CAUTION
Do not apply Loctite to the cap screw or damage to the
gear case will occur.
3. Check drive clutch/driven pulley alignment.
4. Install the drive belt.
NOTE: For installing drive belt, see Drive Belt in
this section.
Drive Clutch/
Driven Pulley
If premature drive belt wear is experienced or if the
drive belt turns over, parallelism/offset must be
checked. Also, parallelism/offset must be checked
whenever either the drive clutch or driven pulley is
serviced. To check offset, use appropriate Clutch
Alignment Bar. To check parallelism, use Parallelism
Bar.
CHECKING OFFSET
1. Open the left-side access panel; then remove the
belt guard.
2. Install Clutch Alignment Bar between the drive
clutch sheaves.
3. Allow the bar to rest on the drive clutch shaft and
against the outside edge of the driven pulley sta-
tionary sheave.
NOTE: The alignment bar must extend beyond
the front edge of the drive clutch.
4. With the bar against the outside edge of the driven
pulley stationary sheave at points A and B, the bar
should just clear the inside edge of the stationary
sheave of the drive clutch and rest on the station-
ary shaft at point C. If the bar either will not clear
the inside edge or is more than the specified
amount, the offset must be corrected.

CORRECTING OFFSET
1. To correct offset, the driven pulley must be moved
laterally on the input shaft. Remove the cap screw
and washers securing the driven pulley.
NOTE: If the driven pulley is tight on the shaft,
pull the driven pulley off using the Driven Pulley
Puller.
2. To move the driven pulley inward on the shaft,
remove alignment washer(s) from the gear case
side of the pulley.
3. To move the driven pulley outward on the shaft,
install additional alignment washer(s) on the gear
case side of the pulley.
4. Arrange washers to obtain correct offset; then
install driven pulley, cap screw, and washers and
tighten to 32 ft-lb.
CAUTION
Do not apply Loctite to the cap screw or damage to the
gear case will occur.
CAUTION
Do not allow the driven pulley to "float" on the input
shaft. Damage to the driven pulley will occur.
CHECKING PARALLELISM
(800/1000/1100 cc)
1. Remove the drive belt; then open the driven
sheaves and place Clutch Alignment Bar (Parallel-
ism) between the sheaves. Release the sheaves.
2. Check the parallelism of the drive clutch/driven
pulley using the parallelism bar and reference
points X and Y with the parallelism bar between
the driven sheaves. Using a caliper or a machin-
ist's scale, measure X and Y from the back side of
the parallelism bar to the back side of the drive
clutch sheave. Measurement Y must be 0.060 in. ±
0.020 in. more than measurement X, but Y must
not exceed measurement X by more than 0.100 in.
