Шкив всасывающего вентилятора двигателя Caterpillar 386-4791

An Engine Suction Fan Pulley connects to the fan drive system, enabling the suction fan to draw air through the radiator and other cooling elements. As the pulley rotates, it transfers mechanical power to the fan blades, creating airflow that pulls cooler ambient air through the cooling fins and over the engine components. It supports smooth and efficient fan operation under continuous load, even in high-temperature and dusty environments. Attributes:• Prevents overcooling by maintaining fan speed balance.• Supports smooth start-up of the fan during engine operation.• Ensures the fan draws sufficient air through the radiator for cooling.Applications: An Engine Suction Fan Pulley is mounted on the fan drive assembly and connected to the belt system, enabling the suction fan to pull air through the radiator to regulate engine temperature.
