ABSTRACT:
An engine starter gear of the positive shift type has a clutch to provide driving, indexing, means for keeping the clutch teeth in engagement during the indexing function, and a centrifugal separator to separate clutch teeth in an overrunning condition. The separator includes spherical members retained in an annular retainer member, which spherical members move radially outward of the shaft as the engine accelerates to transmit axial thrust against an inclined surface on an annular ring member to displace the driving clutch member from the driven clutch teeth. The axial thrust on the annular ring member causes separation of the clutch teeth in an overrunning or overspeed condition.
