INSTALLATION
1. Resurface or replace flywheel. Surface must be smooth or premature clutch failure can occur. REMEMBER:
Machining the flywheel past the recommended .060" moves the pressure plate away from the transmission. In
this event, install a fiber spacer (provided) on the input shaft between the clutch brake and the transmission. The
release yoke in the bell housing may not align properly with the pressure plate release bearing housing. Linkage
adjustment may be required during clutch set-up. If resurfacing is required, while the flywheel is mounted to the
crank shaft, verify correct flywheel dimensions as seen in Figure 2 and Figure 3.
2. Inspect and dial-indicate the mating surface of engine flywheel housing and clutch bell housing for alignment.
Check flywheel run out. CAUTION: If misalignment is greater than the recommended limits, this will cause poor
clutch release, rapid wear on transmission input shaft and destruction of the clutch disc. Excessive flywheel run
out may cause severe vibration in vehicle driveline.
3. A new pilot bearing with a VITON
of movement on transmission input shaft.
4. Verify disc fits in flywheel bore (Figure 1). Slide disc the length of the input shaft checking for twist and wear. Insert
alignment shaft through bearing housing. Install rear disc (oriented correctly), center plate, and front disc (oriented
correctly) on alignment shaft. Move clutch housing towards flywheel making sure cover fits into flywheel pilot.
5. Install the bolts (7/16 x 14unc x 2-1/4) that fasten the clutch housing on the flywheel. Tighten the bolts to the
specified torque and the sequence specified by the manufacturer of the vehicle or transmission (Recommended
40-50 ft-lbs). Bolts should be Grade 5 or greater.
6. Remove caging fork from under the release bearing. Remove alignment shaft. Verify bearing distance from cover
is 1/2" - 5/8" (See Figure 4). NOTE: Anytime the clutch is removed from the flywheel, the caging fork needs
to be reinstalled. Failure to do so will cause adjusting arm to fall out of retainer stud. See Figure 8 in Reset
Procedure.
