OPERATION
Polaris Variable Transmission
Preventing Belt Slip / Failure
Belt slip creates heat that destroys belts and causes outer clutch covers
to fail. Avoid heavy pulling and extended low speed operation.
WARNING
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. Extensive engineering and
testing has been conducted to ensure the safety of this product.
However, as the owner, you have the following responsibilities to
make sure this system remains safe:
S
Always follow all recommended maintenance procedures. See
your dealer as outlined in the owner’s manual.
S
This PVT system is intended for use on Polaris products only.
Do not install it in any other product.
S
Always make sure the PVT housing is securely in place during
operation.
PVT Drying
If water is ingested into the PVT system, dry it before operating the
vehicle.
1. Remove the drain plug. Drain the water. Reinstall the drain plug.
2. Place the transmission in neutral. Lock the mechanical parking
brake. Start the engine.
3. 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.
4. Allow the engine RPM to return to idle speed, then shift the
transmission to the lowest available range.
5. Test for belt slippage. If the belt slips, repeat the process.
6. Take the vehicle to your dealer for service promptly.
