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

Initial signs of a failing bearing may include a knocking or rattling sound from the engine, particularly under load. If ignored, the bearing can wear excessively, leading to reduced oil pressure and potential engine damage. Continued operation with a compromised bearing risks severe internal engine component failure.

Installation Tip

Ensure the crankshaft journals are meticulously cleaned and inspected for any scoring or imperfections before installation. Avoid using any abrasive materials on the bearing surfaces during installation.

Service Note

Inspect the crankshaft journals for wear and damage, and ensure proper oil clearance is maintained.
