14.1 Preparation of materials

Points for attentions
During the operation, oil is not allowed to be left on the surface of v-shaped belt. It should be removed if there is
any oil left so as to reduce the slippage between v-shaped belt and pulley.
Function:
Driving plate/clutch/driven wheel constitute continuously variable transmission (CVT) together. The
torque is transmitted through v-shaped belt between the driving plate and driven wheel.
