STEP 13
Coat the threads of the transmission
mainshaft with 3 drops of Blue threadlock.
Start the supplied clutch hub nut on the
shaft & hand tighten (remember this is a
left-handed thread application). Finish this
procedure with your impact wrench.
Torque the clutch hub nut to factory
specs, 70-90 foot pounds of torque. The
belt should have no more than 1” total up
and down free play and no less than 1/4”
at the center of the belt.
STEP 14
Coat the threads of the Pro-Clutch studs
with Anti-Seize compound. This will pre-
vent the shouldered nuts from sticking to
the clutch hub stud threads during disas-
sembly. Install the clutch adjusting screw
into the press¬ure plate. Insert the pres-
sure plate (with the stamped “OUT” fac-
ing out) into the rear pulley, up against
the last steel plate previously installed in
STEP 8.
STEP 15
Prepare the diaphragm spring, the spring
retainer, lock tabs and shouldered nuts
for installation. Remember, the beveled
side of the spring retainer faces in. In ad-
dition, the retainer has a stamped “OUT”
marking on it. This side should face out.
STEP 16
Install the diaphragm spring, making
sure the notches register correctly with
the now-in-place pressure plate.
Follow this with the spring retainer
(beveled side facing in), now assembled
with the locking tabs and the shouldered
nuts.
