CLUTCH BEARING
When installing a new bearing,
extreme care must be taken to support
the bearing and the clutch assembly
so as not to place any pressure on the
balls of the bearing.
The following procedure should
be rigidly adhered to during bearing
replacement.
Any exceptions due to
clutch design are noted. Refer to
Fig.
25
.
Removal
1. Remove the clutch assembly
from the compressor shaft as outlined
in the foregoing procedure.
2.
With the clutch assembly face
down, remove the external bearing
retainer from the drive plate shaft.
3. Support the
clutch,
face down,
by the outer edge so as to clear the
drive plate. Insert a 5/8-11 inch bolt
through the drive plate shaft and
hand tighten the bolt.
4. Smoothly apply enough pres-
sure on the bolt to free the shaft
from the bearing inner race and then
remove the drive plate assembly.
Before proceeding, check the drive
face plate for any excessive warping
or
breakage. Replace the entire
clutch assembly if any damage is
evident.
S. Remove the internal bearing
retainer from the pulley assembly
.
Support the pulley assembly, face
up,
by the bearing bore making
certain that there is no interference
when the bearing is pressed out. With
a suitable plug, force the bearing out
of the pulley assembly by the inner
race. The plug should clear the metal

Installation
Before installing the bearing, be
sure that all bearing contact surfaces
are clean.
1. Support the pulley assembly
face down, near the bearing bore but
do not support it by the sides of the
pulley grooves as this may bend the
pulley assembly.
2. Press a new bearing into the
bearing bore by the outer race. Do
not press the bearing in by the inner
race. Pressure should be uniform and
in line with the axis of the bearing
bore. Replace the internal bearing
retainer.
3. Support the pulley assembly,
face up, by the bearing inner race
.
Insert a 5/8-11 inch bolt, into the
front of the drive face plate and care-
fully press the shaft into the bearing
inner race, exerting pressure on the
bolt. Be certain that the shaft is in
line with the axis of the bearing bore.
4. Replace the external bearing
retainer onto the drive plate shaft.
Rotate the pulley relative to the drive
plate to make certain that there is
free rotation and that there is no
looseness of the assembly before
installing the clutch onto the com-
pressor.
S. Install the clutch on the com-
pressor shaft.
