INTRODUCTION

Foreword - Ecology and the environment 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.

INTRODUCTION

Safety rules Important notice to operators Your machine may be equipped with special guarding or other devices in compliance with local legislation. Some of the guarding or safety devices require active use by the operator. Check local legislation on the usage of this machine.

Accident prevention Farm accidents can be prevented with your help. No accident prevention program can be successful without the wholehearted cooperation of the person who is directly responsible for the operation of the equipment. To read accident reports from all over the country is to be convinced that a large number of accidents can be prevented only by the operator anticipating the result before the accident is caused and doing something about it. It is said that "The best kind of safety device is a careful operator who with care and mature consideration can save more lives and limbs than any accident prevention program which is not adhered to". Further in this chapter you will find a list of the most important safety precautions. Take time to read and follow the instructions and furthermore, be careful! Some pictures in this manual may show the safety guarding open or removed to better illustrate a particular feature or adjustment. Ensure to close or replace all guards before operating the machine.

General and operating safety Most farm machinery accidents can be avoided by the observance of a few simple safety precautions. 1.

The machine must only be used by a skilled operator familiar with all the controls and harvesting techniques on cultivated land with slopes up to maximum 26 % ( 15 Â°) uphill and downhill.

Do not permit anyone other than the operator to ride on the machine.

Before starting the engine, ensure everyone is clear of the machine.

Warn bystanders by sounding the horn several times.

Keep children away from and off the machine at all times.

No-one should be standing on the ladders when the machine is moving.

When driving on public roads, observe traffic regulations, adapt your speed to road and traffic conditions and ensure that all lights and other safety mechanisms on the machine (if they are required) are fitted and work properly. The grain tank must be empty when driving on the road. Ensure that the unloading tube is locked in its closed position.

Ensure that both brake pedals are locked together when travelling on public roads.

Ensure the hazard warning signs provided are installed at the front and the rear of the machine and use the rotating amber traffic warning beacon(s) (if equipped) when driving on public roads to indicate the vehicle is of abnormal size and is slow-moving.

10. Do not brake abruptly to avoid tipping of the machine. 11. Do not exceed 20 km/h (12.5 mph) when driving downhill. If necessary, change into a lower gear before starting the descent. 12. Never travel at high speed in crowded areas. 13. Avoid making turns at high speed. 14. When driving on public roads, either with the grain header loaded on a trailer and attached to the rear of the machine, or with the grain header still attached to the machine (provided local legislation allows), always be aware and conscious of its size. 47377790 31/10/2012

INTRODUCTION

15. Before operating the machine ensure that all safety guards are installed. 16. Check the wheel nuts torque as described in MAINTENANCE. 17. Do not enter the grain tank while the machine engine is running. With engine stopped, use a wooden clearing club should the grain tank unloading auger become bridged. Take utmost care not to be pulled into the grain tank in case un-bridging is required. 18. Do not attempt to clean, lubricate or carry out any adjustments on the machine while it is in motion or while the engine is running. 19. Never leave the operator's platform without first disengaging the machine drive mechanism, lowering the header, stopping the engine, applying the park brake and removing the ignition key. 20. Do not work under the machine header unless it is securely blocked and/or the header safety latch is engaged. 21. Do not work around the machine in loose clothing that might catch in any of the moving parts. 22. Keep hands away from moving parts of the machine. 23. Keep the fire extinguisher within easy reach of the operator. Ensure to replace it by a similar type of extinguisher or have it checked or refilled after every usage and/or date of expiry. 24. Do not step on the grain tank extensions, covers, or the cab roof. 25. Machine dust can cause "farmer's lung" disease. It may also contain harmful spraying residues. Keep the cab door and window closed during operation. Wear a dust mask when cleaning the accumulated dust and debris on the machine.

Hydraulic system safety • Hydraulic oil leaking under pressure can penetrate the skin and cause infection or other injury. To prevent personal injury: • Relieve all pressure before disconnecting fluid lines. • Before applying pressure, make sure all connections are tight and 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, seek medical attention immediately. • The hydraulic hoses and fittings on your machine meet engineering specifications for the particular function. When replacing damaged, blown or worn hoses or fittings, use only manufacture authorized service parts. • Care in hydraulic hose installation is a must: • Make sure pressure is relieved before starting installation procedure. • DO NOT kink or twist a hose, failure may occur. • Properly route the hose. • Have a certified hydraulic technician install the hose. • Remove air from the hydraulic system after installing any hydraulic component. • Periodically check hydraulic system for leaks or damage. check for: • Leaks at hose fitting or in hose. • Damaged hoses and/or fittings. • Kinked, crushed, flattened, hard blistered, heat cracked, charred, twisted, soft or loose covered hoses. • Corroded or damaged fittings. • Leaking ports. • Excessive dirt and debris around hoses and/or fittings. • Damaged or missing hose retaining clamps, guards, shields, etc. • DO NOT stand on or use a hose as a step. DO NOT pull or apply external forces to the hose. The hose may fail and cause injury. • Keep all persons away from the working area. Mechanisms controlled by fluid power can become hazardous if a hose fails. Lifted mechanisms can fall to the ground, machine steering may fail, etc. 47377790 31/10/2012

INTRODUCTION

• Stay clear of a pressurized hose assembly that has blown apart. Hose fittings can be thrown off at high speed and a loose hose can whip around with great force. • Hydraulic fluid can reach high temperatures. Allow fluid to cool before servicing the system. • Escaping fluid under pressure may form a mist or fine spray which can flash or explode upon contact with an ignition source. • Vibration can reduce hose service life. Make sure all retaining clamps and/or devices are secured. • Environmental conditions can cause hose and fittings to deteriorate. Inspect hydraulic hoses periodically. Replace worn or damaged hoses and fittings.

Safety requirements for fluid power systems and components - Hydraulics (European standard PR EN 982) Flexible hose assemblies must not be constructed from hoses which have been previously used as part of a hose assembly. Do not weld hydraulic piping. When flexible hoses or piping are damaged, replace them immediately. It is forbidden to modify a hydraulic accumulator by machining, welding or any other means. Before removing hydraulic accumulators for servicing, the liquid pressure in the accumulator must be reduced to zero. Pressure check on hydraulic accumulators shall be carried out by method recommended by the accumulator manufacturer. Care must be taken not to exceed the maximum allowable pressure of the accumulator. After any check of adjustment there must be no leakage of gas.

Danger of death by electrocution! Pay special attention to the overhead power lines. Make sure the machine has sufficient clearance to pass in all directions (also with raised or opened machine components). Also think of the radio aerial(s) or any other factoryfitted accessory or parts which may have been added afterwards. Should a contact between the machine and an electric power line occur, then the following precautions must be taken: Stop the machine movement immediately, stop the engine and apply the hand-brake or parking brake. Check if you can safely leave the cab or your actual position without direct contact with electric wires. If not, stay in your position and call for help. If you can leave your position without touching the lines, jump off the last step or support position to ensure that there is no contact between any part of your body and the ground at any time. Do not touch the machine afterwards until power to the lines has been shut off. When people approach the machine, warn them not to touch the machine but to ask the electric power supply company to shut off the power to the lines.

Engine safety 1.

Keep the engine area clean of dust, chaff and straw to prevent the possibility of fires.

Never idle the engine in an enclosed area as harmful exhaust gases may build up.

Wear a suitable hearing protective device, such as ear muffs or ear plugs, if you are exposed to noise which you feel is uncomfortable.

The cooling system operates under pressure which is controlled by the radiator cap. It is dangerous to remove the cap while the engine is hot.

Switch off the engine and wait until it has cooled. Even then use extreme care when removing the cap. Cover the cap with a rag and turn it slowly to the first stop to allow the pressure to escape before removing the cap completely. Stand clear of the radiator opening as hot coolant may splash out.

Never add cold water to a hot radiator. Failure to follow these instructions may result in serious personal injury from hot coolant or steam blowout and/or damage to the cooling system or engine.

INTRODUCTION

Antifreeze contains monoethylene glycol and other chemicals which are toxic if taken internally and can be absorbed in toxic amounts through repeated or prolonged skin contact. Follow these precautions when working with antifreeze:

Do not take antifreeze internally. If antifreeze is swallowed accidentally, obtain medical attention immediately.

Keep antifreeze in sealed containers out of reach of children, livestock or pets.

10. Periodically check the engine coolant and heater hoses for signs of wear, deterioration, weak sections and leaks to avoid hazardous situations and possible injury caused by hot coolant. 11. The fuel oil in the injection system is under high pressure and can penetrate the skin. Unqualified persons should not remove or attempt to adjust a fuel injection pump, injector, nozzle or any other part of the fuel injection system. Failure to follow these instructions may result in serious injury. If fuel is injected through the skin, medical assistance should be obtained. 12. Be very careful to avoid contact with hot engine oil. If the engine oil is extremely hot, allow the oil to cool to a moderately warm temperature for safe removal. 13. Do not handle a hot oil filter with bare hands. 14. Continuous and prolonged contact with used engine oil may cause skin cancer. Protect your skin by wearing heavy plastic gloves. If oil gets onto the skin, wash promptly with soap and water.

Diesel fuel safety 1.

Under no circumstances should gasoline, alcohol or blended fuels be added to diesel fuel. These combinations can create an increased fire or explosive hazard. In a closed container, such as a fuel tank, such blends are more explosive than pure gasoline. Do not use these blends.

Never remove the fuel tank cap or refuel with the engine running or hot. Refuel the machine only when the engine has been turned off. Do not smoke or use a naked flame when refuelling or when standing near fuel tanks.

Maintain control of the fuel filler pipe nozzle when filling the tank.

Do not fill the fuel tank to capacity. Allow room for expansion.

Wipe up spilled fuel immediately.

Always tighten the fuel tank cap securely.

If the original fuel tank cap is lost, replace it with an NEW HOLLAND AGRICULTURE cap. A non-approved, proprietary cap may not be safe.

Keep equipment clean and properly maintained.

Do not drive equipment near open fires.

10. Never use fuel for cleaning purposes.

Battery safety WARNING Explosion hazard! Batteries emit explosive gases. Always ventilate when using in an enclosed area or when charging. Keep the battery away from sparks, open flames, and other ignition sources. Failure to comply could result in death or serious injury. W0369A

WARNING Battery acid causes burns. Batteries contain sulfuric acid. Battery electrolyte contains sulfuric acid. Contact with skin and eyes could result in severe irritation and burns. Always wear splash-proof goggles and protective clothing (gloves and aprons). Wash hands after handling. Failure to comply could result in death or serious injury. W0120A

The essential precautions listed below must be observed: â&#x20AC;˘ Do not use an open flame to check the electrolyte level. Keep sparks, flames and lighted tobacco away. â&#x20AC;˘ Do not produce sparks with cable clamps when charging the battery or starting the engine with a slave battery. 47377790 31/10/2012

INTRODUCTION

• Wear eye protection when working near batteries. • Wear eye protection and gloves if removing the battery cover plugs. • Provide ventilation when charging or using in an enclosed space. • Ensure the vent plugs are correctly installed and tight. If the electrolyte comes into contact with the skin, eyes or is taken internally, treat as follows: • Skin: Flush with cold water. • Eyes: Flush with cold water for 10 minutes and get prompt medical attention. • Internal: Call a doctor immediately.

Fire and explosion prevention • Due to the flammable nature of the crop materials encountered, fire risks are high. This risk can be minimized by frequent removal of accumulated crop material from the machine and checking for overheated machine components. If oil leaks appear, re-torque bolts or replace gaskets as necessary. • Remove all trash or debris from the machine each day. Especially check the engine area and exhaust system. • Sparks or flame can cause the hydrogen gas in a battery to explode. To prevent an explosion do the following: • When disconnecting the battery cables, disconnect the negative (▬) cable first; when connecting the battery cables, connect the negative (▬) cable last. • When connecting jumper cables to start the engine, use the procedure shown in this manual (see Auxiliary Battery connections in this manual). • Do not short circuit the battery posts with metal items. • Do not weld, grind or smoke near a battery. • Sparks from the electrical system or engine exhaust can cause an explosion and fire. Before you operate this machine in an area with flammable dust or vapors, use good ventilation to remove the flammable dust or vapors. • Use nonflammable cleaning solvent to clean parts. • A fire can cause death or injury. Always have fire extinguisher near or on the machine. Make sure the fire extinguishers are serviced according to the manufacturers instructions. • If a fire extinguisher has been used, always recharge or replace the fire extinguisher before operating the machine. • Keep the cooling system clean and maintain the correct coolant level. • Make sure that you DO NOT store oily rags or other flammable materials on the machine. • Engine fuel can cause an explosion or fire. Do not fill the fuel tank with the engine running; if you are near an open fire; or if you are welding, smoking, etc. • If the machine has an oil, fuel or hydraulic leak, always repair the leak and clean the area before operating. • Check the electrical system for loose connections or frayed insulation. Repair or replace the loose or damaged parts. • Before welding or using a torch on the machine, clean the area to be repaired.

Wheels and tires The life and performance of the tires depends largely upon maintaining the correct pressure. Keep the tires inflated to the pressures given in SPECIFICATIONS. Check the wheel nuts torque daily during the first week of operation and thereafter on a weekly basis. The wheel nut torque is given in SPECIFICATIONS. Whenever preparing to jack-up the machine, park on a level, firm surface and securely block the drive tire opposite the side to be lifted, both in front and rear.

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 unless instructed otherwise. • 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. • While 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 jeopardize 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.

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 machineâ&#x20AC;&#x2122;s NEW HOLLAND AGRICULTURE Warranty coverage.

Clutch - Clutch and components

Clutch - Overview Description The units with 8x8 mechanical shuttle transmissions use a conventional clutch to connect engine power to the transmission. The clutch is conventionally located at the front of the transmission, connecting the engine to the transmission input shaft. The clutch system is comprised of the following components: • Clutch disc • Pressure plate • Pilot bearing • Release bearing The clutch system is a cable operated single plate clutch with a 330.2 mm (13 in) non-asbestos dry friction disc, designed for high durability and low-effort operation. The pressure plate is a diaphragm spring type, which is selfadjusting and requires no maintenance.

Operation With the clutch engaged, the spring loaded pressure plate forces the clutch disc into contact with the engine flywheel. The frictional contact between the clutch disc material and the surfaces of the flywheel and pressure plate transmits drive from the flywheel, via the clutch disc, to the input shaft of the transmission. A cable connects the clutch pedal to the release bearing. The release bearing contacts the operating fingers of the pressure plate. Depression of the clutch pedal causes the release bearing to move forward and depress the pressure plate diaphragm, thus drawing the pressure plate away from the clutch disc and releasing the disc from contact with the flywheel. The frictional drive from the engine to the transmission is thereby disconnected. When the clutch pedal is released, a spring returns the pedal to its free position and the release bearing is drawn away from the release levers of the pressure plate assembly. The main springs of the pressure plate assembly then re–assert pressure on the pressure plate moving it towards the friction disc and into contact with the flywheel, which re–establishes the drive between engine and transmission.

Inspect the friction disc. Make sure the linings are not loose, cracked, worn out or dirtied by oil. Check the rivets. If there are signs of overheating due to clutch slippage, replace the disc with a new one.

NOTE: Investigate reason for any oil or grease on surfaces. Repair before mounting new disc. 2.

Inspect pressure plate. Check that all pins are the same height, that there is no discoloration due to overheating, and that the entire assembly works properly. Check for cracks, scratches or distortion on the surface of the pressure plate. Dispose of pressure plate if any of the above failures are found.

NOTE: The diaphragm clutch has no replacement parts. Replace the whole assembly if any problem is found during inspection. 3.

Make sure the thrust bearing and hub move freely inside the hub support. Ensure the bearing rotates smoothly and that external side is not damaged or worn out. Look for cracks or distortion on clutch release fork. For example, make sure that all the pins are aligned and not worn out. Remove and replace any broken or defective parts.

If needed, check the thrust bearing. Use a puller (1) with a suitable attachment (3) and a stack plate (4) to separate the thrust bearing (2) from the hub.

Clutch - Troubleshooting Problem No movement when a gear is selected and the clutch pedal is let out.

With foot on the clutch pedal, engine speed raises but drive speed stays the same. It is very difficult to change gears.

Possible Cause Failure in rear axle or in transmission.

Clutch maladjustment. Thrust bearing is not moving. Chafing of friction disc. Pressure plate failure. Clutch disc slips.

Correction Connect differential lock. If tractor moves, failure is on differential outlet. If machine does not move, possible failure in transmission or in rear axle. Adjust clutch. • Check linkage. Replace friction disc. Repair or replace pressure plate. • Check clutch disc adjustment. • Chafing of clutch disc.

• Pressure plate failure. Clutch drag (does not let out completely). • Check clutch adjustment. • Chafing of clutch disc.

It is impossible to put in Clutch does not disengage. gear, engine stalls when machine is still, with foot on clutch pedal.

Noise due to transmission Chafing of thrust bearing. bell. Noise changes when putting foot on clutch pedal and letting it out. Chafing of clutch pilot bearing. Clutch does not engage Faulty clutch disc. gently. Faulty pressure plate. Chafing of clutch pilot bearing. Faulty flywheel.

Transmission - Power Shuttle transmission

Power Shuttle transmission - Static description The Power Shuttle valve is used in the 8 x 8 and 16 x 8 Power Shuttle transmissions. The transmissions use an F/R control valve, which is comprised of two sections. The upper section of the valve incorporates a system pressureregulating valve 1500 - 1800 kPa (217.6 - 261.06 psi), as well as the port to the oil cooler, the cooler by-pass valves, and the lubrication pressure relief valve. The forward section includes a pressure sensor, which sends a signal to the instrument cluster. The lower section contains two spools, one of which is shifted by the FNR lever on the left-hand side of the steering wheel. The other spool activates by the movement of the inch pedal and serves to enable gear changes.

Transmission - Power Shuttle transmission

Power Shuttle transmission - Static description of the 16 x 8 Power Shuttle transmission The transmission incorporates mechanical gear shifters and a power shuttle control valve on the top cover. The front cover of the transmission is specific to the 16 x 8 transmission because of the addition of the hydraulic clutch for the DualPower™ ranges. The front cover incorporates two modulation pistons which help to enable the change between standard range and DualPower™ ranges. Additionally, the front cover incorporates the DualPower™ solenoid as well as the valves for modulation of the change between forward and reverse.

Power Shuttle valve The Power Shuttle transmissions use an forward/reverse control valve, which is comprised of two sections. The upper section of the valve incorporates the system pressure-regulating valve, which maintains system pressure at 1503 1800 kPa (218 - 261 psi). The upper section also includes the port to the oil cooler, the cooler by-pass valves, and the lubrication pressure relief valve. The front part of this section includes a pressure sensor, which sends a signal to the instrument cluster. The lower section of the Power Shuttle valve contains two spools. One of the spools is shifted by the forward/neutral/reverse lever on the left-hand side of the steering wheel. The other spool activates by the movement of the inch pedal (clutch pedal) and serves to enable gear changes.

Transmission - Mechanical transmission

Mechanical transmission - Static description The 8x8 transmission The 8x8 transmission offers 8 forward and 8 reverse gears which are selected by means of 3 levers. Normally the standard version is 30 km/h with the option of 40 km/h The transmission offers two ranges from which to choose. Within the two ranges, four synchronized gears are available, which provides 8 gears. The two gear change levers allow the selection of the 8 gears. The primary shift lever moves in the conventional “H” pattern. Press the clutch pedal to enable gear changes in the synchronized gearbox. The range shifter must be used with the clutch pedal in order to select one of the two ranges. The reverser lever is located on the left-hand side of steering column. The reverser lever permits the selection of F or R travel. The 8 x 8 mechanical transmissions require that the clutch pedal be pressed to change directions.

NHPH11TR00056AA

NHIL12TR00056AA

The standard constant mesh transmission contains eight forward gears and eight reverse gears. The main shift lever (front and longer lever) operates in the pattern shown, which allows you to select one of four forward or reverse gears. The range lever (lever to the left-hand side of the main lever) allows the selection of high (H) or low (L) and produces twice the available gears. Stop the machine and fully depress the clutch before moving either of the levers. The shift pattern is explained in the image on the right. NOTE: A neutral safety switch prevents the operation of the starter motor unless the range lever is in the neutral (N) position.

Creeper (optional) Tractor transmissions equipped with the optional creeper function has a reduction gear box, with a reduction ratio of 10:1. The creeper reduction gear is incorporated in the range lever (Creeper – Low – Neutral – High). NOTICE: to prevent problems at start up, do not turn the engine off with the creeper gear engaged. When starting the engine, the Range lever must be in the neutral (N) position. If the machine is shut down with the creeper gear engaged, it may not be possible to move the lever into neutral (N).

Four-Wheel Drive (4WD) system - Electrohydraulic control

Front-Wheel Drive (FWD) clutch - Overview The Fourâ&#x20AC;&#x201C;Wheel Drive (4WD) clutch is spring applied and hydraulically released. The 4WD is engaged by the switch located on the right hand side of the instrument cluster or by the brake switches, which operate when the brake pedal is pressed. The switches break the circuit and de-energize the 4WD solenoid. Pressurized oil flow into the 4WD chamber (4) is controlled by an electrical solenoid and a sliding lead-in valve (3), (9) equipped with a spring loaded check valve. The valve is placed in the central oil passageway of the shaft. When the solenoid is energized, oil flows to the lead in valve via the oil transfer tube (2) causing the complete lead in valve to move forward (toward the engine). Once the lead in valve has moved forward, the pressurized oil passes through the valve center and lifts the ball from its seat, allowing pressurized oil to reach the chamber (4). This forward motion seals the passage way and closes off the oil return ports (8) thus sealing the chamber. Oil pressurizes the chamber and moves the friction clutch (7) against the engagement springs (5),and separates the friction clutch gear trigger teeth from the driven gear teeth (1). When the solenoid is de-energized, the hydraulic pressure is removed or lessened in the oil transfer tube. The reduced pressure allows the spring pressure to force the friction clutch towards the driven gear. Since the hydraulic pressure is now greater in the chamber than in the oil transfer tube, the lead in valve and check valve now move towards the rear of the 4WD drop box. This movement exposes the oil outlets in the chamber and allows the oil to return to sump. Once the spring pressure is sufficient to overcome the hydraulic oil pressure, the gears engage and the 4WD engages. NOTE: There is always a small amount of leakage at the lead in valve to avoid a hydraulic lock condition when the solenoid is de-energized.

Four-Wheel Drive (4WD) system - Four-Wheel Drive (4WD) gearbox

Gearbox - Overview All of the Four-Wheel Drive (4WD) gear boxes are identical, with the exception of the gear ratios. The different gear ratios are necessary to accommodate different front and rear tire sizes. The gearbox gear ratio is stamped on the front side of the case, under the output shaft. The gear box includes a jaw clutch which connects the driven gear to the output shaft. The clutch is spring applied and hydraulically released. This clutch activates when the hydraulic pressure from the low pressure circuit is removed and the 4 springs engage the 4WD clutch. A helicoidal gear installed on the drive pinion shaft of the rear axle transfers drive to an intermediate gear supported by two tapered roller bearings in the gear box. The intermediate gear drives the output shaft gear. The output shaft is supported by two tapered roller bearings. The driven gear turns freely on the output shaft. The jaw coupler is splined onto the output shaft and when the clutch is engaged, the jaw coupler and the driven gear are coupled. Gear ratios in the gear box are determined by the number of teeth of the lower, output shaft gear. An electro-hydraulic valve sends hydraulic oil from the DualPowerâ&#x201E;˘ and the independent Power Take-Off (PTO) circuits, through an external tube, to the rear plate of the gear box. When the solenoid is energized, oil passes through the transfer tube to the output shaft bore. The pressurized oil disengages the 4WD clutch.

Measure the backlash between the pinion and ring gear with a dial indicator.

Measure the backlash at two other positions separated by 120 °. Compare the measurements and take an average. The average of the three measurements (GM) should be between 0.15 - 0.20 mm (0.006 - 0.008 in). If the play exceeds the specification, install a thinner shim. Use the following equation to calculate the shim thickness to install. Shim (S) = SP - ((GM - 0.18) x 1.35) SP = The thickness of the installed shim or the thickness of the original shim. GM = The average backlash measured between the ring gear and pinion. If the play is less than the specification, install a thicker shim. Use the following equation to calculate the shim thickness to install. Shim (S) = SP - ((GM - 0.18) x 1.35) SP = The thickness of the installed shim or the thickness of the original shim. GM = The average backlash measured between the ring gear and pinion. Verify the backlash after installing the shim and change the shim thickness as necessary.

Differential bearing preload The differential bearing preload is measured by measuring the combination of the rolling torque of both the pinion shaft and the ring gear, and comparing it to the rolling torque of the pinion shaft with the seals installed. 1.

Use a torque wrench to measure the rolling torque of the ring and pinion (A2).

Subtract the rolling torque (A2) from the rolling torque measured for the pinion shaft (A1). The difference between the measurements should be between 1 - 1.5 N·m (0.7 - 1.1 lb ft).

If the rolling torque is not within specification, adjust the ring opposite the ring gear to increase or decrease the rolling torque. Measure the rolling torque again using the same method. Example: A2 = Rolling torque of pinion and ring gear A1 = Rolling torque of the pinion shaft A2 - A1 = Rolling torque of differential bearings. NHIL12TR00341AA

Powered front axle - Overview TS6.110, TS6.110 HC, TS6.120, TS6.120 HC

Four-Wheel Drive (4WD) front axle description and operation The Carraro front axle is identified by a nameplate placed on the back of the right-hand axle housing. The nameplate also has a series number and a reference number for gear ratios, oil capacity, and type of grease. When ordering parts, always indicate the type, reference, and series number. See NEW HOLLAND AGRICULTURE specifications for oil and grease requirements. Axles pivot in the center to allow articulation when driving on uneven terrains, and the drive axle or drive pinion passes through the hollow center at the back of the pivot. This layout supports the drive axle by connecting the front axle to the 4WD transfer box in a straight line in any type of articulation. A universal joint at each end of the driveshaft connects the shaft to the axle and gearbox. Final gear reduction is achieved through three epicyclic gears in the final drive hub. The hubs pivot by means of upper and lower bearing sets, which can be lubricated and replaced to increase durability. The axle has a centrally mounted differential, which is supported by replaceable bearings. The differential is limited slip. The action of the limited slip differential is achieved by means of multidisc clutches placed on each side of side differential gears. When one of the two front wheels loses traction, torque response on the differential exerts an axial force through the side gears, pressurizing clutch discs. Externally splined discs are connected to the differential casing and the internally splined discs are connected to the side gears. When the torque increases, it is difficult for friction surfaces to move independently. Thus, the side gears remain connected to the casing, which causes a differential lock. As soon as the tendency to slide disappears, the torque response decreases, and the system unlocks automatically. Each axle has a removable steering cylinder attached to the differential support. The cylinder attaches to the differential support and the hub swivel with ball joints. With the exception of the differential; the reduction hubs, hub bearings, axle shafts, and steering cylinders can be disassembled without the removal of the front axle assembly..

Shims between the drive pinion and its head shaft 1.

Determine if a new thickness of the shim between the drive pinion and its head shaft is required. •

If you will reinstall the existing pinion and crown, the pinion bearings and the differential housing support, you do not have to recalculate the shim thickness and you can reinstall the existing shims. Skip to ' 9 through 15, “Assembly of pinion internal bearing”.

•

If you replaced the pinion and crown, the pinion bearings and/or the differential housing support, you must recalculate the thickness of the shim placed behind drive pinion head in its shaft. Continue with the steps that follow to calculate shim thickness.

Install pinion bearings (1) in the differential housing support and fix them using a pinion adjustment tool (2). Make sure the disc of the pinion adjustment tool has the side with the trim pointing upwards. Tighten the pinion adjustment tool until the bearing cones can be turned manually. Do not overtighten.

Install the side bearing covers of the differential housing support (not the bearing tracks) and tighten the cover nuts to specification.

Measure the housing of the side bearing, as shown. Record this measurement as value 'A'.

Installation of bolt and lower caliper 1.

Carefully mount the hub and knuckle housing on shaft and its housing on the flared tube. Make sure the shaft does not damage the detent when passing through the housing, nor damages the detents of the upper and lower reciprocating bolts.

NOTE: Reciprocating bolt bearings are preloaded at 0.20 - 0.40 mm (0.008 - 0.016 in). Preload should be adjusted when installing new bearings or a new casing. When installing a new bearing, it is advisable to adjust preload to its upper limit, and when installing worn bearings, adjust preload to its lower limit. 2.

Select the 10 mm (0.4 in) shim (2) and mount the lower reciprocating bolt (1) with this shim below the bolt head.

Without installing shims, mount the upper knuckle bearing. Tighten the upper and lower knuckle bearings to specified torque.

Mount a gauge with the end on the upper part of the upper knuckle bolt and with the body fixed to the tube as shown.

Place the dial to zero and pry up the knuckle housing. With the 10 mm (0.4 in) shim in lower bolt, a certain free play is achieved. Record the free play. 47377790 31/10/2012

Add the specified preload to the registered measurement and subtract the already mounted shim total of 10 mm (0.4 in). The result will be the total thickness to achieve specified preload. The result of this thickness should then be divided into two equal parts to distribute between upper and lower bolt. Refer to the equation and the example that follows to determine the spacer. S = [C - (A + B)]/2, where S = Shim to be placed on each pivot cone. C = Shim or benchmark of 10 mm (0.4 in) A = Measured or registered free play on the gauge B = Specified preload range 0.20 - 0.40 mm (0.008 - 0.016 in). When installing a new bearing, it is advisable to adjust preload to its upper limit, and when installing worn bearings, adjust preload to its lower limit. Example (in mm): S=? C = 1.0 A = 0.20 measured free play B = 0.40 for new bearings S = [1.0 - (0.20 + 0.40)]/2 S = 0.40/2 S = 0.20 mm for each bolt

Remove the reciprocating bolts (1), figure 1, and the 1.0 mm (0.04 in) shim (2) figure 1, of the lower bolt.

Rear axle system - Powered rear axle

Powered rear axle - Component identification Description and operation There are two rear axles available. The standard rear axle uses three planetary gears in the final drive and is available on the TS6.110 and TS6.120. The heavy-duty rear axle uses four planetary gears and is available on the TS6.125 and TS6.140. Both rear axles have an electrohydraulic differential lock and hydraulic brakes. The rear axle, mounted on the rear of the transmission, connects the power from the engine and the transmission to the rear wheels. The following components are contained within the rear axle: • Ring and pinion of the differential • Differential • Electrohydraulic ifferential lock • Hydraulic brakes • Final reduction gears • Wheel axle shafts • Power Take-Off (PTO) components • Park/hand brake • Fixed displacement hydraulic pumps The power from the output shaft of the transmission passes through the spiral teeth of pinion by means of a coupler. The pinion is in the front part of the rear axle housing. The pinion is mounted in two, preloaded, cone and cup bearings and contacts the ring gear of the differential. The ring gear is riveted to the differential carrier, which is supported between tapered roller bearings mounted in the rear axle housings. NOTE: In service, bolts and nuts replace the rivets.

Rear axle - Component identification • There is a thrust block mounted on the axle to keep the ring gear from flexing during drive pinion preload. The thrust block also ensures that some lubricating oil passes through to the drive pinion bearings. • The axle shaft housings receive a larger amount of oil than the center housing. The left hand (1) and the right hand (2) axle housing have restrictions (3) to maintain the higher levels.

Example: Left hand oil restrictor (1) Rear axle center housing (2) Plastic plug

• The differential case assembly forms two halves which bolt together to enclose the differential crosshead and the side gears. • The drive from the pinion transmits through the ring gear and the differential cases assembly to the crosshead. Pinion gears mounted on the crosshead are in constant mesh with the side gears. • The brake assemblies mount on the spline end of the intermediate shafts. The intermediate shafts spline into the side gears. • The outer end of each intermediate gear forms the sun gear of an epicyclic final reduction gear set and is mounted within the axle housings. • A reduction gear set transmits drive to the wheels from the intermediate shaft to the axle shaft. • The side gear carrier mounts to the inner spline of the exterior axle shaft. Tapered roller bearings, which are installed in each axle housing, support the axle shafts. • The hydraulic system oil lubricates the rear axle components. The differential ring gear assembly is partially submerged in oil to provide splash feed lubrication to the bearings and bushings.

Differential lock - Overview The machines are equipped with a differential lock system to help prevent wheel slippage and loss of traction. For example, if working on soft terrain and one of the wheels loses traction, all of the force is transferred to that wheel, and the machine does not move. The differential lock assembly is installed on the left-hand side of the ring gear and overcomes machine wheel slippage by connecting one of the side gears to the differential case assembly. When the differential lock is engaged, both of the rear axles are locked together and function as if they were on a common shaft. The differential lock is made up of: • A sliding coupling (3) connected to the spline of the side gear. • An adaptor (2) positioned between the coupling and the left hand differential case (1). • A spring (4) positioned between the coupling and the adapter. The spring ensures the coupling only engages the adaptor when necessary and that the differential lock disengages when it is no longer necessary. • A fork and lever assembly (not shown). An electro-hydraulic valve pushes on a push rod, which pushes the fork and the lever. When the fork moves, it forces the coupling trigger teeth into the adaptor, which locks the differential.

RCPH09TTS398AAD

The mechanical differential lock is automatically disconnected when the pressure from the spring rises above the lateral force from the coupling teeth. This happens when the torque is equal in both wheels. NOTICE: Avoid using the differential lock at speeds greater than 8 km/h (5 mph) or when the machine is turning. Engaging the lock causes problems in machine's steering. NOTICE: To prevent transmission damage, reduce the engine speed before engaging the differential lock.

Rear axle system - Planetary and final drives

Planetary final drive - Overview In order to increase the torque transmitted to the rear wheels, there is a set of epicyclic reduction gears is in each rear axle housing. The end of each intermediate shaft functions as a planetary sun gear around which there are three side gears. The side gears are mounted onto a support that is splined to the rear axle. The side gears mesh with a ring gear that is mounted on the axle housing. When the intermediate shaft turns, the side gears turn around the inside of the fixed ring gear. This action makes the planetary sun gear turn and reduces the speed, which transmits more torque to the rear axle and wheels.

Power Take-Off (PTO) - Two-speed rear Power Take-Off (PTO)

Description and operation The Power Take-Off (PTO) enables the transfer of engine power directly to mounted or trailed equipment through an output shaft at the rear of the tractor. The output shaft speed is restricted to 540 RPM for equipment designed for use with the six-spline shaft, and 1000 RPM for equipment designed for the alternate twenty one -spline shaft. The PTO input shaft passes through the transmission upper shafts, and attaches to both the engine flywheel and the PTO clutch hub with spline ends. The speed of the output shaft is independent of the transmission or tractor ground speed, but directly related to the speed of the engine. During engagement of the PTO, a hydraulically operated piston clamps the friction and steel drive plates together, thereby transmitting drive from the flywheel to the PTO output shaft. A valve assembly located in the left-hand side of the rear axle housing controls hydraulic oil to the clutch piston. The control valve spool features a hydraulic feathering capability, which allows for the smooth engagement of the PTO clutch. A brake band applied by a small hydraulic actuator holds the clutch housing stationary upon disengagement. NOTE: The PTO output shaft will rotate by hand to facilitate attachment of equipment. The tractor incorporates one of two types of PTO systems as follows: â&#x20AC;˘ Single Speed PTO - Operates the standard six -spline output shaft, which rotates at 540 RPM with engine speed at 1900 RPM. â&#x20AC;˘ Two-Speed PTO (Non shiftable), operates either the six -spline shaft at 540 RPM, or the twenty one - spline shaft at 1000 RPM, with engine speed at 2060 RPM.

It is possible to engage, operate and disengage the PTO system with the tractor in motion. The clutch for single speed PTO systems operates mechanically or electrically.

SHG31008

Mechanical operation NOTICE: Never operate the tractor with the PTO output shaft removed. The shaft supports the driven gears and acts as a bearing. Operation without the shaft installed may cause severe damage. A selector lever located on the left-hand side of the driver s seat provides formechanical operation of the PTOclutch, and control valve. Operating the selector lever moves linkage to the control valve spool to the “engage” or “disengage” position.

Oil flow - clutch disengaged (Refer to Figure 4). With the engine operating, the rear steering pump supplies hydraulic oil to the inlet port of the PTO control valve. The pressure regulating valve housed within the PTO assembly maintains the oil pressure at engine speed of 800 RPM to 896 - 1103 kPa (130 - 160 psi). When engine speed increases to 2100 RPM the oil pressure increases to 1172 - 1379 kPa (170 - 200 psi). In addition, the oil pressure regulating valve directs lubricating oil to the PTO clutch and DualPower™ circuits. A relief valve in the lubricating circuit restricts oil pressure to a maximum of 345 kPa (50 psi). Refer to the “Hydraulics” section 35 for a detailed description of the lubricating oil circuit. Under normal operation, the pressure regulating valve remains in the closed position. Moving the selector lever full rearward (disengage position) mechanically pulls the control valve spool to the left. The center land area of the spool opens an orifice, which allows low-pressure circuit oil to flow past the spool and enter the brake cylinder through a drilled passage. Oil pressure acting on the brake piston tightens the brake band, which prevents the PTO output shaft from turning. A spring ball and detent lock the spool to the full left side.

Power Take-Off (PTO) - Two-speed rear Power Take-Off (PTO)

Oil Flow - clutch engaged (Refer to Figure 5). The control valve spool consists of two parts connected by a link and spring, which enables feathering of clutch engagement. Initial movement of the selector lever to the forward (engage position) mechanically moves the control valve spool to the right. The center landed area of the spool blocks an orifice that receives oil supplied by the pump to the brake piston, and opens a return port for the brake and clutch piston oil to exhaust. Continued movement of the selector lever forward mechanically moves the spool further to the right until uncovering the supply oil orifice, allowing oil pressure to cross the spool and reach the clutch piston. Oil pressure acting on the clutch piston, forces the piston against the clutch return spring, causing system pressure to increase. Through a small drilling in the center land area of the spool, supply oil pressure reaches the right side of the spool. Oil pressure builds and acts on the spool, forcing the spool to the left and compressing the spring between the two halves of the spool. As the spool moves left, oil from the supply orifice is now blocked. This restriction of oil flow ensures a feathering of clutch engagement in relation to the movement of the selector lever. With the selector lever full forward (engage position), a spring ball and detent holds the spool in place at the full right position. Pressurized oil acting on the clutch piston compresses the clutch return spring, and forces the clutch plates together for clutch engagement. Due to the locked condition of the spool, feathering is no longer possible and clutch engagement receives maximum pressure. The pressure regulating valve continues to maintain oil pressure during clutch engagement. In preventing a subsequent shock load to the system, the small supply oil orifice restricts the rate of oil flow to the clutch when rapid movement of the selector lever occurs.

Brakes and controls - Hydraulic service brakes

Hydraulic service brakes - Dynamic description Rear brake assembly The brake discs are located in both axle housings and are immersed in oil. The TS6.125/TS6.140 tractors use a hydraulic brake system that has four friction discs installed in each axle housing of the heavy-duty rear axle. Four brake discs are also installed on machines that have the 40 km/h (25 mph) transmission. The TS6.110/TS6.120 tractors use three friction discs in each axle housing when paired with the 30 km/h (19 mph) transmission. The brake consists of the splined brake discs, separator discs, and an actuator in axle housing. The actuator consists of two discs with ramps and balls. The discs are held together with springs and are connected to the brake linkage with two links. A hydraulic slave cylinder activates the brake linkage. When the brake pedal is pressed, the actuator discs move apart from one another as the balls roll up the ramps. As the actuator discs move apart, the friction discs are pushed against the brake housing which slows the axle shaft. A common reservoir contains the brake fluid which is supplied to both of the master cylinders. There is a master cylinder attached to each brake pedal. There is a union tube between the master cylinders that contains a compensating valve that equalizes pressure to the brake actuators in the axle housings. The compensating valve helps the system accommodate variances in wear and adjustment between the two sets of brake discs.

Hydraulic service brakes - Static description â&#x20AC;&#x201C; Four wheel braking Four wheel braking is available on all Four-Wheel Drive (4WD) models. Four wheel braking activates by means of the brake switches when both pedals are pushed. Pressing both pedals interrupts the current to the 4WD solenoid that causes the 4WD to engage. NOTICE: Avoid serious damage to the gear teeth of the 4WD gearbox by ensuring that the brake switches are well adjusted, so that the 4WD is engaged before the brakes are activated in the rear axle.

Hydraulic systems - Overview The hydraulic system provides oil flow at regulated pressures for the operation and lubrication of various circuits within the tractor, as well as providing accurate and sensitivity control of implements over a wide range of operating conditions. The standard hydraulic system consists of a top link sensing and three-point linkage system, a fixed displacement tandem (gear type) main pump, an engine mounted auxiliary pump (optional), lift cylinder assembly, and remote control valve(s). The rear axle center casing functions as the hydraulic system reservoir. A lift control valve, and priority valve pack containing several valves, function together to direct the hydraulic oil as needed. A pressure regulator, and various relief and check valves protect the circuits and components from overload conditions, encountered during normal and arduous operation. The configuration and combination of valves prevents oil back flow. The hydraulic system consists of two major circuits: â&#x20AC;˘ High Pressure Circuit (includes optional engine mounted auxiliary pump if equipped) â&#x20AC;˘ Low Pressure, Steering and Lubrication Circuit

Hydraulic systems - Detailed view High pressure hydraulic pump circuit Operating with a maximum pressure of 182 bar (2639 psi), the high-pressure circuit supplies oil for control of the hydraulic lift assembly, remote control valve(s), and auxiliary equipment (where installed). With more than two remote valves installed on the tractor, it is necessary to supplement the tandem (gear type) transmission mounted pump output, with an engine mounted auxiliary pump. The front pump within the tandem pump assembly circulates pressurized hydraulic oil to the priority valve group. A relief valve installed in the pump protects the circuit from overload, with an operating pressure of 176 - 182 bar (2552 - 2639 psi). The oil supply from the tandem pump flows to the priority valve group through internal galleries within the hydraulic top cover, while the supply from the optional auxiliary pump flows to the priority valve group through external tubing. – Pump pressurized oil

Low pressure hydraulic pump circuit The low-pressure circuits perform two major functions. They supply pressurized hydraulic oil for the operation of the steering system, Four–Wheel Drive (4WD) clutch, hydraulic Power Take-Off (PTO) clutch, PTO brake, and DualPower™ assembly. The low pressure circuits supply lubricating oil to the hydraulic PTO clutch, DualPower™ assembly , and the transmission. Before entering the transmission, lubricating oil passes through an oil cooler mounted in front of the radiator. This is an open center system. The low-pressure and lubrication circuits provide a continuous flow of hydraulic oil throughout the system. The rear pump within the tandem gear pump assembly circulates pressurized hydraulic oil through tubing to the steering motor, hydraulic PTO clutch control valve, and to the DualPower™ clutch control valve within the transmission housing. A pressure regulating valve in the hydraulic PTO clutch assembly controls oil flow to the lubricating and cooling circuit. In addition, excessive oil in the lubrication circuit discharges to sump through an adjacent relief valve. The relief valve protects the circuit from overloading with a minimum operating pressure of 5.3 bar (76.9 psi). – Pump pressurized oil

Oil flow neutral â&#x20AC;&#x201C; inching spool engagement

NHIL12TR00227AA

NHIL12TR00228AA

The pressure control valve, in the lubrication oil distribution block, limits the pressure in the low pressure hydraulic circuit to 1499.6 - 1899.5 kPa (217.5 - 275.5 psi) and any excess flow discharged from the pressure control valve is ported into the lubrication oil circuit.

NHIL12TR00229AA

The pressure regulator is the mechanism that ensures the proper pressure modulation of the transmission oil through the clutch output ports. This occurs when shifting from neutral to the forward or reverse position (while NOT operating the inching spool).

By releasing the clutch pedal, the clutch inching spool is pushed in, and as a result, the springs on inching spools are progressively loaded to modulate output clutch pressure.

NHIL12TR00231AA

The shuttle spool, when in the neutral position, ports both the forward and reverse clutches to the hydraulic tank. The shuttle spool is connected to a three position lever mechanism installed on the steering column of tractor.

Shuttle spool forward and reverse engagement. The inching spool is connected to the clutch pedal via a cable. When the clutch pedal is depressed, the clutch inching spool is pulled outwards. During the initial stroke, the springs on the inching spools are progressively released to reduce the controlled pressure from maximum nominal pressure to nearly tank pressure. In the last section of the stroke range, both directional ports on the inching spool are mechanically linked in order to fully port to tank the forward or reverse clutch output. This ensures that clutch output pressure is reduced to tank pressure. This ensures that when the clutch pedal is depressed (inching spool fully extended), shifting the shuttle spool into forward or reverse position will not result in gear engagement. By releasing the clutch pedal, the clutch inching spool is pushed in, and as a result, the springs on inching spools are progressively loaded to modulate output clutch pressure. Forward or reverse clutch engagement can be interrupted and then resumed at any time by depressing the clutch edal for fine-metering inching control.

Hydraulic systems - Hydraulic standard Accurate diagrams of hydraulic circuits are essential to the technician who must repair them. The diagram shows how the components interact. The diagram shows how the system works, what each component should be doing and where the oil should be going so the technician can diagnose and repair the system. There are two types of circuit diagrams: • Cutaway circuit diagrams show the internal construction of the components as well as the flow paths. Using colors, shades or various patterns in the lines and passages, they show many different conditions of flow and pressure. Cutaway diagrams take considerably longer to produce because of their complexity. • Schematic circuit diagrams, the “shorthand” system of the industry, are usually preferred for troubleshooting. A schematic diagram is made up of simple geometric symbols for the components and their controls and connections. There are several systems of symbols used when making schematic diagrams: • ISO – International Standards Organization • ANSI – American National Standards Institute • ASA – American Standards Association • JIC – Joint Industry Conference A combination of symbols from these systems are shown. There are differences between the symbol systems. There is enough similarity, however, so if you understand the symbols shown, you will be able to interpret other symbols as well.

Reservoirs A rectangle with the top removed represents a vented reservoir (A). A rectangle with the top in place represents a pressurized reservoir (B).

RCIL07CCH027AAA

RCIL07CCH030AAA

RCIL07CCH032AAA

There are other schematic diagrams that show a slightly different version of a pressurized reservoir, but the symbols are similar and easily recognized. An oval with a short line on top or a rectangle with curved sides represents a reservoir that is pressurized.

Lines connected to the reservoir usually are drawn from the top, regardless of where the actual connection is. This symbol shows a line which returns fluid above the level in the reservoir.

If the hydraulic line returns fluid below the level in the reservoir, it is drawn all the way to the bottom of the symbol.

If the pump inlet (B) must be charged or flooded with fluid above the inlet port, the reservoir symbol (A) appears above the pump symbol, and the suction line is drawn out of the bottom of the reservoir symbol. Every system reservoir has at least two hydraulic lines connected to it, and some may have many more. Often the components that are connected to the reservoir are spread all over the schematic. Rather than multiplying lines all over the schematic, individual reservoir symbols are drawn close to the components. The reservoir is usually the only component symbol pictured more than once on a diagram.

Lines, tubes and hoses A hydraulic line, tube, hose or any conductor that carries the fluid between components is shown as a line. A working line, such as an inlet pressure or return, is shown as a solid line.

Working lines with arrows show direction of flow. In the first example (A), fluid flows in one direction only; in the second example (B), fluid can flow in both directions.

Pilot or control lines (A) are broken into long dashes. Drain lines (B) for leakage oil are broken into short dashes.

A flexible line is shown as an arc between two dots and is always represented by a solid line.

Lines between components are drawn differently when they are crossing or connected. There are lines that cross other lines but are not connected. There are several ways to show crossing lines which are not connected.

Lines that are connected are shown with a dot that represents the connection or shown as a tee connection. The dot connection is the most commonly used when drawing schematic diagrams.

Pumps There are many basic pump designs. A simple fixed displacement pump (A) is shown as a circle with a solid arrow that pointing outward. The arrow points in the direction that the fluid flows. If the pump is reversible (B) or designed to pump in either direction, the symbol has two arrows which point in opposite directions. The pump normally has a pressure port and line (1) from which pressurized fluid is discharged and a suction port and line (2) into which fluid is drawn from the reservoir.

A variable displacement pump (A) is shown by an arrow drawn through the pump symbol at a 45 degree angle. A variable displacement, pressure compensated pump (B) is shown by a small box with an arrow, added to the side of the pump symbol.

If the pump is controlled by a lever (A) or a pedal (B), the appropriate symbol is added to the side of the pump.

Motors Motor symbols are circles with solid black arrows, which point in the opposite direction of a pumpâ&#x20AC;&#x2122;s arrow, to show the motor as a receiver of fluid. One arrow is used for non-reversible motors (A); and two arrows are used for reversible motors (B).

A simple schematic diagram is shown of a hydraulic motor (A) connected to a hydraulic pump (B).

Cylinders A cylinder is a simple rectangle (A) representing the barrel. The piston and rod are represented by a tee (B), inserted into the rectangle. The symbol can be drawn in any position.

A double rod end cylinder has a rod extending from each end of the rectangle.

Some cylinders have cushions built into them. The cushion slows the movement of the piston as it nears the end of its stroke. Cylinder cushions are shown as a smaller rectangle (A) on the piston. If the cushion has an adjustable orifice, a slanted arrow is drawn at 45 degrees (B) across the symbol.

Accessories Filters, strainers and heat exchangers are represented as squares that are turned 45 degrees and have the port connections at the corners. A dotted line perpendicular to the flow line represent a filter, strainer or screen.

The symbol for a heater is like the symbol for a cooler, except the solid arrows point inward.

Two sets of arrows pointing inward and outward represents a temperature control unit The solid arrows point in the direction that heat is dissipated. Or in the case of the control unit, they show that heat can be regulated.

An oval with details inside represents an accumulator. The details explain what type of accumulator it is: spring loaded (A), gas charged (B), or other features. The divider line indicates there is a separator between the charge and the fluid. A hollow arrow indicates gas. A spring indicates that the accumulator is spring-loaded.

Hydraulic systems - Pump control valves

Pump control valves - Dynamic description Control valve oil flow – Neutral With the control valve in the neutral position, the following functions occurs: • The trapped hydraulic oil within the lift cylinder holds the cylinder in the desired position. • Pressurized oil enters the combining valve, located in the priority valve pack on top of the hydraulic lift cover. The combining valve either returns the oil to the reservoir, or directs it to the remote valve(s), depending on demand. • Hydraulic circuits without remote valves installed, do not require a combining valve. With the control valve in the neutral position, the following oil flow occurs: • Pump pressure enters the lift cover at Gallery E, where the control valve prevents the oil from entering Galleries C and D. • Pressurized oil flows up Gallery E to the flow control valve and unload valve. • The unload valve opens to return at the left side via Gallery C, and the control valve center. • Oil pressure applied to the center face of the spool in the unload valve holds the spool to the left. • With the unload valve held to the left, oil in Gallery D, and in the spring-loaded end of the flow control valve, returns to sump through Gallery G, by way of a small internal drilling in the unload valve. • Oil pressure in Gallery E now acts on the right-hand face of the flow control valve via an internal drilling, and moves the valve full left, which allows the oil to flow from Gallery E to Gallery F. • With the remote valve(s) in neutral, the load sensing, line pressure vents to sump through the remote valve(s). Pressurized oil in Gallery F acts on the right-hand side of the combining valve, and moves the valve to the left, which ports oil from Gallery F to return through Gallery G. • The oil in the lift cylinder remains trapped in Galleries A and B by the control valve land, and the check valve. – Pump pressurized oil – Trapped oil – Suction oil / return to deposit – Auxiliary pump oil (if equipped) (1) (2) (3) (4) (5) (6)

Control valve oil flow – Lowering position With the control valve in the lowering position, the following functions occurs: • Pressurized oil enters the combining valve, located in the priority valve pack on top of the hydraulic lift cover. The combining valve either returns the oil to the reservoir, or directs it to the remote valve(s), depending on demand. • Hydraulic oil within the lift cylinder returns to sump through the control valve and exhaust valve. With the control valve in the lowering position, the following oil flow occurs: • Pump pressure enters the lift cover at Gallery E, where the control valve prevents the oil from entering Galleries C and D. • Pressurized oil flows up Gallery E to the flow control valve and unload valve. • The unload valve opens to sump on the left side via Gallery C, and the control valve center. • Oil pressure applied to the center face of the spool forces the spool to the left. • With the unload valve held to the left, oil in Gallery D, and in the spring-loaded end of the flow control valve, returns to sump through Gallery G, by way of a small internal drilling. • Oil pressure in Gallery E acts on the right-hand face of the flow control valve via an internal drilling, which moves the valve full left, allowing the oil to flow from Gallery E to Gallery F. • In both the neutral and lowering positions, a lack of demand from the remote valve(s) will cause the combining valve to discharge hydraulic oil back to sump. • As the control valve moves to the right from neutral to the lowering position, lift cylinder oil flows out of Galleries A and B, through the control valve, and on to sump through the exhaust valve. • Excess oil flow from the lift cylinder through the exhaust valve forces the valve down against the spring, which reduces the exhaust port aperture.The reduced exhaust port aperture consequently controls the lowering of the lift arms irrespective of the loading on the lift linkage. – Pump pressurized oil – Trapped oil – Suction oil / return to deposit – Auxiliary pump oil (if equipped) (1) (2) (3) (4) (5) (6)

Hydraulic systems - Pump control valves

Control valve oil flow – Raise position (slow) When raising the hydraulic lift, two conditions occur, referenced as slow and fast raises. The number of open ports in the control valve that direct pressurized oil to the lift cylinder determines the speed of the lift. Moving the lift control lever to the point where the hydraulic lift begins to raise, engages the slow lift and the following functions occur: • Pressurized oil flows to the lift cylinder or combining valve. • The position of the control valve determines the position of the flow control valve, giving priority to lift cylinder demand, and diverting the surplus oil to the combining valve. • The combining valve either returns the surplus oil to the reservoir, or directs it to the remote valve(s), depending on demand. With the control valve in the slow raise position, the following oil flow occurs: • The initial movement of the lift control lever shifts the control valve from the neutral to the slow raise position. This allows pressurized oil from Gallery E to flow to Gallery C through a drilled passage in the control valve, and the left-hand end of the unload valve. • The combination of spring pressure in the unload valve, and oil pressure in Gallery C, shifts the unload valve spool full right, connecting Galleries E and D through a large cross drilling. • The channel drilled in the unload valve restricts the hydraulic oil flow to 7.6 l/min (2.0 US gpm), which induces a smooth initial lift. The reduced pressure acts on the left-hand face of the flow control valve spool, and moves it to the right. The initial oil flow from the flow control valve enters Galleries A and B through a check valve. • Further movement of the control valve to the left, uncovers a series of ports connecting Gallery E with Gallery D. Oil flow increases into Gallery D, which speeds up the lift cylinder movement. The flow control valve moves further to the right, reducing oil flow from Gallery E to Gallery F. – Pump pressurized oil – Trapped oil – Suction oil / return to deposit – Auxiliary pump oil (if equipped) (1) (2) (3) (4) (5) (6)

Control valve oil flow – Raise position (fast) When raising the hydraulic lift, two conditions occur, referenced as slow and fast raises. The number of open ports in the control valve that direct pressurized oil to the lift cylinder determines the speed of the lift. Moving the lift control lever fully backward engages the fast lift position bypassing the slow lift, and the following functions occur: • The flow control valve gives full priority to the lift cylinder. • At this point, operation of the remote valve(s) would only be possible with an additional auxiliary engine mounted pump installed. With the control valve in the fast raise position, the following oil flow occurs: • The full rear movement of the lift control lever shifts the control valve pass the slow raise position to the fast raise position. All the ports in the control valve bushing uncover, allowing increased pump oil flow from Gallery E to Gallery D. • The combination of spring pressure in the unload valve, and oil pressure in Gallery C, shifts the unload valve spool full right, connecting Galleries E and D through a large cross drilling. • Oil flows from Gallery E to Gallery D with less restriction and the pressure on both sides of the flow control valve equalizes. The flow control vale spring moves the spool to the full right position, closing off Gallery E from Gallery F. • All pressurized oil from the pump diverts to the lift cylinder through Gallery A, giving the lift cylinder priority over the remote valve(s). • The size of the ports in the flow control valve bushing limit the oil flow to the lift cylinder to a maximum of 31.0 l/min (8.2 US gpm). • The completely closed off Gallery F allows the combining valve to move to the right, preventing oil flow to sump through Gallery G, unless there is an auxiliary engine mounted pump installed. – Pump pressurized oil – Auxiliary pump oil (if equipped) – Suction oil / return to deposit (1) (2) (3) (4) (5) (6)

Hydraulic systems - Pump control valves

Control valve oil flow with auxiliary engine mounted pump (if equipped) The optional auxiliary engine mounted pump supplements pressurized oil to the remote valve(s) circuit. • A pilot (load sensing) signal applied to the left end of the combining valve moves the valve to the right. This blocks the connections of Gallery F to G and Gallery H to G progressively, depending on the hydraulic requirements of the remote valve(s). • Pressurized oil from the auxiliary pump enters the priority valve pack and forces open the remote valve feed checkvalve open to combine with oil flow from the main pump in Gallery F. • With the remote valve(s) circuit in neutral, the load sensing line vents, and pump oil pressure in Gallery F moves the combining valve to the left, opening pump oil flow to return through Gallery G. • The relief valve within the combining valve vents oil to return through Gallery G, if pressure exceeds 182 bar (2639 psi) in the load sensing line, or if there is an overload in the remote circuit. The change in pressure across the combining valve moves the spool to the left, allowing excess oil flow from both pumps in Galleries F and H to be exhausted to return through Gallery G. – Pump pressurized oil – Auxiliary pump oil (if equipped) – Suction oil / return to deposit (1) (2) (3) (4) (5) (6)

Hydraulic systems - Pump control valves

Pump control valve Priority/Regulator valve - Exploded view The priority valve group (PVG), located on top of the hydraulic lift cover contains a set of valves, that establishes pump oil priority, and controls the flow of oil to the lift cylinder, remote valves, and auxiliary equipment.

Flow control valve (FCV) The flow control valve, located in the priority valve group, controls oil flow to the lift control valve, by sensing pressure variations. The flow control valve also diverts surplus oil to the combining valve.

Unload valve (UV) The unload valve, located in the priority valve group, responds to flow control valve movement, and operates in two positions. In the raised position, the valve allows oil to flow to the lift cylinder. In the neutral or lowering position, the valve directs oil to the reservoir (rear axle center casing).

Combining valve (CV) The combining valve regulates the flow of oil to the remote valve circuit, and combines the flow of oil from the main and auxiliary pumps as required. The combining valve performs the following functions: • Directs main hydraulic and optional auxiliary pump oil flow to remote circuits on demand, and returns oil flow to sump when no demand exists. • Directs oil flow to sump if pump output exceeds remote circuit demand. • Protects the remote circuits and auxiliary pump circuit from excessive pressure.

Hydraulic systems - Fixed displacement pump

Any component found unserviceable should necessitate replacing the pump assembly. If an emergency repair is required and worn components are replaced individually, note the following points: â&#x20AC;˘

The installation of new bearings will re-center the gears and prevent the tips of the gear teeth from bottoming, if continuing to use a pump body where the track is out of specifications. Pump inefficiencies will occur.

â&#x20AC;˘

Under working conditions, hydraulic pressure within the pump loads the gears towards the inlet side of the pump body. Continued use of worn bearing and gear journals causes the gears to shift, thus further damaging the gear track in the pump body.

Hydraulic systems - Three-point hitch cylinder

Three-point hitch cylinder - Overview The hydraulic top cover (1) provides a base for mounting the priority valve pack, brackets for the hydraulic lift control lever, draft control lever, and quadrant. In addition, the cover houses the top link sensing and draft control linkage system, hydraulic lift control linkage, lifting cylinder and arms, internal galleries, and covers the rear axle center casing hydraulic reservoir (2). The lift cylinder operates the lift arms to raise, lower and transport an implement. The lift cylinder assembly consists of a control valve, piston, exhaust valve, and a safety valve.

Lift cylinder exhaust valve RCPH10TTS004BAD

The spring-loaded exhaust valve, located in the lift cylinder, restricts the flow of exhaust oil from the lift cylinder, thereby maintaining the rate of drop for controlled lowering.

Lift cylinder safety valve The spring-loaded lift cylinder safety valve, located in the lift cylinder wall, protects the lift cylinder circuit from overloading, such as, when transporting implements over rough ground. The safety valve requires no servicing.

Wash all parts in suitable cleaning solvent and allow the parts to dry.

Check oil passages for obstructions.

Examine valves and bore for wear, burrs or scratches. Remove minor damage to valve with fine emery cloth.

If the control valve bushing requires replacement, remove the bushing using tool FNH02191 or T8510 (1). The control valve bushing is color coded and the original size as fitted by the factory is indicated by a color spot on the cylinder casting adjacent to the control valve bore. Always install a new bushing with the same color code markings. When replacing the bushing, the bushing should be lubricated and drawn through the bore with either FNH02191 or T8510.

Remote control valve - Dynamic description Single remote valve operation – Neutral

• A centering spring holds the control valve spool in neutral, blocking pump supply Gallery B. • The control valve spool also isolates Galleries G and H from pump supply Gallery B, and oil return Galleries E and F. This traps the hydraulic oil in both ends of the lift cylinder. • Galleries C and D connect with the return oil Galleries E and F, allowing pressure in the load sensing lines to return to sump. • The combining valve moves to the left, compressing the spring, and diverts oil flow from the pumps, back to the reservoir through the priority valve pack. – Pump pressurized oil – Trapped oil – Suction oil / return to deposit (1) Flow control restrictor (2) Load check valve (3) Check valve spring (4) Flow control knob (5) Detent regulating valve (6) Detent spool (7) Detent plunger and spring (8) Detent balls (9) Centering spring (10) External cylinder (11) Valve body

Single remote control valve operation – Raising

• With the remote control valve lever in the raise position, the control valve spool moves forward and the springloaded detent balls engage the rear grooves of the detent plunger. • Pump supply Gallery B connects to Galleries G and D while Galleries H and C connect to return through Gallery E. • When initially moving the remote control valve lever, the pressure in Gallery D equalizes with the cylinder pressure, or the hydraulic back-pressure, whichever is greater. • The pressurized oil in Gallery D flows to the shuttle check valve and through an internal drilling to the detent regulating valve, flow control valve spool, and the pilot line (load sensing). • The pilot line (load sensing) pressure from Gallery D acts on the end of the combining valve spool, moving the spool to the right. The return Gallery in the priority valve pack closes and the main hydraulic and auxiliary pump (if equipped) oil pressure flows to the remote valve inlet port. • Pump pressurized oil flows from Gallery A to Gallery B through the flow control valve spool, flow control restrictor, and the load check valve. • The flow control restrictor setting (manually set with the flow control knob) determines the volume of oil entering Gallery B and flowing to Gallery G. • Exhaust oil from the cylinder Gallery H returns to the reservoir through Gallery E. • When the cylinder fully extends, pump supply pressure increases until the detent regulating valve opens. Pump pressurized oil moves the detent spool against the detent spring and releases the clamping effort on the detent balls at the end of the control valve spool. The centering spring now moves the spool back to the neutral position. • With the remote control valve lever in the raise position, the control valve spool moves forward and the springloaded detent balls engage the rear grooves in the detent plunger. – Pump pressurized oil – Suction oil / return to deposit (1) Flow control restrictor (2) Load check valve (3) Check valve spring (4) Flow control knob (5) Detent regulating valve (6) Detent spool (7) Detent plunger and spring (8) Detent balls (9) Centering spring (10) External cylinder (11) Valve body

Single remote valve operation – Lowering with slow flow control setting

• Moving the remote control valve lever to the lowering position forces the control valve spool rearwards, allowing the spring loaded detent balls to engage the front groove on the detent plunger. • Gallery B connects to Galleries H and C, and Gallery G connects to Galleries D and F. This action reverses the connection to-and-from the cylinder. Pressurized oil retracts the remote cylinder in the same manner as described in the raising sequence. • The shuttle check valve enables the pilot line to sense pressure in Gallery C, and directs the flow of oil to operate the detent regulating valve and flow control valve spool. • The flow control restrictor rotates, reducing the slotted area in which oil flows into Gallery B and to the control valve, restricting oil flow to Gallery B. The degree of restriction, causes supply pressure to increase compared to pilot line pressure. • Pressure from the pump supply line, acts on the right hand end of the combining valve, and the spool moves against the spring, diverting surplus oil to sump. – Pump pressurized oil – Reduced oil flow – Suction oil / return to deposit (1) Flow control restrictor (2) Load check valve (3) Check valve spring (4) Flow control knob (5) Detent regulating valve (6) Detent spool (7) Detent plunger and spring (8) Detent balls (9) Centering spring (10) External cylinder (11) Valve body

Hydraulic systems - Remote control valves

Double remote valve operation

• Operation of two or more remote valves simultaneously, is possible irrespective of cylinder load. • When two spools simultaneously operate a light load and heavy load circuit, the oil flowing from the control valve attempts to flow to the light load circuit. The flow control spool maintains the set flow to the light load circuit. • The shuttle ball in the load sense line pushes firmly toward the low pressure circuit, isolating the line from the remote valve operating under the lighter load condition. • Hydraulic oil from pump supply Gallery B flows to the left side of the flow control valve spool through the shuttle check valve. Oil flows through radial holes in the spool at Gallery A to Gallery B. • When pressure differs greatly between two operating remote circuits, an excessive amount of oil flows from the pump supply Gallery B through the flow control valve, via the restrictor, to the remote circuit operating at the lower pressure. This additional flow results in increased pressure generated on the right-hand end of the flow control spool. • The flow control spool moves to the left and compresses the spring, progressively covering the radial holes in the spool. This restricts oil from Gallery A to the load check valve, and eliminates excessive oil flow to the light load circuit, while maintaining supply line pressure from the heavy load circuit. – Pump pressurized oil – Reduced oil flow – Suction oil / return to deposit – Controlled oil flow (1) Flow control restrictor (2) Load check valve (3) Check valve spring (4) Flow control knob (5) Detent regulating valve (6) Detent spool (7) Detent plunger and spring (8) Detent balls (9) Centering spring (10) External cylinder (11) Valve body

Single remote valve operation – Float

• The float position allows operation of single acting cylinders when lowering under light load conditions. • With the remote control lever full forward in the float position, the control valve spool moves rearward past the lowering position to allow engagement of the detent balls with the grooves on the float detent plunger. • The control valve spool requires manual movement to neutral by the operator, as the shuttle check valve generates no pressure to release the detent mechanism. • Galleries E, F, G, and H connect to return, allowing the cylinder to float and assume any position. • Galleries C and D also connect to Galleries E and F, allowing only low back pressure on either side of the shuttle check valve. There is no pressure in the pilot line, and the pump output returns to the reservoir through the combining valve. – Pump pressurized oil – Trapped oil – Suction oil / return to deposit (1) Flow control restrictor (2) Load check valve (3) Check valve spring (4) Flow control knob (5) Detent regulating valve (6) Detent spool (7) Detent plunger and spring (8) Detent balls (9) Centering spring (10) External cylinder (11) Valve body

Hydraulic systems - Remote control valves

Remote control valve - Pressure test WARNING Escaping fluid! Hydraulic fluid or diesel fuel leaking under pressure can penetrate the skin and cause infection or other injury. To prevent personal injury: Relieve all pressure before disconnecting fluid lines or performing work on the hydraulic system. 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

During the pressure test if any hydraulic leaks are noticed repair the leak and repeat the pressure test procedure. Prior operation: Remote control valve - Install (35.204) 1.

Install the inlet hose of a suitable flow meter into the upper port of a remote coupler (1).

Set the corresponding flow control knob (3) to maximum flow.

Install the flow meter return hose into the lower port of the same remote coupler (2) on the tractor.

Fully open the load valve on flow meter.

Ensure all connections are secure. Start tractor and set engine speed to 2100 RPM.

Position the same color remote control lever of the valve in float position, fully forward (1).

Position the remote control lever of the valve tested rearwards, to the extend position (2).

Gradually close the flow meter load valve until a pressure of 137 bar (1987 psi) is obtained. Allow the tractor to run until the hydraulic oil reaches an operating temperature near 75 Â°C (167 Â°F).

Continue to close the flow meter load valve, while observing a steady rise in pressure, until the detent regulating valve opens, at which point the needle on the flow meter gauge fluctuates, and the remote control lever returns to neutral.

10.

The gauge reading immediately preceding needle fluctuation must be within 176 - 182 bar (2552 - 2639 psi) which is the pressure when the detent regulating valve must open.

NOTE: The maximum flow capacity for a remote valve is 13.0 l/min (3.4 US gpm). If the tractor is equipped with an auxiliary engine mounted pump the maximum flow capacity is 15.0 l/min (4.0 US gpm).

Hitches, drawbars, and implement couplings - Rear three-point hitch

Rear three-point hitch - Dynamic description The three-point hitch can operate in either draft control or position control. The control system selected depends on the type of implement in use and the operating conditions. A draft control lever and a position control lever, located on the right-hand side of the operator's seat, provide control of the hydraulic lift system.

Draft control lever The draft control lever (1) operates in a slotted bracket with formed notches to prevent accidental movement of the lever. To move the lever out of the notch, slide the lever to the right to clear the notches and move it to the desired position. A decal adjacent to the draft control lever clearly identifies the draft and position control settings. With the draft control lever in the forward notch (A), the three-point hitch is in the most sensitive setting and variations in soil density cause the hydraulic system to respond to small changes in soil condition. Move the draft control lever progressively rearward to decrease draft control sensitivity. The rearmost notch (B) positions the system in position control. NOTICE: Always set the draft control lever to position control in the rearmost notch when automatic correction of the three-point hitch is not desired, such as when attaching equipment, transporting equipment, or with no equipment attached.

Position control lever The position control lever (2) raises or lowers the threepoint hitch linkage and implement to the required height or working depth. Pushing the position control lever forward lowers the implement. Pulling the position control lever to the rear raises the implement. An adjustable stop (3) provides a means of returning the position control lever to the selected setting during use. To adjust the location of the stop, turn the knob counter-clockwise to loosen it and slide it to the desired position. Tighten the knob. The stop can be bypassed by easing the lever to the right to clear the stop.

Hitches, drawbars, and implement couplings - Rear three-point hitch

Principles of draft control The draft control system manages the working depth of soil engaging implements to maintain an even pull on the tractor, and to reduce wheel slippage. When lowering a soil-engaging implement, e.g. a plow into the ground, the draft forces (A) applied to the implement tend to make the plow pivot at the point where it attaches to the lower links (B). Without the top link, the plow would tip up (C). Due to the top link resistance, the plow stays level in the ground. This creates a compressive force (1) acting on the top link against the tractor. The draft force will vary according to the depth of work and soil type. When draft forces increase beyond selection, the compressive force on the top link (1) pushes the yoke (3) further into the hydraulic lift cover and the three-point hitch raises the implement until the preset draft load is restored. When draft forces decrease below selection, the compressive force on the top link reduces, the yoke moves out from the top cover, and the three-point hitch responds by lowering the implement until the preset draft load is restored.

Hitches, drawbars, and implement couplings - Rear three-point hitch

Top link sensing and three-point linkage Draft forces applied to an implement, transmit mechanically from a rocker (1) and control yoke (2), to the draft control mechanism, via the top link (3) of the three-point linkage. The hydraulic system responds by raising or lowering the implement, to restore and maintain uniform draft loading.

RCPH10TTS069BAD

Draft control â&#x20AC;&#x201C; lowering The draft control lever (11) connects to the control arm (9) by a clevis link. As the control lever moves downward, the arm rises and aligns the control rod and roller assembly (5). The control rod and roller assembly attaches to the far end of the lever arm. The top pivot point of the control link (4) connects to the draft control main spring plunger (1). Downward movement of the lift control lever (10) moves the actuating lever (14) forward. The actuating lever pivots about the control rod connector (8) and allows the control valve spring (7) to move the control valve spool rearward into the lowering position. The lowering action stops, when the implement draft compresses the draft control main spring (2) in a forward direction enough to cause the main spring plunger to move the control link forward. This action causes the control rod to pivot the actuating lever about the top attaching point. The actuating lever overcomes the rearward pressure of the control valve spring and moves the control valve spool forward into the neutral position.

Hitches, drawbars, and implement couplings - Rear three-point hitch

Draft control â&#x20AC;&#x201C; raising An increase in draft to the implement transmits through the yoke (3) to compress the draft control main spring (2), moving the draft control main spring plunger (1) in a forward direction. The control rod and roller assembly (5) connected to the plunger by the control link (4), pivots about the actuating lever (6). The actuating lever overcomes the pressure of the control valve spring (7), and moves the control valve spool forward, into the raise position. As the implement lifts, the draft forces acting on the yoke reduce, and the compression of the draft control main spring eases. The control valve spring moves the control valve spool rearward, back into the neutral position. A further decrease in draft reduces the draft control main spring compression and the pressure on the actuating lever. The control valve spring extends and moves the control valve spool, rearward into the lowering position. As the implement runs deeper, the draft increases and the control valve spool returns to the neutral position.

Draft control â&#x20AC;&#x201C; transport position Pulling the draft control lever (10) to the top of the quadrant selects the transport position. The top of the actuating lever (12) pivots rearwards about the control rod connector, which allows the control valve spring (7) to move the control valve spool forward, into the raise position. To limit the height of the implement, the piston skirt contacts a stop pin attached to the actuating lever, when reaching the full raised position. The control valve spool moves rearward into the neutral position, stopping further movement of the lift piston. The stop pin functions in both draft and position control.

Principles of position control The system of position control enables the working depth or height of an implement, relative to the tractor, to be preset and maintained. During position control, the control rod and roller assembly (5) aligns with the lower end of the control link (4). With the control rod and roller in this position, any variations in draft loading applied to the yoke (3) through the top link and three-point linkage system will not alter the control rod and roller. Consequently, the actuating lever (12) and control valve (7) remain unchanged unless movement of the draft control lever (10) occurs. Moving of the lift control lever (11) pivots the control rod and repositions the control valve spool, to raise and lower the implement as required. As the lift arms move, the position control link (14) rides the position control cam (13), moving the control rod and actuating lever. With the lift arms in the desired position, the actuating lever returns the control valve to neutral, which stops further movement of the lift arms. Therefore, a direct relationship exists between the height of the lift arms and the position of the draft control lever.

Cab climate control - Air conditioning

Air conditioning - Overview The function of the air conditioning system is to create and maintain optimum working conditions inside the cab. The climate inside the cab essentially depends on four factors: • Temperature • Humidity • Speed • Purity of cab air “Ideal” conditions will vary from person to person, and so it is not possible to specify optimum values for the above factors; however, we can specify a range of values within which the majority of people will feel most comfortable. With regards to temperature and humidity, we can define a zone, known as the ‘comfort zone’, within which the temperature and humidity combination corresponds to satisfactory climatic conditions. Figure 1 illustrates that humidity should be within the range of 30 - 70 %. Below 30 % there is excessive dehydration of the mucous tissue of the nose and throat, whereas above 70 % an uncomfortable sense of dampness may be perceived. The temperature may therefore may vary between 18 - 28 °C (64.40 - 82.40 °F). The air flow speed must not be so high as to cause discomfort; speeds of 0.07 - 0.25 m/s (0.23 - 0.82 ft/s) are normally acceptable. With regards to air purity, no precise limits have been defined; however, it is important to remember that the human organism gradually alters the composition of the air in the surrounding environment by breathing, increasing the amount of carbon dioxide and humidity, and decreasing the amount of oxygen, etc. Problems can be eliminated by allowing a small flow of external air to enter the cab. However, as these machines are often used in dusty conditions (dust from the earth, hay, etc.), the installation of dry filters on the external air inlets provides a simple solution. The use of air conditioning in machinery generally serves to neutralize unpleasant climatic conditions inside the cab; the air conditioning system controls the temperature and humidity of the air drawn into and already present in the cab so as to maintain a comfortable climate for the operator. The operating principle of the system is similar to that of a domestic refrigerator: heat is removed from the air by means of a physical process (the evaporation of a liquid) which draws heat from the surrounding environment. The liquid used in this process (refrigerant) is a product with a high refrigeration coefficient, low toxicity and mixes well with lubricating oils. The various components of the system are connected by pipes in which the refrigerant circulates.

Cab climate control - Air conditioning

Air conditioning - Dynamic description The air conditioning system consists of five main components as follows: (see figure 1 for location) • Compressor (1) • Condenser (2) • Filter/drier (3) • Expansion valve (4) • Evaporator (5) To understand the operating cycle of the system, follow the flow of the refrigerant starting from the compressor (1). The compressor draws in vaporized refrigerant at a pressure of 0.5 - 3 bar (7.25 - 43.50 psi) compressing it to a pressure of 16 - 24 bar (232.00 - 348.00 psi) The refrigerant, heated by compression to 60 - 120 °C (140.00 - 248.00 °F), is directed to the condenser coil (2) (still in vapor form) located in front of the engine radiator. The air flow, produced by the electric fan and the forward movement of the machine, cools the refrigerant by means of heat exchange. This action cools the refrigerant to the point of condensation between 40 - 60 °C (104.00 - 140.00 °F) depending on the outside temperature, changing the vapor into liquid. The refrigerant, in liquid state at high pressure, is purified by passing through the filter/dryer (3) from where it flows to the expansion valve (4), which restricts the flow of refrigerant and thus reduces its pressure. As it passes through the expansion valve (4), part of the refrigerant is transformed into vapor and the low temperature mixture of vapor and liquid thus formed enters the evaporator (5). Here the electric fan causes a continuous circulation of the cab air over the fins of the evaporator (5), helping the refrigerant to absorb heat from the air and thus change completely from a liquid to vapor. The evaporation process removes heat from the air passing over the evaporator (5) and thus reduces the temperature inside the cab. The flow of air over the cold surface of the evaporator (5) also condenses some of the moisture in the air and therefore reduces the humidity in the cab. On leaving the evaporator (5) at 0 - 15 °C (32.00 - 59.00 °F) the low pressure mixture is taken in by the compressor (1) to start a new cycle.

Cab climate control - Air conditioning

Air conditioning - Overview Component identification/functionality Compressor • The compressor serves to pressurize the refrigerant and force it through the system. • The compressor is driven by the engine crankshaft via a “V” belt. • The operation of the compressor can be summarized as follows, the valve opening and closing system is automatic, achieved by preloading of the shutter blades. • The rotating parts of the compressor are lubricated by special oil, inserted during assembly, some of which circulates through the system mixed with the refrigerant. Condenser • The condenser is the system component in which the refrigerant vapor condenses to form a liquid. • The condenser works in similar way to the engine cooling radiator, allowing the vapor to give up heat to the external air. • The condenser is comprised of a series of inner tubes through the refrigerant flows and a outer shell consisting of a series of thin aluminium fins which increase the surface area in contact with the cooling air flowing through the condenser. • The condenser is fitted opposite the engine radiator, in the best position for the air flow necessary for heat exchange. Evaporator • The cooling cycle is completed inside the evaporator. • The refrigerant at the expansion valve outlet is a mixture of vapor liquid at low temperature and low pressure. As it passes through the evaporator radiator the refrigerant absorbs heat from the cab air, evaporates, and is then taken in by the compressor as vapor. • The operation of the evaporator is controlled by the expansion valve which regulates the flow of refrigerant to obtain the required degree of air cooling. • The evaporator performs the opposite function to the condenser, but it is constructed in a similar way; the only differences being the overall dimensions and the internal pipe layout. • The evaporator also dehumidifies the air. The air passing over the evaporator contains a certain quantity of moisture, and this must be kept within certain limits for operator comfort. Some of the humidity in the air condenses on the fins of the evaporator. • The centrifugal fan draws the ambient air through the fins of the evaporator (where it is cooled and dehumidified) and into the cab. • The housing around the evaporator is equipped with a condensate trap from which the condensate is carried outside the vehicle through discharge tubes.

Cab climate control - Air conditioning

Filter/drier • The filter/drier, fitted near the compressor and positioned between the condenser and the expansion valve, performs two basic functions: acting as a filter to remove solid and liquid particles from the refrigerant, and as a temporary storage container during variable charge stages. • It is important to eliminate water from the system to prevent corrosion and consequent damage to the components. • The filter therefore contains substances capable of absorbing humidity. Solid particles, such as grit, oxides, metal particles produced by the mechanical wear of the compressor, etc., can also damage the system and so the filter incorporates screens to retain them. Filter/drier components • Pressure port. (1) • Upper screen (2) • Disk (3) • Drying unit (4) • Lower screen (5)

Cab climate control - Air conditioning

Thermostatic expansion valve • This valve serves to reduce the pressure of the liquid refrigerant from the condenser so that the refrigerant entering the evaporator can evaporate and thus take heat from the air which is to be cooled. The expansion valve has two main functions: - metering: the calibrated bore ( (6), 2) inside the valve body creates a difference in the pressure of the refrigerant between the inlet (4) (liquid state) and the outlet (7) (mixed liquid/vapor state); the calibrated bore (6) also serves to atomize the refrigerant to facilitate subsequent evaporation; - modulation: inside the valve body a thermostatic sensor controls the valve aperture so that the right quantity of refrigerant enters the evaporator to ensure complete evaporation. • If the thermostatic sensor ( (2), 2) detects an increase in the temperature of the refrigerant at the evaporator outlet, the flow of refrigerant is increased. • If the temperature in the cab drops or the compressor starts to operate at a higher capacity (due to an increase in engine speed), the flow rate into the evaporator is reduced. • The expansion valve is installed on the evaporator inlet fitting (7), and as the internal refrigerant flow control system is completely automatic, it requires no special maintenance. • To perform functional testing, with the system is fully charged, check that the system operating pressures are those indicated in Air conditioning - General specification (50.200). NOTE: In the event of malfunction, replace the valve. Expansion valve block components/flow description • From the evaporator outlet. (1) • Thermostatic sensor (2) • To compressor suction inlet (3) • From filter/drier (4) • Spring (5) • Calibrated bore and ball (6) • To evaporator inlet. (7)

Adjustable electronic thermostatic switch (Defrost function) • The adjustable electronic thermostat switch safety device fitted with a sensor that, when inserted between the evaporator fins (2), constantly monitors the temperature. • The sensor head contains a gas which is sensitive to evaporator temperature variations, thus varying the volume inside the sensor. • The variation of the volume inside the sensor head (1), acting on a membrane connected to a complex mechanism, opens or closes the electric circuit connected to the compressor electromagnetic clutch. • The opening or closing of the compressor electromagnetic clutch electric circuit causes the compressor to engage or disengage. • The electronic thermostatic switch is adjustable from inside the cab. • The switch acts on a potentiometer designed to allow for variance of temperature. • It is important that the electronic thermostatic switch is always checked and inserted between the evaporator fins, in order that the system can function correctly. NOTE: In the event of malfunction, check the electric circuit of the electronic thermostatic switch and the control installed on the control panel case.

Adjust the level of PAG SP20 oil in the system. When each component was flushed, some PAG SP20 oil was removed from the system. Use the following guidelines when adjusting PAG SP20 oil level: •

If the compressor is to be replaced and the entire system was flushed, the new compressor will contain all the PAG SP20 oil needed and no further adjustment is required.

•

If the compressor is not to be replaced and the entire system was flushed, drain the oil from the compressor to remove any remaining contaminants. Add back to the compressor one container, 250 ml (8.5 US fl oz), of new PAG SP20 oil. (Some oil, about 35 ml (1.2 US fl oz), will remain in the compressor even after it has been drained.)

•

If the entire system was not flushed, drain the oil from the compressor to be installed. Add back new PAG SP20 oil equal to 250 ml (8.5 US fl oz) minus oil amounts still in the components that were not flushed. Use the table below. Component flushed

Flushing Solvent Disposal 8.

Good stewardship of our natural resources is everyoneâ&#x20AC;&#x2122;s business. Flushing solvent is a hazardous material. Never dispose of this solvent by pouring it down the drain or treating it as water soluble waste. Observe all local, state and federal regulations when disposing the solvent.

NOTICE: Never reuse contaminated flushing solvent. Next operation: Air conditioning - Recover (50.200)

If you get refrigerant in your eye, immediately flush your eyes with water for 15 minutes. Seek medical assistance immediately. Failure to comply could result in death or serious injury. W0339A

WARNING Escaping refrigerant may cause frostbite! If you get refrigerant on your skin: -Warm the area with your hand or lukewarm water, 32 - 38 °C (90 - 100 °F). -Cover the area loosely with a bandage to protect the area and the prevent infection. -Seek medical assistance immediately. Failure to comply could result in death or serious injury. W0341A

Air-conditioning refrigerant boils at -12 °C (10 °F)! -NEVER expose any part of the air-conditioning system to a direct flame or excessive heat. -NEVER disconnect or disassemble any part of the air-conditioning system. Discharging refrigerant gas into the atmosphere is illegal in many countries. Failure to comply could result in death or serious injury. W0340A

Prior operation: Air conditioning - Decontaminating - Post flushing procedures (50.200) NOTICE: Some pictures may vary from the model A/C unit you are working on. The procedure is the same. NOTICE: There are no repair procedures for the compressor or compressor clutch. If the clutch or compressor are defective, replace them. NOTICE: Refrigerant contamination has become an issue since the introduction of R134A as a replacement for R-12. Contamination refers to a refrigerant blend and/or mixture of alternative refrigerants and R134A. Typically, R-12 systems which are in need of repair or recharge are suspect to refrigerant contamination due to the number of so called “drop-in” replacements or substitutes for R134A. Systems designed for R134A may be at lower risk for contamination, but precautions should be taken to prevent contamination of service equipment and/or other A/C systems. NOTICE: A refrigerant identifier should be used to determine refrigerant contamination prior to recovery. NEW HOLLAND AGRICULTURE recommends using the refrigerant identifier tool model OEM4450. If a refrigerant contamination level of 2 % or greater is discovered, do not recover the system to a tank with pure R134A refrigerant. Recover only to a tank reserved for contaminated refrigerant. NOTE: Check with your local environmental agency for regulations on the proper disposition of contaminated refrigerant. NOTE: In the United States, EPA regulations require that tanks of contaminated refrigerant be sent to a refrigerant reclaimer for the contents to be purified or destroyed. Call 1-800-296-1996 to locate a reclaimer in your area. Recovered refrigerant passes through an oil separator and a filter-drier before entering the refrigerant tank. The moisture indicator will turn green when dry refrigerant passes over it. 1.

Air-conditioning compressor - Tension adjust Drive belt DANGER Spring under tension! Before trying to remove the tension link nuts, make sure the trip compressor is securely in place. The trip spring must be absolutely fixed into position. Failure to comply will result in death or serious injury. D0055A

Prior operation: Air-conditioning compressor - Install (50.200) The tension and condition of the belt transmitting drive from the engine to the compressor is particularly important with regards to the correct operation of the air conditioning system. The drive belt therefore requires careful attention as follows: 1.

Fit the belt correctly.

Check the tension.

Check the condition of the belt.

Fitting the compressor drive belt •

When first fitted, the belt must not be forced, pulled with a screwdriver, or rolled over the edge of the pulley, as this would stretch the less deformed fabric in the belt thus causing subsequent breakage of the other fabrics.

•

When first fitted, the belt must be installed at a greater tension than normal to compensate for initial stretching during the running-in period. The belt must therefore be checked again after 50 h of operation and adjusted to the normal tension.

•

This check is absolutely essential as if the belt is too taut, in addition to damaging the pulley bearings, it will cause premature fatigue of the reinforcement fabrics and thus early deterioration.

•

If on the contrary the belt is too slack, it will start to slip and overheat, and it will therefore wear out prematurely.

Checking compressor drive belt tension •

Check the tension only when the belt is cool (at a temperature below 40 °C (104 °F).

•

Check the tension by applying a load of 78 98 N (18 - 22 lb) to the center of the belt run indicated in the figure: the belt should deflect approximately 12 - 13 mm (0.5 - 0.5 in) as shown.

83113100

47377790 31/10/2012

50.200 / 49

Cab climate control - Air conditioning

Periodic checking of drive belt When checking the tension, also check the amount of drive belt wear. The main problems are as follows: •

Belt shiny: Smooth sides may slip on pulleys. Corrective action may include adjusting the belt to proper tension or replacement.

•

Belt cracked: May break suddenly due to splits on the inner surface caused by excessive flexure. If cracks are excessive, the belt should be replaced.

•

Worn sides: With the sides worn or the inner surface cracked, the belt can break at any moment. Belt should be replaced.

•

Belt impregnated with grease : The belt will wear more rapidly as the grease will cause softening. This condition will be evidenced by proper belt tension, yet belt extremely hot.

NOTE: If the belt squeaks when running, check the tension and adjust if necessary. If the noise continues, replace the belt. NOTE: If the belt has been stretched and it is not possible to tension it sufficiently, replace it.

Engine starter - Test 1.

Consider the following when testing the starter motor. •

For easier and more rapid diagnosis, and for most conclusive test results, use a battery-starter tester (high rate discharge tester) incorporating a 0 - 20 V voltmeter and a 0 - 1000 A ammeter to diagnose the starting system problems.

•

When using test equipment, follow the manufacturer’s recommended test procedures. If test equipment is not available, complete the following test procedures with a standard 0 - 20 V voltmeter and 0 - 1000 A ammeter to determine the correct operation of the starter without removing it from the engine.

Before testing: •

Check that the battery is fully charged.

•

Check the complete starting system wiring circuit for frayed or broken wires. Also, check for loose terminal connections.

•

Check that the engine is not seized.

Electrical systems - Alternator

Alternator - Static description ISKRA alternators are installed on all models. They incorporate internal cooling fans and integral voltage regulators. The alternator is mounted at the front on the right-hand side of the engine and is driven from a crankshaft pulley via a `poly vee' drive belt.

BSE2983A

Alternator Operation Refer to Wire harnesses - Electrical schematic frame 04 (55.100) for charging circuit schematics. When the key start switch is turned on, a small current flows from the battery through the rotor field wiring. The circuit is made via the charge indicator warning lamp, alternator terminal `D+', the rotor field winding, the alternator regulator, and ground. At this stage, the warning light is illuminated and the rotor partially magnetized. When the engine is started and the partially magnetized rotor revolves within the stator windings, a 3-phase alternating current is generated. A constant portion of the generated current is converted to direct current by the three field diodes incorporated in the rectifier pack. This direct current is fed back to supplement the current flowing through the rotor field winding. This action results in an ever increasing magnetic influence of the rotor along with an associated rapid rise in generated output current and voltage. During the rise in generated output voltage (reflected at the `D+' terminal), the brilliance of the warning lamp is reduced and when the voltage at the `D+' terminal equals that at the battery side of the warning light and the lamp is extinguished. The voltage continues to rise until the predetermined regulated voltage level is reached. In the event of drive belt failure, the voltage will not build up within the alternator and so the charge indicator light will remain on to indicate failure.

Battery - Static description All models use a single “maintenance free" battery with negative ground of six cell construction and is located on the right hand side of the tractor behind the cab steps. NOTE: "Maintenance free" means that under normal charging conditions the battery may lose a small amount of water from the electrolyte. Conditions that may cause water loss include prolonged charging above 14.4 volts where gassing occurs as it approaches full charge. This can be caused by a faulty charging system or boost/recovery charging equipment. The battery has four major functions: • To provide a source of current for starting, lighting and instrumentation. • To help control the voltage in the electrical system. • To furnish current when the electrical demands exceed the alternator output. • To support quiescent loads from radio and micro processor memory. The battery is constructed in such a manner that each cell contains positive and negative plates placed alternatively next to each other. Each positive plate is separated from a negative plate by a non-conducting porous envelope separator. If any of the positive plates should make contact with negative plates within a cell, the cell will short circuit and suffer irreparable damage. All of the positive plates are welded to a bus-bar, forming a positive terminal and all of the negative plates are welded to a similar bus-bar forming a negative terminal. Each positive plate is composed of a lead grid with lead peroxide pasted into the grid openings. The negative plates are composed of a lead grid with spongy lead pasted into the grid openings. The plates are submerged in a liquid electrolyte solution of diluted sulphuric acid.

From inside the cab use a pair of pliers to push the cutting wire (1) through the adhesive (2) between the glass and the frame.

20113042

20113043

Thread the cutting wire (1) into the handle and lock it with the screw (2).

Anchor the pointed end of the tool into the adhesive. Keep the wire close to the glass and pull on the hand grip (2).

Use a tool with suction cups to remove the window and place it on a suitable surface to avoid damaging it.

Completely remove the adhesive from the window surround, taking care not to damage the surrounding area.

Remove the adhesive from the glass using a suitable solvent.

Clean the frame, as described in operation 7.

20113044

20113045

NOTICE: When replacing a broken window, remove the glass fragments still attached to the cab and use a knife blade to cut the adhesive (1), Figure 4, away from the frame. Take care not to damage the frame.

Installation 1.

Make sure that the contact area between the glass and the metal frame in the cab is perfectly clean.

Using a clean tissue, apply the activator (VP 04604 GURIT ESSEX) around the edge of the glass, where contact will be made with the metal frame. Allow to dry.

Shake the bottle of glass primer (Betaprime 5100 GURIT ESSEX) for 60 s. Using the applicator provided (1), apply the primer (2) around the edge of the glass and overtop of the dried activator. Allow to dry thoroughly.

Shake the bottle of metal plate primer (Betaprime 5402 GURIT ESSEX) for 60 s. Use the applicator provided and apply around the metal frame where contact will be made with the glass. Allow to dry thoroughly.

Cut the spout of the adhesive dispenser as shown, to achieve a triangular bead.

Apply a smooth, continuous bead of polyurethane adhesive (Betaseal 1703 GURIT ESSEX) around the edge of the glass over the previously primed area (the cross-section of this bead must be triangular, with a base width of 10 mm (0.39 in) and a height of 10 mm (0.39 in).

20113046

20113047

NOTE: Make sure that the adhesive bead is continuous, i.e., there are no areas where adhesive is missing. Otherwise, water may penetrate. 7.

Insert the window support blocks, if present.

NOTE: Leave the clamps in place for 4 h until the adhesive has completely polymerized. To promote a good bond, do not move the cab or the tractor during this time. 8.

Using a tool with suction cups, position the window in its surround and use suitable clamps to apply a uniform pressure to obtain a 4 mm (0.2 in) thickness of adhesive and ensure perfect adhesion.
