The conventional starter motor contains the components shown. The pinion gear is on the same shaft as the motor armature and rotates at the same speed. A plunger in the magnetic switch (solenoid) is connected to a shift lever. When activated by the plunger, the shift lever pushes the pinion gear and causes it to mesh with the flywheel ring gear. When the engine starts, an over-running clutch disengages the pinion gear to prevent engine torque from ruining the starting motor.
This type of starter was used on most 1975 and older Toyota vehicles. It is currently used on certain Tercel models. Typical output ratings are 0.8, 0.9, and 1.0KW. In most cases, replacement starters for these older motors are gear-reduction motors.
