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

. 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

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.
