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 symptom of a failing bearing is often an audible noise, such as grinding or knocking, emanating from the engine. As the wear progresses, this noise will likely increase in intensity, accompanied by noticeable vibrations. If left unaddressed, the bearing can seize, potentially causing severe damage to the shaft it supports and surrounding engine components.

Installation Tip

Ensure the bearing housing and the shaft surfaces are meticulously clean before installation to prevent premature wear. Never use excessive force or a hammer to press the bearing into its seat; use a proper bearing installer tool.

Service Note

Inspect the shaft for scoring or wear and clean the bearing housing thoroughly before installing a new bearing.
