Diagnosis for Noisy Clutch
Spin the pulley by hand. There must be no inter
ference between the field and the rotor assembly. The
clutch coil must be mounted properly using the special
capscrews which position the field coil to the
compressor.
A worn pulley bearing can be detected by the rough
ness felt when spinning the pulley. Do not attempt to
replace the bearing. Replace the clutch as an assembly.
A replacement clutch may emit a short squeal when
initially engaged. After a few cycles of operation, the
noise will disappear.
