24 - 2 HEATING & AIR CONDITIONING
A/C COMPRESSOR (Continued)
This condition is the result of normal refrigerant
movement within the A/C system caused by temper-
ature changes. The refrigerant movement may wash
the oil out of the compressor.
REMOVAL
The compressor may be removed from the mount-
ing bracket and repositioned without disconnecting
the refrigerant lines or discharging the refrigerant
system. Discharging is not necessary if servicing the
compressor clutch or clutch coil, the engine, the cyl-
inder head or the generator.
