PVT SYSTEM OVERVIEW
General Operation
The Polaris Variable Transmission (PVT) consists of three
major assemblies:
1) The Drive Clutch
2) The Driven Clutch
3) The Drive Belt
The internal components of the drive clutch and driven clutch
control engagement (initial vehicle movement), clutch upshift
and backshift. During the development of a Polaris ATV, the
PVT system is matched first to the engine power curve; then to
average riding conditions and the vehicle’s intended usage.
Therefore, modifications or variations of components at random
are never recommended. Proper clutch setup and careful
inspection of existing components must be the primary
objective when troubleshooting and tuning.
Drive Clutch Operation
Drive clutches primarily sense engine RPM. The two major
components which control its shifting function are the shift
weights and the coil spring. Whenever engine RPM is
increased, centrifugal force is created, causing the shift
weights to push against rollers on the moveable sheave, which
is held open by coil spring preload. When this force becomes
higher than the preload in the spring, the outer sheave moves
inward and contacts the drive belt. This motion pinches the
drive belt between the spinning sheaves and causes it to rotate,
which in turn rotates the driven clutch.
At lower RPM, the drive belt rotates low in the drive clutch
sheaves. As engine RPM increases, centrifugal force causes the
drive belt to be forced upward on drive clutch sheaves.

WARNING
All PVT maintenance or repairs should be
performed only by a certified Polaris Master
Service Dealer (MSD) technician who has
received the proper training and understands
the procedures outlined in this manual.
Because of the critical nature and precision
balance incorporated into the PVT
components, it is absolutely essential that
no disassembly or repair be made without
factory authorized special tools and
service procedures.
