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

Intermittent operation or complete failure of an electric motor is a common symptom of a worn brush plate. If ignored, the motor may cease functioning entirely, leading to downtime. The risk is the loss of a critical function powered by that motor.

Installation Tip

Ensure the new brush plate is precisely aligned with the motor housing to prevent binding. Do not overtighten the mounting screws, as this can warp the plate or damage the threads.

Service Note

Always inspect the motor brushes for wear and the commutator surface for damage when replacing the brush plate.
