Installation & Application Notes

Never strike bearings directly — use a bearing press or driver set. Heat housing (not bearing) to ease installation. Replace bearings in sets where applicable. Check housing bore diameter before fitting — out-of-round bores destroy new bearings.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

Failure often begins with a knocking or rattling sound from the engine, especially under load. As the bearing wears, oil pressure may drop, and the engine temperature can rise significantly. Continued operation risks catastrophic engine damage due to the loss of critical rotational support.

Installation Tip

Ensure the crankshaft journals and bearing surfaces are perfectly clean and free of any abrasive material before installation. Never reuse old bearing bolts; always install new ones with the correct torque specifications.

Service Note

When replacing engine bearings, it is essential to check crankshaft journal runout and surface finish for any imperfections.
