3. Install the pulley assembly by using the SST, then
install the cover and the snap ring.
76G16X-614
4. Install the drive plate onto the drive shaft together
with the original shim(s).
5. Using the SST (49 9201 010) to prevent the drive
plate rotation, tighten the bolt. (Refer to page
16-14.)
Tightening torque: 14—16 N-m
(1.4—1.6 m-kg, 10.1—11.5 ft-lb)
76G16X-009
6. Check that clutch clearance is between 0.3—0.6
mm (0.01—0.02 in). Adjust clearance by using
shim(s), if necessary. Adjusting shims are availa-
ble in the following thicknesses:
0.1 mm (0.0039 in)
0.3 mm (0.0118 in)
0.5 mm (0.0197 in)
Standard clearance:
0.3—0.6 mm (0.01—0.02 in)
