Introduction Foreword This manual is written for an experienced technician. Essential tools required in performing certain service work are identified in this manual and are recommended for use. Live with safety: Read the safety messages in the introduction of this manual and the cautions presented throughout the text of the manual. This is the safety-alert symbol. When you see this symbol on the machine or in this manual, be alert to the potential for personal injury. Technical manuals are divided in two parts: repair and operation and tests. Repair sections tell how to repair the components. Operation and tests sections help you identify the majority of routine failures quickly.

Information is organized in groups for the various components requiring service instruction. At the beginning of each group are summary listings of all applicable essential tools, service equipment and tools, other materials needed to do the job, service parts kits, specifications, wear tolerances, and torque values. Technical Manuals are concise guides for specific machines. They are on-the-job guides containing only the vital information needed for diagnosis, analysis, testing, and repair. Fundamental service information is available from other sources covering basic theory of operation, fundamentals of troubleshooting, general maintenance, and basic type of failures and their causes.

Torque values listed are for general use only, based on the strength of the bolt or screw. DO NOT use these values if a different torque value or tightening procedure is given for a specific application. For plastic insert or crimped steel type lock nuts, for stainless steel fasteners, or for nuts on U-bolts, see the tightening instructions for the specific application. Shear bolts are designed to fail under predetermined loads. Always replace shear bolts with identical grade.

Replace fasteners with the same or higher grade. If higher grade fasteners are used, tighten these to the strength of the original. Make sure fastener threads are clean and that you properly start thread engagement. When possible, lubricate plain or zinc plated fasteners other than lock nuts, wheel bolts or wheel nuts, unless different instructions are given for the specific application.

a

Grade 2 applies for hex cap screws (not hex bolts) up to 6. in (152 mm) long. Grade 1 applies for hex cap screws over 6 in. (152 mm) long, and for all other types of bolts and screws of any length. b

“Lubricated” means coated with a lubricant such as engine oil, fasteners with phosphate and oil coatings, or 7/8 in. and larger fasteners with JDM F13C zinc flake coating. c

“Dry” means plain or zinc plated without any lubrication, or 1/4 to 3/4 in. fasteners with JDM F13B zinc flake coating.

Torque values listed are for general use only, based on the strength of the bolt or screw. DO NOT use these values if a different torque value or tightening procedure is given for a specific application. For stainless steel fasteners or for nuts on U-bolts, see the tightening instructions for the specific application. Tighten plastic insert or crimped steel type lock nuts by turning the nut to the dry torque shown in the chart, unless different instructions are given for the specific application.

Shear bolts are designed to fail under predetermined loads. Always replace shear bolts with identical property class. Replace fasteners with the same or higher property class. If higher property class fasteners are used, tighten these to the strength of the original. Make sure fastener threads are clean and that you properly start thread engagement. When possible, lubricate plain or zinc plated fasteners other than lock nuts, wheel bolts or wheel nuts, unless different instructions are given for the specific application.

If an accident occurs, see a doctor immediately. Any fluid injected into the skin must be surgically removed within a few hours or gangrene may result. Doctors unfamiliar with this type of injury may call the Deere & Company Medical Department in Moline, Illinois, or other knowledgeable medical source.

CAUTION: Escaping fluid under pressure can penetrate the skin causing serious injury. Avoid the hazard by relieving pressure before disconnecting hydraulic or other lines. Tighten all connections before applying pressure. Search for leaks with a piece of cardboard. Protect hands and body from high pressure fluids.

Check Oil Lines And Fittings

Check all oil lines, hoses, and fittings regularly for leaks or damage. Make sure all clamps are in position and tight. Make sure hoses are not twisted or touching moving machine parts. If abrasion or wear occurs, replace immediately. Tubing with dents may cause the oil to overheat. If you find tubing with dents, install new tubing immediately. IMPORTANT: Tighten fittings as specified in torque chart. When you tighten connections, use two wrenches to prevent bending or breaking tubing and fittings.

Fuels and Lubricants 00 0004 1

Diesel Fuel Consult your local fuel distributor for properties of the diesel fuel available in your area. In general, diesel fuels are blended to satisfy the low temperature requirements of the geographical area in which they are marketed. Diesel fuels specified to EN 590 or ASTM D975 are recommended. In all cases, the fuel shall meet the following properties: • Cetane Number 40 minimum. Cetane number greater than 50 is preferred, especially for temperatures below -20°C (-4°F) or elevations above 1500 m (5000 ft). • Cold Filter Plugging Point(CFPP) below the expected low temperature OR Cloud Point at least 5°C (9°F) below the expected low temperature.

• Fuel Lubricity should pass a minimum of 3100 gram load level as measured by the BOCLE scuffing test. • Sulfur content: – Sulfur content should not exceed 0.5% Sulfur content less than 0.05% is preferred. – If diesel fuel with sulfur content greater than 0.5% sulfur content is used, reduce the service interval for engine oil and filter by 50%. – DO NOT use diesel fuel with sulfur content greater than 1.0%. Bio-diesel fuels with properties and meeting DIN 51606 or equivalent specifications may be used. DO NOT mix used engine oil or any other type of lubricant with diesel fuel.

TX,45,JC1132 –19–22MAY96–1/1

Lubricity Of Diesel Fuels Diesel fuel must have adequate lubricity to ensure proper operation and durability of fuel injection system components. Diesel fuels for highway use in the United States and Canada now require sulfur content less than 0.05%. Diesel fuel in the European Union will require sulfur content less than 0.05% by 1 October 1996. Experience shows that some low sulfur diesel fuels may have inadequate lubricity and their use may reduce performance in fuel injection systems due to inadequate lubrication of injection pump components. The lower concentration of aromatic compounds in these fuels also adversely affects injection pump seals and may result in leaks.

engine speed instability, hard starting, low power, and engine smoke. Fuel lubricity should pass a minimum of 3100 gram load level as measured by the BOCLE scuffing test. ASTM D975 and EN 590 specifications do not require fuels to pass a fuel lubricity test. If fuel of low or unknown lubricity is used, add John Deere PREMIUM DIESEL FUEL CONDITIONER (or equivalent) at the specified concentration. John Deere PREMIUM DIESEL FUEL CONDITIONER is available in winter and summer formulas. Consult your John Deere engine distributor or servicing dealer for more information.

Use of low lubricity diesel fuels may also cause accelerated wear, injection nozzle erosion or corrosion,

Low Sulfur Diesel Fuel Conditioner When possible, use existing fuel formulations for engines used off-highway. This fuel will not require any additives to provide good performance and engine reliability. However, many local fuel distributors will not carry both low and regular sulfur diesel fuels. If the local fuel distributor will supply only low sulfur fuel, order and use John Deere PREMIUM DIESEL FUEL CONDITIONER. It provides lubricating properties along with other useful benefits, such as cetane improver, anti-oxidant, fuel stabilizer, corrosion inhibitor and others. John Deere PREMIUM DIESEL FUEL CONDITIONER is specifically for use with low sulfur fuels. Nearly all other diesel fuel conditioners only improve cold weather flow and stabilize long-term fuel storage. They do not contain the lubrication additives needed by rotary fuel injection pumps.

TX,45,DH5857 –19–15AUG97–1/1

Diesel Fuel Storage Proper fuel storage is critically important. Use clean storage and transfer tanks. Periodically drain water and sediment from bottom of tank. Store fuel in a convenient place away from buildings. IMPORTANT: DO NOT store diesel fuel in galvanized containers. Diesel fuel stored in galvanized containers reacts with zinc coating on container to form zinc flakes. If fuel contains water, a zinc gel will also form. The gel and flakes will quickly plug fuel filters, damage injection nozzles and injection pump. DO NOT use brass-coated containers for fuel storage. Brass is an alloy of copper and zinc.

Store diesel fuel in plastic, aluminum, and steel containers specially coated for diesel fuel storage. Avoid storing fuel over long periods of time. If fuel is stored for more than a month prior to use, or there is a slow turnover in fuel tank or supply tank, add a fuel conditioner such as John Deere PREMIUM DIESEL FUEL CONDITIONER or equivalent to stabilize the fuel and prevent water condensation. John Deere PREMIUM DIESEL FUEL CONDITIONER is available in winter and summer formulas. Fuel conditioner also reduces fuel gelling and controls wax separation during cold weather. Consult your John Deere engine distributor or servicing dealer for recommendations and local availability. Always follow manufacturer’s directions on label.

If fuel contains water, a zinc gel will also form. The gel and flakes will quickly plug fuel filters and damage fuel injectors and fuel pumps. DO NOT USE a galvanized container to store diesel fuel.

Store fuel in: • plastic containers. • aluminum containers. • specially coated steel containers made for diesel fuel. DO NOT USE brass-coated containers: brass is an alloy of copper and zinc.

Lubricant Storage Your equipment can operate at top efficiency only when clean lubricants are used.

Make certain that all containers are properly marked to identify their contents.

Use clean containers to handle all lubricants.

Properly dispose of all old containers and any residual lubricant they may contain.

Whenever possible, store lubricants and containers in an area protected from dust, moisture, and other contamination. Store containers on their side to avoid water and dirt accumulation.

DX,LUBST –19–18MAR96–1/1

Alternative and Synthetic Lubricants Conditions in certain geographical areas may require lubricant recommendations different from those printed in this manual.

Synthetic lubricants may be used if they meet the performance requirements as shown in this manual.

Some John Deere brand coolants and lubricants may not be available in your location.

The temperature limits and service intervals shown in this manual apply to both conventional and synthetic oils.

Consult your John Deere dealer to obtain information and recommendations.

Re-refined base stock products may be used if the finished lubricant meets the performance requirements.

DX,ALTER –19–15JUN00–1/1

Mixing of Lubricants In general, avoid mixing different brands or types of oil. Oil manufacturers blend additives in their oils to meet certain specifications and performance requirements.

Consult your John Deere dealer to obtain specific information and recommendations.

Mixing different oils can interfere with the proper functioning of these additives and degrade lubricant performance.

Speed Controls IMPORTANT: The slow idle speed must be adjusted to specification so the injection pump lever only contacts the external slow idle stop (E) and not the internal slow idle stop (G). The internal slow idle stop is adjusted at the factory so it is not contacted when slow idle speed is adjusted to specification. Seals on the injection pump lever shaft may be damaged if internal slow idle stop is used as the stop when injection pump lever is connected to the engine control motor. The engine slow idle speed specification given

is with the engine installed in the machine and the pumps, alternator, and fan installed. 13. Loosen nuts (F) on the external slow idle stop (E). 14.

Never lay a metal object on top of a battery as a short circuit can result. Battery acid is harmful on contact with skin or fabrics. If acid spills, follow these first aid tips:

TS204

CAUTION: An explosive gas is produced while batteries are in use or being charged. Keep flames or sparks away from the battery area. Make sure the batteries are charged in a well ventilated area.

–UN–23AUG88

Handle Batteries Safely

1. Immediately remove any clothing on which acid spills. 2. If acid contacts the skin, rinse the affected area with running water for 10 to 15 minutes. 3. If acid comes into contact with the eyes, flood the eyes with running water for 15 to 30 minutes. See a doctor at once. Never use any medication or eye drops unless prescribed by the doctor. 4. To neutralize acid spilled on the floor, use one of the following mixtures: 0.5 kg (1 lb) of baking soda in 4 L (1 gal) of water, or 0.4 L (1 pt) of household ammonia in 4 L (1 gal) of water. 5. Acid from the batteries can also damage the paint and metal surfaces of the machine. Avoid over filling the battery cells.

Procedure for Testing Batteries Record specific gravity reading for each cell.

1. VISUAL CHECK a. Check for damage such as cracked or broken case and electrolyte leakage.

If high and low readings vary LESS than 0.050 and average specific gravity is between 1.225 and 1.280, battery is fully charged, go to LOAD TEST.

If damage is seen, replace battery. b. Check electrolyte level. (See procedure in this group) If low, add distilled water to specified level and charge battery. c. Check terminals for corrosion. If corroded, clean using a wire brush or battery post cleaner such as JT05838 Battery Post and Clamp Cleaner.

If high and low readings vary LESS than 0.050 and average specific gravity is LESS than 1.225, charge battery and repeat test. If average specific gravity is still LESS than 1.225, replace both batteries. If high and low readings vary MORE than 0.050, charge battery and repeat test. If high and low readings still vary MORE than 0.050, replace both batteries. 3. LOAD TEST Check battery capacity with a load tester such as JT05832 Battery Load Tester. Follow tester manufacturer’s instructions for proper load test procedures.

d. Check posts for looseness. If posts are loose, replace battery.

If one battery fails load test, replace both batteries.

2. HYDROMETER TEST Check specific gravity with a hydrometer or battery tester such as JT05460 Coolant/Battery Tester.

Checking Electrolyte Specific Gravity

–UN–23AUG88

CAUTION: Battery gas can explode. Keep sparks and flames away from batteries. Use a flashlight to check battery electrolyte level.

TS204

Never check battery charge by placing a metal object across the posts. Use a voltmeter or hydrometer. Always remove grounded (-) battery clamp first and replace it last. Sulfuric acid in battery electrolyte is poisonous. It is strong enough to burn skin, eat holes in clothing, and cause blindness if splashed into eyes. Avoid the hazard by: 1. Filling batteries in a well-ventilated area. 2. Wearing eye protection and rubber gloves. 3. Avoiding breathing fumes when electrolyte is added. 4. Avoiding spilling or dripping electrolyte. 5. Use proper jump start procedure. If you spill acid on yourself:

–UN–23AUG88

1. Flush your skin with water. 2. Apply baking soda or lime to help neutralize the acid. 3. Flush your eyes with water for 15—30 minutes. Get medical attention immediately.

TS203

If acid is swallowed: 1. Do not induce vomiting. 2. Drink large amounts of water or milk, but do not exceed 1.9 L (2 quarts). 3. Get medical attention immediately.

–UN–10NOV88

Check the specific gravity of electrolyte in each battery cell using a battery and coolant tester such as JT05460 Coolant and Battery Tester.

Adding 12-Volt Accessories

Converter capacity requirements depend on the load of the accessories installed. Follow electronic dealer and manufacturer’s recommendations to determine the capacity of the converter required and its installation requirements.

T6520AJ1

When possible, use 24-volt accessories. If 12-volt accessories are added, use a 24-volt-to-12-volt converter. Converters are available from your John Deere dealer (see the Industrial Equipment Attachment Guide) or electronic retail stores. This converter may be wired into the ACC terminal of the ignition switch (see drawing).

–UN–18OCT88

IMPORTANT: This machine has a 24-volt electrical system. Installing 12-volt accessories without addition of 24-volt-to-12-volt converter may cause battery failure. See your John Deere dealer.

A—Battery B—24 Volts C—Ignition Switch D—ACC Terminal E—Converter F—12 Volts G—In-Line Fuse H—12-Volt Accessory

DO NOT connect an accessory to one battery. Connecting a 12-volt accessory to one battery will cause one battery to overcharge, and the other battery to undercharge, causing battery failure.

Welding Repair of Major Structure CAUTION: Avoid potentially toxic fumes and dust. Hazardous fumes can be generated when paint is heated by welding, soldering, or using a torch. Do all work outside or in a well ventilated area. Dispose of paint and solvent properly. If you sand or grind paint, avoid breathing the dust. Wear an approved respirator. If you use solvent or paint stripper, remove stripper with soap and water before welding. Remove solvent or paint stripper containers and other flammable material from area. Allow fumes to disperse at least 15 minutes before welding or heating. 1. Remove paint before welding or heating. IMPORTANT: Disconnect battery ground strap or turn battery disconnect switch to “OFF”. Also disconnect the wiring harness connectors to the engine and pump controller. Have only a qualified welder do this job. Connect welder ground clamp close to each weld area so electrical current does not pass through any bearings. Remove or protect all parts that can be damaged by heat or weld splatter. 2. Use one of the following weld processes:

• AWS-ER-70S-3 wire electrode with gas metal arc welding (GMAW) process. • AWS-E70T-1 or E71T-1 wire electrode with flux core arc welding (FCAW) process. Specification Weld Metal—Tensile Strength ....................... 482.6 mPa (70,000 psi) Yield Strength ................................................ 413.7 mPa (60,000 psi) Elongation ..................................................................................... 22%

IMPORTANT: Area to be repaired must be preheated to allow better weld penetration. 3. To repair weld metal failure, remove failed weld metal using arc or grinding equipment. Thoroughly clean area to be welded. Preheat structural assemblies to a minimum of 38°C (100°F). Preheat ground engaging tools (cutting edges, skid shoes, and teeth shanks) to 177°C (350°F). To repair base metal failure remove enough material to allow weld to penetrate to the bottom of crack. Preheat structural assemblies to a minimum of 38°C (100°F). Preheat ground engaging tools (cutting edges, skid shoes, and teeth shanks) to 177°C (350°F). Specification Structural Assembly—Preheat Temperature ................................................................... 38°C (100°F) Ground Engaging Tool— Preheat Temperature.................................................... 177°C (350°F)

Heating and Air Conditioning

Proper R134a Refrigerant Handling The U.S. Environmental Protection Agency prohibits discharge of any refrigerant into the atmosphere, and requires that refrigerant be recovered using the approved recovery equipment. IMPORTANT: To meet government standards relating to the use of refrigerants, R134a is used in the air conditioning system. Because it does not contain chlorine, R134a is not detrimental to the ozone in the atmosphere. However, it is illegal to discharge any refrigerant into the atmosphere.

It must be recovered using the appropriate recovery stations. IMPORTANT: Use correct refrigerant recovery, recycling and charging stations. DO NOT mix refrigerants, hoses, fittings, components or refrigerant oils. Recovery, recycling and charging stations for R12 and R134a refrigerants MUST NOT be interchanged. Systems containing R12 refrigerant use a different oil than systems using R134a. Certain seals are not compatible with both types of refrigerants.

TX,18,UU3709 –19–23JUN97–1/1

R134a Refrigerant Cautions CAUTION: DO NOT allow liquid refrigerant to contact eyes or skin. Liquid refrigerant will freeze eyes or skin on contact. Wear goggles, gloves and protective clothing. If liquid refrigerant contacts eyes or skin, DO NOT rub the area. Splash large amounts of COOL water on affected area. Go to a physician or hospital immediately for treatment. DO NOT allow refrigerant to contact open flames or very hot surfaces such as electric welding arc, electric heating element and lighted smoking materials. DO NOT heat refrigerant over 52°C (125°F) in a closed container. Heated refrigerant will develop high pressure which can burst the container.

Keep refrigerant containers away from heat sources. Store refrigerant in a cool place. DO NOT handle damp refrigerant container with your bare hands. Skin may freeze to container. Wear gloves. If skin freezes to container, pour COOL water over container to free the skin. Go to a physician or hospital immediately for treatment. (R12 ONLY) Refrigerant exposed to high temperature forms phosgene gas. Inhaling toxic phosgene gas may result in serious illness or death. Phosgene gas has an odor like new mown hay or green corn. If you inhale phosgene gas, go to a physician or hospital immediately for treatment.

R134a Compressor Oil Charge Check Remove compressor if R134a leakage was detected and repaired. See Remove and Install Compressor in Repair Manual.

3. Flush the complete system with TY16134 air conditioning flushing solvent.

Drain oil from the compressor and record the amount. See Compressor Oil Removal procedure in this group.

4. If the compressor is serviceable, pour flushing solvent in the manifold ports and internally wash out the old oil.

NOTE: Drain oil and save if this is a new compressor.

5. Install a new receiver-dryer.

If the oil drained from a compressor removed from operation is very black or the amount of oil is less than 6 mL (0.2 fl oz.), perform the following:

6. Install required amount of TY22025 refrigerant oil in the compressor. (See R134a Component Oil Charge in this group.)

1. Remove and discard the receiver-dryer.

7. Connect all components, evacuate and charge the system.

2. Remove, clean, but do not disassemble the expansion valve.

R134a Component Oil Charge CAUTION: All new compressors are charged with a mixture of nitrogen, R134a refrigerant and TY22025 (R134a) refrigerant oil. Wear safety goggles and discharge the compressor slowly to avoid possible injury. Compressors can be divided into three categories when determining the correct oil charge for the system. • New compressor from parts depot. • Used compressor removed from operation. • Compressor internally washed with flushing solvent. Determining the amount of system oil charge prior to installation of compressor on a machine. 1. When the complete system, lines, and components were flushed add the correct amount of oil as described. • New compressor from parts depot contains the amount of new oil of 230 ± 20 mL (7.7 ± 0.7 fl oz.). System requires an additional amount of new oil of 100 mL (3.4 fl oz.) of new oil. • Used compressor removed from operation, oil drained, and flushed requires 330 ± 20 mL (11.1 ± 0.7 fl oz.) of new oil.

• Used compressor removed from operation and oil drained. (See Compressor Oil Removal procedure in this group.) Add 45 mL (1.5 fl oz.) of new oil. • Used compressor removed from operation, oil drained, and flushed add 60 mL (2.0 fl oz.) of new oil. NOTE: Components listed below which have been removed, drained, or flushed, require the removal of the compressor to determine the correct oil charge. Use the following chart as a guide for adding oil to components: Evaporator

130 mL (4.4 fl oz)

Condenser

65 mL (2.2 fl oz)

Receiver-Dryer

30 mL (1.0 fl oz)

Hoses

60 mL (2.0 fl oz)

NOTE: Hoses = 3 mL per 30 cm (0.1 fl oz. per ft). Approximate total length equals 600 cm (20 ft). If any section of hose is removed and flushed or replaced, measure the length of hose and use the formula to determine the correct amount of oil to be added.

2. When the complete system was not flushed add the correct amount of oil for the compressor plus amount of oil for each component that was serviced. • New compressor from parts depot, drain and return 45 mL (1.5 fl oz.) of oil to the compressor. (See Compressor Oil Removal procedure in this group.)

CAUTION: DO NOT leave the system or R134a compressor oil containers open. This oil easily absorbs moisture. DO NOT spill R134a compressor oil on acrylic or ABS plastic. This oil will deteriorate these materials rapidly. Identify R134a oil containers and measures to eliminate accidental mixing of different oils.

IMPORTANT: Good welds are important. Have only a qualified welder do the welding. Before welding, clean all dirt and paint from weld area. Connect the welder ground clamp as close to each weld area as possible so electrical current does not pass through any bearings or bushings. 4. Before welding shank, remove tooth tip so rubber pin lock is not damaged by heat.

5. Install shank into corner so it is tight against bevel edge and side of bucket. Install center shanks so they are tight against bevel edge and spaced equally across width of bucket. 6. Tack weld at top rear center to hold it in position. Use E7018 electrodes for welding or Lincoln Electric Co. gasless flux core process electrode type NS3M. 3/32 or 1/8 in. rod may be used.

Before welding on the machine, the battery ground cable and wiring harness connectors to the engine and pump controller must be disconnected to protect the machine’s electrical system. 1. Disconnect battery ground strap and wiring harness connectors to engine and pump controller. (See Welding on Machine in this group.) 2. Perform welding in an environment with a minimum ambient temperature of 10°C (50°F). 3. Clean all joints to be welded of all foreign matter such as dirt, rust, mill scale, oil, etc. with grinders and/or solvents. 4. Use dry AWS-E7018 low hydrogen electrodes or either of the following equivalent low hydrogen wire feed electrodes: gas metal arc welding (CO2 or argon CO2) AWS-E70S6 or flux cored arc welding AWS-E70T1.

33 3302 7

TEMPERATURE MUST BE THROUGHOUT THE ENTIRE THICKNESS OF THE PARTS JOINED AND AT LEAST 51 mm (2 in.) BACK FROM THE JOINT. Maintain preheat throughout the entire welding operation. Tempilstiks should be used if possible. 6. Tack weld preheated plates starting at center of bucket and working towards the outside ends. 7. Final weld preheated plates starting at the center of front edge of bucket backing plate and working towards the outside ends. Repeat this operation at back edge of plates. Tack welds may be incorporated into the final weld, providing they have been made with electrodes that meet the requirements of the final welds and no cracking has occurred in the weld metal. Tack welds not meeting these requirements must be completely removed by grinding or air arc gouging just prior to making the final weld in that area. 8. Do not remove bucket from welding environment until weld metal temperature has dropped to the ambient temperature. Do not force cooling rate of weld metal.

5. Preheat parts to be welded (both tack and final welds) to minimum of 204°C (400°F). PREHEAT

Lower Boom with Engine Stopped

–UN–08DEC08

When an engine stops during operation, the boom cannot be lowered using the pilot controller because there is no pilot pressure oil to move the boom valve spool.

X9811

CAUTION: To avoid injury from escaping fluid under pressure, never loosen boom manual lower needle valve more than 4 turns from closed position, as valve may come out of housing. Tighten valve and nut before applying pressure. Prevent possible injury from unexpected machine movement. Clear all persons from the area around machine before lowering boom with engine stopped. 1. Remove the control valve access cover. 2. Loosen nut (C).

–UN–01APR98

3. Check that area around machine is clear of all persons before lowering boom.

T114374

Slowly, loosen boom manual lower needle valve (B) 1/2—1 turn. The boom will start to lower. Turn needle valve out more to increase boom lowering speed or in to decrease lowering speed. Remember, no more than 4 turns from the closed position. 4. After bucket is on the ground, first tighten needle valve (B) then nut (C).

Hydraulic Oil Cleanup Procedure Using Portable Filter Caddy 1. Install new return filter elements.

5. Start engine and run at fast idle.

NOTE: For a failure that creates a lot of debris, remove access cover from hydraulic oil tank. Drain the tank. Connect filter caddy suction line to drain port. Add a minimum of 19 L (5 gal) of oil to the tank. Operate filter caddy and wash out the tank.

IMPORTANT: For the most effective results, cleaning procedure must start with the smallest capacity circuit then proceed to the next larger capacity circuit.

IMPORTANT: The minimum ID for a connector is 1/2 in. to prevent cavitation of filter caddy pump. 2. Put filter caddy suction and discharge wands into the tank filler hole so ends are as far apart as possible to obtain a thorough cleaning of oil. 3. Start filter caddy. Check to be sure oil is flowing through filters. Operate filter caddy until all oil in tank has been circulated through filter a minimum of four times. Hydraulic Oil Cleanup Procedure—Specification Hydraulic Oil Tank Filtering— Capacity ................................................... 159 L (42 gal) approximate Time ............................................................... 14 minutes approximate

6. Starting with smallest capacity circuit, operate each function through a complete cycle. Repeat procedure until total system capacity has circulated through filter caddy seven times. Each function must go through a minimum of three complete cycles for a thorough cleaning of oil. Hydraulic Oil Cleanup Procedure—Specification Hydraulic System Filtering— Capacity ................................................... 322 L (85 gal) approximate Time ............................................................... 51 minutes approximate

NOTE: Filtering time for complete hydraulic system is 0.158 minute x number of liters (0.6 minute x number of gallons). Filtering time for machines with auxiliary hydraulic functions must be increased because system capacity is larger. 7. Stop engine. Remove filter caddy.

NOTE: Filtering time for hydraulic oil tank is 0.089 minute x number of liters (0.33 minutes x number of gallons). 4. Leave filter caddy operating for next step.

8. Install new return filter elements. 9. Check oil level in tank and add oil if necessary. (See Hydraulic Oil in Group 0004.)

12. Check cap seal. Seal must fit tight against O-ring and not turn. If seal can be turned, it has been stretched too much and can be damaged during assembly into cylinder barrel. 13. For a cap seal that has been stretched too much, shrink it to its original size using a ring compressor or a plastic tie band and hose clamp. When using a ring compressor, put a piece of shim stock between cap seal and compressor at joint so it does not damage seal.

When using a plastic tie band and hose clamp, grind a taper on one end of tie band. Install tie band with taper against cap seal. Before tightening the hose clamp, check to be sure tie band is under hose clamp all around piston.
