Starter Drives

This long-shaft starter one-way clutch is an integrated transmission component inside the starter motor, combining spline drive shaft, overrunning clutch and drive gear.

  • Internal Model No: T8602
  • Material: 20CrMnTi
  • Feature: Precisely built-in overrunning clutch, sensitive response, stable torque transmission in forward direction and fast idle release in reverse direction.
  • Application: Automotive starter motors

When the starter powers on, the one-way clutch transfers power through the long spline shaft, and the front gear meshes with the flywheel ring gear to rotate the engine.
