General Maintenance
Periodically check the condition and tension of the drive belt, and
always carry a spare belt. For improved drive-away during extremely
cold temperatures, remove the belt and warm it to room temperature.
Reinstall it before starting the snowmobile.
Drive Belt Removal

complete stop. Apply the brake and lock the parking brake.
2. Open the hood, remove the clutch guard retaining pin and open the
clutch guard.
3. Firmly grasp the belt midway
between the clutches and pull
upward and rearward to remove.
