This V-belt transmits power from the engine drive pulley to the header and threshing mechanisms on a grain harvester. It sits in the drive system, routing torque to the rotating assemblies that feed and process the crop. A worn or slipping belt reduces drum speed, leading to incomplete threshing and increased material loss out the rear of the machine. Gates manufactures this belt to the original cross-section and length specification, so it seats correctly in the pulley grooves without requiring tensioner adjustment beyond the standard range. On installation, verify the belt tracks straight on all pulleys and tension it to the manufacturer’s deflection specification.
