Abstract: An adjustment mechanism for rotating an adjusting ring on a clutch is disclosed. The adjustment mechanism includes a support bracket having an opening therein and a a rotation assembly rotatable about an axis relative to the support bracket. The rotation assembly includes a detent mechanism that is configured to cause both rotational and axial movement of the rotation assembly relative to the support bracket when only a rotational force is applied to the rotation assembly.

Abstract: A friction clutch assembly connects driving and driven shafts and has a pressure plate axially moveable between an engaged position transmitting torque from the driving shaft to the driven shaft and a disengaged position. The assembly includes levers and a plurality of centrifugal-assist weights on the levers adjacent outer ends of the levers. The centrifugal-assist weights are arranged to apply an increased force urging the pressure plate to its engaged position upon rotation of the cover and the levers. The centrifugal-assist weights are suitably configured to provided the desired amount of increased force.
