movement in the symbol to understand how a valve works. Let's look at how to "read" a number of different control valve symbols and be able to understand how the valves direct oil flow.

This is a symbol for a directional control valve. Each part of the symbol represents a characteristic of the valve. The symbol always represents the valve in its neutral or de-energized position.

The three items on each end of the valve tell you the following. (1) Solenoid (2) "B" Solenoid (3) Spring Now you know the valve is controlled by electric solenoids, that each solenoid is identified by a letter, and that the valve spool has a spring on each end which centers the spool when the valve is de-energized.
Here is how to read the center section of the symbol. Remember that the valve is still in its neutral, or de-energized, position at this point. A = Work port B = Work port P = Pressure port (Inlet) T = Tank port (Outlet) D = Closed passage While ports A and B will always be on one side of the symbol and P and T on the other, they will not always be in the same positions as shown in this example. Tracing the hydraulic lines to and from the valve will make it obvious which port is which. The arrows represent passages in the valve and are the key to understanding how the valve works. When the valve is energized, you need to visualize the arrows moving to the center of the valve and opening passages between ports.

When the 'A" solenoid is energized, the valve spool shifts to the left (away from the solenoid). Oil from the Pressure port flows to the A work port and oil flows from the B work port out the Tank port.

When the "B" solenoid is energized, the valve spool shifts to the right and the oil flow is reversed. Now oil flows through the valve from P to B and from A to T.
This valve is very similar to the prior example, but look at the ports. In this valve, ports P and T are joined when the valve is in neutral. This means that oil can pass through this valve and on to another component when the valve is de-energized.
In this example, you can see that ports A and B are both joined to either P or T. Most often they will join port T, meaning that oil that flows out either A or B when the valve is energized, will return through T to tank when the valve is de-energized. You will find other types of control valve symbols in the hydraulic system diagram. Here is how to interpret them.

This symbol represents a solenoid controlled cartridge valve. The black triangle means the valve is pilot operated. Note there is a spring shown which keeps the poppet against its seat until the valve is energized. The check valve symbols mean the valve is closed when de-energized and will open for flow in one direction when it is activated. When found in a hydraulic diagram, the check valve symbols will show which direction oil flows. This is a normally closed valve.

Here is another normally closed cartridge valve. The only difference between this valve and the first one is that when energized, oil can flow through the valve in either direction.

This cartridge valve is normally open as indicated by the arrows joining the ports. Oil will flow through this valve when it is not energized. When the valve is energized, it closes preventing oil from passing through it and causing it to be diverted elsewhere.
Here we have a cartridge valve with a spool rather than a poppet and it works similar to the directional control valves shown earlier. The valve is normally open. When energized the spool shifts and redirects the incoming oil out a different port.

Hydraulic systems - Dynamic description Ground drive The H8040 windrower is propelled and steered by 2-speed adjustable-displacement hydraulic motors, one driving each of the vehicle's front wheels. Normal braking is achieved by controlling the speed of the drive motors. Steering is accomplished by controlling the relative speed of the drive motors, resulting in functionally infinite turning radii. The rotational speed and direction, and the relative speeds, of the drive motors are controlled through a hydrostatic linkage fully described in section 29 Pump Dynamic description (29.218). Each drive motor converts supplied hydraulic flow into mechanical torque, which is in turn directly transferred through the modular brake and the drive gearbox to its attached drive wheel. Each drive wheel is equipped with a modular parking brake, which engages the drive motor's splined output shaft and is sandwiched between the outer face of the motor and the inner face of the drive gearbox spindle when the motor is bolted to the gearbox. The brake output shaft is coupled to the main shaft on the gearbox. The parking brakes are spring-applied and hydraulically released, for safety. Hydraulic supply oil is drawn from the reservoir into the ground drive pump (1). The ground drive pump is, a tandem variable-displacement piston pump mounted on the Left-Hand side of the transfer case cover, on the forward end of the engine. The tandem pump is driven by the engine flywheel through the planetary pump-drive gear train, located inside the transfer case (2). The pump translates this input mechanical torque into hydraulic flow. From the pump's two tandem units, bi-directional supply/return lines direct the flow to and from the drive motors. NOTE: The forward unit of the tandem pump supplies the left-hand drive motor, and the rear unit supplies the righthand drive motor. 50051670NNN
Included in the tandem Ground Drive pump assembly is a fixed-displacement charge pump (3). The charge pump also supplies oil to the Control Valve manifold, to power the 2-Speed ('2SP'), Parking Brake ('BRK'), MFH Control ('P3'), and Tilt Extend ('P4') circuits.

When actuated, the 2-Speed circuit delivers hydraulic oil to cylinders in the ground-drive motors which mechanically shift the motors from low-speed to high-speed range. When de-energized, supply is blocked, and the circuit provides a path for the oil to return to tank as the drive motor shift cylinders return to their low-speed-range positions. The selection of low-speed or high-speed operation is controlled by a two-position rocker switch (1), on the operator console. When actuated, the Parking Brake circuit delivers oil to extend cylinders within the modular brakes which release the spring-applied brakes. When de-energized, supply is blocked, and the circuit provides a path for the oil to return to tank as the parking brakes are applied, whether intentionally or due to electrical failure. The Parking Brake is engaged and disengaged by actuating the two-position rocker switch (2)on the operator console. The MFH Control circuit (connected to the 'P3' port on the control manifold) provides a constant supply of oil to run the proportional valve and attached propulsion cylinder (see section 29 for a full description). The Tilt Extend circuit (connected to the 'P4' port on the control manifold) provides a constant supply of oil to the 'extend' side of the header tilt cylinder, mounted on the front frame cross member below the cab. This maintains an attached header in its normal operating position, and also cushions the cylinder action during its 'retract' stroke . The splined output shaft from the Ground Drive pump drives the Hydraulic Header Lift gear pump, which is mounted on the forward end of the Ground Drive pump housing. All hydraulic oil related to the ground drive run through the front filter before re-entering the main reservoir.

Hydraulic systems - Dynamic description HEADER DRIVE The windrower is equipped with a hydraulic subsystem that powers and controls the header which may be attached to the front of the machine. The onboard Header Drive system terminates in quick connect hydraulic fittings located on the Right Hand side of the unit, just below and forward of the cab. There are three connections: one 'A' line, one 'B' line, and one case drain line. These lines carry hydraulic power and control to (and from) the hydraulic motor mounted on the header implement being used with the windrower. The case drain lines connect with similar lines from the ground drive motors at the front filter inlet on the hydraulic reservoir. Hydraulic supply oil for the Header Drive is drawn from the reservoir by a branch of the same large line supplying the Ground Drive system described earlier. The Header Drive pump is a fixed-displacement gear pump with a maximum output capacity of 114 L/min (30 GPM) @ 3447 kPa (500 psi), and minimum output capacity of 100 L/min (26 GPM) @ 1806 kPa (262 psi)at maximum engine speed of 2300 rpm. The pump, 1, is mounted on the Right Hand side of the transfer case cover, and is driven by the engine flywheel through the spur gear drive, located inside the transfer case, 2. The pump translates this mechanical torque input into hydraulic flow.

The activation and direction of the header drive motor is controlled by a group of switches on the operator console. The header drive switch, (1), is a two-position, pull-start/ push-stop actuator. The header drive motor is turned ON by pulling upward on the yellow knob and releasing it. This switch will remain in the ON position until the motor is turned OFF by pushing downward on the yellow knob. The speed of the header drive motor is controlled by the engine speed. To increase the header drive speed, increase or decrease the engine rpm using the throttle lever, 2.

The header reverser switch, (3), is a two-position rocker switch. For normal (forward) running of the header drive, the FORWARD ('F') end of the switch remains depressed, as shown. Depressing the REVERSE ('R') end of the switch causes the header drive to reverse direction and run a short (3-second) timed cycle intended to help clear the header of debris. NOTE: To actuate the REVERSE cleaning cycle, the header drive switch must first be pushed OFF. The forward/reverse switch is then toggled to REVERSE to initiate the timed cycle. The clearing cycle may be repeated as necessary. If there is no input from either the header drive switch or the reverser switch, the system will stop the header drive motors. However, the header drive pump will continue to run as long as the vehicle engine is running. NOTE: The header drive system includes a seat interlock safety device. If the operator leaves the seat for more than 4 seconds, the header drive motor will stop. In this case, after returning to the seat the operator must cycle the header drive switch OFF and then ON to restart the header drive.

Hydraulic systems - Dynamic description Header Lift - Draper Equipped [YCG667001-]
The hydraulic Header Lift system is powered by a double gear pump (1) mounted on the forward end of the Ground Drive tandem piston pump (2) and driven by the piston pump’s output shaft. The Header Lift system is hydraulically separate from the Ground Drive system; the mechanical drive linkage is the only connection between the two. The Header Lift pump is a fixed--displacement tandem gear pump, with an output capacity of 20.4 l/min (5.4 US gpm) from each pump outlet at maximum engine speed of 2200 RPM . The pump draws supply oil from the outlet (S2) port on the main hydraulic reservoir and directs this supply to the inlet (P1 and P2) ports on the Independent Control Valve (ICV) manifold.
60043212
The Header functions, controlled by buttons on the control console and MFH (multi-function handle), include HEADER RAISE, (1), HEADER LOWER, (2), HEADER TILT FORWARD, (3), HEADER TILT REARWARD, (4), HEADER FLOAT — LEFT-HAND, (5), and HEADER FLOAT — RIGHT-HAND, (6). In the system’s NEUTRAL (de-energized) state, the supply oil is blocked by the Lift, Tilt Retract. The path to the tank-return gallery is open through the Master Control valve. In this state, the hydraulic supply is circulated out the filtered tank (T1) port and back into the reservoir through the front filter port. In this condition, the mass of the lift arms (and any attached header) works to attempt to extend both the RH and LH lift cylinders, as well as the tilt cylinder. Uncontrolled extension/lowering of the lift cylinders is resisted by the oil in the rod end of the cylinders; the path of this oil to return to tank is blocked by the Header Lift valve, Header Float Valve, Header Lower valve, and the needle valves.

Neutral State The Neutral State (de-energized) blocks oil in the rod end of the lift cylinders to hold header position. In this state only the proportional pressure regulator valves are energized. The oil supply from the lift pump circulates through the Master Valves Y-003 and Y-004 back to port F1, filter through port T1. The header is held up by Y-010, Y-009, Y-006, Y-005, and dump valves.
Header Lift When the “Header Lift� button is depressed, the following sequence occurs: 1. Header Float Valves Y-010 and Y-009 are turned off. Pressure regulator valves are de-energized. 2. Master Valves Y-003 and Y-004 are energized. 3. Header Lift Valves Y-006 and Y-005 are energized. 4. Oil flows into the rod end of the lift cylinders to raise the header. 5. Oil in the barrel end of the lift cylinders is forced back to the manifold through the T2 port. Once the switch is released, the systemreturns to the Neutral State. NOTICE: The two needle valves (6A [RH Accumulator Dump] and 6B [LH Accumulator Dump]) are used to remove pressure from the hydraulic system. These valvesmust be opened fully any time the hydraulic system is opened and work is performed, and must be closed for normal operation.
Accumulator Charge On the first lower cycle, after the tractor is started, the accumulator will be charged. NOTE: Operator must set flotation pressure (psi) using rocker switches on the Right Hand Console (RHC). 1. Master valves Y-003 and Y-004 are energized. 2. Pressure regulators Y-001 and Y-002 are energized to set point. 3. Accumulator charge valves Y-008 and Y-007 are energized. 4. Charge oil flows into the accumulators. Accumulators are charged to set point. Time to charge is dependent on engine RPM and set point. At the end of the accumulator charge, we return to the neutral state. 1. Master valves Y-003 and Y-004, and accumulator charge valves Y-008 and Y-007 are de-energized. 2. Pressure regulator valves Y-001 and Y-002 are energized but to 50% of the flotation set point. This allows them to respond quickly to either a raise or lower cycle, whichever is initiated next.

When the accumulator circuit pressures are reached, the Accumulator Charge valves and Master Control valves are de-energized, closing the accumulator circuits and diverting P1 and P2 supply oil to tank. The RH and LH Header Float valves (Y-010 and Y-009) are then energized, opening a path for oil on the rod sides of the lift cylinders to flow into the accumulator circuits. The header will fall until the oil pressure equalizes in the closed circuits between the rod sides of the lift cylinders and the blocked RH and LH Accumulator Check valves (Y-008 and Y-007]). This internal equilibrium creates the header “float” action.

Floatation/Accumulators The floatation weight of the header is adjusted by depressing the “Increase Float” or “Decrease Float” rocker switches located in the console. These switches adjust the current control for the Pressure Reducing Valves Y-001 and Y-002. Increasing the amount of current applied to the valve increases the pressure set-point. Increasing the pressure set-point will reduce the amount of weight the header applies to the ground (makes the header feel lighter). Similarly, decreasing the pressure set-point will increase the amount of weight the header applies to the ground (makes the header feel heavier). The floatation set-point pressures are displayed on the control screen. The Left and Right Accumulator Pressure Set-Points may be adjusted independently. This independent adjustment is required for headers that are not balanced. A higher set-point will be required for the heavy side of a particular header. The increased pressure will allow the header to lift and lower level. Also independent adjustment can be made to allow for cutting on uneven ground (i.e. irrigation borders). Increasing the floatation pressure on the side of the header running on the border will prevent the header from running too heavy and causing poor cut quality.
Increase/Decrease Floatation When the “Increase Float” or “Decrease Float” switches are depressed the following sequence occurs: 1. Master Valves Y-003 and Y-004are energized. 2. Pressure Reducing Valves Y-001 and Y-002 are energized by current control to set the required accumulator pressure. 3. Header Lower Valves Y-008 and Y-007 are energized. 4. Header Float Valves Y-010 and Y-009 are energized. 5. Oil flows between the rod end of the lift cylinder and the accumulator. 6. Pressure reducing valve balances the pressure between the accumulator and the rod end of the lift cylinder. 7. Header “floats” at required weight based on operator set-point. 8. Header Lower Valves Y-008 and Y-007 are turned off. (Approx. 5 seconds after Header Lower button was depressed). 9. Master Valves Y-003 and Y-004 are turned off.

Hydraulic systems - Dynamic description Header Tilt The Header Tilt Cylinder, located forward of and below the cab on the vehicle's centerline, is mechanically connected to the upper surface of the attached header. This cylinder determines the angle of the header relative to the ground by rotating the header upward or downward around its connections to the header lift arms. The Header Tilt Cylinder is controlled through a cartridge-type valve in the Control Valve manifold. The header tilt is maintained in any selected position by the equilibrium between oil on the base (extend) side of the tilt cylinder, supplied by the Ground Drive charge pump, and the oil on the rod (retract) side of the cylinder, blocked between the mass of the header and the normally-closed Tilt Retract valve (Y-013). This is the condition shown in the Header Lift NEUTRAL state, described previously. When the HEADER TILT UP switch is actuated, the system energizes the Tilt Retract valve (Y-013), opening a direct path between the P1 inlet port and the TLT outlet port on the Control Valve Manifold. The RH Master Control valve (Y-003) is also energized, closing the direct path for the supply oil to return to tank and providing 238 bar (3400 psi) relief valve protection for the circuit. Pressurized supply oil from the Header Lift pump flows through the manifold and fills the rod end of the Tilt Cylinder, retracting the cylinder and tilting the header upward. The retraction of the Tilt Cylinder is throttled by the charge pressure on the cylinder base side of the circuit. (Excess pressure on this side of the circuit is directed out the port through the Ground Drive Charge Pump Relief to tank.) When the HEADER TILT DOWN switch is actuated, the Tilt Retract valve (Y-013) is energized, opening a flow path through the valve However, in this state the RH Master Control valve (Y-003) remains de-energized, directing supply oil from the manifold's P1 port through the valve to the tank-return gallery and out port T1. The Ground Drive charge pump supplies oil which fills the base (extend) side of the Tilt cylinder as the mass of the header forces the oil out of the rod side of the cylinder. The header tilts forward/downward as the oil from the rod side of the cylinder flows into the TLT port on the manifold and joins the P1 supply flow out to tank. When the HEADER TILT switch is released, the Tilt Retract valve and Right-Hand Master Control valve are de-energized, returning the circuit to its NEUTRAL state and stabilizing the header in its new position.

A single suction hose on the right-hand side of the pump draws hydraulic oil from the lower inboard side of the reservoir. The outlet port on the left-hand side of the pump direct the pump’s output to the header lift circuit.

Hydraulic systems - Overview GENERAL The keys to isolating and fixing a problem with the header drive system are proper test equipment and a thorough knowledge of how the system works.With proper maintenance, the header drive system should provide long, trouble-free service. If a problem develops, check the most obvious possibility first. The most common symptoms of trouble in a hydraulic system are overheating and excessive noise. These usually indicate a defective component. If overall system performance lags, check its pressure and flow.
Reduced System Pressure A reduction of system pressure will generally reduce the torque output of the system. A machine that cannot continue a heavy cut for more than few seconds may have low system pressure.
Reduced Hydraulic Flow Low hydraulic flow will usually reduce the power of the system. A machine with low hydraulic flow may not be able to maintain its cutting speed even with a light load.
Excessive Noise Always investigate any excessive or unusual noise immediately. Noise in the hydraulic system usually indicates cavitation (air in the system) caused by a restricted inlet, excessive fluid aeration, or worn internal parts. Air in the system, indicated by a milky appearance, usually comes from a leak on the intake (suction) side. Abnormal vacuum readings for the charge pump indicate restrictions in the inlet lines, filter and other suction-side components. In addition, worn inlet hoses may collapse internally, restricting inlet flow. Low pressure at the pump inlet port causes cavitation. A worn or failed charge pump is the primary cause of cavitation in the closed loop of the header drive system. In addition, if the charge pump relief valve or check valve on the main system relief valve malfunctions, the header drive pump will cavitate, causing it to slow and operate erratically. Use pressure and vacuum testing to properly diagnose these problems.

Hydraulic systems - Hydraulic systems
Overheating The temperature of the hydraulic fluid in the reservoir should not exceed 93.3 °C (200 °F). Overheating causes fluid breakdown and loss of lubrication, which in turn causes even more overheating, wear and leakage. Overheating can damage the system components. If the header drive slows after running for a while, check the temperature by immersing a standard thermometer in the reservoir fluid. Maintaining the correct level and quality of the fluid also is important because the hydrostatic and header drive systems share a common reservoir. Thus, fluid breakdown can damage both systems.
Power Loss Among the causes of power loss in the header drive system are: • Poorly adjusted controls. Always check this before troubleshooting the header drive pump, motor(s) and other components. • A defective high-pressure relief valve. If the valve fails to open, the fluid cannot return to the reservoir from the high-pressure side of the system. • Internal leakage, caused by wear or faulty seals and components. • Cavitation (see “Excessive Noise” above), usually due to inadequate charge pressure. • Internal slippage or external leakage, which allows the fluid to flow back into the reservoir rather than generating full power.

Hydraulic systems - Dynamic description EXPLANATION OF TERMS USED IN FAILURE ANALYSIS Lack of Lubrication The loss of the fluid film between the surfaces of moving parts. This causes metal-to-metal contact and smearing or galling of the parts. The extent of the damage will depend upon how long the unit ran without lubrication. Severe conditions that cause the loss of lubrication also may damage the components.
Operating at Excessive Temperatures (Overheating) Hydraulic fluid becomes thinner as its temperature increases. Operating with fluid at more than 93.3 °C (200 °F) can cause the lubricating film of fluid to become too thin. This allows metal-to-metal contact between parts, resulting in wear and damage to the running surfaces.
Use of Improper Fluid Always use the proper fluid as noted in specifications. Using fluid that lacks the proper lubricating and load-bearing characteristics can result in damage to the system and its components.
Cavitation Excessive amounts of air or foam in the fluid can replace the lubricating film, resulting in metal-to-metal contact and damage to the running surfaces of the components.
Abrasive Contaminants Dirt and other abrasive material in the fluid will damage the running surfaces.
Overspeeding Running the header drive too fast causes components within the pump and motor to separate. This places an excessive load on the bearing plate and slippers. The initial indication of this is a rolling on the outer foot of the bearing plate and the outer edge of the slipper face. Repeated overspeeding will destroy the lubricating film of fluid and cause damage to the system.

Hydraulic systems - Hydraulic systems
Parts Worn or Scored from Contamination Abrasive contaminants in the fluid cut tiny grooves in the bearing materials as they pass through the system. The damage occurs while the system is running. Fluid flow often flushes the abrasive particles out of the pump and motor and into the reservoir. Thus, it is difficult to tell which type of abrasives caused the damage. Service technicians typically can only inspect the components and assess the damage. They usually cannot determine which abrasives actually caused it. Working in a clean environment, cleaning the lines and components thoroughly prior to installation, using only clean fluid, and keeping the inlet screen and filters in good condition are the keys to avoiding abrasive contamination.
Plates Scored From Water in the Fluid Water and other liquid contaminants can react with additives in the hydraulic fluid, causing unwanted chemical changes. The contaminated fluid then reacts with the brass in the components and fittings, etching the finely finished surfaces. The etching removes material from the surfaces, opening up internal leaks and eventually rendering the unit inoperable.

Hydraulic systems - Dynamic description PARTS EVALUATION After removing a component from the header drive pump or motor, clean it. This will enable you to inspect it and accurately assess its condition. Clean the components using a solvent wash. Air drying is acceptable, provided that the solvent wash was clean.
Discoloration Overheating and chemical reactions are the most common cause of discoloration. Discoloration caused by overheating on the face of the slippers, bearing plates, or valves will warp the plates. Replace any warped plates. Discoloration caused by a chemical reaction will usually appear as a chemical build-up on the wear surface, or it will have an etched appearance. If you can remove the chemical build-up or etching with a minimal amount of touch lapping on a flat surface, rework and reused the parts. If not, replace the parts.
Scratches or Grooves Slippers, bearing plates or valves with scratches around their circumference or grooves on the running surfaces indicate abrasive contaminants in the hydraulic fluid. If you can remove the grooves or scratches with minimal polishing or touch lapping, rework and reuse the part. If not, replace it.
Rework Use a 4/0 grit paper on a flat lapping table (keep the table flat) to polish or touch lap of any of the flat surfaces of the parts. Polish parts using polishing solvent or its equivalent. NOTICE: Do not polish parts without using a polishing solvent or its equivalent.
Repeat Failures Diagnose and correct the cause of all problems and failures before reusing the parts, reassembling and installing a component, or operating the header drive system. Failure to find and eliminate the source of the problem will result in repeated equipment failures and additional repair and replacement cost.

Hydraulic systems - Dynamic description - Zero-Leak Plugs The aluminum hydraulic control valve uses Zero-Leak plugs in most locations requiring plugs. When leaks occur at the Zero-Leak plug locations, the problem is usually a loosened fitting, a damaged o-ring or a damaged plug to valve seat area. Zero-Leak plugs are used in the standard SAE J1926 o-ring ports. But, unlike a standard straight thread o-ring fitting typically used in these ports, the Zero-Leak plugs have a secondary seal of metal-to-metal contact of the plug against the o-ring chamfer in the port. Since the metal-to-metal seal in the chamfer takes up space, a much smaller cross section than standard o-ring is used on Zero-Leak plugs. NOTE: The special o-rings on the Zero-Leak plugs are not serviced separately. If an o-ring failure occurs, order and install new Zero-Leak plugs, as they have o-rings installed. Placing an o-ring that is too large onto a Zero-Leak plug will risk damage to the o-ring and a failure to achieve the required metal-to-metal contact when the plug is torqued to specification. O-rings for the Zero-Leak plugs are not available separately. Do not attempt to replace the o-ring on Zero-Leak plugs. Failure of the o-ring may indicate that the metal-to-metal contact seal has somehow been compromised.
DANGER Pressurized system! Always remove all pressure before working on the hydraulic system. Follow the pressure BLEED program in the Configuration Mode to remove the pressure in the entire hydraulic system. Failure to comply will result in death or serious injury. D0035A

Hydraulic systems - Service instruction Start-Up Procedure WARNING Avoid injury! Performing the following procedure may require the machine be disabled (work function disconnected, wheels raised off the ground, etc.). Failure to comply could result in death or serious injury. W0992A
Follow this start-up procedure any time you remove the pump or motor from the system, whether for replacement or service. 1.
Inspect the pump or motor for shipping damage prior to installing it. All system components (reservoir, hoses, valves, fittings, heat exchanger, etc.) should be clean prior to filling them with fluid.
2.
Fill the reservoir with hydraulic fluid passed through a 10-micron (nominal, no bypass) filter. Fill the inlet line leading from the reservoir to the pump prior to start-up. Tighten the fittings properly and keep the inlet line free of restrictions and air leaks.
3.
Fill the pump and motor with clean hydraulic fluid prior to start-up. Fill the housing by pouring filtered hydraulic fluid into the upper case drain port.
4.
Install a 6895 kPa (1000 psi) pressure gauge in the charge pressure port to monitor charge pressure during start-up.
5.
Disconnect the fuel solenoid wire from the injection pump to keep the engine from starting.
6.
Crank the engine until charge pressure shows on the gauge. Recheck the oil level in the hydraulic reservoir before starting the engine.
NOTICE: Do not continuously operate the starter motor for more than 30 seconds at a time. Let the starter motor cool for at least two minutes after operating for 30 seconds. 7.
WARNING Unexpected machine movement! Do not start the engine unless the pump is in neutral position (0 degree swash plate angle). Disconnect the motor output shaft or raise the drive wheels to prevent machine movement in case the pump is activated during initial setup. Failure to comply could result in death or serious injury. W1007A
Once the pressure gauge indicates charge pressure, reconnect the fuel solenoid wire and start the engine. With the engine running, minimum charge pressure should be 2275 kPa (330 psi). If the charge pressure is too low, shut off the engine and determine the cause of the problem.
47487694-35.000 17/01/2013
35.1 [35.000] / 77
Hydraulic systems - Hydraulic systems
8.
If necessary, bleed excess air from the high-pressure lines through the high-pressure gauge ports.
9.
Recheck the oil level in the hydraulic oil reservoir before operating the hydraulic system.
10.
Start the engine but do not allow the header drive to rotate.
11.
With the engine running at 2300 rpm, run the header forward. The header should stop when the header drive pump is in neutral. Charge pressure at the pump should remain at 2275 kPa (330 psi) with the header drive in forward. The high-pressure ports on the pump should be at equal pressure with the header drive in neutral.
12.
Continue to cycle the header drive between forward and reverse (if equipped) for at least five (5) minutes.
13.
Shut off the system, remove the gauges and plug the pressure gauge ports
14.
Check the hydraulic fluid level in the reservoir and add fluid as needed. The header drive system now is ready for use.

Inspect the fluid for the presence of water (indicated by a cloudy or milky appearance, or by standing water in the bottom of the reservoir). A rancid fluid odor indicates the fluid overheated.
•
If the fluid overheats or accumulates dirt, water or other contaminants, change the fluid.
•
Never reuse hydraulic fluid.
Cooling Circuit Bypass Pressure Under the right-hand motor door to the right of the battery, the cooling circuit bypass relief valve, (1), opens when the outbound, “hot” side exceeds the inbound, “cool” side by 552 kPa (80 psi). To check relief valve function, install a 2068 kPa (300 psi) pressure gauge in the cooling circuits. The pressure in the inbound side is set at 1793 kPa (260 psi). The outbound side sends fluid past the relief valve starting at 2344 kPa (340 psi). If the pressure difference between the two sides exceeds 552 kPa (80 psi), inspect and replace the relief valve.

Hydraulic systems - Measure TEMPERATURES The system uses a petroleum based hydraulic fluid. The following temperatures refer to the hottest point in the header drive system, which will usually be at the case drain ports of the pump and motor. Read the temperature by measuring it at the case drain ports of the pump and the motor. NOTE: Check pressure readings with the temperature of the hydraulic oil in the reservoir at 50 °C (122 °F). Normal (system) operating temperature range: 35 - 77 °C (95 - 171 °F) Maximum continuous temperature: 82 °C (180 °F) Maximum intermittent temperature: 104 °C (219 °F) Minimum intermittent temperature - cold start: -40 °C (-40 °F).

Hydraulic systems - Service instruction General Clean the exterior of all components before disassembly and repair. Dirt and dust will reduce the efficient working life of a component and lead to costly replacement. NOTE: Contain all fluid. Properly handle and dispose of all hazardous materials. Do not spill fluid onto the ground or floor during service. Minimize the amount of fluid that leaks or spills onto the machine. Catch as much fluid as possible, without contaminating other materials, and use the most efficient method of handling and disposing of waste. Time spent on the preparation and cleanliness of the work area will make the job safer and easier, and will result in repaired components that last longer and perform better. Use cleaning fluids that are safe and do not damage O rings and other parts. Check all solvents to make sure they are suitable for the parts involved. Thoroughly clean all solvents and cleaning fluids from all components. Solvents or cleaning fluids left on components can quickly dissolve hydraulic fluid during reassembly and start-up, leaving the component without effective lubrication. This will result in damage to the component. If you cannot completely clean the solvent or cleaning fluid from the component, use new clean lubricant or an appropriate oil to flush the component before assembling it and putting it into use. NOTICE: Never reuse hydraulic fluid. Use only new, clean hydraulic fluid to flush and lubricate parts and refill the hydraulic reservoir. New hydraulic fluid is inexpensive compared to the potential cost of repairing or replacing parts damaged by using improper or contaminated fluid. Dirt and chemical residue in old storage containers can contaminate fluid. Moisture can condense and collect in storage containers as well. Always thoroughly lubricate all parts with new clean lubricant or hydraulic fluid before assembly or use. Lightly coat O rings with clean petroleum jelly. Do not use grease, as it may clog oil passages or restrict the movement of precision-fitted parts. Replace O rings, seals or gaskets whenever removing or otherwise disturbing them. Never mix new and old seals or O rings, regardless of condition. Clean all gasket sealing surfaces prior to installing new gaskets. Protect all exposed machined surfaces, threads, gasket surfaces, and sealing surfaces from dirt and damage. Plug, cap, or seal all open hydraulic lines, ports, and other parts to protect them from dirt and moisture. Cover and protect all component parts from dirt and moisture. Do not leave parts unprotected. Protect exposed parts from rust and other types of degradation and damage. Where the manual recommends a tool, always use the recommended tool for the job.

Oil Level NOTICE: Always check the fluid level in the hydraulic reservoir when the system is cold. Keep the fluid above the low point in the hydraulic reservoir. Fluid that is above the low point in the reservoir when hot will contract when it cools and may fall below the low point. The hydraulic reservoir supplies fluid to both the header drive and hydrostatic systems on the windrower, along with the header lift, flotation and trim cylinders. Even though these are closed systems, the amount of fluid in the operating sections can vary, depending which components are in use. For example, the total amount of fluid required by a hydraulic cylinder varies widely as the cylinder extends and retracts. Hydraulic fluid under pressure fills the space formerly occupied by the piston rod as the cylinder extends, and returns to the reservoir as it retracts. Other hydraulic components can also require varying amounts of hydraulic fluid depending on their use. Thus, a fluid level may be at a safe level when some components are not in use, or are using a minimum amount of fluid. This “safe� fluid level can drop to an unsafe level when all components use the maximum amount of fluid. NOTICE: Always check the fluid level in the hydraulic fluid reservoir both before and after any service procedure that lets fluid escape from the system. Keeping the fluid level within the acceptable range will help prevent cavitation, aeration, overheating, lack of lubrication, and possible damage to the hydraulic system.
Hoses and Tubes Always replace hoses and tubes with damaged cone ends or the end connections. When installing a new hose, loosely connect each end and make sure the hose fits its desired location, without kinking or twisting, before tightening the connection. Tighten the hose clamps enough to hold the hose without chafing but not so tight as to crush the ends. Keep the hoses clear of moving parts and replace any hoses and fittings that have moved from their original positions over time. A hose with a chafed outer cover will allow moisture to get into the system. Concealed corrosion of the wire reinforcement will then occur along the hose length and result in hose failure. Ballooning of the hose indicates internal leakage as the hose deteriorates. This condition can rapidly lead to hose failure. Kinked, crushed, stretched or deformed hoses generally suffer internal structural damage that restricts fluid flow, reduces performance and ultimately causes the hose to fail. Do not allow free-moving, unsupported hoses to touch each other or related working surfaces. This causes chafing and reduces hose life.
O Ring Flat Face Seal Fittings Observe the following procedures when repairing O ring face seal connections:

Hydraulic systems - Remove Zero-Leak plugs To remove Zero-Leak plugs from the hydraulic valve, the heads of the plugs must be tapped first using a punch and hammer inside of the hex in the plug, to “shock” the plug loose before removal. If a punch is too long to get into tight areas, carefully use the flat face of a hammer to tap the head of the plug. This step is extremely important for the removal of the plug to not strip the internal hex.

Hydraulic systems - Install Zero-Leak plugs Prior operation: Hydraulic systems - Remove Zero-Leak plugs (35.000) Install a new Zero-Leak plug into the port after first inspecting the o-ring chamfer area for any imperfections which may be causing a poor primary metal-to-metal seal. Torque all Zero-Leak plugs to the specifications shown on the Plug Torque Requirements chart. If the Zero-Leak plugs fail, even after they have been replaced with genuine Zero-Leak replacement plugs and o-rings then use the following next steps. Replace the Zero-Leak plug with a standard SAE J514 Straight Thread O-Ring Boss (ORB) plug which uses the o-ring to seal instead of the metal-to-metal seal. This plug may be more tolerant to imperfections in the chamfer area. See the Zero-Leak Plug to SAE J514 ORB Plug Cross Reference chart. NOTE: The torques seen on the chart for the plugs are higher than standard SAE torques, this is the CNH recommended for all plugs on SP windrower valve manifolds. If the plugs loosen and cannot be kept tight, the addition of LOCTITE® liquid thread locker is recommended. The plugs must be removed, and the oil drained and cleaned thoroughly away from both port and fitting mating surfaces. NOTE: Remove the T1 (Tank Port No. 1 Main Return to rear reservoir filter connection) from the hydraulic control valve block and plug the hose. This will cut the perpetual feed of supply oil to the valve allowing it to be drained thoroughly and cleaned without constant oil seepage. Use LOCTITE® 7649 PRIMER N solvent based, on both port and fitting thread surfaces to provide a proper cure on inactive metals. Allow a minimum of 5 min for the primer to dry at room temperature. Use LOCTITE® 243 thread locker with oil resistance (similar to Loctite® 242 LOCTITE® 242 but improved oil tolerance). Only 2 drops of LOCTITE® 243 applied to the threads of the plug is necessary. Excess LOCTITE® may cause contamination of the hydraulic system, and/or cause blockage of a passage within the manifold or valves. Torque the plug/s to the specified requirement on the torque chart. Allow to cure for a minimum of 1 hour to ensure proper activation of the LOCTITE® before use of the hydraulic system.

NOTICE: ALL cartridges must be installed using LOCTITE® 7649 PRIMER N solvent based primer, on both port and fitting thread surfaces to provide a proper cure on inactive metals. Allow a minimum of 5 minutes for the primer to dry at room temperature. Use LOCTITE® 243 thread locker with oil resistance (similar to LOCTITE® 242 but improved oil tolerance). Only 2 drops of LOCTITE® 243 applied to the threads of the cartridge is necessary. Excess Loctite may cause contamination of the hydraulic system, and/or cause blockage of a passage within the manifold or valves. Torque the cartridge(s) to the specified requirement on the torque chart. Allow to cure for a minimum of 1 hour to ensure proper activation of the Loctite before use of the hydraulic system.
DANGER Pressurized system! Always remove all pressure before working on the hydraulic system. Follow the pressure BLEED program in the Configuration Mode to remove the pressure in the entire hydraulic system. Failure to comply will result in death or serious injury. D0035A

NOTICE: ALL cartridges must be installed using LOCTITE® 7649 PRIMER N solvent based primer, on both port and fitting thread surfaces to provide a proper cure on inactive metals. Allow a minimum of 5 minutes for the primer to dry at room temperature. Use LOCTITE® 243 thread locker with oil resistance (similar to LOCTITE® 242 but improved oil tolerance). Only 2 drops of LOCTITE® 243 applied to the threads of the cartridge is necessary. Excess Loctite may cause contamination of the hydraulic system, and/or cause blockage of a passage within the manifold or valves. Torque the cartridge(s) to the specified requirement on the torque chart. Allow to cure for a minimum of 1 hour to ensure proper activation of the Loctite before use of the hydraulic system.

The valve manifold is an integrated hydraulic circuit that utilizes cartridge-type valves actuated by solenoids. The manifold concept replaces numerous conventional in-line valves with a compact and neat assembly offering greater economy of weight and space. Fewer potential leakage points than with conventional valves ensures cleaner and safer operation. The modular design also provides for faster, easier servicing and troubleshooting. The manifold block is made from 6061 aluminum and is sulfuric anodized. The cartridge valves have a zinc plated finish; thus, both the manifold and valves are extremely corrosion-resistant. Some additional information concerning the modular design: • The cartridge design life is 25 million cycles. • The coils are designed for 10,000 hours of continuous use at their rated voltage. • The wet-armature, screw-in core tube design of the cartridge valves allows coils to be changed without removing the valve from the manifold. • The manifold and all its associated parts are manufactured by Eaton Hydraulics.
Service Parts The needle valves have seal kits (external seals only). There are no serviceable parts inside the valves. The cartridge valves have seal kits (external seals only) and coil kits. There are no serviceable parts inside the valves.
Valve Identification Codes All of the major components and ports are identified with code letters stamped into the manifold.

Hydraulic systems - Pump control valves
Pump control valves - Dynamic description Cartridge Valve (solenoid Operated) This system includes both spool- and poppet-type, solenoid-actuated, screw-in cartridge valves to direct and control oil flow. Most of the cartridge valves are load-holding (or "blocking") valves, meaning that their purpose is to open and close a single flow path. This differs from the spool valves, which direct oil through multiple flow paths. Each valve consists of two main parts, a solenoid coil and a screw-in cartridge. While all of the coils are essentially the same (differing in electrical connections), there are several different styles of cartridges used. The valve cartridges themselves are self-contained, with the only serviceable parts being the external seals and the solenoid coils.
DANGER Pressurized system! Always remove all pressure before working on the hydraulic system. Follow the pressure BLEED program in the Configuration Mode to remove the pressure in the entire hydraulic system. Failure to comply will result in death or serious injury. D0035A

Both styles of valves allow flow in both directions when energized. One group of valves blocks flow in BOTH directions when de-energized. They include: Coil Y-006 Y-013
Cavity 4A 4B
Function Header Lift Tilt Cylinder Retract
This type valve has two ports, with the "in" port, (2), on the side and the "out" port, (1), on the inner end of the cartridge. When the solenoid is not energized, the flow from port (2) to port (1) is blocked, because the design of the poppet, (3), uses pressure from port (2) to hold the poppet closed. In this group, the pilot pin, (4), prevents pressure applied to port (1) from moving the poppet, blocking flow from port (1) to port (2). When the solenoid is energized, the armature moves up, shifting the pilot pin, (4), within the poppet and allowing the check disc, (5), in the end of the poppet to relieve internal pressure. This allows flow from port (2) to lift the poppet off its seat, opening flow from port (2) to port (1). Also, in the energized state, pressure applied to port (1) will directly lift the poppet off its seat in both groups of valves, permitting flow from port (1) to port (2).

Function Accumulator Charge Header Float
This type valve has two ports, with the "in" port, (2), on the side and the "out" port, (1), on the inner end of the cartridge. When the solenoid is not energized, the flow from port (2) to port (1) is blocked, because the design of the poppet, (3), uses pressure from port (2) to hold the poppet closed. Pressure applied to port (1) lifts the poppet off its seat, allowing flow from port (1) to port (2). When the solenoid is energized, the armature moves up, shifting the pilot pin, (4), within the poppet and allowing the check disc, (5), in the end of the poppet to relieve internal pressure. This allows flow from port (2) to lift the poppet off its seat, opening flow from port (2) to port (1). Pressure applied to port (1) will seat the check disc and directly lift the poppet off its seat, permitting flow from port (1) to port (2).

Three-way Two-position Spool Valve The following two cartridge valves used in the Control Valve Manifold function by shifting flow from one path to another path when energized: Coil Y-028 Y-023
Cavity 3A 3B
Function Parking Brake Release Drive Speed 2 Engage
This type of valve has three ports, with the "in" port, (1), on the end of the cartridge, and the two "out" ports, (2) and (3), on the sides. When the valve is not energized, the flow path is open between port (1) and port (2), with port (3) being blocked. When the solenoid is energized, the armature moves up, allowing pressure at port (1) to shift the spool, (4). This movement of the spool closes the path between port (1) and port (2), and opens the path between port (1) and port (3). Note that, although port (1) is regarded as the inlet port on these valves, in this application the energized state directs supply pressure into port (3)and routes it out of port (1) to the Parking Brake and Drive Speed (2) circuits.

The Auxiliary Speed Control (if mounted) includes one two-position solenoid-actuated normally open poppet-style DCV.
Two-way Two-position (Normally Open) Poppet Valve This valve is similar in construction and operation to the normally-closed valves found in the Control Valve Manifold, described earlier, except this valve allows two-way flow in its de-energized state, and shifts to block flow when energized. Coil Y-035
Cavity 5
Function ON/OFF Valve
This type valve has two ports, with the "in" port, (2), on the side and the "out" port, (1), on the inner end of the cartridge. When the valve is de-energized, flow is allowed in both directions. Pressure applied to port (1) closes the check disc, (3), in the poppet, (4), and lifts the poppet from its seat, allowing flow out of port (2). Pressure applied to port (2) enters the poppet through the small orifice, (5), unseats the check disc, (3), from the larger orifice, (6), and flows out of port (1). When the valve is energized, the armature pushes the pilot pin, (7), downward to close the large orifice, (6), in the poppet, (4). With this outlet from the poppet interior closed off, pressure applied to port (2) fills the poppet through the small orifice, (5), keeping the poppet seated and blocking flow from port (2) to port (1). Flow applied to port (1) lifts the poppet off its seat and diverts out through port (2), once it is sufficient to overcome the coil force seating the poppet.

The Control Valve Manifold also includes a basic type of solenoid-actuated normally-open screw in cartridge spool valves that control and/or relieve pressure.
(Normally Open) Pressure Reducing/Relieving Valves The proportionally controlled internally-piloted pressure reducing-relieving valve restricts inlet pressure to maintain a preset outlet pressure. Beyond a preset outlet limit, the valve relieves pressure to tank. Coil Y-001
Cavity 5A
Function Accumulator Pressure
This type of valve has three ports, with the inlet port (2), and relief/venting port (3), on the side of the cartridge, and the controlled-pressure outlet port (1), on the inner end. The solenoid coil, controlled by the accumulator charge increment/decrement buttons on the operator console in the cab, increases or decreases the target outlet pressure at port (1) by moving the armature. This allows a range of outlet pressure settings from 0 - 224 bar (0.0 - 3248.0 psi). The valve maintains an open flow path from port (2) to port (1). When the preset outlet pressure is attained at port (1), the spool (4), shifts to restrict inlet flow at port (2) to maintain the outlet pressure. Flow surplus to the outlet pressure requirement is vented out port (3) to tank. If the pressure at port (1) exceeds the current relief pressure setting of the valve (as when REDUCING the accumulator charge pressure), the spool shifts father and relieves flow to port (3).

(Normally Open) Solenoid-operated Relief Valves The normally-open solenoid-operated relief valve serves as a master control valve for the header drive. When energized, the control valves divert supply pressure into their assigned circuits AND serve as relief valve protection for that circuit's functions. Coil Y-030
Cavity 4
Function Header PTO Forward
This type of valve has two ports, with the outlet port, (2), on the side of the cartridge, and the inlet port, (1), on the inner end. In the valve's de-energized state, free flow is permitted from port (1) to port (2). When the solenoid is energized, the internal spool shifts, allowing flow from port (1) to port (2) ONLY when the factory-set pressure limit of 22063 kPa (3200 psi) is exceeded.

The Auxiliary Speed Control (if mounted) includes one normally-closed solenoid-operated spool type proportional flow control cartridge valve.
(Normally Closed) Solenoid-operated Proportional Flow Control This valve uses a varying current supplied to the coil to allow a range of flow rates from fully closed to full flow through the valve. Coil Y-029
Cavity 4
Function Proportional Flow Control
This type of valve has three ports, with the inlet port, (3), and outlet port, (2), on the side of the cartridge, and the pressure-balancing port, (1), on the inner end. Port (1) is always blocked in this application. The solenoid coil reacts to a varying supply current (controlled by buttons on the operator console in the cab) by moving the internal spool to allow a corresponding range of flow from port (3) to port (2). This flow rate will vary from 0 (fully closed), at 0 mA current, to 55 l/min (14.5 US gpm) at 1500 mA current.

The Auxiliary Speed Control (if mounted) includes a pilotoperated relief valve and a differential-pressure- sensing valve.
Pilot-operated Relief Valve An adjustable, pilot-operated relief valve is mounted in each Auxiliary Speed Control, to protect the controlled circuits. Cavity A3
Function Circuit Protection
This type of valve has two ports: the input port, (1), is on the inner end of the cartridge, and the outlet port, (2), is on the side. Flow is blocked from port (1) to port (2) until the predetermined pressure setting is reached at port (1). The spool, (3), then shifts, diverting flow out port (2).

Differential-Pressure-Sensing Valve A spool-type externally-piloted differential pressure sensing valve is mounted in the Auxiliary Speed Control and Header Control Manifold, to work with the proportional flow-control valve to produce pressure-compensated priority flow control. Cavity 2 2 3
Function Differential Pressure Sensing (Auxiliary Speed Control) Differential Pressure Sensing (Header Drive Manifold) Differential Pressure Sensing (Header Drive Manifold)
This type of valve has three ports, with the inlet port, (1), on the inner end of the cartridge, and the outlet port, (2), and pilot port, (3), on the side. Flow from port (1) to port (2) is normally blocked. Pressure applied to the pilot port (from the outlet side of the device being controlled) works together with internal spring pressure to resist the movement of the spool in the direction that opens flow from port (1) to port (2). As the pressure applied to port (1) INCREASES relative to the pressure applied to the pilot port, the spool, (4), will shift upward, opening an increasing flow from port (1) to port (2). Similarly, as the pressure applied to the pilot port INCREASES relative to the pressure applied to port (1), the spool will shift back to a position blocking flow from port (1) to port (2).

Hydraulic systems - Fixed displacement pump
Fixed displacement pump - Dynamic description - Auxiliary engine mounted gear pump (optional) Some options, such as hydraulic reel drive require a factory-installed auxiliary hydraulic pump, (1), which is mounted on the Right-Hand side of the engine on the rear gear housing, (2). The pump is driven by a PTO assembly, (3), which joins the flywheel and hydraulic pump. This installation also includes dedicated auxiliary suction and return lines, and an auxiliary control valve (manifold). The auxiliary hydraulic pump is a fixed-displacement gear pump with an output capacity of 51.8 l/min (13.7 US gpm) at maximum engine speed of 2300 RPM. The dedicated supply line connects the "S3" port on the main hydraulic reservoir with the inlet port on the auxiliary gear pump. The outlet port on the pump is connected to the supply ("P") port on the auxiliary control valve.

Before applying pressure, make sure all connections are tight and all components are in good condition. Never use your hand to check for suspected leaks under pressure. Use a piece of cardboard or wood for this purpose. If injured by leaking fluid, see your doctor immediately. Failure to comply could result in death or serious injury. W0178A

Reservoir lines Return lines - Troubleshooting - Header Drive Motor NOTE: In troubleshooting a pump-motor system, it is necessary to isolate the pump from the motor to determine which unit is malfunctioning. A worn pump or worn motor will each give the same symptoms. A flow meter could be installed into the pump output line to pressure flow check it, but a case drain flow check is much easier and should diagnose a problem. The following troubleshooting suggestions are based on the assumption that the pump is within operating specifications. Problem Possible Cause Motor turns while Scored back plate. unloaded but slows down or stops when load is applied. Scored connector plate.
Scored or worn piston shoes.
Low relief valve pressure. Motor will not turn.
Motor freewheels.
Rapid tapping noise in motor.
Severely scored back plate and connector plate. Contaminate particle holding connector off back plate. Oil flow and pressure going to motor are shut off.
Free-floating pistons seating on bearing race.
Excessive case drain flow. Excessive internal wear-in.
47487694-35.300 17/01/2013
35.5 [35.300] / 15
Correction Remove back plate and examine surface condition of flat area. If scored, replace back plate. Do not lap. Disassemble motor, check finish on connector plate and back plate, replace if necessary. Disassemble motor, examine condition of shoes on pistons, replace pistons as a complete set if necessary. Check relief valve for proper pressure setting, adjust or replace relief valve. Disassemble motor completely. Inspect all parts, clean all parts, replace all worn parts and flush hydraulic system. Disassemble motor, inspect and clean parts, replace necessary parts. When the hydraulic system is shut off, either by shutting off the engine on a closed loop system or returning the control valve spool to neutral on an open center system, the motor will freewheel after it has leaked off and allows the free-floating pistons to collapse. This is inherent in the design. On a closed loop or propulsion system, the motor will not freewheel as long as charge pressure is maintained to and from the motor. When oil flow to the motor is shut off and the motor allowed to freewheel, the freefloating pistons will collapse into the piston block. When oil flow is reapplied to the motor, the pistons will reseat themselves against the bearing race and will cause a rapid tapping sound. This is not harmful to the motor as long as the oil flow into the motor does not exceed 10 gpm for the first revolution of the motor. Disassemble motor, inspect parts and replace as necessary. Case drain flow should not exceed 1.5 gpm at full pressure.

Air filter - Cleaning With Air Clean the air filter if it shows an accumulation of dirt on the bottom side. Use one the following methods: Tap the filter gently on a flat surface with the dirty side down. Compressed air may be used if the pressure does not exceed 689.5 kPa (100 psi). Keep the nozzle at least 25 mm (1 in) from the filter surface. Direct the air through the filter, opposite to the air flow through the filter. Do not direct air against the dirty side of the filter because it will force dirt further into the pleats. The filter may also be washed. Soak the element for 15 min in a solution of lukewarm water and a mild non-sudsing detergent. Rinse the filter thoroughly with clean water from a hose having less than 275.8 kPa (40 psi)water pressure. Allow the filter to dry. NOTE: If washing filter to clean, do not use compressed air or heat to dry the filter.

Cab climate control - Air conditioning
Air conditioning - Dynamic description The Basics of Refrigeration Air conditioning is based upon the process of heat transfer. When a warmer object is placed next to a colder object, the warmer object will lose heat and become cooler and the colder object will absorb the heat and become warmer. The air conditioning system removes heat from the windrower cab and releases it to the outside air. Heat always flows from a warmer object to a cooler object. The intensity of heat is measured with a thermometer in degrees Celsius or degrees Fahrenheit. The quantity of heat is measured in calories or British Thermal Units (BTU’s). A BTU is the amount of heat needed to raise one pound of water one degree Fahrenheit. A calorie is similar to a BTU except it is measured in metric units. When enough BTU’s are added to or subtracted from a liquid, it will turn into a vapor or a solid. This is called a “change of state”.

For example, a pound of water at 212 °F must have 970 BTU’s added to change it to a vapor at the same temperature. As a substance changes state, it absorbs or releases large amounts of heat without changing temperature. Liquids absorb the greatest amount of heat when they boil. Therefore, the boiling point of a liquid refrigerant needs to be lower than the temperature of the area it is supposed to cool. Refrigerant R134A is used in most air conditioning systems because it has a very low boiling point ( -22 °F). As the R134A boils, it absorbs heat from the windrower cab until the cab is cooled. That is the essence of the air conditioning system.

There are five major components in a R134A air conditioning system: compressor, condenser, receiver/drier, thermal expansion valve and evaporator. Refrigerant is drawn into the compressor as a cool/cold low-pressure vapor which is compressed and discharged as a hot, high-pressure vapor to the condenser. The hot, high-pressure vapor passes through the condenser core and is cooled and condensed to a high-pressure liquid. The vapor gives off heat to the cooler air drawn through the condenser by the engine fan and is condensed to a cool, high pressure liquid. This cool, high pressure liquid passes through the receiver/drier without changing state. At the thermal expansion valve, the cool high pressure liquid passes through a metered orifice and enters the evaporator as a cold, low pressure atomized liquid or spray. The orifice provides a restriction to refrigerant flow that causes a pressure drop, atomizing the refrigerant to a spray while decreasing its temperature and pressure. At the atomized liquid refrigerant passes through the evaporator coils it absorbs heat from the air blown across the evaporator by the blower motor. In the process, the cold, low pressure atomized spray evaporates to a cool/cold low pressure vapor which exits the evaporator at the outlet. The low-pressure vapor is drawn into the suction port of the compressor, and the cycle repeats. The temperature difference between the atomized liquid as it enters the evaporator and the vapor as it exits the evaporator should remain constant, regardless of the ambient outside temperature in a normally functioning system. As the heat exchange occurs at the evaporator, moisture in the air condenses on the evaporator fins and drains off as water, reducing the humidity level in air circulated to the cab.

Air conditioning - Dynamic description R134A Refrigerant Information Prompted by environmental concerns, equipment is manufactured with non-ozone depleting air conditioning systems. The refrigerant used, R134A, has no CFCs (chlorofluorocarbons) and no chlorine molecule. R134A, a hydrofluorocarbon or HFC, replaces R12. R12 contains a chlorine atom which when released into the atmosphere depletes the ozone layer. All R134A A/C systems and the service equipment for them are equipped with unique fittings to prevent mixing refrigerants or using incompatible equipment. Storage containers and hoses for R134A have a unique color scheme and are equipped with the same fittings to prevent mixing. Connecting hoses, service ports and pressure switches are equipped with valves to prevent discharging refrigerant into the air. Windrowers have an R134A air conditioning system. The system functions in the same manner as previous systems with slightly higher operating pressures and a few component variations. NOTE: Follow all local and governmental regulations regarding the handling of HFC materials before performing any work on systems using HFC compounds.

Air conditioning - Dynamic description Refrigerant Ingredients Lubricants The refrigerant R134A and the lubricant used with it were developed as a system. R134A uses a lubricant made from polyalkylene glycol (PAG). NOTICE: The PAG lubricant used with R134A is NOT compatible with the mineral oil used in R12. Mixing the two lubricants can lead to early failure of the hoses, bearing shaft seals, and O-rings used in R134A systems due to hardening, swelling, or cracking of rubber parts. The lubricants used with R134A are far more aggressive to rubber parts than the mineral oils used with R12. When servicing this air conditioning system, use rubber parts approved for use with R134A and its oil.
Refrigerant ( R134A) The Self-Propelled Windrower uses R134A, an HFC refrigerant with effective cooling capabilities that is more environmentally friendly than older, CFC refrigerants such as R12. The air conditioning system contains 2.4 kg (5.3 lb) of R134A refrigerant. NOTICE: DO NOT mix CFC refrigerant with an environmentally safer material such as R134A. Air conditioning equipment is designed as a system. The refrigerant and its thermodynamic, physical, and chemical properties are a key factor in the overall system design. If you replace R134A with another refrigerant, your air conditioning system will perform poorly. Eventually, the compressor and other system parts will fail due to chemical attack, excess pressure, and poor lubrication.

Air conditioning - Dynamic description Blower Fan The blower fan is next to the evaporator. The fan draws warm air from outside the cab and forces it across the evaporator. The fan then blows the cooled air through the air duct and into the cab. A three-speed switch controls the blower motor (M-23) on manual HVAC units. Although the fastest blower speed moves the most air through the system, a slower speed gives the air more time to exchange heat for cold as it passes through the cooling fins and coils of the evaporator. Therefore, the lowest fan speed produces the coldest air, although in less volume than at high fan speed.

Air conditioning - Dynamic description Contaminants General No mobile air conditioning system can operate for long without picking up some contaminants in the refrigerant. The flexible hoses, for example, allow moisture and air to migrate into the refrigerant from the outside atmosphere. Moisture and non condensable gases (air) are the most common contaminants found in mobile air conditioning systems. NOTICE: Contaminating R134Awith R12 or CFC will lead to copper plating of steel components and major compressor failure. Lubricant and refrigerant that remain in service equipment can be contaminants. When you recover a refrigerant, you also will capture a certain amount of lubricant in the extraction or recovery equipment. The equipment will drain the lubricant in a catch bottle or reservoir for measurement and proper final disposal. Never use a lubricant that has come out of an air conditioning system. Reusing this oil will result in contamination of the air conditioning system with refrigerant, moisture and air from the old oil. Instead, refill the air conditioning system using fresh oil in the same amount as that removed during service. Dispose of the used oils in a manner that complies with federal, state and local disposal requirements. To avoid contamination between systems using dissimilar refrigerants, the extraction and recycling equipment MUST be dedicated to a single refrigerant.
Preventing Mixing of Service Equipment To help avoid the mistake of charging a system with an incorrect, incompatible refrigerant, the compressor fittings are different for refrigerants R12 and R134A. Systems using R134A have quick couple service connections, while R12 systems use screw threads. This prevents the use of the same tools for different refrigerants, thereby helping to avoid the mixing of refrigerants in service equipment. If refrigerants become mixed, the thermodynamic and chemical characteristics will change. This change results in excessive pressure and poor lubrication and leads to failure of the compressor, desiccant (drier) and other system components. Ultimately, system failure and an expensive repair bill will result if refrigerants become mixed in a single set of service equipment.

Air conditioning - Dynamic description Refrigerant Extraction and Recycling Equipment Both extraction and recycling equipment are in use and available to service technicians. Both types of equipment will remove the refrigerant from an air conditioning system. However, extraction equipment only pulls the refrigerant from the air conditioning system and stores it in an appropriate container. Extraction equipment does not clean the refrigerant. Its only purpose is to recover the refrigerant from an air conditioning system prior to disassembling and servicing it. Always recycle or reclaim recovered refrigerant before putting it back into an air conditioning system. During service operations involving a partial recharge, or while the air conditioning system is in use, refrigerant can pick up moisture, lubricants, microscopic metal chips, and other potential contaminants. In many cases the contaminants contribute to or are the primary cause of the system failure. Putting used, unclean refrigerant back into an air conditioning system may result in poor system performance. NOTE: Reuse of unrecycled, unreclaimed refrigerant will void the warranty. Equipment that removes refrigerant from a mobile air conditioning system (recovery equipment) may allow you to put the used refrigerant back in the system without first cleaning it to minimize performance. You may also use such conditioning systems. Non-mobile air conditioning systems use refrigerants and contain contaminants that are different from those in mobile air conditioning systems. Recovery equipment may therefore allow the mixing of different types of refrigerants or introduce contaminants that may not be removable by recycling equipment available in the service shop. If you want to remove, clean and reuse R134A refrigerant, you must use a machine that both extracts and recycles refrigerant from mobile air conditioning systems. Dedicate that machine to R134A only. Recycling equipment meeting SAE standards J1990 and J2210 is designed to extract and recycle refrigerants that have been in mobile air conditioning systems only. R134A refrigerant that also is used in non-mobile systems may introduce contaminants to the refrigerant that equipment meeting SAE J1990 and J2210 cannot remove. This equipment is not intended for use on non-mobile systems.

Using Extraction Equipment Extraction equipment is relatively small and easily portable. It is best used if a shop must service vehicles, such as agricultural or off-highway equipment, that cannot easily be brought into the shop. It is also convenient for shops that must deal with a variety of different refrigerant types and exchange recovered refrigerant at some central location. Always use extraction equipment on those refrigerants for which it was designed. The lubricants, hoses, and seals in this equipment have been designed to work with only one refrigerant. To help avoid a mix-up of service equipment and refrigerants, equipment hoses designed for use which each refrigerant are easily identifiable. New service hoses used with R134A must have a black stripe along the hose length and carry the designation “SAE J2196/R134a” (hoses labeled “SAE J 2196” and lacking the black stripe were used for R12.) If you use extraction equipment and send your recovered refrigerant to a reclamation facility, reclaimed refrigerant you purchase must meet the Air Conditioning and Refrigeration Institute standards of purity (ARI Standard 700-88). This will ensure that the refrigerant you are using not only meets the purity requirements of SAE J1991 (for R12) OR J2099 (for R134A), but also that it does not contain incompatible lubricants or other contaminants from non-automotive air conditioning systems.
Using Recycling Equipment Recycling equipment extracts and removes common contaminants from refrigerants. Recycling equipment designed and certified to meet SAE standards can make refrigerant recovery from mobile air conditioning systems suitable for reuse in automotive air conditioning systems. Like extraction equipment, SAE standards require that each piece of recycling equipment be dedicated to a single refrigerant. NOTE: Only equipment capable of recovering and cleaning R134A to meet SAE J2099 purity levels carries a label with the phrase “Design certified by Underwriters” Laboratories, Inc. for compliance with SAE J2099. The Underwriters’ Laboratories label must be specific that the equipment is “design certified” for the SAE J2099 standard. If not, it certifies only that the machine is free of reasonable shock or other electrical hazards to the user.
Recycling vs. Reclaiming Recycled refrigerant has been recovered from a mobile air conditioning system and is cleaned by the same shop that recovered it to meet J2099 for R134A. The equipment designed to recycle refrigerant in the shop environment removes only contaminants picked up during the operation of a mobile air conditioning system. Refrigerant that is either properly recycled or reclaimed is adequate for use in mobile air conditioning systems.

Air conditioning - Dynamic description Refrigerant Oil General Since the refrigerant is recovered as a gas, during a typical recovery only about 25 % of the oil in the vehicleâ&#x20AC;&#x2122;s A/C system is recovered and separated. The other 75 % remains in the closed system normally on the low pressure side. (These percentages are representative and will vary from recovery unit manufacturer to manufacturer.) The only reliable method for determining if the A/C system has the correct amount of oil is the dipstick method. Too much oil in the closed system causes poor condensation and reduced cooling since the oil accumulates on the evaporator and condenser surfaces. Too little oil in the system causes poor lubrication which equates to poor refrigerant circulation and reduced compressor efficiency and high pressures. Both conditions cause more system wear and shorter system life. During normal servicing - recovery, evacuation and recharge, oil is simply injected back into the system during the recharge process. Before recharging, use the dipstick method to check the compressor oil level or to adjust oil level. NOTICE: If a new compressor is installed, its oil level must be adjusted to match the oil volume of the removed compressor. NOTE: CNH PAG OIL (Sanden SP-15) PAG oil must be added whenever a component is replaced.

Air conditioning - Dynamic description Contaminants No mobile air conditioning system can operate for long without picking up some contaminants in the refrigerant. The flexible hoses, for example, allow moisture and air to migrate into the refrigerant from the outside atmosphere. Moisture and non-condensable gasses (air) are the most common contaminants found in mobile air conditioning systems. Lubricant and refrigerant that remains in service equipment can be a contaminant. The lubricant may have absorbed some moisture and air that has migrated into the air conditioning system. Some of the lubricant is captured by and carried along with the refrigerant. When you recover a refrigerant, a certain amount of lubricant will be captured by the extraction or recovery equipment as well. This lubricant will be drained into a catch bottle or reservoir for measurement and proper final disposal. Lubricant that has come out of an air conditioning system should never be reused. Reusing this oil may result in contamination of the air conditioning system with the refrigerant, moisture and air that has been temporarily absorbed into the oil. Instead, the A/C system should be refilled with the same amount of correct fresh oil that was removed in the service operation. The used oils must be disposed of in a manner which complies with federal, state and local disposal requirements. NOTE: CNH has decided that the proper PAG oil viscosity for all locations/markets is ISO 68. This is available as CNH PAG OIL for R134A refrigerant, and is Sanden SP-15. To avoid contamination between systems using dissimilar refrigerant, service equipment MUST be dedicated to a single refrigerant.

All components in an air conditioning system are connected by hoses through which refrigerant circulates. To ensure that the system cools the cab properly, each component must be in good operating condition.
Compressor Pump The air conditioning unit has a compressor pump, (1), mounted inside the engine compartment that is belt driven by the crankshaft pulley. The compressor separates the low and high pressure sides of the system and has two functions: 1. To raise the refrigerant pressure and temperature by compression to a higher pressure and temperature than the outside air. 2. To circulate the required volume of refrigerant through the system.

High-pressure Cutout Switch (S-040) The high-pressure switch (S-040), (1), is located in the receiver/drier outlet line. Excessive refrigerant pressure may occur due to a faulty expansion valve or icing up of the expansion valve orifice. Excessive pressure will result in severe damage to the compressor pump. The purpose of the high-pressure switch (S-040) is to shut off the compressor pump in case of excessive pressure in the refrigerant system.

The low-pressure switch (S-039) is behind the cover of the HVAC box. Loss of refrigerant in the system will result in insufficient cooling and continuous operation, which in turn could lead to possible damage to the compressor pump.

Air-conditioning condenser - Dynamic description The condenser, (1), is in front of the charge air cooler, (2), and consists of a number of turns of continuous coil mounted in a series of thin cooling fins. Hot refrigerant vapor under pressure flows from the compressor to the condenser. Air passing over the condenser coils cools the refrigerant, causing it to revert from a vapor to a liquid. This change of state (from vapor to liquid) releases a large quantity of heat, which passes to the outside air through the condenser.

Receiver/Dryer - Dynamic description The warm liquid refrigerant flows from the condenser into the receiver/drier, (1). It passes through a filter and desiccant (drier) and into an outlet line to the thermostatic expansion valve. The refrigerant enters the thermostatic valve as a high-pressure WARM LIQUID. Its pressure and temperature fall as it passes through the metering orifice and it becomes a low-pressure COLD VAPOR AND ATOMIZED LIQUID. The receiver/drier, (1), is a storage tank that receives the high-pressure warm liquid refrigerant from the condenser and delivers the refrigerant to the thermostatic expansion valve. The receiver section stores liquid refrigerant to maintain a steady flow to the thermostatic expansion valve under widely differing operating conditions. The drier section contains a desiccant to absorb any moisture within the system and a filter to keep dirt from damaging internal components. NOTICE: Any moisture in the air conditioning system is extremely harmful. Moisture not absorbed by the drier will circulate with the refrigerant, and droplets may collect and freeze in the thermostatic expansion valve orifice. This action will block the refrigerant flow and stop the cooling action. The desiccant can absorb only a limited amount of moisture before reaching its saturation point. Its ability to retain the moisture is dependent upon temperature. As the temperature increases, its ability to absorb moisture decreases. Therefore, an air conditioning system may operate satisfactorily when outside temperatures are low but stop cooling when ambient temperatures increase and the saturated desiccant releases moisture into the system.

Expansion valve - Dynamic description The expansion valve, (1), is on the pressure line leading from the dehydrator and receiver into the evaporator and performs the following functions: • METERING ACTION - A metered orifice changes the liquid refrigerant from high to low pressure. • MODULATING ACTION - A thermostatically controlled valve within the expansion valve body controls the volume of liquid refrigerant passing through the orifice and makes sure the refrigerant is fully vaporized within the evaporator. Liquid refrigerant would damage the compressor reed valves or freeze the pistons. • CONTROLLING ACTION - The valve responds to changes in the cooling requirements. When increased cooling is required, the valve opens to increase the refrigerant flow. When less cooling is required (or high engine speed provides increased compressor volume) the valve closes and decreases the refrigerant flow.

Operation All of the necessary temperature-sensing and pressuresensing functions are consolidated into this basic unit, and no external tubes are required for these purposes. The block or “H” type expansion valve gets its name from its construction. Two refrigerant passages form the legs of the “H”. One passage is in the refrigerant line from the condenser to the evaporator and contains the ball, (1), and spring valve, (2). The other passage is in the refrigerant line from the evaporator to the compressor and contains the valve’s temperature sensing element, (4). With the system shut off, the pressure on the bottom of the expansion valve diaphragm, (2), rises above the pressure on the top of the diaphragm, (1). This allows the valve spring to close the valve, (3).

Cab climate control - Air conditioning
With the system running, the pressure on the bottom of the diaphragm drops rapidly. This allows the valve to open and send liquid refrigerant to the lower evaporator tubes, where it begins to vaporize. The compressor suction draws the vaporized refrigerant out of the top of the evaporator at the top tube where it passes the temperature sensor. Cooling reduces pressure in the temperature sensor and begins to close the expansion valve. Superheating in the evaporator raises the pressure and opens the expansion valve. This allows more refrigerant to flow. At high pressure, the diaphragm flexes upward and pulls the thermal element and pushrod away from the ball seat of the expansion valve. The expansion valve spring forces the ball onto the tapered seat and the liquid refrigerant flow decreases. At low pressure, the diaphragm flexes downward and opens the expansion valve to provide the required pressure and refrigerant.

Air conditioning - Service instruction And General Safety Review the material safety data sheet provided by the refrigerant manufacturer for safe and proper handling information as well as instructions on what to do if an emergency should arise. Read and understand the applicable material safety data sheet before you begin work on an air conditioning system. Likewise, your service equipment comes with a thorough set of operating instructions that should allow you to perform refrigeration system service work easily, efficiently and safely. Read and understand your service equipment before you start work. The following safety warnings are generally recognized as minimum precautions that you must follow when servicing air conditioning systems. 1.
Be familiar with the operation of the Windrower.
2.
Read, understand, and follow the instructions provided by the manufacturer of all the service equipment with which you will be working and operation of the Windrower.
3.
Wear safety goggles at all times when servicing an air conditioning system, extraction or recycling equipment, or otherwise handling refrigerant. Liquid splashed in the eye can cause frostbit and/or irritation.
4.
Wear appropriate rubber gloves and other clothing whenever there is a potential for splashing liquid refrigerant on your skin. The refrigerant is a solvent for natural oils and will dry out your skin, causing irritation and cracking. Read and follow the information in the material safety data sheet provided by your refrigerant supplier regarding the proper handling of refrigerant.
5.
WARNING Avoid injury! Avoid breathing A/C refrigerant, lubricant vapor or mist. If accidental system discharge occurs, ventilate the work area before resuming service. Failure to comply could result in death or serious injury. W1000A
Never mix R134A with air for leak testing. In general, do not use or mix with pressurized air. Pressurized, air rich mixtures of R134A and air can be flammable when exposed to an ignition source. 6.
Never perform operation other than routine maintenance on your extraction or recycling equipment without first consulting the manufacturer â&#x20AC;&#x2122;s authorized personnel. Removal of fitting and filters can cause refrigerant under pressure to escape. Use the proper safety equipment, including safety goggles.
7.
Never service or maintain extraction or recycling equipment while it is plugged in unless proper service procedures direct you to do so. 47487694-50.200 17/01/2013
50.3 [50.200] / 30
Cab climate control - Air conditioning
8.
Always transfer refrigerant to cylinders or tanks specifically approved for refilling by the U.S. Department of Transportation. The designations “DOT 4BW” or “DOT 4BA” indicate such approval. Use no other container.
9.
Never overfill a refrigerant container. There must be vapor space left in the cylinder to accommodate temperature-indicated changes in pressure and liquid volume. For shop use, SAE recommends filling tanks with liquid to no more than 60 % of their gross weight rating.
10.
Never heat containers to more than 52 °C (126 °F). Even a correctly filled container becomes an explosive hazard if its temperature exceeds 52 °C (126 °F).
11.
Recycling equipment may create sparks or arcs in internal switches or other systems. Because of the fire and explosive hazard that may be present, always use it in location with forced ventilation having at least four air changes per hour.
12.
Extension cords are a known cause of fires and equipment malfunction. Their use is not recommended. If necessary, use the shortest possible extension cord with 14 gauge or larger conductors. If you use service equipment requires a ground circuit (third prong), make sure that the extension cord has a third-prong ground and that the ground circuit is intact. Avoid cords that are worn, frayed, or otherwise damaged.
13.
Perform work in well-ventilated areas. Some refrigerant can accumulate in low areas such as service pits. Breathing concentrated refrigerant vapors could result in asphyxiation or other health hazards, including cardiac arrest.

1.
Check all air conditioning system functions. Make sure the compressor clutch (Y-027) engages when the temperature control switch is turned from OFF to ON position.
2.
If the compressor drive belt is slipping, adjust belt tension.
3.
Make sure the cab air filter is clean and free of obstruction.
4.
Make sure the evaporator fins are not plugged or excessively dirty, causing insufficient air flow across the evaporator core.
5.
Make sure the condenser core is clean and free of obstruction to air flow.
6.
Inspect the heater shutoff valves on the engine block. No coolant should be circulating through the heater core when the shutoff valves are closed.
NOTE: If the compressor clutch (Y-027) fails to engage, it may indicate an electrical problem or a malfunction of the electric drive clutch (Y-027) on the compressor. Review the electrical diagram in this section for proper diagnosis. Refer to section 55 - Electrical â&#x20AC;&#x153;Air conditioning electrical systemsâ&#x20AC;?. If the compressor clutch (Y-027) engages but cuts out prematurely, the system may either be low on refrigerant charge or have a malfunction of the expansion valve causing the low-pressure switch (S-039) and the high-pressure switch (S-040) to operate.

Air conditioning - Leakage test Recharging an air conditioning system that leaks simply allows more refrigerant to escape into the atmosphere and ultimately leaves the system non functioning and in need of additional charging. Therefore, the proper service procedure is to locate and fix any leaks before putting any more refrigerant into the system. If a large amount of refrigerant has leaked out, the system pressure will be too low to identify all but the largest leaks. In this case, partially recharge the system with no more than one pound of refrigerant to check for leaks. NOTICE: â&#x20AC;˘ Any refrigerant introduced into the system for the purpose of finding leaks must also be recovered without releasing it into the atmosphere. â&#x20AC;˘ Always use the same type of refrigerant for checking leaks as was originally installed into the AC system by the manufacturer. â&#x20AC;˘ Never use compressed air to detect system leaks. The introduction of air into the system may create a fire or explosion hazard, may overload the desiccant with moisture, and could contaminate the system with dirt and improper oil. All automotive type air conditioning systems leak to some extent. When servicing them it is important that leakage be minimized. Much of the normal leakage comes from the slow seepage of refrigerant through the flexible hoses. Other common sources of leaks are at joints between the flexible hose and metal tubing or at threaded hose connections. These are usually much larger leaks than the natural seepage through the walls of the hose and are almost always repairable. Research by the EPA has found that leak detection can be difficult, but existing halogen leak detection systems are adequate for the major task of finding and repairing leaks causing complaints. Dye stains are not very satisfactory for finding small leaks. Newer electronic leak detectors may offer even better leak detection capabilities. However, no single method can find every leak. Electronic leak detectors may not detect leaks of all refrigerants. For example, older units designed to detect R12 may not detect R134A. Be sure that the leak detector you use is state-of-the-art and that it is designed to detect the refrigerant in the system you are servicing. Service professionals must be extremely diligent in their work to correct all possible leaks. Diligence is essential to ensure that no small, difficult-to-find leaks go undetected. Before leaving a job, make one last leak check. Catching a leak just after service will save an inconvenient and expensive return visit.

Air conditioning - Filling Refill the air conditioning system using the weight method. The lubricants used in R134A tend to layer onto the walls of the refrigeration system. This layering obscures the view through the sight glass. Visual methods of refilling R134A systems will result in improper system charging. For this reason, we do not recommend the old practice of topping off a partially discharged air conditioning system using the sight glass. The Self-Propelled Windrower uses 2.4 kg (5.3 lb) of R134A refrigerant.

Air conditioning - Recover 1.
Be sure that all service equipment hose lines have shutoff valves or check valves within 30 cm (12 in) of their ends. This will ensure that only minimal quantities of refrigerant escape to the atmosphere when the equipment is disconnected from the air conditioning system, and only small amounts of moisture and other contaminants can enter the system.
2.
Be sure that all equipment, including the connecting hose lines and manifold, are compatible with the refrigerant in the system with which you are going to work, and that your equipment has previously been used only with the refrigerant you are about to service.
3.
Be sure that all shutoff valves are tight before connecting them to the air conditioning system.
NOTICE: Keep shutoff valves closed at all times unless they are connected to a vehicleâ&#x20AC;&#x2122;s air conditioning system, a refrigerant storage container or another piece of service equipment containing the same refrigerant. This prevents refrigerant from escaping into the atmosphere, damaging the environment, contaminating the equipment, and costing you money. 4.

Continue to extract refrigerant until the air conditioning system is under a vacuum and there is no refrigerant remaining in the vehicle system.
7.
Verify that there is no refrigerant remaining in the system by: 1.
Shutting off the extraction unit and observing the system pressure level.
2.
Waiting five minutes and observing the system pressure again. If the system pressure has not risen above atmospheric pressure (0 gauge pressure), all refrigerant has been removed and you may proceed to step 8. If after five minutes, the system pressure reading has risen above atmospheric pressure (0 gauge pressure), the extraction/recovery process must be repeated until the pressure reading remains at or below atmospheric for at least two minutes with the extraction equipment shut off before proceeding to step 8.
8.
Close the shutoff valve in the service lines.
9.
Remove the service lines from the vehicle system. If the recovery equipment has automatic closing shutoff valves, verify that they are operating properly and do not leak.

10.
Determine the amount of lubricant removed from the air conditioning system during the refrigerant extraction process. Replenish the air conditioning system with an equal volume of new, correct lubricant.
11.
The system is now ready for service or repair.
NOTICE: Never use CFC11, R11, CFC12, R12, CFC113, R13 or any other substance to flush an R134A system. To do so would break down the lubricant and cause system corrosion. Use of other flushing solvents may cause other problems. If a vacuum pump does not remove the solvent, it could affect the chemical stability of the refrigerant and lubricant.

Air conditioning - Service instruction Using a Manifold Gauge Set When using a manifold gauge set to diagnose, recharge, or service the windrower air conditioning system: 1.
Be sure that all equipment hose lines are fitted with shutoff valves or check valves within 30 cm (12 in) of their ends and that the valves are closed. This will ensure that only minimal quantities of refrigerants escape to the atmosphere, and that only small amounts of moisture and other contaminants can enter the system.
2.
Be sure that all equipment including the connecting hose lines and manifolds are: â&#x20AC;˘
Compatible with the refrigerant in the air conditioning system;
â&#x20AC;˘
Free of all contaminants;
â&#x20AC;˘
Used only for the same type of refrigerant in the system.
3.
Be certain that all shutoff valves are closed tightly before connecting them to the air conditioning system or charging source.
4.
Connect the manifold gauge set to the unit according to the instructions supplied by the gauge manufacturer.
5.
Perform the desired diagnostic and service operation.
6.
Close the shutoff valves on the service hoses.
7.
Disconnect the hoses from the system.
NOTE: Attach the hoses to recovery or recycling equipment whenever disconnecting the manifold gauge set from the air conditioning system, emptying refrigerant from it, or moving the center hose to another device which cannot accept refrigerant pressure. Remove the refrigerant, lubricant, and contaminants from the hoses.

Air conditioning - Check Refrigerant for Excess Air At times you may question whether or not a container of refrigerant has been recycled. One check which can be done in the shop is to determine if there is excess air mixed in with the refrigerant. This check is a simple comparison of the container pressure with theoretical pressure at a known temperature. If the pressure is equal to or less than a theoretical value of usable purity established for R134A, the container does not have excess air. NOTICE: Using R134A with excess air will result in higher system operating pressures and may cause damage to the air conditioning system. Do this check in the following manner: 1.
Store the container for at least 12 hours at a known temperature of 18.3 °C (65 °F) or higher. The container must not be in direct sunlight or under the influence of any other direct source of heat. Carry out all of the next steps in the same area in which the container is stored, as it is very important that the temperature of the container remain stable.
2.
Attach an appropriate pressure gauge to the container. This pressure gauge should read in increments of 6.9 kPa (1 psi).
3.
Use a calibrated thermometer to measure the air temperature within 10 cm (4 in) of the container surface.
4.
Compare the pressure in the container with the pressure shown for the temperature of the tank for R134A. If the pressure in the container is equal to or less than the pressure in the table, the refrigerant in the container meets the requirements for excess air. If the pressure is greater than shown in the table, you may still be able to use the refrigerant by proceeding to step 5.
5.
If the pressure exceeds that of the table, connect the tank to recovery or recycling equipment in such a way as to allow you to continue to monitor tank pressure.
6.
Bleed a small amount of vapor from the tank into the recovery or recycling equipment until the tank pressure is below that shown in the table for the temperature at which the tank was stored. Close the shutoff valves in the recovery/recycling equipment service hose.
NOTE: This process may cause the temperature of the tank to drop. 7.
Allow the tank temperature to restabilize at the temperature of the storage room by shaking it and allowing it to sit in the same spot for up to another 12 hours.
8.
After making certain that container temperature has again stabilized to room temperature, repeat step 4 above.

50.3 [50.200] / 44
Cab climate control - Air conditioning
If the pressure exceeds that in the table for the storage temperature you measured, the refrigerant in the tank has too much excess air to be used and must be recycled or reclaimed. If the refrigerant being checked has been contaminated with other refrigerant such as R12, the tank pressure may indicate it contains air. If the tank is vented and the pressures still indicates a high reading and you think there is a possibility of the R134A refrigerant being contaminated with R12, the container must be sent to a reclaim facility.

Air conditioning - Storing Containers For Recycled Refrigerant Recycled refrigerant must be stored in DOT CFR Title 49 or UL containers approved for such use. The container must be specifically marked for the refrigerant type you are storing. The use of unmarked containers can lead to mixing of refrigerants and consequent air conditioning system failure. Disposable refrigerant containers should not be used for the storage or recovery of used or recycled refrigerant. Disposable container are the type of container in which virgin refrigerant is often sold. Any container of recycled refrigerant that has been stored or transferred must be checked prior to its use in accordance with the temperature/pressure check described previously in â&#x20AC;&#x153;Checking Refrigerant for Excess Air.â&#x20AC;? New storage tanks must be evacuated to at least 635 mm (25 in) of mercury prior to use. Otherwise, excess air may be introduced to the refrigerant.

Air conditioning - Evacuate Disposal of Empty or Near-Empty Disposable Containers Improper scrapping of a disposable container can release some refrigerant into the atmosphere. This must be avoided by removing any of the remaining contents with a recovery or recycling machine as follows: 1.
Attach the service hose of your recovery or recycling machine to the container.
2.
Open the container valve and the recovery/recycling equipment shutoff valve and evacuate the container just as you would a mobile air conditioning system.
3.
When the maximum stable vacuum has been achieved, close the container valve and the service hoses valve, allowing the vacuum to be in the container.
4.
Mark the container â&#x20AC;&#x153;emptyâ&#x20AC;? and dispose of it properly.

Electrical system - Dynamic description - Header PTO fwd/rev solenoid [YCG667001-] INT, [YCG667001-] NA
Brief Description The PTO forward/reverse solenoid Y-011 (6 cylinder) or PTO forward solenoid Y-30 and PTO reverse solenoid Y-031 (4 cylinder) are some of the output devices associated with the Hydraulic Header System. The solenoids will allow the operator to change the header's direction of spin, by receiving a Pulse Width Modulation (PWM) signal from the universal control module A-001. For additional information concerning the solenoids, refer to Electrical system Component identification Solenoids: Y-001 (Right header flotation solenoid) â&#x20AC;&#x201D; Y-048 (Engine decompression solenoid) (55.000)
Operation Prior to the header forward/reverse operation, the universal control module A-001 will verify the seat switch S-002 is closed, and the park brake switch S-028 is in the OFF position. In addition: In order for the header to rotate in the forward direction the PTO engage switch S-017 should be in the ON position and the header PTO direction switch S-052 is in the FWD position. In order for the header to rotate in the reverse direction the PTO engage switch S-017 should be in the OFF position and the header PTO direction switch S-052 is in the REV position. At key-on, the Ignition Control #2 Relay K-038 will energize and its normally open contact will close. The closed contact will allow current to flow through to the sensors fuse F-014, the PTO engage switch S-017, and then to the universal control module A-001. FORWARD OPERATION When the PTO engage switch S-017 is pull upward to the ON position, a header ON signal is sent to the universal control module A-001. The universal control module A-001 will verify the header PTO direction switch S-052 is in the FWD position. After the PTO engage switch S-017 and the header PTO direction switch S-052 signals are received, the universal control module A-001 will send a PWM signal to PTO forward/reverse solenoid Y-011 (6 cylinder) or PTO forward solenoid Y-30 (4 cylinder). The energized solenoid will open a path for supply oil to flow to the right and left header drives, which in turn will produce header forward rotation. As the header rotates in the forward direction, it pushes the crop material down so the cutting devices can cut as close to the ground as possible. The universal control module A-001 monitors the current flow of solenoid to provide precise control of the solenoid. REVERSE OPERATION When the PTO engage switch S-017 is push downward to the OFF position, a header OFF signal is sent to the universal control module A-001.The universal control module A-001 will verify the header PTO direction switch S-052 is in the REV position. After PTO engage switch S-017 and header PTO direction switch S-052 signals are received, the universal control module A-001 will send a PWM signal to PTO forward/reverse solenoid Y-011 (6 cylinder) or PTO reverse solenoid Y-031 (4 cylinder). The energized solenoids will open a path for supply oil to flow to the right and left header drives, which in turn will produce header reverse rotation. The header will rotate in the reverse direction for 3 s only, to allow any debris to be cleared. The operator must repeat the reverse cycle to repeat the header cleaning. The universal control module A-001 monitors the current flow of solenoid to provide precise control of the solenoid. SPEED The sickle header speed is controlled by the windrower engine speed. To increase or decrease the header speed the operator will increase or decrease the engine speed by using the throttle switch S-071. Increase the header speed by actuating the top side (+) of the throttle switch S-071 or decrease the header speed by actuating the bottom side (-) of the throttle switch S-071. The disc header speed is controlled by using the header speed switch S-013. Increase the header speed by actuating the top side (+) of the header speed switch S-013 or decrease the header speed by actuating the bottom side (-) of the header speed switch S-013. Once universal control module A-001 has received an increase or decrease signal, it monitors the header speed using the header speed sensor B-005. The universal control module A-001 interprets the header speed sensor B-005 signals and controls the output of hydraulic pump by sending the pump a PWM signal. 47487694 17/01/2013

Electrical system - Dynamic description - Deck shift solenoids [YCG667001-] INT, [YCG667001-] NA
Brief Description The Left deck shift solenoid Y-016 and the Right deck shift solenoid Y-017 are some of the output devices associated with the Hydraulic Draper System. These solenoids allow the operator to move the deck from side to side or apart to create center to end windrow delivery. For additional information concerning the deck shift solenoids, refer to Electrical system - Component identification Solenoids: Y-001 (Right header flotation solenoid) â&#x20AC;&#x201D; Y-048 (Engine decompression solenoid) (55.000)
Operation Prior to the deck shift operation, the universal control module A-001 will verify the park brake switch S-028 is in the OFF position and the seat switch S-002 is closed. At key-on, the Ignition Control #2 Relay K-038 will energize and its normally open contact will close. The closed contact will allow current to flow through to the sensors fuse F-014, the PTO engage switch S-017, and then to the universal control module A-001. SHIFT DECK TO THE LEFT NOTE: The draper deck will shift to the center of the windrower when neither the top or bottom side is actuated. To shift the deck to the left, actuate the bottom side of the deck shift switch S-021 and the universal control module A-001 will receive a shift left signal. When the universal control module A-001 has received a shift left signal, the system will energize the left deck shift solenoid Y-016, which in turn will allow the supply oil to flow through the left deck shift motor thereby shifting the deck to the left. SHIFT DECK TO THE RIGHT NOTE: The draper deck will shift to the center of the windrower when neither the top or bottom side is actuated. To shift the deck to the right, actuate the top side of the deck shift switch S-021 and the universal control module A-001 will receive a shift right signal. When the universal control module A-001 has received a shift right signal, the system will energize the right deck shift solenoid Y-017, which in turn will allow the supply oil to flow through the right deck shift motor thereby shifting the deck to the right.

Electrical system - Overview – Calibrations [YCG667001-]
To ensure proper performance of the Windrower, the Propulsion Cylinder, Set Neutral, and Pintle Arm calibrations must be performed after the indicated component replacements or required adjustments. • Prop cylinder – Required after replacing or adjusting any propulsion related components (steering shaft, prop cylinder, prop valve). Calibrates valve “crack points” so that the valve characteristics are known by the software, and also records the B-061a and B-061b voltages when the propulsion shaft is at full forward and full reverse. • Set Neutral – Required after performing a Prop cylinder calibration to record the B-061a and B-061b voltages when the propulsion shaft is at mechanical neutral. It also records the B-025 steering sensor voltage at the same time. Successful completion of a ‘Set Neutral’ calibration will put the machine in an “OK To Start” condition at the next key-on. • Pintle Arm – Necessary after replacing the neutral sensor, or if getting an unintended “steer right” or “steer left” message at start up when the ground drive pumps are known to be at hydraulic neutral. Records the B-025 steering sensor voltage to use as the indication for when the steering is in neutral.

Electrical system - Preliminary test NOTE: This section is only intended as a general guide to using a digital multi-meter. Always refer to the digital multi-meter manufacturer's operators manual for correct operation. 1.
2.
3.
A multi-meter is an electronic measuring device. The different types of measurement that can be made depends upon the make and model of the multi-meter. Most types of multi-meter have the capacity to measure: - Current (A) ac or dc - Resistance (Ί) - Voltage (V) ac or dc - Continuity (Buzz test) More expensive multi-meters have other functions, such as the capacity to measure frequency (Hz) and test diodes.

General Operation: Before proceeding with a test, decide what is going to be measured (Voltage, Current etc.). Rotate the dial until the pointer is within the relevant zone. Within each zone there are different scales. The scale that is selected will represent the maximum value that the multi-meter will read. Always select a scale which is greater than the value that you intend to measure. If you are unsure of the value to be measured, always select the highest scale and then reduce the scale once you have an idea of the measured value.
The closer that the scale is to the measured value, the more accurate the reading will be e.g. If measuring the voltage of a battery with the scale set at 200 V, the display may read 12 V. However, if the scale was set to 20 V the display may read a more accurate reading of 12.27 V.

Measuring Voltage (Volts): Set the range dial to either ac or dc volts. Connect the Black test probe to the “COM" terminal and the Red test probe to the “V/Ω" terminal. Place the test probes across the component to be measured with the circuit complete (closed). Read the value on the multi-meter display.

7
Measuring Current (Amps): Set the range dial to either ac or dc current. When measuring current up to 2 amps, connect the Red test probe to the "A" terminal. When measuring current up to 10 amps, connect the Red test probe to the "10A" terminal. Always connect the Black test probe to the "COM" terminal. When taking measurement of current, always break the circuit and connect the multi meter in series with the circuit. Read the value on the multi-meter display.
NOTE: For protection, multi meters are usually fused at 10 A. A clip-on type ammeter that is rated for high current should be used for electric motor or actuator circuits. 6.
7.
Measuring Resistance (Ohms): Set the range dial to the desired Ω position. Connect the Red test probe to the “V/Ω" terminal. Connect the Black test probe to the “COM" terminal. If the resistance being measured is connected in a circuit, then turn off the power to the circuit and isolate the component from the circuit, if possible. Connect the test probes to the measuring point and read the value on the multi-meter display.
Continuity (Buzzer) test: Set the range dial to the “Buzz" position. Connect the Red test probe to the “V/Ω" terminal. Connect the Black test probe to the “COM" terminal. Connect the test probes to the measuring point. In general, if the resistance is less than 50 ohms then the buzzer will sound, indicating continuity.
NOTE: Buzzers on different multi meters will sound at different ohmic values, depending on the quality of the meter.

Use of the "Buzz" position for continuity tests can often be misleading. For example, when checking a corroded frame ground point. A poor quality multi meter may buzz at 150 ohms, indicating continuity and no problem. When using a higher quality multi meter for the same test, it would not buzz due to the high resistance. When carrying out such tests, always check the value of resistance as well as listening out for the buzz. A good connection gives low resistance. A bad connection gives high resistance.

Diode Checking (Bias voltage): Set the range dial to the diode position. Connect the Red test probe to the “V/Ω" terminal. Connect the Black test probe to the “COM" terminal. Place the test probes across the diode. Black test probe connected to the Cathode side and Red test probe connected to the Anode side. The display should show the bias voltage of the diode.
NOTE: Isolate the diode from the circuit, before testing. Different multi-meters provide differing bias voltages and currents, readings may vary between multi-meters, check the manual provided with the multi-meter to determine the expected value. 10.
SUMMARY: When measuring Voltage (V): Connect across the component with the circuit closed. Current (A): Connect in series with the circuit. Circuit closed. Resistance (Ω): Connect across the component with the circuit open. Continuity (Buzz): Connect the meter across the component with the circuit open. (Always check the value of resistance as well.) Diodes (Diode checking) Connect across the component with the circuit open.

Higher resistances usually indicate circuit paths through modules, and that an additional connector needs to be disconnected to perform the test. More than 100k ohms indicates that the circuit is free of shorts to ground.
NOTE: All of the output and many of the input devices used in the electrical / electronic system use a reference or chassis ground as a functional part of the control system. Therefore, it is important to remove this intended circuit ground before testing for a "Short to Ground"

Use the black lead (2) to make contact with the connector pin at the other end of the circuit. Avoid contact with other pins in the connector and the connector case, if it is metal.
NOTE: Testing continuity from one connector to another is often not possible given the distance between the connectors. The alternate method used in this service manual requires the use of a jumper wire. Attach the jumper wire between the specified pin in one of the connectors and chassis (frame) ground. Use the red lead of the multi-meter to touch the specified pin of the other connector and touch the black lead to chassis (frame) ground. Using chassis (frame) ground as an integral part of the continuity test requires good electrical contact with the metal frame (chassis). Paint and contaminants serve as insulators and reduce the effectiveness of the electrical connection. If possible use frame (chassis) ground points already established for the black lead and one end of the jumper wire.

Fuel injection system - Dynamic description - Fuel pump high pressure solenoid [YCG667001-] INT, [YCG667001-] NA
Brief Description The High pressure fuel pump solenoid Y-039 is one of the output devices associated with the fuel system. The solenoid controls the supply oil that flows to the high pressure pump, when it receives a Pulse Width Modulation (PWM) signal from the Engine control module A-003. For additional information concerning the solenoids, refer to Electrical system - Component identification Solenoids: Y-001 (Right header flotation solenoid) â&#x20AC;&#x201D; Y-048 (Engine decompression solenoid) (55.000)
Operation Prior to fuel system operation, the universal control module A-001 will verify the seat switch S-002 is closed and the park brake switch S-028 is in the ON position. At key-on and when the park brake switch S-028 is in the ON position, the starter motor M-008 will energize and its normally open contact will close. The closed contact will allow current to flow through to the engine control module fuse F-033, which will complete the engine control module 12 V circuit. After starting the windrower with the park brake switch S-028 in the ON position, the engine control module A-003 will began to monitor the fuel temperature, fuel pressure, and the amount of water in the fuel. The H2O in fuel switch S-088 detects if water is present in the fuel and reports to the engine control module A-003. The main component of the fuel system is the volatility level and the fuel pressure and fuel temperature dictates that level. The volatility level is monitored by the fuel pressure & temperature sensor B-008. The fuel pressure & temperature sensor B-008 has a two variable resistors. One of the resistors will monitor the fuel pressure and the other resistor will monitor the fuel temperature. The data collected will be reported to the engine control module A-003. NOTE: The correct fuel temperature has to be maintain so the fuel can be easily vaporizes. And the fuel pressure has to be high enough to atomizes the fuel. In the case when the fuel pressure is too low, the engine control module A-003 will energize the high pressure fuel pump solenoid Y-039. The energized high pressure fuel pump solenoid Y-039 will open a path for the supply oil to flow to the high pressure pump. As the supply oil flows to the pump, the fuel pressure will increase for proper atomization. The fuel system will then route the high pressure fuel to the fuel rail, where it is stored until the engine control module A-003 energizes one of the engine's fuel injectors. Just before the high pressure fuel enters the fuel rail, the engine control module A-003 will use the rail pressure sensor B-015 to monitor the pressure of the fuel. In addition, the engine control module will use the fuel level sensor R-001 to monitor the fuel level in the fuel tank. As the fuel level rises or lowers, the variable resistance of the sensor changes and those changes are reported the engine control module A-003. The engine control module A-003 will display the appropriate fuel level on the operator gauge.

Brief Description The Injector Cylinders 1-6 Y-040 through Y-045 are some of the output devices associated with the fuel system. These solenoids deliver an accurate amount of fuel to each cylinder, when it receives a Pulse Width Modulation (PWM) signal from the Engine control module A-003. For additional information concerning the fuel injector solenoids, refer to Electrical system - Component identification Solenoids: Y-001 (Right header flotation solenoid) â&#x20AC;&#x201D; Y-048 (Engine decompression solenoid) (55.000)
Operation Prior to fuel injection operation, the universal control module A-001 will verify the seat switch S-002 is closed and the park brake switch S-028 is in the ON position. At key-on and when the park brake switch S-028 is in the ON position, the starter motor M-008 will energize and its normally open contact will close. The closed contact will allow current to flow through to the engine control module fuse F-033 and the engine control module A-003 12 V circuit is complete. When the windrower engine is running the operator can increase or decrease the engine speed by using the throttle switch S-071. The engine speed will increase by actuating the top side (+) of the throttle switch S-071 or decrease by actuating the bottom side (-) of the throttle switch S-071. The universal control module A-001 will use the engine speed to calculate the amount of air entering the windrower and sends that data to the engine control module A-003, using the CAN lines. The engine control module A-003 will use that data to adjust the amount fuel to be delivered to each cylinders. When the engine control module A-003 has determine which injector to fire, it will energize the injector's solenoid. High pressurized fuel will began to flow through the valve and squirt out through the nozzle into the cylinder. For additional information concerning high pressure fuel, refer to Fuel injection system - Dynamic description - Fuel pump high pressure solenoid (55.010) . The engine control module A-003 will also use data from the coolant temperature sensor B-014, the camshaft speed sensor B-012, and the crankshaft speed sensor B-011. The coolant temperature sensor B-014 is used to monitor the engine temperature and to calculate the proper fuel ratio. The camshaft speed sensor B-012 is used to monitor the camshaft position to determine which injector to fire. Lastly, the crankshaft speed sensor B-011 is used to monitor the crankshaft position to determine which injector to fire.

Brief Description The Blow by 3-way solenoid Y-046 is one of the output devices associated with the engine ventilation system. The solenoid will re-route the blow-by gases to the engine's intake system, when it receives a Pulse Width Modulation (PWM) signal from the Engine Control Module A-003. For additional information concerning the blow by solenoid, refer to Electrical system - Component identification Solenoids: Y-001 (Right header flotation solenoid) â&#x20AC;&#x201D; Y-048 (Engine decompression solenoid) (55.000)
Operation Prior to blow-by operation, the universal control module A-001 will verify the seat switch S-002 is closed and the park brake switch S-028 is in the ON position. At key-on and when the park brake switch S-028 is in the ON position, the starter motor M-008 will energize and its normally open contact will close. The closed contact will allow current to flow through to the engine control module fuse F-033 and the engine control module A-003 12 V circuit is complete. Once the engine is running, the de-energized blow by 3-way solenoid Y-046 will began to monitor the pressure in the crankcase. If the crankcase pressure exceeds the blow by 3-way solenoid Y-046 pressure settings, the engine control module A-003 will energize the solenoid. The energized blow by 3-way solenoid Y-046 will open a path for combustion gases to flow back to the intake manifold. Before the combustion gases are release back into the intake manifold, the blow by 3-way solenoid Y-046 will allow a small amount of fresh air from the intake stream to mix in with the gases. The mixing of the two gases will dilute the combustion gas.

At key-on and when the park brake switch S-028 is in the ON position, the starter motor M-008 will energize and its normally open contact will close. The closed contact will allow current to flow through to the engine control module fuse F-033 and the engine control module A-003 12 V circuit is complete. A pressure difference between the intake manifold and the exhaust manifold is required for the EGR system to work properly. Once the engine is running, the variable turbine geometry actuator sensor B-017 will start creating a pressure difference between the exhaust manifold and the intake manifold. The engine control module A-003 will begin to monitor the exhaust and intake pressure differences by using the pressure EGR valve sensor B-010. The pressure EGR valve sensor B-010 will use the difference data to determine how much exhaust gas is flowing through the EGR system. The engine control module A-003 will use that data to instruct the EGR actuator sensor B-016 on how much vacuum pressure should be used to redirect the exhaust gas to the intake manifold through the EGR bypass solenoid Y-047. After the intake and exhaust pressure differences has been calculated and the EGR actuator sensor B-016 knows how much vacuum pressure to allow, then the engine control module A-003 will energize the EGR bypass solenoid Y-047. The energized solenoid will begin to re-circulate the engine's exhaust gases into the intake manifold. In addition, the engine control module A-003 will use the exhaust gas pressure sensor B-009 to monitor the exhaust gas flowing through the EGR bypass solenoid Y-047.

Brief Description The Engine decompression solenoid Y-048 is one of the output devices associated with the engine drive system. The solenoid provides the windrower with an alternate method for braking, by receiving a Pulse Width Modulation (PWM) signal from the Engine Control Module A-003. For additional information concerning the solenoid, refer to Electrical system - Component identification Solenoids: Y-001 (Right header flotation solenoid) â&#x20AC;&#x201D; Y-048 (Engine decompression solenoid) (55.000)
Operation Prior to engine decompression operation, the universal control module A-001 will verify the seat switch S-002 is closed and the park brake switch S-028 is in the ON position. At key-on and when the park brake switch S-028 is in the ON position, the starter motor M-008 will energize and its normally open contact will close. The closed contact will allow current to flow through to the engine control module fuse F-033 and the engine control module A-003 12 V circuit is complete. In order for the windrower to be driven in the forward or reverse direction, the operator must move the multifunction handle (MFH) S-49 NH/ S-51 CIH from the neutral position. The windrower's ground speed will increase, as the MFH is moved further away from the neutral position. And the ground speed will decrease as the MFH is moved closer to the neutral position. As the windrower speed decrease the universal control module A-001 will send the engine speed data to the engine control module A-003. The engine control module A-003 will energize the engine decompression solenoid Y-048. The energized engine decompression solenoid Y-048 will allow compressed air to be release through the exhaust manifold during the end of the intake cycle, which in turn will slow down the windrower.

Electrical systems - Hydrostatic drive control system
Hydrostatic drive control system - Dynamic description - Propulsion fwd/rev solenoids [YCG667001-] INT, [YCG667001-] NA
Brief Description The Propulsion forward solenoid Y-014 and the Propulsion reverse solenoid Y-015 are some of the output devices associated with the Hydrostatic Propulsion System. When energized, these solenoids will allow the operator to drive the windrower in the forward or reverse direction. Each solenoid is energized when a Pulse Width Modulation PWM signal is received from the Universal control module A-001. For additional information concerning the propulsion solenoids, refer to Electrical system - Component identification Solenoids: Y-001 (Right header flotation solenoid) â&#x20AC;&#x201D; Y-048 (Engine decompression solenoid) (55.000) and/or propulsion relays Electrical system - Component identification Relays: K-004 (Accessory control relay) â&#x20AC;&#x201D; K-076 (Ignition control #1 relay) (55.000).
Operation Prior to the windrower forward/reverse operation, the universal control module A-001 will verify the park brake switch S-028 is in the OFF position, the seat switch S-002 is closed and the PTO engage switch S-017 is in the ON position. In order for the windrower to be driven in the forward or reverse direction, the operator must move the Multifunction Handle (MFH) S-049 NH/ S-051 CIH from the neutral position. The windrower's ground speed will increase, as the MFH is moved further away from the neutral position. And the ground speed will decrease as the MFH is moved closer to the neutral position. For additional information concerning ground speed, refer to Hydrostatic drive control system - Dynamic description - Ground speed solenoid (55.019) At key-on, the Ignition Control #2 Relay K-038 will energize and its normally open contact will close. The closed contact will allow current to flow through to the sensors fuse F-014, the PTO engage switch S-017, and then to the universal control module A-001. When the operator as engaged the MFH, the universal control module A-001 will instruct the MFH position sensor B-054 to measure the angular position of MFH and the propulsion cylinder position sensor B-061 to measure the position of the hydraulic cylinder. The universal control module A-001 will gather the angular position data and the hydraulic cylinder position data, and determine the cylinder position error. The universal control module A-001 will use the cylinder position error to determine what direction and how far to move the hydraulic cylinder, which in turn will move the windrower in the forward or reverse direction. The pintle arm position sensor B-025 is used by the universal control module A-001 to determine the position the pintle arms. FORWARD OPERATION When the MFH is moved forward, the MFH switch S-003 will close and deliver 12 V to the propulsion enable relay K-035. The propulsion enable relay K-035 will energize and its normally open contact will close. The closed contact will allow a propulsion signal to be delivered to the universal control module A-001. When the universal control module A-001 has received the propulsion signal, it will gather the cylinder position error data and energize the propulsion forward solenoid Y-014. The energized propulsion forward solenoid Y-014 will open a path for the supply oil to flow through the left and right hydraulic pumps and then to the wheel motors. This action will result in forward movement. REVERSE OPERATION When the MFH is moved reverse, the MFH switch S-003 will close and deliver 12 V to the propulsion enable relay K-035. The propulsion enable relay K-035 will energize and its normally open contact will close. The closed contact will allow a propulsion signal to be delivered to the universal control module A-001. When the universal control module A-001 has received the propulsion signal, it will gather the cylinder position error data and energize the propulsion reverse solenoid Y-015. The energized propulsion reverse solenoid Y-015 will open a path for the supply oil to flow through the left and right hydraulic pumps and then to the wheel motors. This action will result in reverse movement.

Hydrostatic drive control system - Dynamic description - Ground speed solenoid [YCG667001-] INT, [YCG667001-] NA
Brief Description The Ground speed high solenoid Y-023 is one of the output devices associated with the ground drive operation. The solenoid will allow the operator to adjust the speed of the windrower. For additional information concerning the ground speed solenoid, refer to Electrical system - Component identification Solenoids: Y-001 (Right header flotation solenoid) â&#x20AC;&#x201D; Y-048 (Engine decompression solenoid) (55.000)
Operation Prior to the ground speed operation, the universal control module A-001 will verify the park brake switch S-028 is in the OFF position, the seat switch S-002 is closed and the PTO engage switch S-017 is in the ON position. At key-on, the Ignition Control #2 Relay K-038 will energize and its normally open contact will close. The closed contact will allow current to flow through to the sensors fuse F-014, the PTO engage switch S-017, and then to the universal control module A-001. HIGH SPEED When the top side of the ground speed range switch S-100 is actuated, the universal control module will send a 12 V PWM signal to the ground speed high solenoid Y-023. The energized ground speed high solenoid Y-023 will open a path for the supply oil to flow through the ground drive cylinders, then to the left and right ground drive motors. The ground drive motors will mechanically shift from the low-speed range to the high-speed range of 900 - 2250 RPM. HIGH SPEED When the bottom side of the ground speed range switch S-100 is actuated, the ground speed high solenoid Y-023 will de-energized and the supply oil will flow to the tank reservoir as the ground drive cylinders return to the low-speed range of 0 - 900 RPM. During the ground speed operation, the universal control module A-001 will begin to monitor the speed of the windrower relative to the ground, using the left ground speed sensor B-001 and the right ground speed sensor B-002. The left ground speed sensor B-001 and right ground speed sensor B-002 (located on the brake housing) will detect the brake hub notched disk as it rotates with the brakes' splined hub. Each time the sensor senses the notched disk, it will send a electrical signal to the universal control module A-001. The universal control module A-001 will convert the electrical signals into real time ground speed. This real time ground speed will be displayed in kph or mph on the display monitor.

Brake control solenoids - Dynamic description [YCG667001-] INT, [YCG667001-] NA
Brief Description The Brake valve release solenoid Y-028 is one of the output devices associated with the ground drive operation. The solenoid will allow the operator to enable the modular braking system, when it receives 12 V from the park brake latch relay K-053. For additional information concerning the brake solenoid, refer to Electrical system - Component identification Solenoids: Y-001 (Right header flotation solenoid) — Y-048 (Engine decompression solenoid) (55.000) and/or the information concerning park brake relays refer to Electrical system - Component identification Relays: K-004 (Accessory control relay) — K-076 (Ignition control #1 relay) (55.000)
Operation Prior to parking brake operation, the universal control module A-001 will verify the seat switch S-002 is closed and the park brake switch S-028 is in the ON position. At key-on, the Ignition Control #2 Relay K-038 will energize and its normally open contact will close. The closed contact will allow current to flow through to the controls fuse F-12 and then the park brake latch relay K-053. PARKING BRAKE ENGAGED When the park brake switch S-028 is in the ON position, the universal control module A-001 receives a parking brake engaged signal and 12 V is delivered to the start interlock relay K-048. The brake valve release solenoid Y-028 will remain de-energized, which will allow the supply oil to flow from the parking brake cylinders to the tank reservoir as the parking brakes are applied. PARKING BRAKE DISENGAGED When the park brake switch S-028 is in the OFF position, the universal control module A-001 receives a parking brake disenaged signal and 12 V is delivered to the park brake latch relay K-053. When the universal control module A-001 has received the parking brake signal, it will designate pin 85 of the park brake latch relay K-053 as ground. The park brake latch relay K-053 will energize and its normally open contact will close. The closed contact will energize the brake valve release solenoid Y-028. The energized brake valve release solenoid Y-028 will open a path for the supply oil to flow to the parking brake cylinders. The parking brake cylinders will extend within the modular brakes which will release the spring-applied brakes.

The display provides the operator with information about the system’s performance. • It provides the desired cab temperature reading selected by the operator. The display reading may be in Fahrenheit or Celsius. To make the change, there is a ground wire located under the left rear corner of the cab at the main ground boss. Attaching the wire to the ground provides for Celsius readings. • It illuminates an icon “A”, when the system is automatically controlling fan speed. • When the “A” is not illuminated the blower motor speed MUST be manually controlled and “Auto” mode will only control the water valve and compressor, while trying to maintain the set temperature. • It illuminates an icon of a windshield when the system is in the Defog mode. • It illuminates a snowflake when the air conditioning compressor is running. • It illuminates an icon of a book when the system is not operating correctly. Along with the book icon a fault code will also be displayed to assist the technician in making the correct repairs. The range for ATC is from a setpoint of 16 °C (61 °F)to 31.5 °C (89 °F). The setpoint of 15.5 °C (60 °F)or 32 °C (90 °F) will be displayed and the “A” icon on the display will be on when the system is in maximum mode.

Blower Speed Control, (3) The blower speed control gives the operator control over the speed of the blower motor. Turning the blower control clockwise will increase the speed of the blower, producing more airflow out of the cab vents, turning the control counter clockwise will reduce the air flow. If the ATC control button has been pressed, the blower speed control position will have NO effect over the blower’s speed. The ATC controller will increase or decrease the blower motor speed as needed to maintain the desired cab temperature. If the blower speed control is adjusted, the controller will release the automatic control over the blower motor speed. The blower motor will only operate in the manual mode if the “A” is NOT displayed. The ATC control button must be toggled OFF and back ON to reset the automatic blower motor operating mode. The automatic temperature control will always be operating whether the “A” is displayed or not. The blower control is a potentiometer rated at 10K ± 10 % ohms. When operating in the Auto Climate or Defog mode, the blower will make a speed increase for every 2 °F difference there is between the temperature set point and the actual cab temperature sensed by the cab temperature sensor. If the outlet sensor senses that the outlet temperature is more than 5°F (3°C) cooler than the cab temperature, and system is calling for heat, the blower speed will not be increased until the outlet temperature has increased. Fan speed is also limited if cab temperature is more than 4°F (2°C) cooler than the set temperature.

Defog Control, (4) Once the operator has activated the ATC control, the mode button is pressed to toggle the Defog on and off. The digital display window will be illuminated with the symbol displayed when the Defog is on. The system will run the A/C compressor full time and warm the air to defog the windows and the display will be illuminated.
ATC Control, (5) The operator selects ATC Control by pressing the left hand button one time, the digital display window will be illuminated. When illuminated the mode of operation will be displayed along with the desired temperature. The button toggles between two modes: • “O” = OFF, the cab blower motor may be run, but the air will not be conditioned and the display will NOT be illuminated. • “A” = Auto, the system will warm or cool the air as needed, and control the blower speed to maintain the cab temperature and the display will be illuminated.

Electrical systems - Heating, Ventilation, and Air-Conditioning (HVAC) control system
Cab heater blower unit - Dynamic description [YCG667001-] INT, [YCG667001-] NA
Brief Description The Blower motor M-002 and the ATC water valve motor M-015 are some of the output devices associated with the HVAC system. These motors control the speed of the blower motor and amount of water that will flow through the evaporator coils, when they receives 12 V from the HVAC Relay K-013. For additional information concerning the HVAC motors, refer to Electrical system - Component identification Motors: M-001 (Reel speed motor) â&#x20AC;&#x201D; M-018 (Windrow shields motor) (55.000) and/or for information concerning the HVAC relays refer to Electrical system Component identification Relays: K-004 (Accessory control relay) â&#x20AC;&#x201D; K-076 (Ignition control #1 relay) (55.000).
Operation Prior to the HVAC system operation, the universal control module A-001 will verify the engine is running and the automatic & manual HVAC module A-012 internal A/C switch is closed. At key-on, the HVAC Relay K-013 will energize and its normally open contact will close. The closed contact will allow current to flow to the blower motor M-002 and the ATC water valve motor M-015. After the windrower engine is running and the automatic & manual HVAC module A-012 internal A/C ON/OFF switch is closed, the blower motor M-002 will receive 12 V from the HVAC Relay K-013. The main function of blower motor M-002 is to move outside air through the system filters, over the evaporator core and into the cab. The blower motor M-002 speed is controlled by a 3 speed switch, located on the left side of the HVAC module. The blower speed is increase when the blower speed switch is turned clockwise and decrease when switch is turned counter-clockwise. With the Automatic Temperature Control (ATC) option, the automatic & manual HVAC module A-012 will monitor the outlet temperature using the outlet temperature sensor B-004 and the cab temperature using the cab temperature sensor B-023. And the system will only increase the blower speed when the outlet temperature is more than the cab temperature. The ATC water valve motor M-015 has two functions: one is to receive the blower motor M-002 speed signal from the automatic & manual HVAC module A-012 and adjust blower motor M-002 speed according. Secondly, the ATC water valve motor M-015 will receive a heat signal from the automatic & manual HVAC module A-012 and then adjust the amount of coolant that will flow through the evaporator core.

Engine starter Starter solenoid - Dynamic description - Starter motor [YCG667001-] INT, [YCG667001-] NA
Brief Description The Starter motor M-008 is an output device associated with the starter system. The solenoid/motor assembly main function is to provide the engine its require RPM to start the engine ignition process. The solenoid/motor assembly is able to achieve its purpose when it receives 12 V from the Starter relay K-005. For additional information concerning the starter motor, refer to Electrical system - Component identification Motors: M-001 (Reel speed motor) — M-018 (Windrow shields motor) (55.000) and/or information concerning the starter relays refer to Electrical system - Component identification Relays: K-004 (Accessory control relay) — K-076 (Ignition control #1 relay) (55.000).
Operation Prior to starter operation, the universal control module A-001 will verify the seat switch S-002 is closed and the park brake switch S-028 is in the ON position. When the engine is running and the park brake switch S-028 is engaged, the universal control module A-001 will energized the start interlock relay K-048. When start interlock relay K-048 is energized and its normally open contact will close. The closed contact will energize the starter relay K-005, which in turn will start the engine ignition process. IGNITION KEY IN START POSITION Before starting the windrower engine, the operator should: (1) engage the park brake switch S-028, (2) put the steering wheel in the neutral position, and (3) put the Multifunction Handle S-049 (NH)/ S-051 (CIH) in the neutral position. Once the engine is running, the starter motor M-008 solenoid will energize when it receives 12 V from starter relay K-005. The starter motor M-008 will energize and its normally open contact will close. The closed contact will deliver 12 V to starter motor M-008 motor. IGNITION KEY IN IGN POSITION The starter motor M-008 will start to spin, as the bendix extends into the flywheel. The flywheel will began to the spin the engine and once the engine is running the ignition key is released. When the ignition key is released, the starter motor M-008 will no longer be energized.

Cab controls - Dynamic description - Seat suspension motor [YCG667001-] INT, [YCG667001-] NA
Brief Description The Seat suspension pump motor M-003 is one of the output devices associated with the operator's seat system. The motor will allow the operator to adjust the seat position, when it receives 12 Vfrom the Accessory control relay K-004. For additional information concerning the seat suspension motor, refer to Electrical system - Component identification Motors: M-001 (Reel speed motor) — M-018 (Windrow shields motor) (55.000) and/or for information concerning relays refer to Electrical system - Component identification Relays: K-004 (Accessory control relay) — K-076 (Ignition control #1 relay) (55.000).
Operation Prior to the seat suspension operation, the universal control module A-001 will verify the seat switch S-002 is closed and the key switch S-004 is in the ACC position. At key-on, the accessory control relay K-004 will energize and its normally open contact will close. The closed contact will allow current to flow through to the seat suspension fuse F-020. RAISE SEAT When the top side of the seat suspension switch/valve (located on the left armrest) is actuated and held, the seat suspension switch/valve internal switch will deliver 12 V to the seat suspension pump motor M-003. The energized seat suspension pump motor M-003 will began to supply air to the seat's internal air spring, which in turn will raise the seat. The seat will continue to raise until the seat suspension switch/valve is released. LOWER SEAT When the bottom side of the seat suspension switch/valve is actuated and held, the seat suspension switch/valve internal valve will open and allow the supplied air to flow from the seat's internal air spring, which in turn will lower the seat. The seat will continue to lower until the seat suspension switch/valve is released

Brief Description The Windshield wiper motor M-004 and the Windshield washer pump motor M-005 are the output devices associated with the windshield washer/wiper system. These motors will allow the operator to adjust the windshield wiper speed and to apply windshield washer fluid, when they receive a 12 V from the Accessory control relay K-004. For additional information concerning the wiper/washer motors, refer to Electrical system - Component identification Motors: M-001 (Reel speed motor) — M-018 (Windrow shields motor) (55.000) and/or for information concerning wiper/ washer relays refer to Electrical system - Component identification Relays: K-004 (Accessory control relay) — K-076 (Ignition control #1 relay) (55.000).
Operation Prior to the windshield wiper/washer operation, the universal control module A-001 will verify the seat switch S-002 is closed and the key switch S-004 is in the ACC position. At key-on, the accessory control relay K-004 will energize and its normally open contact will close. The closed contact will allow current to flow through to the windshield wiper fuse F-015 and the windshield wash & mirrors fuse F-019. WINDSHIELD WASHER When the windshield washer pump switch S-036 is actuated and released, 12 V is delivered to the windshield washer pump motor M-005. The energized windshield washer pump motor M-005 will began to pump windshield washer fluid. WINDSHIELD WIPER When the windshield wiper switch S-035 is actuated and released for the first time, 12 V is delivered to the windshield wiper motor M-004 at its wiper hi-speed position. The second time the windshield wiper switch S-035 is actuated the windshield wiper motor M-004 will receive 12 V at its wiper low-speed position. And actuating the windshield wiper switch S-035 for the third time will send 12 V to the windshield wiper motor M-004 wiper OFF position.

Brief Description The Draper reel height solenoid Y-033 and the Draper unload solenoid Y-038 are some of the output devices associated with the Hydraulic Draper System. The solenoids will allow the operator to lift the draper reel, when it receives a 12 V Pulse Width Modulation (PWM) signal from the universal control module A-001.
Operation Prior to the reel lift operation, the universal control module A-001 will verify the engine is running, the park brake switch S-028 is in the OFF position, the seat switch S-002 is closed and the PTO engage switch S-017 is in the ON position. At key-on, the Ignition Control #2 Relay K-038 will energize and its normally open contact will close. The closed contact will allow current to flow through to the sensors fuse F-014, the PTO engage switch S-017, and then to the universal control module A-001 RAISE OPERATION When the multi-function handle (MFH) reel raise switch is actuated, it will send a reel raise signal to the universal control module A-001. The universal control module A-001 will first energize the draper unload solenoid Y-038. The energized draper unload solenoid Y-038 will allow supply oil to flow from the supply port to the draper reel height solenoid Y-033. As supply oil begans to flow, the universal control module A-001 will energize the draper reel height solenoid Y-033 and the draper reel will raise. LOWER OPERATION When the multi-function handle (MFH) reel lower switch is actuated, it will send a reel lower signal to the universal control module A-001. The draper unload solenoid Y-038 will remain de-energize and will allow supply oil to flow from the draper reel height solenoid Y-033 to the tank reservoir. As supply oil begans to flow, the universal control module A-001 will energize the draper reel height solenoid Y-033 and the draper reel will lower.

Reel speed synchronization system - Dynamic description Electrical [YCG667001-] INT, [YCG667001-] NA
Brief Description The Reel speed solenoid Y-012 (Draper Header), the Sickle reel speed solenoid Y-029 (non-Draper Header), the Reel speed motor M-001 are some of the output devices associated with the reel speed system. The solenoids will allow the operator to increase or decrease the reel speed, when it receives a Pulse Width Modulation PWM signal from the Universal control module A-001. For additional information concerning the reel speed solenoids, refer to Electrical system - Component identification Solenoids: Y-001 (Right header flotation solenoid) â&#x20AC;&#x201D; Y-048 (Engine decompression solenoid) (55.000) and/or reel speed motor Electrical system - Component identification Motors: M-001 (Reel speed motor) â&#x20AC;&#x201D; M-018 (Windrow shields motor) (55.000).
Operation Prior to the reel speed operation, the universal control module A-001 will verify the park brake switch S-028 is in the OFF position, the seat switch S-002 is closed and the PTO engage switch S-017 is in the ON position. At key-on, the Ignition Control #2 Relay K-038 will energize and its normally open contact will close. The closed contact will allow current to flow through to the sensors fuse F-014, the PTO engage switch S-017, and then to the universal control module A-001 AUTO VERSUS MANUAL When the top side (auto) of the reel mode switch S-027 is actuated, the universal control module A-001 will receive an auto signal. The system will then energize reel speed solenoid Y-012 or sickle reel speed solenoid Y-029, which will allow pressure to flow through the hydraulic pump and maintain a relative speed between the forward speed using the reel speed motor M-001. When the bottom side (manual) of the reel mode switch S-027 is actuated, the universal control module A-001 will receive the manual signal. At this point, the operator can increase or decrease the reel speed by actuating the top side (increase) or the bottom side (decrease) of the multi-function handle (MFH) reel speed switch, which in turn will control the reel speed motor M-001. INCREASE SPEED To increase the reel speed, the operator should actuate the top side of the multi-function handle (MFH) reel speed switch. A reel speed increase signal will be sent to the universal control module A-001. The universal control module A-001 will then designate pin E1 of the reel speed increase relay K-019 and pin 1 of the reel speed motor M-001 as ground. The reel speed increase relay K-019 will energize and its normally open contact will close. The closed contact will deliver 12 V to the reel speed motor M-001 and the reel speed will began to increase. DECREASE SPEED To decrease the reel speed, the operator should actuate the bottom side of the multi-function handle (MFH) reel speed switch. A reel speed decrease signal will be sent to the universal control module A-001. The universal control module A-001 will then designate pin B1 of the reel speed decrease relay K-020 and pin 2 of the reel speed motor M-001 as ground. The reel speed decrease relay K-020 will energize and its normally open contact will close. The closed contact will deliver 12 V to the reel speed motor M-001 and the reel speed will began to decrease.

Reel speed synchronization system - Dynamic description - Reel dump solenoid [YCG667001-] INT, [YCG667001-] NA
Brief Description The Reel dump solenoid Y-035 is one of the output devices associated with the reel operation. The main function of the reel dump solenoid Y-035 is to provide hydraulic pressure to the Reel speed solenoid Y-029. The solenoid is energized when it receives a Pulse Width Modulation (PWM) signal from the universal control module A-001. For additional information concerning the reel dump solenoid, refer to Electrical system - Component identification Solenoids: Y-001 (Right header flotation solenoid) â&#x20AC;&#x201D; Y-048 (Engine decompression solenoid) (55.000).
Operation Prior to the reel dump operation, the universal control module A-001 will verify the park brake switch S-028 is in the OFF position, the seat switch S-002 is closed and the PTO engage switch S-017 is in the ON position. At key-on, the Ignition Control #2 Relay K-038 will energize and its normally open contact will close. The closed contact will allow current to flow through to the sensors fuse F-014, the PTO engage switch S-017, and then to the universal control module A-001 When the top side (auto) of the reel mode switch S-027 is actuated, the universal control module A-001 will receive a auto signal. The system will then energize the reel speed solenoid Y-029, which will allow pressure to flow through the hydraulic pump and maintain relative speed between the forward speed using the reel speed motor M-001. The reel speed solenoid Y-029 does not produce hydraulic pressure, it only regulates the pressure being deliver. And because of this, the reel speed solenoid Y-029 requires a component to produce the hydraulic pressure. The reel dump solenoid Y-035 will began to build the require pressure needed to be deliver to the reel speed motor M-001. In the Reel dump solenoid Y-035 de-energized state, it will allow a bi-directional pressure flow, which will allow pressure to flow back to the reservoir tank. When the reel speed solenoid Y-029 is energized by universal control module A-001, the reel dump solenoid Y-035 is also energized and will be began to block pressure flow.

Merger electrical control system - Dynamic description - Merger ON/OFF solenoid [YCG667001-] INT, [YCG667001-] NA
Brief Description The Merger ON/OFF solenoid Y-034 is one of the output devices associated with the merger operation. The solenoid will allow the operator to turn the merger operation on or off, when it receives a 12 V Pulse Width Modulation (PWM) signal from the Universal control module A-001. For additional information concerning the merger solenoids, refer to Electrical system - Component identification Solenoids: Y-001 (Right header flotation solenoid) â&#x20AC;&#x201D; Y-048 (Engine decompression solenoid) (55.000)
Operation Prior to the merger ON/OFF operation, the universal control module A-001 will verify the park brake switch S-028 is in the OFF position, the seat switch S-002 is closed and the PTO engage switch S-017 is in the ON position. At key-on, the Ignition Control #2 Relay K-038 will energize and its normally open contact will close. The closed contact will allow current to flow through to the sensors fuse F-014, the PTO engage switch S-017, and then to the universal control module A-001 MERGER ON When the top side of the merger ON/OFF switch S-031 is actuated, it will send the universal control module A-001 a ON signal. As long as the merger ON/OFF switch S-031 is the ON position the merger ON/OFF solenoid Y-034 will remain de-energized. The de-energized merger ON/OFF solenoid Y-034 will allow the supply oil to flow from the merger control valves to the tank reservoir. MERGER OFF When the bottom side of the merger ON/OFF switch S-031 is actuated, it will terminate the 12 V position signal to the universal control module A-001. At this point the universal control module A-001 will energize the merger ON/OFF solenoid Y-034. When the energized merger ON/OFF solenoid Y-034 will block the supply oil from flowing to the merger control valves, thus turning OFF the merger.

For additional information concerning the merger solenoid, refer to Electrical system - Component identification Solenoids: Y-001 (Right header flotation solenoid) â&#x20AC;&#x201D; Y-048 (Engine decompression solenoid) (55.000)
Operation Prior to the merger speed operation, the universal control module A-001 will verify the park brake switch S-028 is in the OFF position, the seat switch S-002 is closed and the PTO engage switch S-017 is in the ON position. At key-on, the Ignition Control #2 Relay K-038 will energize and its normally open contact will close. The closed contact will allow current to flow to through the sensors fuse F-014, the PTO engage switch S-017, and then to the universal control module A-001. When the multi-function handle merger speed switch is actuated, it will send an increase or decrease merger speed signal to the universal control module A-001. The merger speed solenoid Y-022 uses a varying current supply sent by the merger speed switch, to allow a certain amount of supply oil to flow to the merger conveyor drive. INCREASE SPEED To increase the merger conveyor speed, actuate the top side of the multi-function handle (MFH) merger speed switch. The universal control module A-001 will receive an increase signal and energize the merger speed solenoid Y-022. As long as the multi-function handle merger speed switch is depressed, the merger speed solenoid Y-022 internal spool will move to allow a varying current to increase to 1500 mA . DECREASE SPEED To decrease the merger conveyor speed, actuate the bottom side of the multi-function handle (MFH) merger speed switch. The universal control module A-001 will receive a decrease signal and energize the merger speed solenoid Y-022. As long as the multi-function handle merger speed switch is depressed, the merger speed solenoid Y-022 internal spool will move to allow a varying current to decrease to 0 mA.

Control solenoids - Dynamic description - Merger height solenoids [YCG667001-] INT, [YCG667001-] NA
Brief Description The Merger height solenoid Y-025, the Merger deflector height solenoid Y-026, and Cylinder blocking solenoid Y-018 are some of the output devices associated with the merger operation. These solenoids will allow the operator to adjust the height of the merger and the merger deflector, by receiving a 12 V a Pulse Width Modulation (PWM) signal from Universal control module A-001. For additional information concerning the merger solenoids, refer to Electrical system - Component identification Solenoids: Y-001 (Right header flotation solenoid) â&#x20AC;&#x201D; Y-048 (Engine decompression solenoid) (55.000)
Operation Prior to the merger operation, the universal control module A-001 will verify the park brake switch S-028 is in the OFF position and the seat switch S-002 is closed. At key-on, the Ignition Control #2 Relay K-038 will energize and its normally open contact will close. The closed contact will allow current to flow through to the sensors fuse F-014, the PTO engage switch S-017, and then to the universal control module A-001 MERGER HEIGHT OPERATION RAISE When the multi-function handle (MFH) merger raise switch is actuated, the universal control module A-001 will receive a raise signal. After the universal control module A-001 has received the raise signal, it will energize the merger height solenoid Y-025 and the cylinder blocking solenoid Y-018. The energized cylinder blocking solenoid Y-018 will open a path to allow the supply oil to flow through the merger height solenoid Y-025, which in turn will raise the merger. LOWER When the multi-function handle (MFH) merger lower switch is actuated, the universal control module A-001 will receive a lower signal. After the universal control module A-001 has received the lower signal, it will de-energize the cylinder blocking solenoid Y-018. The de-energized cylinder blocking solenoid Y-018 will block the supply oil from flowing through the merger height solenoid Y-025, which in turn will lower the merger. MERGER DEFLECTOR OPERATION RAISE When the multi-function handle (MFH) merger deflector raise switch is actuated, the universal control module A-001 will receive a raise. After the universal control module A-001 has received the raise signal, it will energize the merger deflector height solenoid Y-026. The energized merger deflector height solenoid Y-026 will allow the supply oil to flow to the merger deflector cylinder, which in turn will raise the merger deflector. LOWER When the multi-function handle (MFH) merger deflector lower switch is actuated, the universal control module A-001 will receive a lower. After the universal control module A-001 has received the lower signal, it will de-energize merger deflector height solenoid Y-026. The energized merger deflector height solenoid Y-026 will redirect the supply oil to flow from the merger deflector cylinder, which in turn will lowers the merger.

Shield motor - Dynamic description [YCG667001-] INT, [YCG667001-] NA
Brief Description The Windrow shields motor M-018 is one of the output devices associated with the windrow shield system. The motor will allow the operator to select the width of the windrow by adjusting the windrow shield. The windrow shields motor M-018 can began adjusting the shield when it receives 12 V from the Windrow shield actuator extend relay K-026 or Windrow shield actuator retract relay K-027. For additional information concerning the windrow shields motor, refer to Electrical system - Component identification Motors: M-001 (Reel speed motor) — M-018 (Windrow shields motor) (55.000) and/or for information concerning the windrow relays refer to Electrical system - Component identification Relays: K-004 (Accessory control relay) — K-076 (Ignition control #1 relay) (55.000).
Operation Prior to the windrow shield operation, the universal control module A-001 will verify the seat switch S-002 is closed and the key switch S-004 is in the ACC position. At key-on, the Ignition Control #2 Relay K-038 will energize and its normally open contact will close. The closed contact will allow current to flow through to the controls fuse F-012. The universal control module A-001 will use the windrow shields position sensor B-057 to monitor the position of the shield. The windrow shields position sensor B-057 will use its variable resistor to record the shield's position and will send the position to the universal control module A-001. WINDROW SHIELD EXTEND When the top side of the windrow shields switch S-054 is actuated, the windrow shield actuator extend relay K-026 will become energized and its normally open contact will close. The closed contact will allow 12 V to travel to the windrow shields motor M-018 connector X-138 pin A. The connector X-138 pin B will remain grounded by the de-energized windrow shield actuator retract relay K-027. As 12 V is delivered to pin A, the motor will began move the shield outward away from the windrower for a wider windrow. WINDROW SHIELD RETRACT When the bottom side of the windrow shields switch S-054 is actuated, the windrow shield actuator retract relay K-027 will become energized and its normally open contact will close. The closed contact will allow 12 V to travel to the windrow shields motor M-018 connector X-138 pin B. The connector X-138 pin A will remain grounded by the de-energized windrow shield actuator extend relay K-026. As 12 V is delivered to pin B, the motor will began move the shield inward toward the windrower for a narrower windrow.

Header height control - Dynamic description - Flotation solenoids [YCG667001-] INT, [YCG667001-] NA
Brief Description The right header flotation solenoid Y-001 and the left header flotation solenoid Y-002 are some of the output devices associated with the Hydraulic Header System. When energized, the solenoids will allow the operator to adjust the height of the right side or left side of the header while moving. Each solenoid is energized by receiving a Pulse Width Modulation PWM signal from the Universal Control Module A-001. For additional information concerning the flotation solenoids, refer to Electrical system - Component identification Solenoids: Y-001 (Right header flotation solenoid) â&#x20AC;&#x201D; Y-048 (Engine decompression solenoid) (55.000)
Operation Prior to the header lift operation, the universal control module A-001 will verify the engine is running, the park brake switch S-028 is in the OFF position, the seat switch S-002 is closed and the PTO engage switch S-017 is in the ON position. When starting the windrower, the operator should verify the header drop speed and pressure set points are set correctly, by performing a header first lower cycle to charged the accumulators. HEADER FIRST LOWER CYCLE
When the multi-function handle (MFH) header lower switch is actuated, the unload solenoids ( Y-003 and Y-004), the header lower valves ( Y-007 and Y-008), and the flotation valves are all energized. The flotation solenoids will allow the operator to increase the pressure set-points when the operator actuate the right and left header trim switches ( S-014 and S-018). For additional information concerning first lower cycle, refer to Operator's Manual - Field Operation and/or Header height control - Dynamic description - Lower solenoids (55.662) and/or Header height control Dynamic description - Lower solenoids (55.662) At key-on, the Ignition Control #2 Relay K-038 will energize and its normally open contact will close. The closed contact will allow current to flow through to the sensors fuse F-014, the PTO engage switch S-017, and then to the universal control module A-001. The right header flotation solenoid Y-001 will allow the operator to control the header-right side flotation weight, while in motion, by actuating the top side (increase flotation) or the bottom side (decrease flotation) of the right header trim switch S-014. When the right header trim switch S-014is actuated, it will send a right side flotation weight signal to the universal control module A-001. The system will first energize the right unload valve solenoid Y-003 and then it will energize right header flotation solenoid Y-001. As long as the right header trim switch S-014 is depressed, current is applied to the right header flotation solenoid Y-001. When the 'increase flotation' side of the right header trim switch S-014 is actuated, the pressure set-points will increase and the header will feel lighter and vice versa. The flotation set-points will continue to change until the right header trim switch S-014 switch is released. For additional information concerning the unload valve solenoids, refer to Header height control - Dynamic description - Unload solenoids (55.662) The left header flotation solenoid Y-002 will allow the operator to control the header-left side flotation weight, while in motion, by actuating the top side (increase flotation) or the bottom side (decrease flotation) of the left header trim switch S-018. When the left header trim switch S-018 is actuated, it will send a left side flotation weight signal to the universal control module A-001. The system will first energize the left unload valve solenoid Y-004 and then it will energize the left header flotation solenoid Y-002. As long as the left header trim switch S-018 is depressed, current is applied to the left header flotation solenoid Y-002. When the 'increase flotation' side of the left header trim switch S-018 is actuated, the pressure set-points will increase and the header feel heavier and vice versa. The flotation set-points will continue to change until the left header trim switch S-018 switch is released.

Header height control - Dynamic description - Unload solenoids [YCG667001-] INT, [YCG667001-] NA
Brief Description The left unload valve solenoid Y-003 and the right unload valve solenoid Y-004 are some of the output devices associated with the Hydraulic Header System. When energized, the solenoids play an important role in the hydraulic header system by directing the oil supply to and from the correct valve manifold. Each solenoid is energized when it receives a Pulse Width Modulation (PWM) signal from the universal control module A-001. For additional information concerning the unload solenoids, refer to Electrical system - Component identification Solenoids: Y-001 (Right header flotation solenoid) â&#x20AC;&#x201D; Y-048 (Engine decompression solenoid) (55.000)
Operation Prior to the header lift operation, the universal control module A-001 will verify the engine is running, the park brake switch S-028 is in the OFF position, the seat switch S-002 is closed and the PTO engage switch S-017 is in the ON position. When starting the windrower, the operator should verify the header drop speed and pressure set-points are set correctly, by performing a header first lower cycle to charged the accumulators. HEADER FIRST LOWER CYCLE
When the multi-function handle (MFH) header lower switch is actuated the unload solenoids, the left and right header lower solenoids ( Y-007 and Y-008), and finally flotation solenoids ( Y-001 and Y-002) are all energized. The unload solenoids Y-003 and Y-004 provide the flotation solenoids Y-001 and Y-002 with relief pressure oil which will allow the flotation solenoids Y-001 and Y-002 to adjust the pressure of the set-point. For additional information concerning first lower cycle, refer to Header height control - Dynamic description - Lower solenoids (55.662) and/or Header height control - Dynamic description - Lower solenoids (55.662) At key-on, the Ignition Control #2 Relay K-038 will energize and its normally open contact will close. The closed contact will allow current to flow through to the sensors fuse F-014, the PTO engage switch S-017, and then to the universal control module A-001. The unload solenoids Y-003 and Y-004 main function is to direct supply oil to and from different manifold, depending on the header operation. When the universal control module A-001 will verify which operation is being activated, it will send a PWM signal to the left unload valve solenoid Y-003 and/or the right unload valve solenoid Y-004. HEADER LIFT OPERATION When the multi-function handle (MFH) header raise switch is actuated, the unload solenoids ( Y-003 and Y-004) will energize. The system will then energize the left and right header raise valve solenoids ( Y-005 and Y-006), which in turn will allow the header to raise. For additional information concerning the header raise solenoids, refer to Header height control - Dynamic description - Raise solenoids (55.662) When the multi-function handle (MFH) header lower switch is actuated, the unload solenoids ( Y-003 and Y-004) will energize. The system will then energize the left and right header lower valve solenoids ( Y-007 and Y-008), which in turn will allow the header to lower. For additional information concerning header lower solenoids, refer to Header height control - Dynamic description - Lower solenoids (55.662) HEADER TILT OPERATION When the multi-function handle (MFH) header tilt up switch is actuated, the header tilt solenoid Y-013 will energize. And soon after the left unload valve solenoid Y-003 will energize which in turn will close the tilt up direct path and the header will tilt up. For additional information concerning the tilt solenoid, refer to Header height control - Dynamic description - Tilt solenoid (55.662) In the header tilt down operation, the left unload valve solenoid Y-003 will remain de-energize and direct the supply oil to the tilt cylinders, which in turn will force the header to tilt downward/forward.

Brief Description The Left header lower valve solenoid Y-007 and the Right header lower valve solenoid Y-008 are some of the output devices associated with the Hydraulic Header System. These solenoids will allow the operator to lower the header, by receiving a 12 V Pulse Width Modulation (PWM) signal from the Universal Control Module A-001. For additional information concerning the lower solenoids, refer to Electrical system - Component identification Solenoids: Y-001 (Right header flotation solenoid) â&#x20AC;&#x201D; Y-048 (Engine decompression solenoid) (55.000)
Operation Prior to the header lower operation, the universal control module A-001 will verify the engine is running, the park brake switch S-028 is in the OFF position, the seat switch S-002 is closed and the PTO engage switch S-017 is in the ON position. When starting the windrower, the operator should verify the header drop speed and pressure set points are set correctly, by performing a header first lower cycle to charged the accumulators. HEADER FIRST LOWER CYCLE When the header lower switch is actuated, the right and left unload solenoids ( Y-003 and Y-004) will be energized first. Then the left and right lower solenoids ( Y-007 and Y-008) and finally the right and left header flotation solenoids ( Y-001 and Y-002) will all become energized. The flotation solenoids Y-001 and Y-002 will allow the operator to increase the pressure set-points when the operator actuate the right and left header trim switches ( S-14 and S-18). After setting the pressure set-points, the accumulators will began to charge to the set-points and the unload solenoids and the header lower solenoids will become de-energized. The flotation solenoids will remain energize but only up to 50 % of the pressure set-points. This will allow the flotation solenoids Y-001 and Y-002 the ability to quickly response to a lower or raise command. For additional information concerning first lower cycle, see Operator's Manual - Field Operation. At key-on, the Ignition Control #2 Relay K-038 will energize and its normally open contact will close. The closed contact will allow current to flow through to the sensors fuse F-014, the PTO engage switch S-017, and then to the universal control module A-001 When the multi-function handle (MFH) header lower switch is actuated, a header lower signal is sent to the universal control module A-001. After the universal control module A-001 has received the lower signal, the unload solenoids Y-003 and Y-004 and the flotation solenoids, Y-001 and Y-002 will energize. The system will then energize the header lower solenoids, which in turn directs supply oil through Y-001 and Y-002 to charge the accumulators to the pre-set pressure set-points. Once the accumulators are fully charged, the header will "float" at the pre-set pressure set-points and the unload solenoids Y-003 and Y-004 will de-energized. Soon after the left and right header float solenoids ( Y-009 and Y-010) will energize, which will allow the supply oil to flow into the accumulator and the header will lower until the oil pressure has equalize between the lift cylinders and the header lower solenoids.

Brief Description The header tilt solenoid Y-013 is one of the output devices associated with the Hydraulic Header System. The solenoid will allow the operator to adjust the right side or left side of the header at a stationary position, when it receives a 12 V Pulse Width Modulation (PWM) signal from the universal control module A-001. For additional information concerning the tilt solenoid, refer to Electrical system - Component identification Solenoids: Y-001 (Right header flotation solenoid) â&#x20AC;&#x201D; Y-048 (Engine decompression solenoid) (55.000)
Operation Prior to the header tilt operation, the universal control module A-001 will verify the engine is running, the park brake switch S-028 is in the OFF position, the seat switch S-002 is closed and the PTO engage switch S-017 is in the ON position. At key-on, the Ignition Control #2 Relay K-038 will energize and its normally open contact will close. The closed contact will allow current to flow through to the sensors fuse F-014, the PTO engage switch S-017, and then to the universal control module A-001. NON-DRAPER HEADER The header tilt solenoid Y-013 will allow the operator to control the header tilt operation when the right side (up) or the left side (down) of the multi-function handle (MFH) header tilt switch is actuated. The header will continue to tilt up or down until the header tilt switch is released. UP OPERATION When the right side (up) of the multi-function handle (MFH) header tilt switch is actuated, it will send a tilt up signal to the universal control module A-001. The universal control module A-001 will send a PWM signal to the header tilt solenoid Y-013, which in turn will trigger the header tilt solenoid Y-013 to open a direct path through the Independent Control Valve ICV manifold. Soon after the header tilt solenoid is energized, the left unload valve solenoid Y-003 will energize and close that same path so the supply oil can flow to the return tank. The supply oil will flow through the ICV and fill up the tilt cylinders, which in turn will tilt the header up. For additional information concerning the unload valves, refer to Header height control - Dynamic description - Unload solenoids (55.662) DOWN OPERATION When the the left side (down) of the multi-function handle (MFH) header tilt switch is actuated, it will send a tilt down signal to the universal control module A-001. The universal control module A-001 will send a PWM signal to the header tilt solenoid Y-013, which in turn will trigger the header tilt solenoid Y-013 to open a flow path through the valve. The left unload valve solenoid Y-003 remain de-energized and will direct the supply oil from the ICV to the tilt cylinder. As the supply oil fills the tilt cylinders the weight of the header forces it to tilt down. DRAPER HEADER The header tilt solenoid Y-013 will allow the operator to control the header tilt operation when the top side (fore) or the bottom side (aft) of the header tilt switch S-101. The header will continue to tilt fore or aft until the header tilt switch S-101 is released. FORE OPERATION When the fore side of the header tilt switch S-101 is actuated, it will send a tilt fore signal to the universal control module A-001. The universal control module A-001 will send a PWM signal to the header tilt solenoid Y-013, which in turn will trigger the header tilt solenoid Y-013 to open a direct path through the Independent Control Valve ICV manifold. Soon after the header tilt solenoid is energized, the left unload valve solenoid Y-003 will energize and close that same path so the supply oil can flow to the return tank.

Brief Description The Left draper lift position solenoid Y-036 and the Right draper lift position solenoid Y-037 are some of the output devices associated with the Hydraulic Draper-Header System. These solenoids will allow the operator to lift the draper, when it receives a 12 V Pulse Width Modulation (PWM) signal from the universal control module A-001. For additional information concerning the draper lift solenoids, refer to Electrical system - Component identification Solenoids: Y-001 (Right header flotation solenoid) â&#x20AC;&#x201D; Y-048 (Engine decompression solenoid) (55.000)
Operation Prior to the draper liftoperation, the universal control module A-001 will verify the engine is running, the park brake switch S-028 is in the OFF position, the seat switch S-002 is closed and the PTO engage switch S-017 is in the ON position. At key-on, the Ignition Control #2 Relay K-038 will energize and its normally open contact will close. The closed contact will allow current to flow through to the sensors fuse F-014, the PTO engage switch S-017, and then to the universal control module A-001 DRAPER RAISE When the multi-function handle (MFH) draper raise switch is actuated, the universal control module A-001 will first energize the draper unload solenoid Y-038. The energized draper unload solenoid Y-038 will allow the supply oil to flow from the supply port to the left draper lift position solenoid Y-036. Then the universal control module A-001 will energize the left draper lift position solenoid Y-036 and the cylinder blocking solenoid Y-018 (6cyinder only). The left draper lift position solenoid Y-036 will raise the left draper cylinder and the cylinder blocking solenoid Y-018 will allow the oil supply to flow and raise the right draper cylinder. DRAPER LOWER When the multi-function handle (MFH) draper lower switch is actuated, the draper unload solenoid Y-038 will remain de-energized. The de-energize draper unload solenoid will allow the supply oil to flow from the left draper lift position solenoid Y-036 to the tank reservoir. Then the universal control module A-001 will energize the left draper lift position solenoid Y-036 and the cylinder blocking solenoid Y-018 (6cyinder only). The left draper lift position solenoid Y-036 will lower the left draper cylinder and cylinder blocking solenoid Y-018 will allow the oil supply to flow and lower the right draper cylinder. The hydraulic draper circuit also includes a flow divider/combiner that provides synchronize flow in both directions to the draper lift cylinders, which in turn will move each cylinders at the same time. DRAPER TILT When the multi-function handle (MFH) draper tilt switch is actuated, the universal control module A-001 will first energize the draper unload solenoid Y-038. The energized draper unload solenoid Y-038 will allow supply oil flow to the right draper lift position solenoid Y-037. Then the universal control module A-001 will energize the right draper lift position solenoid Y-037 and the equalization solenoid Y-019. The right draper lift position solenoid Y-037 will tilt the right side of the draper and the equalization solenoid Y-019 will allow the oil supply to flow and tilt the left draper cylinder.

Rotary screen drive motor - Dynamic description [YCG667001-] INT, [YCG667001-] NA
Brief Description The Screen cleaner motor M-009 is an output device associated with the screen cleaner system. Once the windrow's engine is running, the motor will receive 12 V and begin removing dust and debris from the incoming outside air to the air cleaner. For additional information concerning the screen cleaner motor, refer to Electrical system - Component identification Motors: M-001 (Reel speed motor) — M-018 (Windrow shields motor) (55.000)
Operation Prior to the screen cleaning operation, the universal control module A-001 will verify the seat switch S-002 is closed and the key switch S-004 is in the IGN position. At key-on, the ignition control #3 relay K-033 will energize and its normally open contact will close. The closed contact will allow current to flow through to the screen cleaner fuse F-003. As long as the windrower's engine is running, the screen cleaner motor M-009 will receive 12 V through the screen cleaner fuse F-003. While the engine is running, outside air is drawn in by windrower's engine fan and the screen cleaner motor M-009 will remove any debris from the screen. This will allow air to flow without restriction to the windrow's air cleaner, turbocharger, and finally the intake manifold. The air cleaner will remove all the impurities and send large particles through its evacuator hose and out the exhaust stack. The turbocharger will pressurize the cleaned air and pass it to the intercooler to remove heat, and then to the intake manifold. This overall process ensures that clean air is flowing, for an efficient engine cooling system.

E0513-02-Common Rail Pressure Limiting Valve Failure - Data Erratic, Intermittent or Incorrect Control Module : ECU Context: This engine fault code indicates that the Engine Control Module A-003 has determined that the Pressure Relief Valve did not open after a pressure shock (kickoff). Normally the fuel pressure in the rail is regulated by the metering unit of the high pressure pump. However, if this component is malfunctioning the rail pressure can rise to critical levels. For this reason the common rail has a Pressure Relief Valve which is a mechanical safety valve (no electrical connectors) that opens at a certain pressure level. An opening of the Pressure Relief Valve is detected by evaluating the gradient of the rail pressure (calculated by the Engine Control Module). If the Pressure Relief Valve does not open on its own after exceeding the pressure threshold it can also be forced open by a so-called 'kickoff' or pressure shock when the metering valve of the high pressure fuel pump is set to maximum possible quantity. Rail pressure in excess of 148500 kPa (21538.1 psi) for 1 s evokes a kickoff (pressure shock) request by the Engine Control Module. If the pressure shock (kickoff) request is present longer than 2 s and did not immediately open the Pressure Relief Valve, this error will occur. This fault will only be cleared after an Engine Control Module reset. Possible failure modes: 1. Faulty Engine Control Module A-003, improper data set. 2. Faulty Pressure Relief Valve, mechanical valve does not function. Solution: 1. Use the EST to flash the Engine Control Module A-003 with the appropriate data set. A. If the error reoccurs, replace the Pressure Relief Valve. B. If the error does not reoccur, return the machine to service.

E0525-03- Injector Cylinder 6 Failure - Shorted to high source [YCG667001-] INT, [YCG667001-] NA
Control Module : ECU NOTE: This diagnostic procedure requires a good quality Digital Multi-meter (DMM) to be able to take accurate resistance measurements. The meter should be able to measure to a resolution of 0.1 ohms. Some of the measurements required to be taken, could be as low as 0.5 ohms and any inaccuracies in the DMM could cause a technician to take the wrong diagnostic path. Injector coil resistance, at the injector, is 0.56 - 0.57 Ί. Make sure that the multi-meter's test lead resistance is taken into account when resistance measurements are taken. Record the multi-meter's test lead resistance by touching the leads together on the lowest Ohms scale and mentally recording the resistance value. Subtract this value from the actual resistance measurement taken. Context: The Engine Control Module A-003 generated an error associated with the injector power driver stage. The power stage component of the Engine Control Module energizes the unit injection system transistors and simultaneously observes the current flow (sense resistors) in the high-side and low-side switching branches. If there is a deviation from the expected current flow, the driver circuitry detects the specific error and reports it back to the Engine Control Module. The Engine Control Module will process the error message so that it records information on performed injections, cylinder bank specific errors and cylinder specific errors. The error message is then compared to applicable error patterns and if there is a match, a fault code is generated. If an error message doesn't match any pattern, the error is treated as unclassifiable. This monitoring function is performed once per camshaft revolution. Cause: The Engine Control Module A-003 has determined that there is a fault associated with the current monitoring of the injector output power driver stage. Possible failure modes: 1. Faulty injection valve or shorted solenoid windings. 2. Faulty electrical wiring, short to high source or damaged wiring harness. 3. Faulty Engine Control Module A-003. Solution: 1. Verify this fault code is still present and in an active state. A. If the fault is still present and active, continue with step 2. B. If the fault is no longer present or is in an inactive state, return machine to proper operation. 2. Carefully disconnect the engine cylinder harness from the ECU at connector X-036. Place the key switch ON. Use a multi-meter to check for voltage, on the ECU harness side of connector X-036, from pin 15 to chassis ground and pin 2 to chassis ground. There should be no voltage. A. If there is voltage, leave connector X-036 disconnected and continue with step 3. B. If there is no voltage, leave connector X-036 disconnected and continue with step 4. NOTE: In-line 4 way connectors at valve cover for paired injectors not shown on electrical schematic frame 3. Disconnect the engine injector harness from the injector pair (valve cover) base connector for Cylinders #5 and #6. Use a multi-meter to check for voltage on the engine injector harness side of the injector pair (valve cover) connector from pin 1 to chassis ground and pin 2 to chassis ground. There should be no voltage. A. If there is voltage on either or both pins to chassis ground, there is a short to a voltage source in the engine injector harness between the injector pair (valve cover) connector and the Engine Control Module connector X-036. Locate and repair damaged wiring. B. If there is no voltage on either pin to chassis ground, there is a short to a voltage source between the injector pair (valve cover) base connector and the injector. Locate and repair damaged wiring.

4. Place the key switch OFF. Use a multi-meter to measure the resistance, on the ECU harness side of connector X-036 pin 2 to pin 15. There should be 0.5 - 0.6 Ί. A. If the resistance is correct, the ECU may have failed. Try reloading the ECU software and if the fault reoccurs, replace the ECU. B. If the resistance is incorrect, continue with step 5. NOTE: In-line 4 way connectors at valve cover for paired injectors not shown on electrical schematic frame 5. Disconnect the engine injector harness from the injector pair (valve cover) base connector and use a multi-meter to measure the resistance on the injector (valve cover) side of the connector between pins 1 and 2. There should be 0.5 - 0.6 Ί. A. If the resistance is within range, the fault condition is in the engine harness between the injector pair (valve cover) base connector and the ECU engine harness connector X-036, locate and repair the damaged conductors. B. If the resistance was lower than range minimum, continue with step 6 6. Remove the injector (valve) cover. Disconnect the harness from the Cylinder 6 injector at connector X-313. Use a multi-meter to check for continuity on the Cylinder 6 injector from terminal 1(+) to chassis ground and from pin 2 (-) to chassis ground. There should not be continuity to ground. A. If there is continuity on either or both checks to ground, the solenoid coil is grounded. Replace the injector. B. If there is no continuity, continue with step 7. 7. Measure the coil resistance. Use a multi-meter to measure the resistance, on the Cylinder 6 injector, from terminal 1 to terminal 2. There should be 0.5 - 0.6 Ί. A. If the resistance is within range, there is a short circuit in the wiring harness. Locate and repair damaged wiring. B. If the resistance is lower than minimum range, the Cylinder 6 injector solenoid coil has failed. Replace the injector. Wire harnesses - Electrical schematic frame 56 (55.100.DP-C.20.E.56)

E0533-03- Setpoint of Rail Metering Unit not Plausible in Overrum Shorted to High Source Control Module : ECU Context: This engine fault code indicates that the Engine Control Module A-003 has determined that the Metering Unit (Fuel High Pressure Pump Y-039) has excessively opened to reach the desired Rail pressure. The monitoring is only active if the high pressure governor (Fuel High Pressure Pump) is operating in closed loop control, the engine is in overrun condition, the fuel injection quantity is zero and the monitoring has not been inhibited by other faults. This error is the result of leakage in the high pressure section; injection nozzle stuck in open position, worn or defective high pressure pump, worn injector, leaking pressure relief valve. or leakage in the low pressure system; 'Zero delivery' is not active in metering unit (excessive leakage in metering unit). Cause: The rail pressure is monitored by various fault paths during active pressure control by the metering unit. The fault path at hand detects an excessive leakage of fuel by monitoring the set-point value of the fuel volume flow through the metering unit during overrun. If the set-point value of the rail pressure governor for the fuel volume flow through the metering unit exceeds an upper limit over 2.5 s this error will occur. [This limit is interpolated from the rail pressure dependent curve, established by the Engine Control Module].

E0535-03- Fuel Flow Setpoint of Common Rail Metering Unit too low - Shorted to High Source Control Module : ECU Context: Engine fault code E0535-03 indicates that the Engine Control Module A-003 has determined that there is either Fuel System Leakage or the Metering Unit (High Pressure Fuel Pump Y-039) is jammed in closed position. The monitoring is only active if the high pressure governor (High Pressure Fuel Pump) is operating in closed loop control, the rail pressure governor deviation is within the range +/- 5000 kPa (725.2 psi) and the monitoring has not been inhibited by other faults. This error is the result of an inaccurate Rail pressure sensor or defective high pressure pump in the high pressure system or Metering unit reflux too low, fuel system leakage, or metering unit jammed in the closed position in the low pressure system. Cause: The rail pressure is monitored by various fault paths during active pressure control by the metering unit. The fault path at hand detects a leakage of fuel by monitoring the set-point current used to control the metering unit. If the metering unit current control set-point current is below a calculated minimum limit over 2.5 seconds this error will occur. [This limit is calculated from various curves, maps and correction factors established by the Engine Control Module A-003].

E0323-13- MFH position sensor - Needs calibration [YCG667001-] INT, [YCG667001-] NA
Control Module : UCM Context: In order for the windrower to be driven in the forward or reverse direction, the operator must move the Multifunction Handle (MFH) S-49 NH/ S-51 CIH from the neutral position. The windrower's ground speed will increase, as the MFH is moved away from the neutral position. And the ground speed will decrease as the MFH is moved closer to the neutral position. When the operator has moved the MFH forward or reverse, the controller will then instruct the MFH Position Sensor B-054 to measure the angular position of MFH and the Propulsion Cylinder Position Sensor B-061 to measure the position of the hydraulic cylinder. The controller compares the two measurements to determine the cylinder position error, which it will use to determine what direction and how far to move the hydraulic cylinder which in turns moves the windrower in the forward or reverse direction. Cause: MFH pot full Fwd EEPROM value is out of calibration. Possible failure modes: 1. Faulty MFH position sensor. Solution: 1. Verify this fault is still present and in an active state. A. If the fault is still present and active, continue to step 2. B. If the fault is no longer present or inactive, return machine to proper operation. 2. Use the Cab controls - Overview – Dealer setup/diagnostics tests (55.512) to access the “Propulsion Inputs” tests within the “Inputs” test menu. Select the component name “MFH Position” and observe the voltage value on the third line as you move the MFH lever away from the neutral position to its end of travel position (full forward position). The normal operating range is 0.88 - 1.34 V. A. If the voltage reading is out of range, the sensor has failed. Replace the sensor and repeat step 1. B. If the voltage reading is within the proper limits, the fault may be intermittent. Return the machine to proper operation. Wire harnesses - Electrical schematic frame 09 (55.100.DP-C.20.E.09)

Control Module : UCM Context: In order for the windrower to be driven in the forward or reverse direction, the operator must move the Multifunction Handle (MFH) S-49 NH/ S-51 CIH from the neutral position. The windrower's ground speed will increase, as the MFH is moved away from the neutral position. And the ground speed will decrease as the MFH is moved closer to the neutral position.
