ISSUE:
When replacing the FX-15 compressor it is very important to accurately match the amount of oil being replaced. Some dealerships have indicated that they are unable to properly match the amounts of oil being replaced.
ACTION:
Replace the amount of oil being drained from the FX-15 compressor with an equal amount of new oil, to assure proper compressor operation. Refer to the following service procedure for service details.
SERVICE - PROCEDURE
1. Remove as much oil as possible from the compressor. The compressor shaft should be rotated about six to eight revolutions allowing the oil to drain from the compressor ports.
a. Obtain a clean container that can be also used as a measuring device.
b. Place the disc and hub assembly on the compressor shaft so the shaft can be rotated.
c. Rotate the shaft by hand (6) six to (8) eight revolutions allowing the oil to drain from the ports, while collecting the oil in the clean measuring device.
NOTE:
SERVICE COMPRESSORS COME PRE-CHARGED WITH 7 OUNCES OF OIL
2. If the amount of oil drained from the old compressor is between (3) three and (5) five fluid ounces, pour the same amount of clean Motorcraft YN-9 refrigerant oil into the new compressor.
3. If the amount of oil that was removed from the old compressor is greater than (5) fluid ounces, pour five ounces of clean Motorcraft YN-9 refrigerant oil into the new compressor.
4. If the amount of refrigerant oil that was removed from the old compressor is less than (3) three fluid ounces, pour three fluid ounces of clean Motorcraft YN-9 refrigerant oil into the new compressor.
NOTE:
THE SUCTION/ACCUMULATOR-DRYER AND ORIFICE TUBE MUST BE REPLACED WHENEVER THE COMPRESSOR IS REPLACED.
