MAINTENANCE AND LUBRICATION
PVT System
Low Range Use May Reduce PVT
Operating Temperatures
The basic operation of the Polaris PVT system is dependent on engine
speed and vehicle torque requirements. As engine speed increases, the
force exerted on the movable drive sheave by the flyweights also
increases. This, in turn, increases the amount of “pinch” applied to the
drive belt. Similarly, if the engine speed decreases, the amount of
centrifugal force decreases, reducing the amount of belt “pinch.”
The PVT system rotates at high speeds, creating large amounts
of force on clutch components. Extensive engineering and
testing has been conducted to insure the safety of this product.
However, as the owner you have the following responsibilities to
make sure this system remains safe:
S Do not modify any component of the PVT system. Doing so
may reduce its strength so that a failure may occur at high
speeds. This system has been precision balanced. Any
modification will cause the system to be out of balance,
creating vibration and additional loads on components.
S Routine maintenance is the responsibility of the owner. Al-
ways follow recommended maintenance procedures. See
your dealer!
S This PVT system is intended for use on Polaris products
only.
S The PVT housing must be securely in place during opera-
tion.
Failure to comply with this warning can result in severe injury or
death.
