General Instructions
Automatic Torque Converter System
The torque converter system automatically regulates the torque delivered by the
engine to the transmission. The System consists of a driver clutch located on the
engine output shaft, a driven clutch located on the input shaft of the transmission,
and a drive belt.
On acceleration, the driver clutch movable face travels towards the fixed face as the
weights in the clutch are pushed outwards due to centrifugal force. This in turn
compresses the internal spring of the driver clutch. As the driver clutch faces narrow,
they grip the drive belt moving it towards the top of the driver clutch. (Top No Load
Speed). At the same time the transmission’s driven clutch plates spread apart as the
belt rides down between the faces. The tension in this clutch is also regulated by a
spring. As the vehicle comes under load, the spring loaded cam on the driven clutch
forces the clutch plates together, causing the CVT to “Back Shift”.
At idle the belt should rest flush or a little beyond the edge of the driven clutch on the
transmission. At top no load speed the belt should run near or to the top of the driver
clutch.
Worn or dirty clutch components, or a worn drive belt will make the Centaur unreliable
and unsafe to operate.
