CATBearing & Bushing

1W1662- 030 Bearing — Cat 953 Engine: 3204

This is an engine bearing, specifically a main or connecting rod bearing, crucial for the smooth operation of the crankshaft within the engine block. Manufactured to meet stringent OEM quality standards, it offers superior wear resistance and load-carrying capacity compared to a worn bearing showing signs of scoring or deformation. Operators may experience a noticeable increase in engine noise, a drop in oil pressure, or rough running if this bearing fails.

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 bearing may first present as a distinct knocking or rattling sound from the engine, often more pronounced under acceleration. If ignored, this can progress to significant oil pressure loss and increased engine vibration. Continued operation risks severe crankshaft and engine block damage.

Installation Tip

Ensure the crankshaft journals are perfectly clean and free of any burrs or imperfections before seating the bearing. Never reuse old bearing bolts; always use new ones with the correct torque specification.

Service Note

Always replace main bearings in sets and inspect the crankshaft journals for wear and straightness.
