Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

The first indication of a failing gear assembly might be an audible clicking or grinding noise from the engine. If ignored, the noise will likely increase, and the engine may experience vibrations or a loss of power due to improper timing. Continued operation risks damage to adjacent components in the drive train.

Installation Tip

Carefully inspect the mating surfaces and teeth of the old gear for signs of wear or damage before removal. Ensure the new gear is seated flush and rotates freely by hand before final assembly.

Service Note

Inspect the condition of the drive shaft and any associated bearings when replacing the gear assembly.
