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

A failing main bearing may initially cause a low oil pressure warning or a distinct knocking sound from the engine, particularly at lower RPMs. If left unaddressed, this can lead to severe crankshaft damage and potential engine seizure, resulting in significant repair costs and extended downtime. Continued operation risks catastrophic engine failure.

Installation Tip

Thoroughly clean the crankshaft journals and bearing bores, ensuring no debris remains, before installing the new main bearings. Never use abrasive materials to clean bearing surfaces, as this can cause damage.

Service Note

Inspect the crankshaft journals for any signs of scoring or wear, and check the connecting rod bearings for damage when replacing the main bearings.
