Rivera Primo Brute III Extreme 2007 Touring Enclosed Belt Drive - Manual (Page 2)

NOTE: In some cases it may be neccesary to remove material from
the inner primary to clearance for the belt. The belt must never come
in contact with the inner primary surface.
This outer primary
has been relieved in
the areas indicated
by arrows to allow for
adequate belt clear-
ance. Most installa-
tions require some
grinding on the inner
and outer primarys.
Now remove front &
rear pulleys for final
installation.
Install front pulley (without front
inside guide) & rear pulley with-
out the belt & check alignment as
shown(straight edge flush with
starter ring gear lines-up with
inner edge of front pulley) remove
pulleys and proceed with installa-
tion. If alignment isn’t satisfactory
use shims to space only the front
pulley. The rear pulley will NEVER
have shims behind it.
After ensuring proper pul-
ley alignment, again check
the areas indicated in the
photo for belt and/or pul-
ley clearance. Rear pulley
and belt clearance should
be checked before operat-
ing the motorcycle.

Shims are manufactured from high qual-
ity steel, precision ground for parallel &
flat surfaces to ensure perfect pulley
alignment. Correct pulley alignment &
correct belt tracking are a must for long
belt life. These shims make pulley align-
ment easy. Shims are available in .025",
.050", .070", & .100” thick dimensions, or
a kit of one-of-each size (1101-0500).
