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 recommended in the owner’s manual and on safety labels.
  • 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 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.).

Belt Replacement / Debris Removal

WARNING
Failure to remove ALL debris when replacing the belt could result in vehicle damage, loss of control and severe injury or death.
Use the shock/clutch tool from the tool kit to slightly open the sheaves to aid in debris removal and belt installation.
  1. Insert hooked end of tool.
  2. Apply force to opposite end of tool to spread sheaves.

  1. Allow hot components to cool before performing this procedure.
  2. Remove the clutch cover screws and open the clutch cover. (It does not have to be removed from the vehicle.) Remove all debris wrapped in and around the PVT system.Image
  3. Remove all debris from the entire clutch air duct passage .

  4. 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 or other qualified person 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.)

PVT Drying

There may be some instances when water is accidently ingested into the PVT system. Use the following instructions to dry it out before operating.
NOTICE
When washing the vehicle, always avoid spraying water directly toward the PVT intake duct. See the Washing the Vehicle section for details.
  1. Remove the clutch cover drain plug.
  2. Allow the water to drain. Reinstall the drain plug.
  3. Place the transmission in PARK. Apply the brakes.
  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 10 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 or authorized person can assist.
