MC-9 MAINTENANCE MANUAL
pressor crankshaft, the compressor begins operating when
the pulley transmits its rotation to the armature.
The compressor will operate as long as the clutch field
coil remains energized - armature and rotor magnetically
coupled. When the field coil is de-energized, the armature
is pulled back, out of contact with the rotor (by spring tabs)
and the armature (and compressor shaft) ceases rotation.
NOTE: A housing-mounted clutch has 6
mounting nuts on the armature; a shaft-
mounted clutch does not have these 6
nuts.

MAINTENANCE - If the compressor clutch is mounted on
the compressor shaft (figure 16-47), the clutch bearing has
no provision for lubrication. Maintenance of this unit is
limited to inspecting the clutch for wear, replacing the
clutch as required, and checking the resistance of the coil
winding. For shaft-mounted compressor clutch, perform
the following procedure; if clutch is housing-mounted, skip
this procedure and perform the subsequent maintenance
procedure (Housing-Mounted Clutch Maintenance).
1. For the shaft-mounted clutch, clean all dirt and grease
from the clutch armature plate. Take care not to allow the
foreign m;lterial to be displaced into the armature slots and
between clutch faces.
2. With compressed air, blow all dirt out from clutch fac-
ing area.
