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

Early indicators of bearing failure include knocking or rattling sounds from the engine, especially under load. If ignored, this can lead to increased oil consumption, reduced oil pressure, and potential engine seizure. The most severe consequence is catastrophic engine damage, requiring a complete rebuild or replacement.

Installation Tip

Ensure the crankshaft journals and bearing surfaces are meticulously cleaned and inspected for any imperfections before installation. Use the correct assembly lube and avoid rotating the crankshaft until all bearings are properly seated.

Service Note

Inspect crankshaft journals, connecting rods, and oil passages for wear or damage when replacing engine bearings.
