A direct-fit replacement 12V 115A alternator for the John Deere 6420, 6510, 6520, 6610, 6620, 6820, 6910, 6920, and 7420 tractor range and associated agricultural applications. The alternator generates AC electricity as the engine runs, which is converted to DC power to charge the battery and supply the vehicle's electrical system. A failing alternator typically presents as a flat battery that will not hold charge, dimming lights under load, or complete electrical failure even with a known good battery.
Manufactured to OEM specification with internal regulator, internal fan, clockwise rotation, and 8-groove pulley with 50mm outer diameter, cross-referencing John Deere OEM part number AL111676 for straightforward identification. Note: original units featured a long neck on the pulley - replacement pulleys do not include this neck. Verify your model and year against the fitment table before ordering.
