Removing Drive Belt (ACT
Roller Driven Pulley)
NOTE: Changing a drive belt
can be done by the snowmobile
owner if qualified to do so. If the
owner does not feel qualified,
take the snowmobile to an autho-
r i z e d A rc t i c C a t S n ow m o b i l e
dealer for this service. This ser-
v i c e i s a t t h e d i s c r e t i o n a n d
e x p e n s e o f t h e s n o w m o b i l e
owner.
NOTE: On M-Series models, the
drive belt can be removed and
installed by removing the side
panel and pushing in on the
driven torque bracket (cam) to
separate the sheaves.
1. Turn ignition key to the OFF
position and wait for all moving
parts to stop.
2. Set the brake lever lock.
3. Open the hood; then open the
belt guard.
4. Remove the driven pulley plug
from the belly pan.
5. Using the spark plug wrench,
screwdriver, and Belt Deflec-
tion Tool (p/n 0644-435) from
the tool kit, remove the sheave
adjuster from the end of the
driven pulley. Account for and
remove the O-ring and shim
washers. Note the orientation of
the components for installing
purposes.

6. With the O-ring and shim wash-
ers removed, carefully thread
the sheave adjuster back into
the driven pulley; then tighten
the adjuster with the deflection
tool/screwdriver/spark plug
wrench assembly until it bot-
toms against the driven shaft.
NOTE: By bottoming the sheave
adjuster against the driven shaft,
the sheaves of the driven pulley
will spread far enough to allow
the removal of the drive belt.
7. Remove the drive belt from the
drive clutch and driven pulley.
