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

Early signs of bearing failure include audible knocking or rattling sounds from the engine, especially under load. If ignored, the noise will intensify, and oil pressure may drop, potentially leading to severe internal engine damage. Continued operation risks catastrophic engine seizure.

Installation Tip

Ensure all bearing surfaces and the corresponding journals are meticulously cleaned and free of any abrasive particles before installation. Use the correct lubricant on bearing surfaces during assembly to prevent initial scoring.

Service Note

Inspect the crankshaft and connecting rod journals for scoring or wear when replacing this bearing.
