DRIVE BELT / CLUTCH MAINTENANCE
DRIVE BELT REMOVAL
IMPORTANT
Do not attempt to remove the drive belt after operating
in reverse. The snowmobile must be stopped after
forward motion to prevent damage to components
during belt removal. Rotate the driven clutch
counterclockwise 1/4 turn by hand to ensure forward
engagement before attempting to remove the belt.
1. Stop the engine after operating in a forward motion.
2. Turn the ignition key off. Wait for the engine to come
to a complete stop.
3. Rotate the driven clutch counter-clockwise 1/4 turn by
hand to ensure forward engagement.
4. Lock the parking brake.
5. Remove the left side panel.
6. Retrieve the L-wrench
q
. Install the wrench into the
open threaded hole in the outer sheave of the clutch.
7. Turn the wrench clockwise until the sheaves open far
enough to remove the belt.
8. Firmly grasp the belt
w
midway between the clutches
and pull upward and rearward to remove it from the
driven and then drive clutch.
NOTICE
The fender/console can be spread apart as needed to
access the driven clutch.
DRIVE BELT INSTALLATION
NOTICE
Always clean the drive belt using a mixture of warm,
soapy water. Allow to air dry. When installing the belt,
verify POLARIS or the part number can be read from
the outside of the snowmobile.
1. Verify the driven clutch sheaves are open. If they are
not, install the L-wrench and open the sheaves.
2. Drop the drive belt over the drive clutch and pull back
the slack. The belt cord line should be flush with, or
slightly above, the outer circumference of the driven
clutch sheaves.
3. Hold the belt down between the sheaves and roll the
bottom portion over the outer clutch sheave. Work the
belt to the outer edge of the sheave.
