Rivera Primo Brute IV Extreme - Manual (Page 2)

The photo to the left shows the basic component pieces as
delivered in the BRUTE IV EXTREME belt drive kit. Keep
in mind that this photo shows both pulleys with their stain-
less steel flanges already mounted on them. In addition,
the entire Pro-Clutch pack and all of its components have
been pre-assembled for purposes of illustration.
STEP 1
Begin by disconnecting the battery cables. Remove
all of the OEM primary drive components including
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.
STEP 4
Assemble the 4 stand-offs to the motor plate (may
be factory-assembled). These pieces will act as the
support for the outer guard. Begin by thread¬ing in
each stud into each stand-off using 3 drops of Red
loctite.Thread them into the stand-offs until they bot-
tom (should be left with 3/4” exposed). Now thread
each stand-off into each of the locat¬ing points on
the motor plate. Tighten until they bottom-out on the
plate.
2
At this time install the center-shift plug with three
drops of blue thread locker (or the center shift
support if you are using RPI billet mid-controls). In-
stall oil line nipples (not supplied) on the rear of the
motorplate if the center mount oil filter will be used.
