General Information

Personal injury can result from contact with refrigerant. This system isunder pressure at all times, evenif the engine is not running. Heat should never be applied to a charged system.
Contact withrefrigerant can cause frost bite. Keep face and hands away to help prevent injury.
Protective gogglesmust always be worn whenrefrigerant linesare opened, even if the gauges indicate the system isempty of refrigerant.
Always use caution when a fitting is removed. Slowly loosen the fitting. If the system isstill under pressure, evacuate the system recovering the refrigerant before removing the fitting.
Personal injury or death can result from inhaling refrigerant througha lit cigarette.
Inhaling air conditioner refrigerant gas througha lit cigarette or other smoking method or inhaling fumes released from a flame contacting air conditioner refrigerant gas, can cause bodily harm or death.
Do not smoke whenservicing air conditionersor wherever refrigerant gas may be present.
Before any checks of the air conditioning and heating system are made, move the machine to a smooth horizontal surface. Lower all implements to the ground. Make sure the transmission is in neutral or park and that

the parking brake is engaged. Keepall other personnel away from the machine or where they can be seen.
• All refrigerant lines that are metal or flexible hose must be free of sharp bends. Also, do not use a refrigerant line that iskinked. Sharp bends will cause a restriction in the refrigerant flow. Restrictions in the refrigerant lines are identified by cold spots or frost on the line at the location of the restriction. Restrictionsin the lines reduce the performance and the efficiency of the system.
• The radiusof bendsin the flexible hose must never be lessthan 10 times the outside diameter of the hose.
• Do not allow the flexible hoses to come within 63.5 mm (2.50 inch) of the exhaust manifold.
• The hoses need to be inspected yearly for leaks and for hardness. Conduct a leak test on all the hoses and the lines. Refer to the Service Manual, SENR3334, "Refrigerant LeakageTest" section in testing and adjusting. Replace hoses if leaks or hardness are in the hoses. Replace hoses with new hose that is sealed and free of contaminants.
• The correct use of wrenches is very important when connections are made. The type of wrench that is used is also important. Only use wrenches that are made for use with tube type fittings. When a hose is connected or disconnected from the system, use a wrench on the fitting and use a wrench on the nut. When a metal line is connected or disconnected from the system, use a wrench on the fitting and use a wrench on the nut.
• Install protective plugsor protective caps on all components and hoses that are disconnected or removed.
• O-ring seals and O-ring seats must be in good condition. Small cuts, scratches, or particles of dirt will cause a leak in the system. Put new refrigerant oil on all newO-ring seals at the time of installation. Do not use any kind of sealant on connections.
• Dust capson the compressor block fittings are the primary seals on the air conditioning system.
• All machines should have an identification tag that specifies the refrigerant charge for the machine. The tag should be located in the operator compartment.
• If water is in the ventscheck the nonreturn valve. If water leaks from the air conditioning system, check the nonreturn valve. The nonreturn valve should have the proper position and the proper direction.
• If engine coolant is leaking into the operator compartment, check for loose clamps on the heater hoses.

the parking brake is engaged. Keepall other personnel away from the machine or where they can be seen.
When the service work isdone on the air conditioning system, it is important to keep the system clean and free from contamination. Plugsand caps must be used in order to close the components and hoseswhen the components and hoses are open. The plugs and capsprotect the system from dirt and air (moisture). Only new refrigerant oil of the correct viscosity and newrefrigerant can be added to the system. Refer to the Service Manual, SENR3334, "Refrigerant Compressor" section in this manual for the correct oil. Any other material or any other substance isconsidered noncondensable and the material will contaminate the system. Keep the work area clean.
• Dust capson the refrigerant compressor block fitting are the primary seal on the air conditioning system.
• All machines should have an identification tag in the cab that specifies the proper refrigerant charge for the machine.
When replacement or repair of components and hoses are required, perform the following procedure:
1. Remove the refrigerant charge. Refer to the Service Manual, SENR3334, "Refrigerant Recovery" section in Testing and Adjusting.
2. Remove the component or remove the hose that is being repaired or replaced. Install protective plugson componentsor hoses that are left exposed to the air.
3. Replace any damaged component or hose.
4. Use the following table in order to determine the amount of oil that is lost during individual replacements of components. Add the correct amount of oil to the compressor before the system is evacuated. No additional oil should be added to the system if the compressor is replaced at the same time asother components in the system.

Refer to the Service Manual, SENR3334, "Machine Preparation for troubleshooting" section in Testing and Adjusting before service work isperformed.
Remove the accumulator. The accumulator hasan internal oil drain hole which could become plugged. The oil could be trapped inside the accumulator. It isnecessary to check for excessive oil when the accumulator ischanged. Add the same amount of oil that was drained from the old accumulator. Add an additional 30 mL (1 fl oz) to the new accumulator before the new accumulator is installed. Do not add oil if the compressor was changed also. Evacuate the system and recharge the system. Refer to the Service Manual, SENR3334, "Refrigerant SystemEvacuate" section in Testing and Adjusting. Refer to the Service Manual, SENR3334, "Refrigerant System - Charge" section in Testing and Adjusting.
Note: If the accumulator hasfrost on the outside, the air conditioning system still contains refrigerant.

To replace the expansion valve, use the procedure that follows. Refer to Service Manual, SENR3334, "Troubleshooting Heating and Air Conditioning Control System" before service work isperformed on the air conditioning system.
1. Recover the refrigerant.
Note: Cap all disconnected lines and hoses.
2. Remove the insulation and the clip. The insulation and the clip hold the sensing bulb to the evaporator outlet pipe.
3. Disconnect the sensing line for pressure from the evaporator outlet pipe.
4. Loosen and remove the two connections at the expansion valve. Remove the expansion valve.
Note: Check the O-ring seals. The seals must be in good condition and the seals must be properly lubricated with the correct refrigerant oil before assembly.
5. Install the expansion valve for replacement and tighten the two connections.
6. Tighten the pressure sensing connection on the evaporator outlet pipe.
7. Use a 8P-6355 Clip to hold the sensing bulb onto the evaporator outlet pipe. The sensing bulb should be as close to the coil as possible. The bulb should be upstream of the pressure sensing connection on the evaporator outlet pipe. The 5P-7070 Insulation should be wrapped tightly around the clip, the sensing bulb and the outlet pipe. There should be no insulation between the bulb and the outlet pipe.
8. Tighten all the connections correctly.
9. Evacuate the system. Refer to the Service Manual, SENR3334, "Refrigerant SystemEvacuate" section in testing and adjusting.
10. Charge the system with the correct amount of refrigerant by weight. Refer to the Service Manual, SENR3334, "Refrigerant System - Charge" section in testing and adjusting.
