AIR CONDITIONER COMPRESSOR SERVICE - CONTINUED
GENERAL INFORMATION - CONTINUED
Air conditioning system should have approximately 14 fl oz (414 ml) of refrigerant oil. There should be 10 fl oz (296
ml) in compressor.
Each major component has approximately 2 fl oz (59 ml) of refrigerant oil. Therefore, additional oil must be added to
compressor when a major component is replaced.
If condenser and receiver-drier are to be replaced, first check oil level in compressor. Compressor should have 10 fl oz
(296 ml). Add oil if needed. Then, after replacing condenser and receiver-drier, add an additional 4 fl oz (118 ml) of oil
to compressor. Entire system should then have approximately 14 fl oz (414 ml).
DO NOT remove air conditioner compressor oil fill plug without first recovering refrigerant from sys-
tem. Failure to recover system could cause uncontrolled release of high pressure refrigerant, which can
freeze skin and eye tissue causing serious injury or blindness.
Use care to prevent refrigerant from touching your skin or eyes. Liquid refrigerant, when exposed to air,
quickly evaporates and will freeze skin or eye tissue. Serious injury or blindness may result if you come
in contact with liquid refrigerant.
Remove oil fill plug (1) and preformed packing from compressor (2). Retain preformed packing if not damaged or if
there are no signs of leaks.
Use oil level gage to check oil level in compressor (2).
If gage bottoms out before going in more than 3 in (7.6 cm), it is hitting compressor crankshaft. Rotate drive plate
by hand and insert gage until it contacts bottom of sump.
