Starter Drives

This starter drive serves as core protection for vehicle starting system. It solves the common failure that starter cannot disengage after cranking and gets burnt by high‑speed reverse drag from flywheel.

  • Internal Model No: T8333A
  • Material: 20CrMnTi
  • Feature: Quench‑hardened pinion teeth for great impact resistance, reduce chipping & wear from repeated meshing;Built‑in wear‑resistant copper bushing reduces shaft friction for extended service life
  • Application: Automotive starter motors

This overrunning clutch matches designated automotive starter assemblies. Its precision internal roller mechanism locks torque for forward drive and allows free slip in reverse direction. Pinion meshes with flywheel to deliver cranking torque; once engine ignites and revs up, internal unit slips instantly to block reverse power feedback.
