Abstract
A centrifugal actuator is provided for a centrifugal clutch. The centrifugal clutch includes a drive spider having a cam lever-following roller and a moveable clutch housing. The centrifugal actuator includes two bosses, each boss having a mechanism for coupling to the clutch housing. Each boss is formed to include a pin-receiving opening. The bosses are arranged in spaced-apart relation on the clutch housing to form a central slot therebetween. A cam lever having an interior wall arranged to define a D-shaped pin-receiving opening is positioned to lie in the central slot and is arranged to pivot to maintain engagement of the cam lever and the cam lever-following roller. A pivot pin is rotatably received in the pin-receiving openings of the two bosses and the D-shaped pin-receiving opening of the cam lever. The pivot pin includes an elongated flat exterior wall and an elongated curved exterior wall arranged so that a transverse cross section of the pivot pin is D-shaped. The entirety of the interior wall of the cam lever engages the pivot pin.
