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
hour break-in period as recommended (see Chapter 3
“Engine Break-In Period” 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, Drive to Driven Clutch
Alignment, and Clutch Center Distance.
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 appropriate
illustrations 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.
