This V-belt transmits power from the engine crankshaft to the fan drive pulley on forage machines. It sits in the drive system between the crankshaft and the fan hub, maintaining the rotational speed needed for cooling airflow through the radiator and engine compartment. A worn or slipping belt reduces fan speed, which can cause elevated coolant temperatures and reduced engine efficiency under load. Gates manufactures this belt to match the original cross-section profile, ensuring proper seating in the pulley grooves without requiring tensioner adjustment beyond the standard range. On installation, verify the belt rides flush in each pulley groove and tension to the specification for the host machine.
