AGCO - 4285560M3 - Multi-Ribbed Fan Drive Belt Massey Ferguson

This multi-ribbed belt drives the engine cooling fan from the crankshaft pulley. It sits in the front-end accessory drive system, maintaining tension across the pulleys to keep the fan rotating at the correct speed for engine cooling. A slipping or worn belt reduces airflow through the radiator, which can cause elevated coolant temperatures under load. As an original-manufacturer component, its rib profile and belt length match the pulley groove geometry of the assembly it was designed for, so no tensioner adjustment beyond the standard range is needed. On installation, verify that the belt tracks centrally on all pulleys before applying tension.
