Rivera Primo Brute IV Extreme for 1990-05 Dyna Models - Manual (Page 2)

STEP 1
Begin by disconnecting the battery cables. Remove all of the OEM primary drive components includ-
ing the inner primary cover, as well as the factory inner bearing race on the trans mainshaft. Check
for leaky seals. Check & tighten, if necessary, the shift lever. Should you wish to change the gearing,
now’s the time to install Primo’s billet aluminum rear drive pul¬ley. This pulley weighs 3 lbs. less than
the stock one. It’s available in 29, 30, 32 & 34-tooth sizes.
STEP 2
Take the front motor plate spacer (engine case to
motor plate) and place it over the alternator and up
against the engine case. Do not secure with bolts at
this time. Make certain that all holes are properly in-
dexed so that the spacer is properly aligned.
STEP 3
Apply a coating of Anti-Seize compound on the
transmission mainshaft to the area where the motor
plate bearing will come to rest. Make certain you do
this prior to installing the motor plate section.

fittings (not supplied) on the rear of the
motorplate and the oil filter nipple on
the front middle of the motorplate (sup-
plied) only if you will be using a spin-on
center mount filter with this install).
