This multi-ribbed V-belt transmits power from the engine crankshaft to the driven accessories in the drive system. It sits in the pulley set at the front of the engine, routing torque to the alternator, water pump, and fan. The belt has four ribs running its full length, which engage with matching grooves on the pulleys to prevent slip under load. A worn or glazed belt produces a squealing noise at startup and reduces alternator output, leading to a gradual battery drain. Because this is an original AGCO part, the rib profile and belt length match the pulley groove geometry of the original assembly, so no tensioner adjustment beyond the factory specification is needed on installation.
