A direct-fit replacement 12V 70A alternator for the John Deere 4120, 4320, 4520, 4720, 5225, 5325, 5425, and 5525 tractor range, and a number of John Deere skid steer 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 6-groove pulley, cross-referencing John Deere OEM part number SE501831 for straightforward identification. Verify your model and year against the fitment table before ordering.
