8) Install bottom disc, floater, top disc and alignment tool to properly align the discs. Install pressure
ring (shim packages if removed), pressure plate assembly, flat washers and nuts. With the nuts just
installed onto studs rotate the alignment tool to be certain the discs are aligned. Do not use thread
adhesive (LocTite) on the studs or nuts!
9) Strap Drive models only: Install bottom disc, floater with straps onto stud in flywheel, top disc,
pressure ring, (shim packages if removed) and pressure plate assembly. Both drive straps must be
offset and not on top of each other. The drive straps must be offset!! Do not use thread adhesive
(LocTite) on the studs or nuts! Tighten the strap nuts to 25 ft lbs. See Figure 6.
Figure 6 Figure 7
10) Pressure Plate tightening sequence is critical at this point. Tighten pressure plate nuts to 25
ft/lbs in a star pattern (1 o’clock, 7, 3, 9, 5, 11). Place a straight edge onto the pressure plate across
the fingers. When the nuts are properly tightened, the fingers will just contact the straight edge.
Final torque is determined when the diaphragm fingers are even with the straight edge. This
should be close to 35 ft/lbs…again tightening in the star pattern. See Figure 7.
11) Check diaphragm finger height at this time by placing a straight edge onto the pressure plate
across the finger opening. All of the fingers should be at the rear surface of the pressure plate.
12) Continue with the bell-housing, throw-out bearing and transmission installation.
13) Break-in period…Do not break-in this clutch system on a chassis dyno!!
14) Traction Control devices must be off!
15) Clutch adjustment is accomplished by removing shims as the discs wear. Each shim measures
.XXY” thick. Remove the same amount of shims from each stud when making adjustments!
Remember from Step 10 the adjustment is correct when the pressure plate nuts are tight and the
diaphragm fingers are even with the rear face of the pressure plate.
