Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Repair and Diagnosis: Electrical: Starter: Description
Two types of starter motors are used, conventional and reduction gear. Both types of starters consist of yoke assembly, armature assembly, overrunning clutch assembly, separate plunger-style solenoid (magnetic switch) assembly, drive end frame (housing), rear end frame (commutator end housing), brush holder and drive lever. Reduction gear type starter also has a reduction gear assembly combined with shock absorber mechanism.
With ignition in START position, solenoid is activated. Yoke engages starter pinion and overriding clutch assembly with flywheel gear and closes solenoid contacts, energizing starter motor. When engine starts, an overrunning clutch assembly protects armature from excessive speed until switch is opened. A return spring disengages pinion from flywheel gear.
