Air Conditioning Compressor Oil Balancing

Oil Charge Requirement

All SP17 Compressors are supplied with 150 ±10 cc oil charged in the compressor.

Care must be taken to ensure that the required oil quantity should be charged into the A/C system. Shortage of oil will cause compressor durability problems. Excessive oil in the system can result in knocking noise at start up of the compressor.

Compressor Oil Balancing Procedure

Compressor oil can be charged and drained through the Suction/Discharge Ports. When a compressor is removed from the car for service, there are two methods to correctly oil-balance the air-conditioning system:

Note: If major oil loss has occurred such as compressor case cracked, condenser rupture, flush A/C system and fit new replacement compressor. No lubricant check required.

•	First Method

1.	Flush entire A/C system.

2.	Install a complete new SP17 compressor, which is already charged with 150 cc oil.

•	Second Method

1.	Drain and measure lubricating oil from the removed compressor. Measure the amount removed. (Usually, in the SP17 compressor there should retain an amount of 15-60 cc of oil).

2.	Remove all of the lubricating oil from the new replacement compressor, approximately 150 cc.

3.	Refill the new replacement compressor with the same amount of lubricating oil as measured in Step One. Use the "new" oil removed from the replacement compressor.
