  • Internal Model No: T8340A
  • Material: 20CrMnTi
  • Feature: Stable one‑way clutch assembly, sensitive lock‑up and slip‑off, reliable power transmission and effective starter protection;Anti‑rust surface treatment, resistant to oil contamination and temperature variation under harsh engine‑bay conditions.
  • Application: Automotive starter motors

Mounted on starter motor output shaft, the starter drive meshes with engine flywheel ring gear. During cranking, internal one‑way mechanism locks and transfers power to crank the engine.
