CHECKING BEAR
IN
G
WEAR
The
c
le
arance between
th
e
hex
shaft
and
bearing
is critical
for
correct
drive clutch operation. The
f lats
on the drive clutch are directly assoc iated
with the large bearing area.
The
maximum allowable bearing wear
is limited
by the clearance between the
ramp
and
ins
id
e sur·
face of the roller arm.
If
the bearing appears worn, roller arm
and
ramp
c learance can
be
visually inspected
by looking
in·
to the clutch, or the clutch
can
be removed
from
the crankshaft and
measured.
To check bearing
wear, use either of the fo
ll
owing procedures:
Visual Inspection Procedure
1.
Wh ile
rotat
ing t
he
drive clutch clockwise and
counterclockw ise,
inspect the inside
sur-
faces of the roller arm;
there
must
not
be any
contact between the
roller
arm and
ramp.

2.
If there
is
no
contact between
t
he rolle
r
arm
and ramp, the maximum allowable drive-
clutch bearing wear
is
within
tolerance.
The
drive clutch is acceptable.
3.
If there is contact between
the roller
arm and
ramp, the drive-clutch bear ing wear is
not
within tolerance and the drive clutch movable
sheave
and housing bearings must be replac-
ed.
Measurement
Method Procedure
1.
Remove
the drive clutch
from
the crankshaft.
2.
Remove housing
