OEM 281-3588/W2190E0 fan clutch

Part Number: 281-3588 / W2190E0
Application: Caterpillar machines (specifically, some models of the 311, 312, and 314 excavators, as well as the 924H, 928H, and 930H wheel loaders)
Function: The fan clutch is a thermostatically-controlled device that regulates the speed of the engine cooling fan. When the engine is running, the fan clutch allows the fan to spin faster or slower depending on the engine's cooling needs.
Construction: The clutch assembly consists of a clutch disc, a housing, a pulley, and a spring.
Material: The clutch disc is typically made of high-strength steel or cast iron, while the pulley and housing are made of aluminum or other lightweight materials.
Operation: The fan clutch engages and disengages the engine cooling fan depending on the engine's temperature. When the engine is running hot, the fan clutch will engage and spin the fan faster to increase airflow over the engine. When the engine is running cool, the fan clutch will disengage and spin the fan slower to reduce engine load and improve fuel efficiency.
Compatibility: The 281-3588 / W2190E0 fan clutch is designed specifically for use in Caterpillar machines and may not be compatible with other machines or applications.
