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 bearing may include a faint knocking sound from the engine that increases with RPM. If ignored, the bearing can wear further, leading to reduced oil pressure and potential engine seizure. Continued operation risks severe damage to the crankshaft and connecting rods.

Installation Tip

Ensure the crankshaft journals are meticulously clean and free of any burrs or imperfections before installation. Avoid using abrasive materials to clean the bearing surfaces, as this can compromise their integrity.

Service Note

Always inspect the crankshaft journals for any signs of scoring or wear when replacing engine bearings.
