ABSTRACT:
A starter drive for an internal combustion engine has a plunger pole starting motor drivably connected to a pinion adapted to engage the ring gear on the engine when cranking the engine. A shift fork is pivotally mounted on a lever arm connected to the plunger pole and a single spring urges the shift fork to position the pinion in cranking position when the motor is energized and returns the shift fork to position the pinion in non-cranking position when the motor is deenergized. Space is made available for a cushioning device between the motor and pinion to absorb starting torque.
