The drive belt represents one of the most critical performance links in your Polaris vehicle—the link between the engine and high performance. The drive belt, also known as a CVT belt (continuously variable transmission belt), is a key component of ATV, UTV and SxS transmission systems. They are developed and tested on all our engines for all environments and conditions. Our belts are designed, engineered and tested by Polaris Engineers and field test crews to ensure they deliver a perfect fit, high performance and excellent durability. Nothing else comes close. WHY REPLACE YOUR BELT? An old or damaged belt may damage other components in the clutch box, and a worn belt will cause jerky drive-away, false misfire and accelerated wear of clutch bushings. When to Replace Your Belt If you find cracks, loose cords, or missing cogs, if drive-away and engagement has gotten “jerky”, or any “hour-glassing” where a section has worn narrower, it’s time for a new belt. How to break in your belt Inspect and clean debris from the clutch covers, ducting and engine compartment. Remove any rubber residue from sheaves by scuffing with a pad. Clean sheaves with evaporating degreasing solvent like rubbing alcohol, or brake cleaner. Finish by driving in low gear and avoid high RPMs for first 5 miles (8 km) MINIMUM of operation.
