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

Initial signs of a failing drive gear assembly include whining or grinding noises from the transmission, especially under load. Continued operation will lead to increased vibration and a significant loss of torque or drive power. The ultimate consequence is the potential for gear tooth breakage, leading to complete loss of drive and possible damage to other drivetrain components.

Installation Tip

Thoroughly clean the gear housing and inspect all mating surfaces for wear or damage before installing the new gear assembly. Ensure proper alignment and lubrication during installation to prevent premature wear.

Service Note

Inspect the transmission fluid for metal particles and check all associated bearings and seals for wear when replacing a drive gear assembly.
