-
remove oil drain plug from new compressor
Note
Replacement A/C compressors supplied by the Parts Department are filled with 250 cc +/- 20 cc (8.5 fl oz +/- 0.7 fl oz) of refrigerant oil. This is The
total system oil capacity.
-
drain fresh oil from new compressor and save (keep oil in an enclosed container to prevent moisture and dirt contamination)
CAUTION
In order to ensure lubrication during initial start-up add a minimum of 80 cc (2.7oz) of fresh refrigerant (PAG) oil to A/C compressor.
-
refill new compressor with 80 cc (2.7 oz) of fresh refrigerant oil
-
install oil drain plug
If total amount of refrigerant oil drained from old compressor was greater than 80 cc (2.7 oz),
-
subtract 80 cc (2.7 oz) (amount of new oil that was added to compressor) from total amount
-
add resulting amount of fresh refrigerant oil to either evaporator or accumulator
Example:
100 cc (amount of oil drained from old compressor)
-80 cc (amount of fresh oil added to new compressor)
= equals =
20 cc (amount of fresh oil to be added to evaporator or accumulator)
Note
Some refrigerant recovery/recycling/recharging equipment has provisions for adding refrigerant (PAG) oil during system recharge. If using this method
for adding oil, follow all refrigerant/recovery/recycling/recharging equipment manufacturer's instructions.
