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

An initial symptom of bearing failure might be a subtle increase in engine noise or a slight loss of power. If ignored, the noise will escalate to a distinct knocking or grinding sound, and oil pressure may drop. Continued operation risks severe internal engine damage.

Installation Tip

Carefully check the crankshaft journals and bearing caps for any signs of scoring or uneven wear before installation. Ensure the bearing is correctly oriented according to any alignment marks.

Service Note

When replacing this bearing, it is crucial to inspect the crankshaft journals for wear and ensure they are within specified tolerances.
