Abstract
A starting system for an internal combustion engine includes a pinion gear selectively driven by a starter motor, a drive plate having a set of teeth in constant meshed engagement with the pinion gear and a one-way clutch adapted to interconnect the drive plate and an engine crankshaft. The clutch assembly includes an inner race adapted to be fixed for rotation with the crankshaft. An outer race is fixed for rotation with the drive plate and has circumferentially spaced apart cam surfaces. The clutch also includes a cage for positioning rollers in circumferentially spaced apart alignment with the cam surfaces. A pair of seal plates are coupled to one of the inner race and the outer race. Each seal plate is positioned proximate to and spaced apart from the other of the inner race and the outer race.
