Starter Drives

This starter overrunning drive gear is an essential spare‑part for the starter. It ensures proper torque transmission during engine cranking and protects the starter from damage caused by flywheel reverse drive, suitable for aftermarket replacement of many popular starter motors.

  • Internal Model No: T157B
  • Material: 20CrMnTi
  • Feature: Roller‑type one‑way assembly fatigue‑tested to resist premature slip‑failure
  • Application: Automotive starter motors

Many cranking failures are not caused by a burnt‑out motor, but by a failed overrunning clutch: the gear spins idly with no firm engagement, resulting in a clicking noise while the engine won’t turn over. Forged and precision‑bored, this drive gear features a dependable one‑way locking mechanism.
