🔍 Key Concepts

• Starter motor drive mechanism shown at labels E, F, G, and H • How an overrunning (one‑way) clutch protects the starter when the engine reaches its own speed • Difference between centrifugal/centripetal force versus mechanical one‑way rotation

💭 Think About

• When the engine fires and begins to spin the flywheel faster than the starter, what must happen to the small pinion gear at H so the starter is not driven like a generator? • Which component in the illustration actually disconnects the pinion gear from the armature shaft when the flywheel ‘overtakes’ it—an electrical switch, stored spring energy, or a one‑way mechanical clutch? • Look at the splined sleeve and the clutch near G: in which direction can it transmit torque, and what happens when the flywheel tries to drive it the opposite way?

✅ Before You Answer

• Identify which part in the picture is the overrunning (one‑way) clutch and which is just the solenoid plunger and spring • Confirm whether any centrifugal mechanism is actually drawn in the armature or commutator area • Trace the torque path from the armature to the pinion and back, and note what happens when the flywheel speed exceeds starter speed
