CATBearing & Bushing

1496035 Main Bearing — Cat 3508 3512

This is a main bearing designed to support the rotating crankshaft within the engine, ensuring precise alignment and minimizing friction. Manufactured to meet rigorous CAT specifications, it provides exceptional durability and wear resistance, unlike a worn bearing that may exhibit scoring, cracking, or excessive clearance. Operators may observe a drop in oil pressure, knocking sounds from the engine, 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

A failing main bearing may first present as a persistent knocking sound from the engine that increases with RPM, or a significant and unexplained drop in oil pressure. If ignored, the bearing can completely fail, leading to crankshaft damage, potential engine seizure, and extensive repair costs. Continued operation risks catastrophic engine failure.

Installation Tip

Ensure the crankshaft journals and bearing surfaces are meticulously cleaned and lubricated with clean engine oil before installation. Never reuse old bearing caps or mix bearing sets, as this can lead to improper alignment and premature failure.

Service Note

Always replace main bearings in sets and inspect the crankshaft journals for any signs of scoring, wear, or out-of-roundness.
