6i1453 Crankshaft A W/Gear — Cat 16G 16H NA

This crankshaft is a core component of the engine's rotating assembly, converting the linear motion of the pistons into rotational force. Manufactured to high standards, it offers superior strength and durability compared to a worn crankshaft with bearing journal damage or fatigue cracks. Operators might observe a significant loss of engine power, unusual knocking sounds from the engine block, or excessive engine vibration if the crankshaft is compromised.

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

Early indications of a failing crankshaft can include persistent engine knocking sounds, a noticeable drop in oil pressure, or increased exhaust smoke. As the failure progresses, these symptoms will worsen, leading to severe engine vibration and potential seizure. Continued operation risks catastrophic engine damage.

Installation Tip

Ensure all bearing journals are meticulously cleaned and lubricated with assembly lube before installation. Never reuse old bearing shells; always install new ones matched to the crankshaft.

Service Note

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