OE NO. 54-8408

Starter Drives

This starter drive gear assembly is a vital transmission spare part for starter motors. It delivers cranking torque through the one-way clutch and disengages from the flywheel once the engine starts, protecting the starter from reverse rotation damage. It serves as a direct aftermarket replacement for many starter models.

  • Internal Model No: T8408
  • Material: 20CrMnTi
  • Feature: Bottom spring buffer structure absorbs meshing vibration and extends gear service life
  • Application: Automotive starter motors

This starter drive features thick forged gear and a spring buffer base to absorb impact during meshing and reduce gear tooth damage. It locks for power transfer while cranking and freewheels immediately once the engine outruns the starter. Replacing this single component instead of the whole starter helps cut down repair expenses, ideal inventory for auto parts distributors and repair garages.
