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.

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.

–UN–23AUG88

Check Oil Lines And Fittings

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.

Service Recommendations For Inch Series Four Bolt Flange Fittings

A—Sealing Surface

B—Split Flange

C—Pinched O-Ring

1. Clean sealing surfaces (A). Inspect. Scratches cause leaks. Roughness causes seal wear. Out-of-flat causes seal extrusion. If defects cannot be polished out, replace component. 2. Install O-ring (and backup washer if required) into groove using petroleum jelly to hold it in place. 3. Split flange: Loosely assemble split flange (B) halves. Make sure split is centrally located and perpendicular to port. Hand tighten cap screws to hold parts in place. Do not pinch O-ring (C). 4. Single piece flange (D): Place hydraulic line in center of flange and install cap screws. Flange must be centrally located on port. Hand tighten cap screws to hold flange in place. Do not pinch O-ring. 5. Tighten one cap screw, then tighten the diagonally opposite cap screw. Tighten two remaining cap screws. Tighten all cap screws as specified in the chart below.

then tighten the diagonally opposite cap screw. Tighten two remaining cap screws. Tighten all cap screws as specified in the chart below.

1. Clean sealing surfaces (A). Inspect. Scratches cause leaks. Roughness causes seal wear. Out-of-flat causes seal extrusion. If defects cannot be polished out, replace component.

DO NOT use air wrenches. DO NOT tighten one cap screw fully before tightening the others. DO NOT over tighten.

2. Install the correct O-ring (and backup washer if required) into groove using petroleum jelly to hold it in place.

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.

17 1740 2

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.

Windowpanes Repair 2. Scrape any broken glass off existing adhesive. DO NOT remove adhesive from window frame or cab.

Remove and Install Windowpanes The adhesive used to secure windowpanes is a urethane adhesive used on automobile windshields. Urethane adhesive manufactured by Loctite Corporation or equivalent is recommended. DO NOT use any other type of adhesive. It is recommended that an auto glass dealer install windowpanes. IMPORTANT: Windowpanes must include an ultra-violet barrier around edge so adhesive will not deteriorate. Windowpanes ordered through John Deere Parts have this ultra-violet barrier. If windowpane is purchased through glass dealer, the dealer must incorporate an ultra-violet barrier on the glass. DO NOT paint border of glass. If auto glass dealer does not install windowpanes, proceed as follows: 1. Remove windowpane frame from cab.

IMPORTANT: Adhesive will not stick to bare metal. 3. If existing adhesive is removed and paint is scraped, paint window frame. Paint must be fully cured before installing windowpane. 4. Trim existing adhesive to form a smooth surface. IMPORTANT: Follow manufacturer’s instructions for using adhesive. 5. Apply 6 mm (1/4 in.) bead of adhesive over existing adhesive. 6. Position windowpane in cab frame. Use hand pressure to force windowpane down until edges are even with metal frame. 7. Secure windowpane with duct tape until adhesive cures. Allow adhesive to cure for 24 hours before operating machine.

Heating and Air Conditioning Refrigerant Cautions and Proper Handling 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.

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.

Use correct refrigerant recovery, recycling and charging stations. Never mix refrigerants, hoses, fittings, components or refrigerant oils.

DO NOT allow refrigerant to contact open flames or very hot surfaces such as electric welding arc, electric heating element and lighted smoking materials.

Use only John Deere approved R134a refrigerant products. Mixing of products not compatible will cause system damage and contaminate recovery, recycling and charging station equipment. Care must be taken to identify and use equipment, refrigerant oil and refrigerant designed only for R134a refrigerant systems. Refrigerant should be tested for type and purity before recovery, recycling or charging of system. JT02167A refrigerant test instrument should be used before any testing or repair to system is preformed.

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. IMPORTANT: To meet government standards relating to the use of refrigerants,

R134a Refrigerant Oil Information 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. IMPORTANT: Do not add any more oil than required or maximum cooling will be reduced. DO NOT leave system or R134a compressor oil containers open. Refrigerant 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. A new compressor from parts depot contains new oil. The oil level visible through the suction port normally is below the drive shaft.

18 1830 6

Refrigerant Oil Capacity—Specification Oil—Volume ............................................................ 210 mL (7.1 fl oz) R134a—Weight.............................................. 850 ± 50g (1.9 ± 0.1 lb)

If any section of hose is removed and flushed or replaced, measure length of hose and use formula 3 mL per 30 cm (0.1 fl oz per ft ) to determine correct amount of oil to be added. Drain compressor oil into graduated container while rotating compressor shaft and record amount. If oil drained from a compressor removed from operation is very black or amount of oil is less than 6 mL (0.2 fl oz), perform the following and discard oil properly: ❒ Determine if R134a leakage was detected, remove component and repair or replace component. ❒ Remove and discard receiver/dryer. ❒ Flush complete system with TY16134 Air Conditioning Flushing Solvent. If component is serviceable, pour flushing solvent in ports and internally wash out old oil and discard oil properly.

Normal operating oil level of a compressor removed from operation cannot be seen through suction port of compressor.

Install a new receiver-dryer. See Receiver-Dryer Repair. (See procedure in this group.)

Compressors can be divided into three categories when determining correct oil charge for system.

Install required amount of TY22025 Refrigerant Oil in compressor.

• New compressor from parts depot • Used compressor removed from operation • Compressor internally washed with flushing solvent

Connect all components, evacuate and charge system. See Evacuate R134a System and Charge R134a System. (See procedures in this group.)

Determining the amount of system oil charge prior to installation of compressor on a machine. When complete system, lines, and components are flushed add correct amount of oil as described.

Hydraulic Pump and Drive Gearbox Start-Up Procedure IMPORTANT: Hydraulic pump and drive gearbox will be damaged if not filled with oil before starting engine. Procedure must be performed whenever a new pump or gearbox is installed or oil has been drained from the pump, gearbox or hydraulic oil tank. Procedure is to ensure the pumps and gearbox are filled with oil and air is bled from suction side of pumps to prevent cavitation.

–UN–15JUL96

1. Remove air bleed plugs (C) from the top of pump regulators to allow housing to fill with oil from the hydraulic oil tank and to let air escape. 2. When pump housing is full of oil, install plugs.

4. Start engine and run at slow idle. Slowly raise boom to full height and then lower to pressurize hydraulic oil tank.

T101875

3. As necessary, add oil to hydraulic oil tank until it is between marks on sight glass. See Hydraulic Oil. (Operator’s Manual). Tighten tank cap. Tighten vent plug. C—Air Bleed Plug (2 used)

5. Purge air from the hydraulic system by slowly operating each function through three cycles. Air in pilot circuits are purged automatically.

33. Check the 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. 34. 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 the 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 the taper against cap seal. Before tightening the hose clamp, check to be sure tie band is under hose clamp all around piston.

35. Check the 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. 36. 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 the 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 the taper against cap seal. Before tightening the hose clamp, check to be sure tie band is under hose clamp all around piston.

Hydraulic Cylinder Bleed Procedure IMPORTANT: Trapped air suddenly compressed in a cylinder is heated and ignites the oil used for assembly causing cap seal and ring damage. Start with cylinder rod retraced and the rod end filled with clean oil. Connect the cylinder head end and lines. Operate function to slowly extend rod. Procedure will eliminate most of the air and reduce the possibility of damage.

NOTE: Bleed air at initial start-up, whenever major repairs or maintenance (oil change) is done on hydraulic system, or when machine has been in storage for a period of time. 1. Run engine at slow idle. 2. Slowly operate function to move cylinder to the most horizontal position possible. 3. Slowly extend and retract cylinder several times to approximately 100 mm (4 in.) from end of stroke. 4. Operate cylinder several times to full stroke. 5. Check hydraulic oil level. See Check Hydraulic Oil Level. (Operator’s Manual.)
