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 primary indicator of bearing failure is a persistent knocking sound emanating from the engine, which may worsen under load. Continued operation can lead to significant oil pressure loss and potential engine overheating. The ultimate risk is severe damage to the crankshaft and engine block, necessitating a costly rebuild.

Installation Tip

Carefully clean the crankshaft journals and bearing bores, ensuring no foreign particles are present that could cause immediate damage. Never reuse old bearing bolts; always use new ones with the correct torque specifications.

Service Note

Inspect the crankshaft for any signs of scoring or wear, and consider replacing the connecting rod bearings as well.
