AGCO - 4378107M1 - Massey Ferguson Alternator V-Belt

This V-belt transmits drive from the engine crankshaft to the alternator pulley. It sits in the accessory drive system, where it maintains tension to keep the alternator spinning at the required speed for charging the battery and powering electrical loads. A worn or glazed belt slips under load, causing the alternator output voltage to drop and the battery to discharge. This original belt matches the cross-section and length required by the tensioner and pulley system, so no adjustment shimming is needed.
