This V-belt transmits power from the engine to the threshing mechanism within the combine harvester. It runs on a multi-groove pulley system that drives the threshing drum and related rotating assemblies. A worn or slipping belt reduces threshing speed, leading to incomplete separation and increased grain loss. The belt is constructed by Gates to match the original cross-section and pitch length, ensuring proper tension and alignment with the pulley grooves without requiring shimming or modification. On installation, verify the belt sits fully in each pulley groove and adjust the tensioner to the specified deflection.
