Safety

Avoid Static Electricity Risk When Refueling The removal of sulfur and other compounds in Ultra-Low Sulfur Diesel (ULSD) fuel decreases its conductivity and increases its ability to store a static charge. RG22142 —UN—17MAR14

Refineries may have treated the fuel with a static dissipating additive. However, there are many factors that can reduce the effectiveness of the additive over time. Static charges can build up in ULSD fuel while it is flowing through fuel delivery systems. Static electricity discharge when combustible vapors are present could result in a fire or explosion.

RG21992 —UN—21AUG13

Therefore, it is important to ensure that the entire system used to refuel your machine (fuel supply tank, transfer pump, transfer hose, nozzle, and others) is properly grounded and bonded. Consult with your fuel or fuel system supplier to ensure that the delivery system is in compliance with fueling standards for proper grounding and bonding practices.

Stud end threads are identified as metric by an identification groove in the hex nut next to the O-ring.

b

Straight hex size applies to fittings only and may not be the same as the corresponding plug of the same thread size.

1. Inspect fitting and connector sealing surfaces and the O-rings. They must be free of dirt, scratches, nicks, and burrs. O-ring must be free of dirt, cuts, cracks, swelling, or flatten condition. 2. Back the stud end hex nut off as far as possible. Push backup washer towards the nut to fully expose the turn down section. Washer must fit turned down section and not be too loose.

To protect an O-ring from threads, wrap electrical tape over the threads. Slide O-ring over the tape into the turned down section. Remove the tape. 4. Turn fitting into the boss by hand until face of nut or washer squeezes the O-ring into the seat and contacts face of boss. Loosen adjustable fittings no more than one turn for alignment. Hold connections together while tightening nut to ensure O-ring remains in place.

3. Lubricate O-rings using a thin film of clean hydraulic oil or as needed, petroleum jelly to hold O-ring in place. Install O-ring into groove making sure it is seated at the bottom. Excess petroleum jelly will prevent seating of O-ring and cause it to pop out.

5. Tighten fitting or nut to torque value shown. Use a second wrench to hold the fitting in position or to keep hose from twisting while tightening nut. OUT3035,0000421 -19-04MAR16-2/2

NOTE: These fittings are also referred to as EO and EO-2 Bite Type or Ermeto style fittings. T113889 —UN—15APR13

IMPORTANT: In this style of fittings, there are “heavy” and “light” designs. Usually “heavy” is used for pressure lines and “light” for return lines. Some “heavy” and “light” sizes can be threaded together but do not seal properly. Be sure not to mix “heavy” and “light” fittings. 1. Inspect the fitting sealing surfaces. They must be free of dirt scratches, nicks, and burrs.

Connection

2. Inspect the O-ring. It must be free dirt, cuts, cracks, swelling or flatten condition. 3. Lubricate O-rings using a thin film of clean hydraulic oil. 4. Align an adjustable fitting with the tube.

Hold connections together while tightening nut to ensure proper seal. 5. Tighten nut (A) hand tight so O-ring contacts seat and then an additional 1/4—1/3 turn using a wrench. CED,OUO1002,517 -19-14JAN04-1/1

25— Angular

26— Lateral

This procedure is to be performed whenever the exhaust tube or exhaust bellows is disconnected. The JDG11335 Bellows Alignment Fixture is used to hold the exhaust bellows at nominal alignment. While the exhaust bellows is held at nominal alignment, it allows the technician to visually see and measure to verify that the exhaust bellows is in alignment with the exhaust filter. The life of the bellows depends on how well the exhaust bellows is aligned axially (24), angularly (25), and laterally (26). Axial tolerance is ±6.4 mm (±0.252 in.), angular tolerance is 2°, and lateral tolerance is ±8.5 mm. (±0.335 in.). Use

the adjustable frame with the adjustment points to align the exhaust bellows with the exhaust filter inlet. 1. Park and prepare machine for service. See Park and Prepare for Service Safely. (Group 0001.) 2. Assemble JDG11335 Bellows Alignment Fixture. See JDG11335 Bellows Alignment Fixture. (Group 0530.) 3. Remove selective catalyst reduction (SCR) assembly.

Frame Installation Welding on Machine CAUTION: Do not weld or apply heat on any part of a reservoir or tank that has contained oil or fuel. Heat from welding and cutting can cause oil, fuel, or cleaning solution to create gases which are explosive, flammable, or toxic. Avoid welding or heating near pressurized fluid lines. Flammable spray may result and cause severe burns if pressurized lines fail as a result of heating. Do not let heat go beyond work area to nearby pressurized lines. 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. When sanding or grinding painted surfaces, avoid breathing the dust. Wear an approved respirator. If using 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.

• When sanding or grinding paint, avoid breathing the dust.

• Wear an approved respirator. When using 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.

IMPORTANT: Avoid machine damage to diesel exhaust fluid (DEF) system. After key switch is switched to OFF position, wait at least 10 minutes before turning battery disconnect switch to OFF position or disconnecting battery cables. During cold-weather exposure, if adequate time is not allowed for lines to be purged, residual DEF can freeze and possibly damage components of the DEF system. IMPORTANT: Electrical current traveling from the welder through the machine electrical system may damage the machine electrical system, including battery and control units. Disconnect battery positive and negative cables before welding on machine. 2. Disconnect the negative (-) battery cable(s).

3. Disconnect the positive (+) battery cable(s). 4. Cover, protect, or move any wiring harness sections away from welding area. IMPORTANT: Have only a qualified welder perform this job. Connect welder ground clamp close to each weld area so electrical current does not pass through any bearings, articulation joints, or pivot points. Remove or protect all parts that can be damaged by heat or weld splatter. 5. Connect welder ground close to welding point and away from control units. 6. Use one of the following weld processes:

• AWS-E-7018 covered electrode with shielded metal arc welding (SMAW) process.

• 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.

IMPORTANT: Avoid poor weld penetration. Preheat area that will be repaired to allow better weld penetration. Poor weld penetration can lead to further damage. 7. To repair weld metal failure, remove failed weld metal using arc gouging 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).

Windowpanes Remove and Install

NOTE: Adhesive will not stick to bare metal.

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 recommended that an auto glass dealer install windowpanes. IMPORTANT: Windowpanes must have an ultraviolet barrier around edge of glass since ultraviolet rays will deteriorate adhesive. Windowpanes ordered through John Deere Parts have the ultraviolet barrier. If windowpane is purchased through a glass dealer, dealer must put an ultraviolet barrier on glass. Do not apply paint to border of glass. If an auto glass dealer is not installing windowpanes, use following procedure: 1. Park and prepare machine for service safely. See Park and Prepare for Service Safely. (Group 0001.)

NOTE: Paint must be fully cured before installing windowpane. 3. 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. 4. Trim existing adhesive so it has a smooth surface. 5. Follow manufacturer’s instructions for using adhesive. 6. Apply 6 mm (1/4 in.) bead of adhesive on top of the existing adhesive. 7. Install new windowpane. Use hand pressure to force windowpane down around the edges. 8. Apply duct tape to hold windowpane in place while adhesive cures. 9. Allow adhesive to cure for 24 hours before operating machine.

2. Scrape broken glass off existing adhesive. Do not remove adhesive from window frame or cab. JN86345,00000E3 -19-10JAN13-1/1

Heating and Air Conditioning R134a Refrigerant Cautions and Proper Handling

If skin freezes to container, pour COOL water over container to free the skin. Go to a physician or hospital immediately for treatment.

SERVICE EQUIPMENT AND TOOLS Refrigerant Identifier

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.

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. Use correct refrigerant recovery, recycling, and charging stations. Do not 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. Refrigerant identifier should be used before any testing or repair to system is performed.

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 bare hands. Skin may freeze to container. Wear gloves.

OTHER MATERIAL KJD10575 R134a Compressor Oil

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

If installing a new compressor, make sure oil level is visible through suction port. Oil level is normally below drive shaft.

e. Install new receiver-dryer. See Receiver-Dryer Remove and Install. (Group 1830.)

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

6. Install compressor. See Air Conditioner Compressor Remove and Install. (Group 1830.)

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

IMPORTANT: Prevent possible air conditioning system damage. Do not add any more oil than required or maximum cooling will be reduced.

• New compressor • Used compressor removed from operation • Compressor internally washed with flushing solvent CAUTION: Avoid possible injury. All new compressors are charged with a mixture of nitrogen, R134a refrigerant, and R134a refrigerant oil. Wear safety goggles and discharge compressor slowly. 1. Handle refrigerant carefully. See R134a Refrigerant Cautions and Proper Handling. (Group 1830.) 2. Park and prepare machine for service safely. See Park and Prepare for Service Safely. (Group 0001.) 3. Remove and repair or replace compressor. See Air Conditioner Compressor Remove and Install. (Group 1830.) 4. Drain oil into graduated container while rotating compressor shaft if a new compressor is required. 5. Record measured oil and discard oil properly. If oil drained from a compressor removed from operation is very black or amount of oil is less than specification, perform the following:

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. 7. Add required amount of R134a compressor oil. 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.

Hydraulic Cylinder Bleed Procedure

hydraulic system, or when machine has been in storage for a period of time.

SPECIFICATIONS Engine Speed

Slow Idle

CAUTION: Prevent injury from unexpected machine movement. Perform this procedure when repairs or maintenance is done on hydraulic system, or when machine has been stored for a period of time. 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 retracted 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.

IMPORTANT: Prevent component damage from cavitation. Perform this procedure when repairs or maintenance is done on hydraulic system, or when machine has been stored for a period of time. 1. Operate engine to specification. Specification Engine—Speed..........................................................................Slow Idle

2. Slowly extend and retract cylinder several times to approximately 100 mm (4 in) from end of stroke. 3. Operate cylinder several times to full stroke. 4. Check hydraulic oil level. See Check Hydraulic Tank Oil Level. (Operator’s Manual.)

NOTE: Bleed air at initial start-up, whenever major repairs or maintenance (oil change) is done on JL58967,00002B2 -19-12MAY15-1/1
