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 or other qualified service person 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 clutch air 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.

To replace the belt, do the following:
  1. Position the vehicle on a level surface. Block the wheels to prevent vehicle movement. Place the transmission in neutral.
  2. Lift the cargo box.
  3. Remove the clutch cover using a 3/8” socket with ratcheting wrench and extension.
  4. Pull the bottom of the cover outward and over the suspension to remove it.
  5. Make sure the cover gasket does not fall out of the groove when removing the cover.
  6. Squeeze the belt together so that it submarines further into the driven clutch, creating slack in the belt between the clutches.
  7. Remove the belt by using the slack to pull part of the belt off the driven clutch.
  8. Rotate the driven clutch by hand until the belt is completely off.
  9. Slide the front of the belt out from between the drive clutch and inner clutch cover to completely remove it.
  10. Remove all debris wrapped in and around the PVT system.
  11. Remove all debris from the entire clutch air duct passage.
  12. Check for signs of damage to seals on the transmission and engine. If any seals appear to be damaged, your vehicle requires prompt service. Your POLARIS dealer can assist.
    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.).
  13. To install a belt, place one end of the belt over the driving clutch. Route the belt over the top of the driven clutch and down into the groove of the clutch to allow slack in the belt. Rotate the driven clutch by hand until the belt falls into place.
  14. Reinstall the clutch cover in the reverse order of removal, fitting the top of the cover into place, then working the bottom of the cover over the suspension.
  15. Install all clutch cover screws. Torque to 4-5 ft. lbs. (5.5-6.5 Nm).

POLARIS Variable Transmission (PVT) System PVT Drying

Image
There may be some instances when water is ingested into the PVT system. Use the following instructions to dry it out before operating:
  1. Position the vehicle on a level surface.
  2. Remove the red drain plug on the outer clutch cover. Allow the water to drain completely. Reinstall the drain plug.
  3. Place the transmission in PARK.
  4. Start the engine.
  5. Apply varying throttle for 10-15 seconds to expel the moisture and air-dry the belt and clutches. Do not hold the throttle wide open for more than five (5) seconds.
  6. Allow the engine RPM to settle to idle speed. Apply the brakes. Shift the transmission to the lowest available range.
  7. Test for belt slippage. If the belt slips, repeat the process.
  8. Your vehicle requires service as soon as possible. Your POLARIS dealer can assist.
