RADIAL 4 CYLINDER COMPRESSOR
Component Replacement
When replacing a system component, oil should be added to the system as follows. If compressor is operating, idle engine for 10 minutes with A/C controls set for maximum cooling and high blower prior to discharging system.
Add additional oil as specified if any of components are replaced.
Condenser 1 ounce
Evaporator 1 ounce
VIR 3 ounce
Accumulator 1 ounce
Compressor Replacement
1. Discharge system and remove compressor from vehicle.
2. Position compressor with shaft end up and allow oil to drain from suction and discharge ports into a container calibrated in ounces.
3. Drain oil from new compressor, then add same amount of new refrigerant oil to new compressor as was drained from original compressor. If system was flushed the total oil capacity must be added to the compressor as specified in the A/C Data Table.
4. Install new compressor and charge system.
Component Rupture, Fast Discharge
1. Repair leak and flush system.
2. Remove compressor and drain oil.
3. Add total capacity as specified in A/C Data Table of new refrigerant oil to suction port of compressor.
4. Install compressor, charge system and perform leak check.
Slow Leak
1. If refrigerant loss has occurred over an extended period of time, add 3 ounces of refrigerant oil to system.
2. Recharge system.
System Performance Evaluation
When system performance, efficiency and proper oil charge are in doubt, the system should be flushed and the total capacity, as specified in the A/C Data Table, of new refrigerant oil be added to the compressor prior to any further checks of the system.

AXIAL 6 CYLINDER COMPRESSOR
Oil Charge
1. Idle engine for 10 minutes at 1250 RPM with system controls set for maximum cooling and high blower speed.
2. Stop engine, discharge system and remove compressor.
3. With compressor in a horizontal position and drain plug down, remove plug and drain oil into a measured container.
4. If 4 ounces or more of oil was drained, add the same amount to the compressor. If less than 4 ounces of oil was drained, add 6 ounces of oil to compressor.
Compressor Replacement
1. Idle engine for 10 minutes at approximately 1250 RPM at maximum cooling and high blower speed to distribute oil in system.
2. Remove compressor from vehicle.
3. Remove plug and allow oil to drain from compressor into a container calibrated in ounces.
4. Drain oil from new compressor.
5. If amount drained from original compressor is more than four ounces, add the same amount of new refrigerant oil to the new compressor plus amount lost during discharge.
6. If amount of oil drained from original compressor is less than 4 ounces, add 6 ounces of new refrigerant oil to the new compressor plus amount lost during discharge.
Component Replacement
Whenever a component of the A/C system is replaced, and the component is not pre-charged at the factory, measured quantities of refrigeration oil should be added to the component to assure that the total oil charge in the system is correct before the system is placed into operation.
The oil is poured directly into the replacement component. If an evaporator is installed, pour oil into the inlet pipe with the pipe held vertically so the oil will drain into the evaporator core. No additional oil is required if valves and hoses are replaced.
Add additional oil as specified if any of the following components are replaced.
Evaporator 3 ounces
Condenser 1 ounce
VIR 1 ounce
Accumulator 1 ounce
Receiver 1 ounce
If the system is flushed with a sufficient amount of a flushing agent that would remove oil from the system, install the full amount specified in the A/C Data Table. On a newly installed system, install the full capacity of oil prior to operation. On systems containing metal particles in the oil, flush the system, replace or overhaul the compressor, replace receiver-dehydrator or VIR desiccant, and install a high capacity, low pressure drop filter in the liquid line to protect the expansion valve and new compressor from damage due to foreign particles.
