ABSTRACT:
A centrifugal, shaft-driven clutch apparatus includes an engine shaft for providing rotary power, the engine shaft having a free end portion and an open ended bore that communicates with the free end portion. A centrifugal clutch assembly includes a clutch bushing member having a shaft bore for affixing the bushing member to the shaft. The bushing member provides an internal bore and an outer surface. The clutch assembly includes a clutch housing member with an internal bore, and the clutch housing rotates upon the clutch bushing member at the internal bore. A first port extends between the shaft bore and the clutch bushing for transmitting lubricant from the shaft bore to the clutch bushing member. A second port extends through the bushing member bore to the outer surface thereof. A channel forms a communication between the first and second ports for transporting lubricant between the first and second ports. A fitting provides an inlet portion for receiving lubricant, and is attached to the shaft bore. The fitting includes an enlarged head portion that retains the clutch assembly upon the shaft during use.
