2436716 Main Bearing Set — Cat 12H 12M 2

This is a set of main bearings designed to support the crankshaft within the engine block, ensuring proper alignment and reducing friction during combustion cycles. Manufactured to precise tolerances and material specifications, these bearings provide superior load-bearing capacity and wear resistance compared to a worn set that exhibits excessive clearance and oil film breakdown. Operators may notice a significant drop in oil pressure, knocking sounds from the engine, or a general loss of engine power when these main bearings 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 persistent knocking or rumbling sound from the engine, especially under load, accompanied by a noticeable drop in oil pressure. If ignored, this can lead to severe crankshaft and block damage, potentially causing complete engine seizure. Continued operation risks catastrophic engine failure and extensive repair costs.

Installation Tip

Ensure the crankshaft journals and bearing surfaces are perfectly clean and free of any debris before installation. Never reuse old bearing bolts; always use new, properly torqued fasteners.

Service Note

Always inspect the crankshaft journals for wear, scoring, or out-of-roundness, and check connecting rod bearings when replacing the main bearing set.
