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 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.
NOTE
Inspect the entire clutch outlet duct (including the outlet duct screen) when replacing a drive belt. Remove any debris found in the outlet duct or outlet duct screen.
To remove the belt, do the following:
  1. Remove the nine fasteners that retain the outer clutch cover.

Belt Inspection

To inspect the drive belt, do the following:
  1. Inspect belt for hour-glassing (extreme circular wear in at least one spot and on both sides of the belt). Hour glassing occurs when the drive train does not move and the drive clutch engages the belt.
  2. Inspect belt for loose cords, missing cogs, cracks, abrasions, thin spots, or excessive wear. Compare belt measurements with a new drive belt. Replace if necessary.
  3. Belts with thin spots, burn marks, etc., should be replaced to eliminate noise, vibration, or erratic PVT operation.

Belt Installation

NOTE
Be sure to install belt in the same direction as it was removed.
  1. With the clutch spreader tool installed, loop the belt over the drive clutch and over the driven clutch.

  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.
