McNeilus Fan Clutch-2Spd Ism C12

McNeilus Fan Clutch-2Spd Ism C12

This is a Horton DriveMaster two-speed fan clutch for McNeilus rear discharge concrete mixers that use a Cummins ISM engine. The fan clutch is a critical powertrain cooling component that controls the engine's cooling fan, engaging at high speed when maximum cooling is needed and running at a lower speed or disengaged when it's not, which saves horsepower and fuel. This specific model is a rear air-actuated clutch. It is a necessary replacement part for vehicles experiencing engine overheating or a non-functioning fan, ensuring the engine is protected during high-load situations common in the ready-mix industry.
