This is a CAT Crankshaft, a critical rotating component within the engine that converts reciprocating linear piston motion into rotational torque. It is manufactured to meet stringent OEM quality standards, ensuring superior durability and performance compared to worn or damaged crankshafts. Operators may notice a loss of engine power, increased vibration, or unusual knocking sounds from the engine block when this component begins to fail.
Always verify with serial number before ordering.

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.
Initial signs of a failing crankshaft may include a persistent knocking sound from the engine or a noticeable decrease in engine power. As the issue progresses, excessive vibration may be felt throughout the machine, and oil pressure could drop. Continued operation with a compromised crankshaft risks severe internal engine damage.
Ensure the crankshaft journals are meticulously cleaned and free of any debris before installation. Avoid overtightening main bearing cap bolts, as this can distort the crankshaft and lead to premature failure.
Always replace main and connecting rod bearings when installing a new or reconditioned crankshaft.
