This multi-ribbed engine belt transmits power from the crankshaft pulley to the alternator, water pump, and other auxiliary drives on the host tractor. It is a 10PK-profile V-ribbed belt, designed to maintain tension across the full accessory load range. A worn or glazed belt slips under load, causing undercharging, overheating, or reduced hydraulic flow. As an original AGCO component, the belt is molded to the same rib profile and pitch length as the factory-installed belt, so it seats correctly in every pulley groove without forced alignment. On replacement, inspect the tensioner and idler pulleys for bearing wear and set belt tension to the manufacturer's specification.
