DRIVE BELT REMOVAL
NOTICE
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 counter-clockwise
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. Lock the parking brake.
4. Remove the left side panel.
5. Rotate the driven clutch counter-clockwise 1/4 turn by hand to ensure
forward engagement.
6. Locate the L-wrench in the tool kit. 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. If the wrench does not turn readily, rotate the driven clutch
counter-clockwise an additional 1/4 turn by hand and try again.
