Certain ones of the discs have outer teeth that engage toothed channels in the motor shaft and certain other ones of the discs have inner teeth that engage toothed ribs on the pinion shaft. The discs, toothed channels and toothed ribs cooperate to cause axial engagement and disengagement of the freewheel unit with the motor shaft and pinion shaft.
