2436717 Main Bearing Set — Cat 14M 16M

This main bearing set is engineered to support the engine's crankshaft, providing a low-friction surface for its rotation within the engine block. It is essential for maintaining engine balance, oil pressure, and overall power output. Failure of these bearings can result in audible knocking, significant loss of oil pressure, and potential engine seizure, requiring immediate attention.

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 noticeable symptom of main bearing failure is often a deep knocking sound originating from the engine, especially under load. If operation continues, this noise will intensify, oil pressure will drop, and severe internal engine damage is likely.

Installation Tip

Ensure that the crankshaft journals are thoroughly cleaned and inspected for any imperfections before installing the new bearing set. Proper alignment of the bearing halves is crucial to prevent premature failure.

Service Note

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