This V-belt transmits power from the engine to the drive system of the parent combine harvester. It sits in the pulley train that drives the threshing and separation mechanisms; a slip or break here stops the entire harvesting process. The belt is a classic wrapped V-belt, meaning its sides are covered with a fabric layer that protects the tensile cords and reduces friction against the pulley flanks. A worn or stretched belt causes audible squealing and a gradual loss of driven speed, which leads to uneven crop flow and increased slugging risk in the threshing drum. This belt matches the original cross-section and length profile so that it seats correctly in the pulley grooves without requiring a tensioner adjustment outside the normal range. On installation, verify that the belt runs in the correct rotation direction and that all pulley faces are free of debris or rust.
