Pvt System - Polaris ATV 2001 Owner's Manual

PVT SYSTEM OPERATION

PVT System

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.
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."
