TYPICAL
1. Contact
ALIGNMENT BAR IN PULLEYS
NOTE: Prior to performing pulley adjustment, loos-
en torque rod and lock nut as mentioned above in
the GENERAL PROCEDURE subsection.
Pulley Distance Adjustment Method
Pulley distance adjustment cannot be done on REV
series models.
Pulley Alignment Method
Remove pulley and add or remove spacer(s) as re-
quired to obtain the specified alignment.
1. Spacers
NOTE: After alignment hand tighten torque rod so
it slightly contacts engine crankcase. Do not over
tighten, it will disalign pulleys.
DRIVE BELTS
The drive belt is the critical link in transmitting pow-
er from one clutch to the other. The changes in belt
technology and materials have allowed us to take
for granted the kind of reliability and efficiency that
not many years ago we all only dreamed about.
One of the more important changes in drive belts
has been the introduction of Kevlar
®
Fiber B to re-
place fiberglass or polyester cord in the tensile lay-
er of modern drive belts. This material is much
stronger, more flexible, and allows a better adhe-
sive bond with the various rubber compounds used
to build a drive belt.
Another important change in drive belts is the in-
crease in width. The extra width allows us to add
more Kevlar cords in the tensile layer for strength
with today’s high output sleds.
Use only the specific Bombardier drive belt listed
for your application. The drive belt is a calibrated
part of the transmission system. Different belts
with different compounds or angles will change
how your transmission shifts.
Drive belts can vary
±
6 mm (1/4 in) length from
belt to belt. Because of this manufacturing toler-
ance, we recommend measuring your drive belts
and marking their length on the outer cover. Try to
use only belts that are the same length while rac-
ing to keep your clutch set up as consistent as
possible.
