PVT BREAK-IN (DRIVE BELT / CLUTCHES)
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 10 hours as recommended (see Chapter 3 –
Engine Break-In Period, page 3.37 for break-in
example). Pull only light loads. Avoid aggressive
acceleration and high speed operation during the break-
in period.
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 clutch
stationary sheave. 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.
