Air Conditioning Compressor Replacement

A new compressor is supplied filled with a full charge (X cu. cm) of refrigerant oil.

A calculated quantity of oil must be drained from the new compressor before fitting. To calculate the quantity of oil to be drained:
1 Remove the drain plug from the old compressor.
2 Invert the compressor and gravity drain the oil into a calibrated measuring cylinder. Rotate the compressor clutch to ensure the compressor is completely drained.
3 Note the quantity of oil drained (Y cu. cm).
4 Calculate the quantity of oil to be drained from the new compressor using the following formula:

X cu. cm - (Y cu. cm + 20 cu. cm) = Q cu. cm

5 Remove the drain plug from the new compressor and drain Q cu. cm of oil. Fit and tighten the compressor drain plug.
