Rivera Primo Brute II Extreme - Manual (Page 2)

FREE PLAY: This term describes the amount of up and down movement in the belt taken at the center-top with a cold drive train. Both
pulleys must be securely tightened ready to run. The correct way to measure free play is to grasp the belt top-center and push up and
down using about 10 pounds of force. The correct free play for enclosed installations is approximately 1/2”-3/4”. Free play is
critical. Both the pulleys and the primary cover expand under the influence of heat during normal operation. If you believe that a
free play problem exists, do not start the motorcycle ! Call first.
VENTING: Primo recommends that enclosed belt installations be vented to allow cool air to circulate into and out of the primary case.
This will keep heat expansion to a minimum & extend belt life. Special Note: 1969 Motorcycles require a #16657 motor seal.
LIMITED WARRANTY:
All pulleys are warranted to be free from defects in material and workmanship under normal use for a period of one year from actual date of purchase.
Seller’s liability shall be limited to repair or replacement of any materials found to be defective, free of charge at it’s plant or authorized service depots,
of specific manufactures components. It is further warranted that products that were designed for a specific purpose, shall perform for that purpose
when installed exactly as defined in the Installation Instructions accompanying the unit. In no event shall Rivera Primo Inc. or seller be liable for con-
sequential or special damages asserted to be attributed to malfunction of our product, for any reason including, but not limited to, damage asserted to

This warranty shall not apply to any products which have been subjected to abuse, neglect or accident, nor shall it apply to any product which has
been repaired or modified by any person not specifically authorized in writing by the manufacturer.
THERE IS NO WARRANTY ON BELTS: Due to the differing conditions and circumstances under which all belts are installed and used, Gates Rubber
Company will not warranty any belt for length of service. Regardless of belt type, keeping your system free of debris and other objects is most impor-
tant. Remember too, improper handling of the belt can shorten service life. Do not crimp the belt. Do not twist the belt. Do not pry the belt onto the
application. If you’re shipping or storing, try to eliminate forward and back-bending of the belt.

IMPLIED WARRANTY OF MERCHANTABILITY AND FITNESS EXCEPT THAT THE MATERIAL SOLD HEREUNDER SHALL BE OF SELLER’S

rial in manufacturing processes or in combination with other substances, or otherwise. Except as otherwise provided herein quality shall be in accor-
dance with seller’s specifications. Final determination of the suitability of the material for the use contemplated by buyer is the sole responsibility of
buyer, and seller shall have no responsibility in connection with such suitability.
WARNING: All primary belt drives should never be operated without the proper safety guards in place. Failure to use belt guards such as
outer primary covers will terminate any existing warranty.

OPTIONAL PRO-CLUTCH TM :
Now that you’ve purchased a legendary Primo Belt Drive, why not
mate that bad-boy to the finest clutch assembly sold today, Rivera Primo’s
Pro-Clutch
TM , part number PC-1000-A.
This baby will easily transmit all of your motor’s horsepower to the
transmission without slipping or grabbing ! Better yet, it’ll do that
without sacrificing smooth, easy hand control.
The PC-1000-A model is engineered for early-model Big Twins, 1936-1984,
and upgrades the clutch assembly in two ways. First, by increasing the
friction area by more than 100%. Secondly, by replacing the old, outdated
coil-spring clutch pack with Rivera Primo’s proprietary diaphragm spring
design. Diaphragm spring-operated clutches have proven to be more
durable & more effective than typical coil-spring clutch packs when utilized
in street & high performance applications. Simply stated, they get the job
done !!
The Pro-Clutch TM installs quickly into the existing clutch basket by removing
the OEM hub and caged(loose) bearings, then installing the supplied hub
adapter assembly and new clutch pack consisting of eight(8) steel and
seven(7) Kevlar friction plates.
So, give us a call and get yours on the way. We’re certain you won’t regret
the move !
