Abstract A starter drive for internal combustion engines is disclosed. The starter drive is mounted within the starter housing and connected to the motor driven shaft. The shaft has a threaded screw formed thereon near the armature of the starter and a cylindrical end portion. A screw sleeve member cooperatively engages the threaded screw of the motor driven shaft. A ring armature member is centrally mounted to the threaded screw member. A unidirectional clutch member connects the screw sleeve member, the ring armature member and the drive pinion gear. An engaging member holds the ring armature member to the starter housing when the drive pinion is advanced axially along the motor driven shaft by the rotation of the motor when the motor is activated. Thus, the drive pinion engages the engine ring gear such that the drive pinion is held in mesh with the engine ring gear and the total motor torque is transmitted to the engine ring gear until the motor is deactivated.
