CATBearing & Bushing

1450170 Main Bearing — Cat Engine: 3114 3116

This is a CAT Main Bearing designed to support the rotating crankshaft within an engine. Manufactured to exact OEM specifications, it ensures proper oil film formation and load distribution for optimal engine performance, unlike a worn bearing that can lead to increased friction and potential crankshaft damage. Operators might notice a knocking sound from the engine, reduced oil pressure, or a general loss of engine power when this main bearing begins to fail.

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

The first indication of main bearing failure is often a deep knocking sound from the engine, especially under load, accompanied by a drop in oil pressure. If ignored, this can lead to severe crankshaft damage, bearing seizure, and catastrophic engine failure. Continued operation risks irreparable damage to the engine block and crankshaft.

Installation Tip

Ensure the crankshaft journals and bearing surfaces are meticulously cleaned and free of any debris or scoring before installation. Never reuse old bearing cap bolts; always use new ones torqued to specification.

Service Note

Inspect the crankshaft journals for wear or damage, check connecting rod bearings, and verify oil pressure.
