This multi-ribbed V-belt transmits power from the engine crankshaft to the drive system accessories and auxiliary loads. It runs on the pulleys of the alternator, water pump, and air-conditioning compressor, synchronizing their rotation with the engine. A worn belt slips under load, causing undercharging, overheating, or reduced hydraulic flow. The original AGCO belt is molded to the same rib profile and pitch length as the factory-installed belt, so it seats fully in the pulley grooves without crowning or edge wear. On installation, verify the belt tensioner is within its working range and that the belt tracks centered on all pulleys.
