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.

DO NOT use these values if a different torque value or tightening procedure is given for a specific application. Torque values listed are for general use only. Check tightness of fasteners periodically.
Make sure fastener threads are clean and that you properly start thread engagement. This will prevent them from failing when tightening.
Shear bolts are designed to fail under predetermined loads. Always replace shear bolts with identical property class.
Tighten plastic insert or crimped steel-type lock nuts to approximately 50 percent of the dry torque shown in the chart, applied to the nut, not to the bolt head. Tighten toothed or serrated-type lock nuts to the full torque value.
Fasteners should be replaced with the same or higher property class. If higher property class fasteners are used, these should only be tightened to the strength of the original.

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
X9811
00 0003 6
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. 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.
Fuel lubricity should pass a minimum of 3100 gram load level as measured by the BOCLE scuffing test.
In general, diesel fuels are blended to satisfy the low temperature requirements of the geographical area in which they are marketed.
Sulfur content:
Diesel fuels specified to EN 590 or ASTM D975 are recommended. In all cases, the fuel shall meet the following properties: Cetane number of 40 minimum. Cetane number greater than 50 is preferred, especially for temperatures below -20°C (-4°F) or elevations above 1500 m (5,000 ft).
• 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 may be used ONLY if the fuel properties meet DIN 51606 or equivalent specification. DO NOT mix used engine oil or any other type of lubricant with diesel fuel.
Cold Filter Plugging Point (CFPP) below the expected low temperature OR Cloud Point at least 5°C (9°F) below the expected low temperature.
TX,45,JC1132 –19–22MAY96–1/1
Lubricity of Diesel Fuel 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 require sulfur content less than 0.05%. Diesel fuel in the European Union requires sulfur content less than 0.05%.
Use of low lubricity diesel fuels may also cause accelerated wear, injection nozzle erosion or corrosion, 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.
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.
If fuel of low or unknown lubricity is used, add John Deere PREMIUM DIESEL FUEL CONDITIONER (or equivalent) at the specified concentration.

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,JC2126 –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.

The following oil is also recommended:
The following oil is preferred:
Other oils may be used if they meet API Service Classification CG-4.
• John Deere TORQ-GARD SUPREME
• John Deere PLUS-50
Multi-viscosity diesel engine oils are preferred. If John Deere PLUS-50 engine oil and a John Deere oil filter are used, the service interval for oil and filter changes may be extended by 50 hours.
If diesel fuel with sulfur content greater than 0.5% is used, reduce the service interval by 50%.

Cold Weather Starting Aids NOTE: All machines are shipped from the factory with a 50-50 mixture for protection to -34°C (-30°F). Adjust mixture accordingly to provide freeze protection for your machine. • Fill radiator to the bottom of the radiator fill neck. • Fill the recovery tank to the FULL mark. Deaeration The cooling system requires several warm-up and cool down cycles to deaerate. It will NOT deaerate during normal operation. Only during warm-up and cool down cycles will the system deaerate. • Start engine. Run engine until coolant reaches a warm temperature. • Stop engine. Allow coolant to cool. • Check coolant level at recovery tank. • Repeat Steps 1—3 until recovery tank coolant level is repeatedly at the same level (stabilized).
NOTE: The level of the coolant in the cooling system MUST BE repeatedly checked after all drain and refill procedures to insure that all air is out of the system which allows the coolant level to stabilize. Check coolant level only when the engine is cold.

Hydraulic System IMPORTANT: When a machine is started for the first time after cylinder rebuild or oil is drained from cylinder, the Loader Start-Up Procedure must be performed to prevent oil from “dieseling” inside the cylinder. 9. Perform Loader Start-Up Procedure (Steering Cylinder). (See procedure in this group.)
TX,0960,RB89 –19–29MAR99–3/3
Loader Start-Up Procedure (Steering Cylinder) IMPORTANT: System pressure must be reduced when performing this procedure. Adjust the LS valve to decrease system pressure. Turning the LS valve counterclockwise decreases system pressure. 1. Remove loader frame access cover. 2. Loosen lock nut on LS valve. Turn LS valve counterclockwise 2.5 complete turns. This will decrease system pressure to approximately 8274— 8963 kPa (82.74—89.63 bar) (1200—1300 psi). IMPORTANT: Perform procedure with engine at low idle (no acceleration.) 3. Slowly articulate the loader 3/4 turn to the right and then 3/4 turn to the left. Do not make contact at loader frame stops. 4. Repeat previous step four times.
09 0960 11
5. Articulate the loader fully to the right and then fully to the left. Repeat four times. 6. Reset system pressure by turning LS valve clockwise 2.5 turns. Check pressures. See Group 9025-25. 7. Install loader frame access cover.

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: 1. Flush your skin with water. 2. Apply baking soda or lime to help neutralize the acid. 3. Flush your eyes with water for 10—15 minutes. Get medical attention immediately. If acid is swallowed: 1. Drink large amounts of water or milk. 2. Then drink milk of magnesia, beaten eggs, or vegetable oil. 3. Get medical attention immediately. IMPORTANT: Electrolyte can damage paint and metal surfaces of your machine. Do not overfill the battery cells. If electrolyte spills on the floor, use one of the following mixtures to neutralize the acid: 0.5 kg (1 lb) baking soda in 4 L (1 gal) water, or 0.47 L (1 pt) household ammonia in 4 L (1 gal) water.

Procedure for Testing Batteries IMPORTANT: If either battery is damaged or won’t hold a charge, both batteries must be replaced. Visual Check 1. Check for damage such as cracked or broken case and electrolyte leakage. If damage is seen, replace battery.
2. Record specific gravity reading for each cell. 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 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.
2. Check electrolyte level. (See procedure in this group) If low, add distilled water to specified level and charge battery.
Load Test 3. Check terminals for corrosion. If corroded, clean using a wire brush or battery post cleaner such as JT05838 Battery Post/Clamp Cleaner.
1. Check battery capacity with a load tester such as JT05832 Battery Load Tester. Follow tester manufacturer’s instructions for proper load test procedures. 2. If one battery fails load test, replace BOTH batteries.
4. Check posts for looseness. If posts are loose in one battery, replace BOTH batteries. Hydrometer Test 1. Check specific gravity with a hydrometer or battery tester such as JT05460 Coolant/Battery Tester.

Amp Crimper Tool for Transmission Controller Unit Connector—Contact Support Adjustment NOTE: The contact support is preset prior to shipment, but minor adjustment may be necessary. 1. Make a sample crimp and determine if the contact is straight, bending upward, or bending downward. 2. If adjustment is required, loosen the screw that holds the contact support onto the locator assembly.
NOTE: The ratchet has detents that create audible clicks as the tool handles are closed. 3. Place a contact with wire into the proper nest and close the tool handles until the ratchet reaches the sixth click, or until the contact support touches the contact. 4. Slightly loosen the nut that holds the locator assembly onto the tool frame. 5. Move the contact support as required to eliminate the bending of the contact. 6. Tighten the nut and close the handles until the ratchet releases. 7. Remove and inspect the contact. 8. Make another sample crimp. If the contact is straight, tighten the contact support screw. If the contact is still being bent during crimping, repeat the adjustment procedure.

2. Hold the tool so that the back (wire side) is facing you. Squeeze tool handles together and allow them to open fully. 3. Holding the contact by the mating end, insert the contact—insulation barrel first—through the front of the tool and into the appropriate crimp section. IMPORTANT: Make sure that both sides of the insulation barrel are started evenly into the crimping section. Do NOT attempt to crimp an improperly positioned contact. 4. Position the contact so that the mating end of the contact is on the locator side of the tool, so that the open “U” of the wire and insulation barrels face the
top of the tool. Place the contact up into the nest so that the movable locator drops into the slot in the contact. Butt the front end of the wire barrel against the movable locator. 5. Hold the contact in position and squeeze the tool handles together until ratchet engages sufficiently to hold the contact in position. Do NOT deform insulation barrel or wise barrel. 6. Insert stripped wire into contact insulation and wire barrels until it is butted against the wire stop. 7. Hold the wire in place: squeeze tool handles together until ratchet releases. Allow tool handles to open and remove crimped contact.

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.
TS220
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. Remove paint before welding. IMPORTANT: Disconnect battery ground strap or turn battery disconnect switch to OFF (if applicable). Disconnect both negative and positive battery cables and microprocessor unit (if applicable). 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. Use one of the following weld processes: • AWS-E-7018 covered electrode with shielded metal arc welding (SMAW) process. • AWS-ER-70S-3f wire electrode with gas metal arc welding (GMAW) process. • AWS-E70T-1 or E71T-1 wire electrode with flux core arc welding (FCAW) process.

Remove and Install Windowpanes The adhesive used to hold the windowpanes in place is a urethane adhesive that is used on most automobile windshields. Urethane adhesive manufactured by Loctite Corporation or equivalent is recommended. DO NOT use any other type of adhesive. It is also recommended that an auto glass dealer install the windowpanes.
18 1810 2
IMPORTANT: Windowpanes must have an ultra-violet barrier around the edge of the glass since ultra-violet rays will deteriorate the adhesive. Windowpanes ordered through John Deere Parts have the ultra-violet barrier. If the windowpane is purchased through a glass dealer, the dealer must put an ultra-violet barrier on the glass. DO NOT apply paint to the border of the glass. If an auto glass dealer is not installing the windowpanes, use the following procedure: 1. Purchase urethane adhesive from your local auto glass dealer. 2. If window frame is removable, remove frame from cab.
3. Scrape broken glass off existing adhesive. DO NOT remove adhesive from window frame or cab. IMPORTANT: Adhesive will not stick to bare metal. 4. If existing adhesive is removed from frame and paint is scraped off window frame, paint window frame. Paint must be fully cured before installing windowpane. 5. Trim existing adhesive so it has a smooth surface. 6. Follow the manufacturer’s instructions for using the adhesive. 7. Apply a 6 mm (1/4 in.) bead of adhesive on top of the existing adhesive. 8. Put a new windowpane into position. Use hand pressure to force windowpane down around the edges until even with metal frame. 9. If windowpane is installed directly on cab, use duct tape to hold it in place while adhesive cures. 10. Allow adhesive to cure for 24 hours before operating machine.

Heating and Air Conditioning
Refrigerant Theory of Operation The compressor (G) draws low pressure gas (H) from the evaporator (I) and compresses it into high pressure gas (F). This causes the temperature of the refrigerant to rise higher than that of the outside air. High pressure gas leaves the compressor and is sensed by the high pressure switch (K). The switch monitors refrigerant pressure. If the pressure becomes too high, the switch will open and stop the compressor, interrupting the cycle. As the high pressure gas flows through the condenser (E), heat is removed and transferred to the outside air being drawn through the condenser core by the condenser fan (D). Cooling the refrigerant causes it to condense and it leaves the condenser as a high pressure liquid (C). The high pressure liquid flows into the receiver-dryer (B) where moisture and contaminants (acid, solids, etc.) are removed. The receiver-dryer also acts as a reservoir for refrigerant. The refrigerant flows from the receiver-dryer to the expansion valve (J) and is sensed by the low pressure switch (A). The switch monitors refrigerant pressure. If the pressure becomes too low from refrigerant loss, the switch will open and stop the compressor, interrupting the cycle. The actual cooling and drying of cab air takes place at the evaporator. Flow of the high pressure liquid refrigerant is controlled by the expansion valve. The expansion valve causes the temperature and pressure of the refrigerant to drop, where it becomes a low pressure liquid (L). The expansion valve is a
diaphragm-type valve that uses a variable orifice to control the flow of high pressure liquid refrigerant into the evaporator to maintain a constant pressure and temperature. (See Expansion Valve Operation in this group for additional information on theory of operation.) The blower motor (N) pulls a mixture of warm cab and outside air through the evaporator where it is cooled by the refrigerant. The heat absorbed by the evaporator causes the refrigerant to vaporize into a low pressure gas. A freeze control switch (M) senses temperature of the evaporator coil through a refrigerant filled capillary tube. The switch closes when the evaporator is above the switch setting and opens when the evaporator is cooled to the switch setting. The switch has a low temperature setting that prevents the evaporator from becoming cold enough to freeze moisture that condenses on the coil. Cab temperature is controlled by reheating the conditioned air by passing it through the heater coil. The heater coil temperature is controlled by regulating the amount of water flow through the heater coil with the water valve. The moisture, from the warm air, is condensed as it contacts the cool evaporator coil during the cooling process and is drained away through drain tubes connected to the drain pan under the evaporator. With the cab air cooled and dehumidified, the refrigerant cycle is complete.

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.
18 1830 12
• New compressor from parts depot • Used compressor removed from operation • Compressor internally washed with flushing solvent Use the following procedure to determine 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 ± .7 fl oz). System requires an additional amount of new oil of 135 mL (4.58 fl oz) of new oil. • Used compressor removed from operation, oil drained, and flushed requires 365 mL (12.35 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
158 mL (5.4 fl oz)
Condenser
70 mL (2.4 fl oz)
Receiver-Dryer
37 mL (1.25 fl oz)
Hoses
73 mL (2.5 fl oz)
NOTE: Hoses = 3 mL per 30 cm (0.1 fl oz per ft). Approximate total length equals 727 cm (24 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 the 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.

Leak Testing 1. Inspect all lines, fittings and components for oily or dusty spots. When refrigerant leaks from the system, a small amount of oil is carried out with it.
3. If a leak detector is used, move the leak detector probe under the hoses and around the connections at a rate of 25 mm (1 in.) per second.
2. A soap and water solution can be sprayed on the components in the system to form bubbles at the source of the leak.
4. Some Freon manufacturers add dye to Freon to aid in leak detection.

Refrigerant Hoses and Tubing Inspection IMPORTANT: Hose used for air conditioning systems contains special barriers in its walls to prevent migration of refrigerant gas. DO NOT use hydraulic hoses as replacement hoses in the air conditioning system. Use ONLY certified hose meeting SAE J51b requirements. When a component is disconnected from the system, special care should be given to inspecting hoses and tubing for moisture, grease, dirt, rust, or other foreign
material. If such contamination is present in hoses, tubing, or fittings and cannot be removed by cleaning, then replace parts. Fittings that have grease or dirt on them should be wiped clean with a cloth dampened with alcohol. Chlorinated solvents (such as trichloroethylene) are contaminants, and must not be used for cleaning. To assist in making leak-proof joints in R134a systems, use a small amount of clean polyakyleneglycol (PAG) refrigerant oil on all hoses and tube connections. Dip O-rings in PAG oil before assembly.

Air Conditioner System Cleaning Procedures Flushing: Flushing the system or component is a cleaning process using a liquid solvent to remove oil and debris. Purging is always necessary after flushing to remove solvent from the system or component.
Purging: Purging the system or a component is a cleaning process using a gas to force liquid from the system. Purging alone will not remove refrigerant oil from the system.
Following is a list of situations that require a flushing procedure be done:
Following is a list of situations that require a purging procedure be done:
• The compressor has an internal failure. • No oil remains in used compressor. • Oil drained from compressor appears or smells overheated. • System was contaminated with a mixture of refrigerant oils. • System was left open to the atmosphere long enough for dirt, moisture, or debris to enter the tubing or components. • System has an internal blockage.
• After flushing system with solvent, to prevent oil dilution • System was contaminated with nitrogen or two refrigerants. • System was left open to the atmosphere and flushing could not be performed. • Installation of new lines, condenser, or evaporator was required.
The following solvent is recommended for flushing air conditioner systems. Use only solvents with an equivalent MSDS.
18 1830 19
Evacuating: Evacuating the system is a process to remove air and moisture from the system, creating a vacuum.

Purge Air Conditioner System IMPORTANT: Air compressors used for purging systems require a water separator. Purging without a separator adds moisture, creating hydrofluoric acid when combined with refrigerant oil. Acid is corrosive to metal tubing. 1. Connect dry nitrogen hose to gauge manifold center hose. 18 1830 20
2. Connect gauge manifold suction hose to compressor suction port, and open valves. 3. Connect gauge manifold discharge hose to compressor discharge post, and open valve. Disconnect discharge hose from gauge manifold to allow purging nitrogen to atmosphere. 4. Open nitrogen tank valve and adjust regulator to 275 kPa (40 psi) (2.75 bar). Purge system for two minutes. Disconnect nitrogen supply. 5. Evacuate system. (See procedure in this group.)

Flush Air Conditioner System Add flushing solvent to system with JT02075 Flusher and JT02098 Fitting Kit.
NOTE: Flushing can be performed on vehicle.
IMPORTANT: DO NOT attempt to flush through compressor or receiver-dryer. Flushing through expansion valve is acceptable if refrigerant oil has normal odor and appearance.
1. Recover refrigerant. (See procedure in this group.) 6. To Flush/Purge Condenser: 2. Remove compressor and measure oil drained from both manifold ports.
Connect flusher outlet hose to inlet end of compressor discharge line using JT02102 Adapter.
3. Clean compressor as follows: a. Pour 240 mL (8 fl oz) of flushing solvent into suction port and 120 mL (4 fl oz) into discharge port. Plug both ports in compressor manifold using JT02099 and JT02100 with JT03194 Caps. b. Turn compressor end for end and roll it side to side. c. Remove both plugs from manifold ports and drain solvent from compressor. d. Connect battery power to compressor clutch coil. Rotate pulley at least five revolutions to move solvent out of cylinders.
18 1830 21
7. Attach a return hose and aerator nozzle to outlet end of receiver-dryer inlet hose using JT03197 reducer. Put nozzle in container to collect flushing solvent. 8. Fill flusher tank with 4 L (1 gal) of solvent and fasten all connections.
NOTE: Air pressure must be at least 620 kPa (6.2 bar) (90 psi) for flushing and purging. 9. Connect a supply line of moisture-free compressed air or dry nitrogen to flusher air valve.
e. Invert compressor, roll end for end, and side to side. Drain thoroughly.
10. Open air valve to force flushing solvent into condenser circuit. Flusher tank is empty when hose pulsing stops. Additional flushing cycles are required if system is heavily contaminated with burned oil or metal particles.
f. Let compressor sit inverted for three to five minutes.
NOTE: Purging the condenser circuit takes 10—12 minutes to thoroughly remove solvent.
g. Repeat previous two steps at least three times.
11. Disconnect hose from aeration nozzle to check circuit for solvent. Hold hose close to a piece of cardboard; continue purging until cardboard is dry.
4. Remove and discard receiver-dryer. 5. Divide system into two circuits:
12. Go to step 13 to flush evaporator. Go to step 22 if evaporator does not require flushing.
a. Condenser, including inlet and outlet hoses. (Steps 6—12)
13. To Flush Evaporator:
b. Evaporator, including inlet and outlet hoses. (Steps 13—26)

5. Tack weld preheated plates starting at center of bucket and working toward the outside ends.
2. Clean all joints to be welded of all foreign matter such as dirt, rust, mill scale, oil, etc. with grinders and/or solvents.
6. Final weld preheated plates starting at the center of the front edge of the bucket backing plate and working toward the outside ends.
3. 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.
31 3102 6
4. Preheat parts to be welded (both tack and final welds) to minimum of 204°C (400°F). PREHEAT 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.
Repeat this operation at back edge of loader blade. 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. 7. 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.

Hydraulic Oil Clean-Up Procedure Using Portable Filter Caddy SERVICE EQUIPMENT AND TOOLS
5. Start the filter caddy. Check to be sure oil is flowing through the filters.
Portable Filter Caddy 3658 mm (12 ft) x 3/4 in. ID 100R1 Hose with 3/4 M NPT Ends (2 used) Quick Disconnect Fittings Discharge Wand JT03297 Connector (1-1/16 M ORB x 3/4 M NPT)
Operate filter caddy approximately 15 minutes so oil in reservoir is circulated through filter a minimum of four times. Leave filter caddy operating for the next steps.
IMPORTANT: Brake system uses oil from hydraulic reservoir. Flush all lines in the brake, pilot, differential lock, and clutch cut-off system. Disassemble and clean pressure reducing valve and pilot controller. Remove and clean pilot caps from main control valve. Brake components may fail if brake system is not cleaned after hydraulic reservoir contamination. 1. If hydraulic system is contaminated due to a major component failure, remove and disassemble steering cylinders to clean debris from cylinders. 2. Install new return filter elements. IMPORTANT: To prevent cavitation of filter caddy pump, the minimum I.D. of connector is 1/2 in.
NOTE: For a failure that creates a lot of debris, remove access cover from reservoir. Drain reservoir and connect filter caddy suction line to drain port. Add a minimum of 19 L (5 gal) of oil to reservoir. Operate filter caddy and wash out the reservoir. 3. To minimize oil loss, pull a vacuum in reservoir using a vacuum pump. Connect filter caddy suction line to drain port at bottom of reservoir using connector and quick disconnect fitting. Check to be sure debris has not closed drain port. 4. Put filter caddy discharge line into reservoir filler hole so end is as far away from drain port as possible to obtain a thorough cleaning of oil.
NOTE: Filtering time for reservoir is 0.089 minute x number of liters (0.33 minute x number of gallons). Reservoir capacity is 106 L (28 gal). 6. Start the engine and run it at fast idle. IMPORTANT: For the most effective results, cleaning procedure must start with the smallest capacity circuit then proceed to the next largest capacity circuit. 7. Operate all functions, one at a time, through a complete cycle in the following order: clam, steering, bucket, and boom. Also include all auxiliary hydraulic functions. Repeat procedure until the total system capacity has circulated through filter caddy seven times, approximately 30 minutes. Each function must go through a minimum of three complete cycles for a thorough cleaning of oil.
31 3160 69
NOTE: Filtering time for complete hydraulic system is 0.158 minute x number of liters (0.6 minute x number of gallons). Complete hydraulic system capacity is approximately 256 L (67 gal) . Filtering time for machines with auxiliary hydraulic functions must be increased because system capacity is larger. 8. Stop the engine. Remove the filter caddy. 9. Install new return filter elements. 10. Check oil level in reservoir; add oil if necessary. (See Fuels and Lubricants in Group 0004.)
