This V-belt transmits drive torque from the engine pulley to the driven components in the harvester’s drive system. It sits in the pulley grooves and relies on wedge friction to transfer power without slipping. A worn or glazed belt reduces grip, causing speed loss at the driven assembly and potential overheating from belt slip. The belt is constructed with a tensile cord layer and a rubber compound that matches the original profile for correct seating in the pulley grooves. On installation, ensure the belt is not twisted and adjust tension to the manufacturer’s specification for the application.
