Rivera Primo Primo Brute II Classic - Manual (Page 3)

Again, belt free-play should be approximately 3/4” - to- 1” with a cold drive train (not operated for 24 hours). Check belt
up & down play as pictured. If you cannot achieve adequate belt play, call Primo Belt Drives for advice.
For 11mm belt drive installations (Brute II Classic) free play should
be adjusted via the idler to 3/4” - to - 1” with a cold drive train (not
operated for 24 hours). The idler plate mates with the OEM serrated
plate. Use Rivera Red thread lock on the idler bolt threads & adjust
the idler to give the aforementioned belt play, and tighten in position.
Do not operate the motorcycle with a belt that is too tight, you may
damage drive train components. Aluminum pulleys expand under the
influence of heat. Check your belt tension with the drive train at nor-
mal operating temperature (15-20 minute riding at 55 MPH. The belt
should be snug but not “bowstring” tight.
Install the clutch pack exactly the way it was removed from the bas-
ket. Steel plate first, then fiber, alternating until all the plates are
installed. Put a dab of high-quality anti-seize on the clutch hub studs
as pictured.
Install the pressure plate as shown with the adjuster screw backed
out most of it’s thread length.
