ABSTRACT:
A centrifugally disengageable engine starter gear of the positive shift type that has a clutch to provide for driving and indexing of the starter gear, an internal mechanism keeps the clutch teeth in engagement during the indexing function, and a centrifugal separator separates the clutch teeth in an overrunning condition. The separator includes a plurality of flyweight members disposed in a like plurality of flyweight recesses provided in a driven member of the clutch. Radial displacement of the plurality of flyweight members axially displaces a thrust washer to separate the clutch teeth. A projection extending longitudinally from each web which separates the flyweight recesses prevents the flyweight members from disengaging from the flyweight recesses during an overrunning mode.
