Fendt G117202040100 Viscous Fan Clutch Assembly

The Fendt G117202040100 is a viscous fan clutch (viscous coupling) designed for the engine cooling system of Fendt Farmer series tractors. It modulates fan speed via a thermostatic bimetallic strip actuating a silicone fluid coupling, reducing parasitic engine load and noise during low cooling demand. This unit serves as a direct OEM replacement for Fendt part numbers G117.202.040.100 and G117202040100. Verified fitment includes Fendt Farmer 307, Farmer 308, and Farmer 309 models. Cross-references include 655060017, AM-20003144-M (BorgWarner), and G117202040010. Constructed with a sealed fluid chamber, precision bearings, and a bi-metal thermal actuator for maintenance-free operation.
