COMPRESSOR
COMPRESSOR
General PrecautionsINFOID:0000000003884820
CAUTION:
 Plug all openings to prevent moisture and foreign matter from entering.
 Store it in the same way at it is when mounted on the car when the compressor is removed.
 Follow “Maintenance of Lubricant Quantity in Compressor” exactly when replacing or repairing the
compressor. Refer to HA-28, "
Maintenance of Lubricant Quantity".
 Keep friction surfaces between clutch and pulley clean. Wipe it off by using a clean waste cloth
moistened with thinner if the surface is contaminated with lubricant.
 Turn the compressor shaft by hand more than five turns in both directions after compressor service
operation. This equally distributes lubricant inside the compressor. Let the engine idle and operate
the compressor for one hour after the compressor is installed.
 Apply voltage to the new compressor and check for normal operation after replacing the compressor
magnet clutch.
