2611544 Crankshaft W/Gear — Cat 12H 140M

This is a CAT Crankshaft with Gear, the central rotating shaft in an engine that converts reciprocating motion into rotational motion, essential for power generation. It is precision-balanced and forged from high-strength steel to endure extreme combustion forces and wear, unlike a worn crankshaft with bearing journal damage or imbalance. Operator symptoms of a failing crankshaft include severe engine vibration, knocking sounds from the crankcase, and a significant loss of engine power or complete shutdown.

Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

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 a crankshaft issue is often a deep knocking sound originating from the engine crankcase, accompanied by excessive vibration. As the problem worsens, the engine may lose significant power, and oil pressure could drop due to bearing damage. Continued operation risks catastrophic engine failure, potentially causing extensive damage to the engine block and other internal components.

Installation Tip

Ensure all crankshaft bearing journals and the corresponding bearing shells are meticulously cleaned and properly lubricated before installation. Never reuse old bearings; always install new ones with the crankshaft.

Service Note

Always replace the main bearings and connecting rod bearings when installing a new or reconditioned crankshaft.
