Snowmobile Belt Installation Tips

The belt on your snowmobile is an integral part of the drive system and can dramatically affect how the snowmobile performs and feels. By following the recommendations below you will achieve maximum performance and extend the life of the Ultimax XS belt.
  1. Be sure you have the correct part number for your application.

  2. Resist back-bending the belt as this produces undo stresses and will shorten belt life.

  3. Proper clutch alignment is critical.

  4. Install the belt making sure it sits within the sheaves correctly. Start by adjusting the secondary (driven) clutch so the cord line of the belt is flush with the outside circumference of the secondary. The XS belt may look like its riding high because of the large top cogs. Be sure to look at the cord line not the top of the belt.

  5. Apply the brake and start the engine. Belt noise may be a sign of excessive belt tension caused by improper belt installation and further adjustment may be required. Belt tension can be reduced by lowering the belt in the secondary following the manufacturer’s instructions.

  6. For improved performance every new belt needs to be seated to the clutch faces. To accomplish this, run the snowmobile for the first 30 miles at half throttle or less.

  7. If for any reason the belt is removed from the snowmobile, it should be reinstalled in the same direction. An easy way to remember this is to always put the belt on so you can read the label on the belt.

  8. Carlisle doe not recommend the use of belt dressings.

  9. The engine should be at normal operating temperature before riding to allow the belt to warm up.

  10. Belt damage could occur if the snowmobile track is frozen to the ground and the belt is engaged. Break the track free before riding.
Following these simple steps will allow you to spend more time on the trails and less time in the shop.
