Description: Built for construction site heavy cycles, this S6K/3066 crankshaft withstands frequent shock and high load. Nitrided bearing surfaces slow down wear, while reinforced fillets resist fatigue fracture. Each unit is checked one by one before delivery to keep engine running smoothly.
A robust rotating core for CAT 6-cylinder diesel engine used on E320B & E320C excavators.
✔ High strength raw material for harsh working conditions
✔ Nitrided journals for long wear life
✔ Precision balanced to cut vibration
✔ Ready-to-fit for engine rebuild
This crankshaft is engineered exclusively for CAT S6K and 3066 series diesel engines, the common power unit fitted on CAT E320B and E320C excavators. Construction machinery operates under unpredictable heavy loads and vibration, so we adopt high-strength forged steel or nodular cast iron for this crankshaft. All journals are finely ground and nitrided to boost surface hardness. Fillet rolling process greatly improves fatigue performance to avoid unexpected breakage. We implement full inspection including dimension verification and dynamic balance testing. Consistent tolerance ensures seamless assembly and stable power output during long-hour excavation work. It is a reliable aftermarket solution for repair shops and fleet maintenance.
