1496034 Main Bearing — Cat 3508 3512

This is a critical main bearing designed to support the crankshaft within the engine block, ensuring proper rotation and power transfer. Manufactured to exacting OEM standards, it provides superior load-bearing capacity and wear resistance compared to a worn or damaged bearing. Operators may notice a significant drop in oil pressure, knocking sounds from the engine, or a general loss of 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

A failing main bearing often presents as a deep knocking sound from the engine, particularly under load, and a noticeable drop in oil pressure. If ignored, the bearing can disintegrate, leading to crankshaft damage and potential engine seizure. This necessitates a complete engine rebuild or replacement.

Installation Tip

Ensure the crankshaft journals and bearing bores are perfectly clean and free of any debris or scoring before installing the new bearings. Use a proper bearing lubricant on the bearing surfaces and the crankshaft journal during assembly.

Service Note

When replacing main bearings, it is crucial to inspect the connecting rod bearings and the crankshaft for any signs of wear, scoring, or out-of-roundness.
