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
stationary shaft. If the bar does not clear the inside
edge or is more than 1.5 mm (0.060 in.) from the
inside edge, the offset must be corrected.

CORRECTING OFFSET
1. To correct offset, the driven pulley must be moved
laterally on the driven shaft. Remove the cap
screw and washers securing the driven pulley; then
remove the driven pulley.
„ NOTE: If the driven pulley is tight on the driven
shaft, pull the driven pulley off using the Driven
Pulley Puller (p/n 0744-023).
2. To move the driven pulley inward on the shaft,
remove washer(s) as required from behind the
pulley.
3. To move the driven pulley outward on the shaft,
add alignment washer(s) as required behind the
driven pulley.
„ NOTE: Make sure the keyways match when
installing the driven pulley. Arrange washers to
allow the least amount of “float” on the driven
shaft. A maximum of 1.5 mm (0.060 in.) of float is
acceptable.
4. Install the driven pulley and secure with a cap
screw and washers. Tighten the cap screw to 2.6-
3.3 kg-m (19-24 ft-lb).
CHECKING PARALLELISM
1. Check parallelism of the drive clutch/driven pulley
using the alignment bar and reference points X and
Y with the alignment bar against the driven pulley
at points A and B. Using a calipers or a machinist's
scale, measure X and Y from the back side of the
alignment bar. Measurements X and Y must be
equal or measurement Y must be more than
measurement X, but Y must not exceed
measurement X by more than 1.6 mm (0.062 in.).

„ NOTE: The offset must be correct before check-
ing parallelism.
2. If parallelism is not within specifications, the
parallelism must be corrected.
CORRECTING PARALLELISM
1. To correct parallelism, minor adjustments can be
made by adjusting the torque bumper on the left-
rear engine mount.
A. Loosen the cap screws and nuts securing the
engine mounting brackets to the front end.
B. Using the jam nuts on the torque bumper, adjust
parallelism and periodically check the parallel-
ism. When the parallelism is correct, tighten the
cap screws and nuts securing the engine mount-
ing brackets to the front end; then tighten the
torque bumper jam nuts allowing 1.5 mm
(0.060 in.) clearance between the torque
bumper and the engine.
