Dongfeng Cummins 410107700 Alternator Pulley

The 410107700 alternator pulley is engineered for Dongfeng Cummins QSB6.7 and ISME series diesel engines. It features an 8PK poly-V groove profile designed for 28V 70A alternator assemblies including OEM references 5343811 and 215226. The component transmits rotational torque from the engine crankshaft via the serpentine belt to the alternator rotor, maintaining precise belt alignment and tension stability under high-speed operation. Constructed from high-strength steel with a corrosion-resistant surface treatment, the pulley withstands thermal cycling and vibration inherent in heavy-duty commercial vehicle duty cycles. It serves as a direct replacement for the alternator drive pulley on Dongfeng Tianlong flagship tractors, dump trucks, cement mixers, and bus chassis equipped with ISME420 30 and ISDe powerplants. Dimensional accuracy ensures compatibility with OEM belt tensioner and idler pulley assemblies.
