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

The first noticeable symptom is often an audible knocking or rattling noise from the engine, particularly when it is under load. If ignored, this can lead to a significant drop in oil pressure and potential engine overheating. The ultimate consequence is severe damage to the crankshaft and engine block, requiring extensive repairs.

Installation Tip

Thoroughly clean the crankshaft journals and the bearing housings in the engine block before installation. Ensure the correct bearing orientation and cap alignment are maintained.

Service Note

Inspect the crankshaft journals for any signs of wear or damage, and it is advisable to replace the connecting rod bearings at the same time.
