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

A persistent knocking or rattling sound emanating from the engine is the first indication of bearing failure. If ignored, this noise will intensify, accompanied by a noticeable drop in oil pressure and potential engine overheating. Continued operation risks severe crankshaft and connecting rod damage, leading to a complete engine seizure.

Installation Tip

Ensure the crankshaft journals are meticulously cleaned and free of any debris before installation. Avoid reusing old bearing bolts, as they can stretch and lead to improper clamping force.

Service Note

Inspect the crankshaft journals for scoring or wear, and check the oil pump for proper pressure output when replacing connecting rod bearings.
