3. Secure the sheaves using the existing cap screw and
washer making sure the washer is cupped toward the
sheave. Tighten to 60 ft-lb; then install the drive belt.

4. Check drive clutch/driven clutch alignment.

Drive Clutch/Driven Clutch

If premature drive belt wear is experienced or if drive
belt turns over, check parallelism/offset. Also, parallel-
ism/offset must be checked whenever either drive clutch
or driven clutch is serviced. To check offset, use appro-
priate Clutch Alignment Bar. To check parallelism, use
Parallelism Bar.
CHECKING OFFSET (ZR 4000 LXR)
1. With the engine off, open the left-side access panel;
then remove the drive belt.
2. Install appropriate 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 clutch station-
ary 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
clutch 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 stationary
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 (ZR 4000 LXR)
1. To correct offset, the driven clutch must be moved
laterally on the input shaft. Remove the cap screw
and washers securing the driven clutch.
 NOTE: If the driven clutch is tight on the shaft, pull
the driven clutch off using the Driven Clutch Puller.
2. To move the driven clutch inward on the shaft,
remove alignment washers located on driven shaft
from the chain case of the clutch.
3. To move the driven clutch outward on the shaft, add
alignment washers to the driven shaft on the chain
case of the clutch.
4. Arrange washers to obtain correct offset; then install
driven clutch, cap screw, and washers.
5. Install the drive belt.
CHECKING OFFSET (6000/8000)
 NOTE: The drive belt does not need to be removed
to check offset.
1. Set the brake lever lock; then remove the left-side
access panel.
2. Place Alignment Plug into the bore of the drive
clutch; then place Alignment Bar onto the stationary
sheave of the driven clutch and into the groove of the
alignment plug.
SNO-578
NOTE: Make sure the alignment bar is positioned

over the driven clutch cap screw.
3. If the offset is correct, the line on the alignment bar
will be aligned with the outside of the alignment
plug. If not, proceed to Adjusting Offset.
