SHIFT WEIGHTS

Shown below are optional shift weights which may be used in the PVT system. These shift weights have many
different factors designed into them for controlling engagement RPM and shifting patterns. Shift weights should
not be changed or altered without first having a thorough understanding the effects they have on belt to sheave
clearance, clutch balance, engagement and shifting characteristics.
