the puller. If the drive clutch will not
release, sharply strike the head of the

5. Remove the clutch from the engine com-
partment.
CHECKING BEARING WEAR
The clearance between the hex shaft and bear-
ing is critical for correct drive clutch operation.
The flats on the drive clutch are directly
associated with the large bearing area.
The maximum allowable bearing wear is
limited by the clearance between the ramp and
inside surface of the roller arm.
If the bearing appears worn, roller arm and
ramp clearance can be visually inspected by
looking into the clutch, or the clutch can be
removed from the crankshaft and measured. To
check bearing wear, use either of the following
procedures:
•
Visual Inspection Procedure
1. While rotating the drive clutch clackwise
and counterclockwise, inspect the inside
surfaces of the roller arm; there must not
be any contact between the roller arm and
ramp.

2. If there is no contact between the roller arm
and ramp, the maximum allowable drive-
clutch bearing wear is within tolerance.
The drive clutch i·s acceptable.
3. If there is contact between the roller arm
an9 ramp, the drive-clutch bearing wear is
not within tolerance and the drive clutch
movable sheave and housing must be
replaced.
Measurement Method Procedure
1. Remove the drive clutch from the
crankshaft.
2. Remove housing (cover) and spring.
