Air Conditioning Compressor Oil Balancing

Air Conditioning Compressor Oil Balancing (With HP5)

Special Tools
* J 45037 - A/C Oil Injector
* GE 48997 - Hybrid A/C Oil Injector Adaptor Hose

Draining Procedure

Note: Drain and measure as much of the refrigerant oil as possible from the removed compressor.

1. Drain the oil from both the suction and discharge ports of the removed compressor into a clean, graduated container.




2. Measure and record the amount of oil drained from the removed compressor. This measurement will be used during installation of the replacement compressor.
30ml (1oz) of POE refrigerant oil will remain in the compressor after draining. This amount should be considered when calculating the amount of oil needed to replenish the system.

Note: During the oil removal procedure, the condition of the oil should be evaluated. Compressor oil never breaks down unless something is wrong with the compressor or air conditioning (A/C) system. If one or more of the following conditions exist, replace the compressor and receiver dehydrator.

3. Inspect oil drained from removed compressor. Refer to Air Conditioning Compressor Oil Diagnosis (Air Conditioning Compressor Oil Diagnosis)
4. Properly discard the used refrigerant oil.

Balancing Procedure

Note: The refrigerant oil in the A/C system must be balanced during compressor replacement.

1. The replacement compressor is shipped with 74 ml (2.5 oz) of refrigerant oil.




2. Before installing the compressor, calculate the total amount of oil drained from the compressor and collected by the recovery equipment.
3. If the amount drained and recorded is:

* LESS THAN 74ml (2.5 ounces), leave 74ml (2.5 ounces) in the replacement compressor. Do not drain the oil from the replacement compressor.
* MORE THAN 74ml (2.5 ounces), calculate the difference between the amount that was drained and recorded. ADD the calculated difference to the A/C system using J 45037 - injector along with GE 48997 - adapter.
