2436718 Main Bearing Set — Cat 365C

This is a main bearing set designed to support the crankshaft within the engine block, ensuring proper alignment and reduced friction during operation. It is manufactured to meet stringent OEM standards, providing superior durability and wear resistance compared to a worn or damaged bearing. Operators may notice increased engine noise, loss of oil pressure, or a significant decrease in engine performance when these bearings begin 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

Initial signs of main bearing failure may include a knocking or rumbling sound from the engine, particularly under load. If ignored, this noise will intensify, and oil pressure readings may drop significantly. Continued operation risks severe crankshaft and block damage, leading to a complete engine rebuild.

Installation Tip

Ensure the crankshaft and bearing bores are meticulously cleaned before installation to prevent premature wear. Avoid overtightening the main bearing cap bolts, as this can distort the bearing shells and compromise oil clearance.

Service Note

When replacing main bearings, it is crucial to inspect the crankshaft journals for any signs of wear or damage and to check the condition of the connecting rod bearings.
