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.
