491-5234 Crankshaft — Cat 320 320Gc

This crankshaft is the central rotating shaft for the engine, converting reciprocating motion into rotational power. Manufactured to precise OEM standards, it ensures smooth operation and optimal power transfer, unlike a worn crankshaft with excessive play or cracks. Operators may notice unusual engine noises, vibrations, or a significant loss of power when a crankshaft begins to fail.

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

Initial signs of crankshaft failure can include knocking or rumbling sounds from the engine, especially under load. This can progress to severe engine vibration and a noticeable reduction in power output. Continued operation risks catastrophic internal engine damage.

Installation Tip

Ensure all bearing surfaces on the crankshaft and in the engine block are meticulously cleaned and lubricated before installation. Avoid dropping or striking the crankshaft during handling to prevent damage to journals.

Service Note

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