How to Replace a Snowmobile Drive Belt

The secondary clutch of a snowmobile drive system serves as a method to properly balance the correct gear ratio for the load. It uses a ramp and springs to move the drive belt from the center of the clutch to the outer rim. A worn-out belt can significantly reduce the power and performance of the sled. The drive belt should be changed every 1,200 to 1,500 miles. Changing the drive belt on a snowmobile is easy following some simple steps.

      Grab the inside sheave of the secondary clutch with your left hand. Rotate the sheave counterclockwise while pushing the clutch open. This will release the tension on the belt. Pull the belt out and away from the secondary clutch and remove it from the primary clutch assembly.

      Line up the new belt so you can read the writing on the outside of the belt. Place the belt around the primary clutch. Push the belt over the sheave on the secondary clutch, starting at the top and working clockwise until the belt is pushed into place.
