Fan Clutch Hub

A Fan Clutch Hub is a component of the Engine Cooling System in non-aircraft engines. It belongs to the supply class Engine Cooling System Components and falls under the supply group Engine Accessories.

The Fan Clutch Hub is responsible for controlling the operation of the engine cooling fan. It is typically located between the engine and the fan blade assembly. The main purpose of the Fan Clutch Hub is to regulate the speed of the cooling fan based on the engine's temperature.

When the engine is running at normal operating temperatures, the Fan Clutch Hub allows the fan to rotate freely, resulting in reduced drag on the engine and improved fuel efficiency. However, when the engine temperature rises above a certain threshold, the Fan Clutch Hub engages and locks the fan to the engine, causing it to rotate at a higher speed. This increased airflow helps to cool down the engine and prevent overheating.

The Fan Clutch Hub is designed to automatically adjust the fan speed based on the engine's cooling needs. This helps to optimize the cooling system's performance and ensure efficient engine operation.

Overall, the Fan Clutch Hub plays a crucial role in maintaining the proper temperature of the engine by regulating the operation of the cooling fan.
