4 STEP 4:
Install the Motor Plate (front section PP-403-P or PP-503-P),
Start the four front section bolts, but only hand tighten at this
time!
Install the 4 center bolts that attach the front section of the
Motor Plate Assembly to the rear section. TIGHTEN THE
MOTOR PLATE BOLTS, THE BEARING SUPPORT BOLTS &
THE CENTER BOLTS TO 29 FOOT POUNDS TORQUE, while
ensuring that the plates are properly seated and aligned. If you
have a PP-400 (show chromed alternator rotor chrome alter-
nator cover) install it now!
STEP 5:
Apply a liberal amount of Rivera Primo Inc. special bearing
grease (included in the kit) to the transmission main-shaft
splines to act as a corrosion inhibitor. The grease also protects
the splines by absorbing shock-loads & preventing rust.
STEP 6:
Install the starter coupler mechanism (coupler, extender,
spring, pinion gear, thrust washer, lock washer, and bolt).
Make sure the lock washer is correctly oriented. Use 1-2
drops of blue threadlock & snug the bolt. Bend the locking-
tab over to keep the bolt from vibrating loose.

STEP 7:
Install the rear pulley (clutch basket) and hand tighten the clutch hub nut making sure it is snug. Note that this
nut is left-hand thread. At this time it is important to check the air gap between the back side of the starter ring
gear and the pinion gear. Recommended gap should be .075” to .125”. Use an 1/8” Allen wrench to measure the gap.
Just slip the short end of the wrench between the ring gear & the pinion gear. If it fits, great. If there is too much gap,
the jackshaft assembly should be shimmed to reduce the gap to the spec above (order #1185-0500 shim kit).
