STEP 1:
Begin by removing all the OEM primary-drive components
including the inner primary cover, AND THE FACTORY INNER-
BEARING RACE ON THE TRANSMISSION MAIN SHAFT! Check
the motor shaft & transmission main shaft for leaky seals.
Check & thoroughly clean the motor drive shaft & trans main
shaft. Check & tighten the shift-lever as needed at this time!
If you wish to change the
final drive ratio, now is the
time to install a rear belt
drive transmission pulley
(tighten nut per procedure
outlined in HD factory ser-
vice manual). Primo’s billet
aluminum rear drive pulley is available with 29, 30, 32, or 34
teeth & weighs 3 pounds less than the OEM unit.
STEP 2:
Install the starter extender onto the end of the starter
motor as shown. This component must be installed prior
to the installation of the bearing support.
STEP 3:
Install the bearing support (rear motor plate section PP-404-P
or PP-504-P) or install the one piece motor plate (PP-702-P)
at this time. Carefully align the bolt-holes and install the bear-
ing support over the starter extender. Only hand tighten the
bolts at this time. Attach the 1990 or later starter motor to the
rear of the bearing support.
STEPS 3A & 3B:
Rivera Primo Inc. PP-502 Motor Plate assembly (rear sec-
tion) for Dyna Glide is notched for swing-arm pivot-boss
clearance (photo 3A). Approximately .125” of material
must be removed from the end of the nut & swing arm
pivot bolt assembly (photo 3B) to allow clearance for the
Brute IV
TM starter ring-gear before installing the clutch bas-
ket. Remove enough material from the end of the nut &
bolt to allow the starter ring gear & clutch basket assembly
to be installed & rotated with approximately .100” clear-
ance between the ring gear & the nut-bolt assembly.
