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 failing 1W1662-040 bearing may first present as a metallic knocking sound from the engine or a noticeable drop in oil pressure. Continued operation can lead to severe internal engine damage, potentially causing a complete loss of engine power. The risk of extensive and costly repairs increases significantly with delayed replacement.

Installation Tip

Before installing, ensure the bearing housing is thoroughly cleaned and free of any old lubricant or debris. Press the bearing in squarely to avoid cocking, which can damage the bearing or housing.

Service Note

When replacing this bearing, it is advisable to inspect the crankshaft or connecting rod for any signs of wear or scoring.
