PVT BREAK-IN
A proper break-in of the clutches and drive belt will
ensure a longer life and better performance. Break in the
clutches and drive belt by operating at slower speeds
during the 25 hours as recommended. Refer to “Engine
Break-In Period”page 3.32 for break-in example). Avoid
aggressive acceleration and high speed operation during
the break-in period. After installation of a new drive belt,
break-in new drive belts by operating at slower speeds
during the break-in period ~50 miles. Carry only light
loads. Avoid aggressive acceleration, high speed
operation, and extended time at a specific RPM during
the break-in period. In addition, when operating in sand/
dune environments, avoid extended low speed operation
at high throttle.
Sand / Dune Break-In
Drive in low gear for the first 5 miles (8 km) of operation.
Avoid prolonged low speed operation at high throttle.
Avoid aggressive acceleration, high-speed operation and
prolonged operation at a specific RPM during this period.
PVT SYSTEM MAINTENANCE / INSPECTION
Under normal use the PVT system will provide years of
trouble free operation. Periodic inspection and
maintenance is required to keep the system operating at
peak performance. The following list of items should be
inspected and maintained to ensure maximum
performance and service life of PVT components. Refer
to the troubleshooting checklist at the end of this chapter
for more information.
1. Belt Inspection.
2. Drive and Driven Clutch Buttons and Bushings, Drive
Clutch Shift Weights and Pins, Drive Clutch Spider
Rollers and Roller Pins, Drive and Driven Clutch
Springs.
3. Sheave Faces: Clean and inspect for wear.
4. PVT System Sealing: Refer to the appropriate
illustration(s) on the following pages. The PVT system
is air cooled by fins on the drive and driven clutch
stationary sheaves. The fins create a low pressure
area in the crankcase casting, drawing air into the
system through an intake duct. The opening for this
intake duct is located at a high point on the vehicle
(location varies by model). The intake duct draws
fresh air through a vented cover. All connecting air
ducts (as well as the inner and outer covers) must be
properly sealed to ensure clean air is being used for
cooling the PVT system and also to prevent water and
other contaminants from entering the PVT area. This
is especially critical on units subjected to frequent
water forging.
