This V-belt transmits rotational force from the engine crankshaft to the fan hub, driving the cooling fan that pulls air through the radiator core. It sits on the front of the engine, routed around the fan pulley and the crankshaft damper pulley. A worn or glazed belt slips under load, reducing fan speed and causing coolant temperature to rise, especially during heavy field work. The belt is manufactured to match the original cross-section and length so it seats correctly in the pulley grooves without requiring a tensioner adjustment beyond the standard range.
