NOTE: Replace the OEM hex-head bolt (Dyna Glide only) with the
button-head Allen bolt provided in the kit. TORQUE THE BUTTON-
H
EAD BOLT TO 29 FOOT POUNDS.
Early FXR models may need to have some material removed from
the inner primary in the area indicated by the X’s. Check
pulley/belt clearance here before tightening clutch hub nut.
This inner primary (Early
Evo) has had a tab
removed to allow belt
clearance in the area indi-
cated. Most installations
require some grinding on
the outer primary webbing.
Install front pulley. Install the
rear pulley without the belt &
check alignment as shown
(straight edge flush with rear of
ring-gear lines-up with outer
edge of front pulley). Remove
pulleys and proceed with instal-
lation. If alignment isn’t satisfac-
tory see photo 8. The provided
.100” washer can be used to
space the front pulley outward
as needed, however it may be
nesecary to use less or more
shim.
After ensuring proper pul-
ley alignment, again
check the areas indicated
in the photo for belt and/or
pulley clearance. Always
check rear-pulley and belt
clearance here before
operating the motorcycle.

Shims are manufactured from high quality 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 .020", .030", .050", .075" &
.100” thick dimensions, or sets of "one-of-each.”
