3655704 Fan Pulley

This 3655704 fan pulley is engineered for Cummins NH, NT 855, NTC, NH, and N14 series engines. Precision-cast from high-strength ductile iron with a dynamically balanced design and CNC-machined mounting surfaces, it delivers exceptional rotational stability, smooth belt drive, and long-term durability. The pulley drives the engine's cooling fan, ensuring consistent airflow through the radiator and maintaining optimal engine operating temperatures. Its robust construction withstands the rigors of heavy-duty use, preventing belt slippage, vibration, and component failure for thousands of operating hours. It is the ideal replacement for maintaining your engine's cooling system performance.
