PVT SYSTEM OPERATION
PVT System
Low Range Use May Reduce PVT
Operating Temperatures
The basic operation of the Polaris PVT system is dependent on en-
gine speed and vehicle torque requirements. As engine speed in-
creases, the force exerted on the movable drive sheave by the fly-
weights also increases. This, in turn, increases the amount of
“pinch” applied to the drive belt. Similarly, if the engine speed de-
creases, 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 engi-
neering and testing has been conducted to insure the safety
of this product. However, as the owner you have the follow-
ing responsibilities to make sure this system remains safe:
D
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.
D Routine maintenance is the responsibility of the own-
er. Always follow recommended maintenance proce-
dures. See your dealer!
D This PVT system is intended for use on Polaris prod-
ucts only.
D The PVT housing must be securely in place during
operation.
Failure to comply with this warning can result in severe injury
or death.
