Effects of Driven Clutch Spring
Increases in driven clutch spring preload will raise engine speed before the clutch starts shifting, allowing the
clutch to backshift more quickly. Decreases in driven clutch spring preload will result in faster upshift, but will also
slow backshift, thereby lowering engine RPM.
It is important to note that engine drive clutch calibration should be used to control engine speed rather than driven
clutch spring preload. Lowering RPMs by decreasing driven clutch spring preload will result in belt slippage on
acceleration. Increasing RPMs by increasing preload will result in excessive drive belt wear and decreased trans-
mission efficiency.
Refer to the chart on page 4.9 for available driven clutch springs. Experimenting with these springs will allow you
to find the most efficient combination of side pressure and back shifting for your application.
Spring tails in line - when installed
in clutch preload will cause tails
to be offset.
CLUTCHING
Spring tails offset - when installed
in clutch preload will cause tails
to be very close to being in line.
