PVT SYSTEM OVERVIEW

General Operation

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.
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
recommended. Proper clutch setup and careful
inspection of existing components must be the primary
objective when troubleshooting and tuning.
