(4) Insert the two pins of the spanner wrench into
two holes of the clutch plate. Hold the clutch plate
stationary and remove the bolt that secures the
clutch plate to the compressor shaft.
(5) Remove the clutch plate (Fig. 27).
(6) Remove the external snap ring from the front
compressor housing hub with snap ring pliers and
remove the clutch rotor and bearing assembly (Fig.
28).
(7) Remove the screw and retainer from the clutch
coil wire harness on the compressor front housing.
(8) Remove the snap ring from the compressor hub
and remove the clutch field coil (Fig. 29). Slide the
clutch field coil off of the compressor hub.
INSPECTION
Examine the friction surfaces of the clutch drive
plate and the clutch plate for wear. The drive plate
and clutch plate should be replaced if there is exces-
sive wear or scoring.
If the friction surfaces are oily, inspect the shaft
and nose area of the compressor for oil. Remove the
felt from the front cover. If the felt is saturated with
oil, the shaft seal is leaking and the compressor must
be replaced.
Check the clutch drive plate bearing for roughness
or excessive leakage of grease. Replace the bearing, if
required.
INSTALLATION
(1) Align the dowel pin on the back of the clutch
field coil with the hole in the compressor front hous-
ing and press the field coil into place.
(2) Install the clutch coil wire lead retaining clip
on the compressor front housing and tighten the
retaining screw.
(3) Install the clutch field coil and snap ring with
snap ring pliers. The bevel side of the snap ring must
be facing outward. Press the snap ring to make sure
it is properly seated in the groove.
CAUTION: If the snap ring is not fully seated in the
groove it will vibrate out, resulting in a clutch fail-
ure and severe damage to the front housing of the
compressor.
(4) Check that the original clutch spacer shims are
in place on the compressor shaft and install the
clutch plate. Replace the shaft bolt and tighten to
14.4 N·m (10.5 ft. lbs.).
NOTE: The clutch air gap is determined by the
spacer shims. When installing the original or a new
clutch assembly, try the original shims first. When
installing a new clutch onto a compressor that pre-
viously did not have a clutch, use 0.040, 0.020, and
0.005 in. shims from the clutch accessory sack.
(5) Check the air gap with a feeler gauge (Fig. 30).
If the air gap does not meet the specification add or
