STEP 11
After insuring correct alignment, remove the front and rear pulley. Re-Install the front pulley, rear pulley and belt at the
same time. Place the washer on the sprocket shaft, then hand thread the front pulley nut onto the shaft torqueing it to 150-
165 Ft. Lbs. Next apply 3 drops of blue thread locker, then hand thread the left hand nut onto the transmission mainshaft
and torque to 80-90 Ft. LBS. We recommend using a pnuematic impact driver to torque the front pulley nut.
STEP 10
At this point it’s time to address the starter jackshaft components which are included with the belt
drive kit (see last page for an exploded view of the starter mechanism).
Begin by installing the starter coupler onto the end of the starter motor. Then the remaining pieces . . .
the extender, spring, pinion gear, thrust washer, lockwasher and bolt. Insert this assembly into the
coupler. Make certain the lockwasher is correctly oriented to the slot in the extender. Tighten the bolt.
Bend the locking tab over to keep the bolt from vibrating loose.
STEP 9
Install the front pulley, rear pulley without the belt. Place the washer on
the sprocket shaft, then thread the front pulley nut onto the shaft torque-
ing it to 150-165 Ft. Lbs. Next torque the transmission mainshaft nut 80-
90 Ft. LBs. Now check the alignment between front & rear pulleys and
correct, if necessary, by adding spacing behind the front pulley (Primo
sells these pulley shims in thicknesses of .020”, .030”, .050”, .075” and
.100”) slip the front pulley into the belt and onto the engine shaft. NEVER
space out the rear pulley.
Visually re-check your work to make sure all clearances appear correct
