MAINTENANCE
POLARIS Variable Transmission (PVT) System
WARNING
Failure to comply with the instructions in this warning can result in severe injury or death.
Do not modify any component of the PVT system. Doing so may reduce its strength so that a failure
may occur at a high speed. The PVT system has been precision balanced. Any modification will cause
the system to be out of balance, creating vibration and additional loads on components.
The PVT system rotates at high speeds, creating large amounts of force on clutch components. As the
owner, you have the following responsibilities for your own safety and the safety of others:
• Always follow all recommended maintenance procedures. Always look for and remove debris inside
and around the clutch and vent system when replacing the belt.
• See your dealer as outlined in the owner's manual.
• This PVT system is intended for use on POLARIS products only. Do not install it in any other product.
• Always make sure the PVT housing is securely in place during operation.
Belt Replacement/Debris Removal
If a belt fails, always clean any debris from the duct and from the clutch and engine
compartments when replacing the belt.
WARNING! Failure to remove ALL debris when replacing the belt could result in vehicle damage, loss
of control and severe injury or death.
1. Remove the seat and the underseat storage box.
2. Remove the clutch cover screws and open the clutch cover. Remove all debris wrapped
in and around the PVT system.
3. Remove all debris from the entire clutch air duct passage.
4. Check for signs of damage to seals on the transmission and engine. See your dealer
promptly for service if any seals appear to be damaged.
Tip: Belt slip is responsible for creating excessive heat that destroys belts, wears clutch components
and causes outer clutch covers to fail. Switch to low range while operating at slower speeds to
extend the life of the PVT components (belt, cover, etc.).
