US 7,097,020 B2 · Throwout bearing lever with dynamic adjustable weight assembly

Abstract

A throwout bearing lever for a centrifugal clutch having a dynamic adjustable weight assembly. The lever comprises a lever having an assembly aperture through the lever and an adjustment screw aperture in communication with the assembly aperture. A threaded adjustment screw within the adjustment screw aperture has a resilient member seat and an adjusting tool receiving seat. A sliding carrier slideable within the assembly aperture has a fastener aperture through the carrier and a resilient member seat. A weight fastener fastens a weight to the carrier. A resilient member seated against the resilient member seats resiliently biases the carrier against an end of the assembly aperture. The threaded adjustment screw allows for adjustment of the resiliency of the resilient member. The assembly slides within the assembly aperture, changing the weight distribution of the lever effecting movement of the lever during operational movement of the clutch.
