Product Number: 12373N
The WAI 12373N is a brand-new 12V 120A alternator. It is built to Bosch IR/EF specification, replacing original-equipment units across a broad range of John Deere, Case, Apache, New Holland Industrial, and Willmar agricultural and plant machinery. With 21 verified OE cross-references spanning Bosch, Case, Iskra, Mahle Original, John Deere, and New Holland, it slots in as a direct replacement for worn or failed charging units on 63 recorded applications in total.
Constructed to Bosch IR/EF (internal regulator/external fan) design, the unit delivers a rated 120 amperes at 12 volts with clockwise rotation — matching the output profile of the original fitment. It is supplied without a pulley, so the existing pulley from the original unit is retained during installation. Being brand new rather than remanufactured means there are no worn bearings, rebuilt stators, or reconditioned regulators to introduce reliability risk from the outset.
The fitment spread covers John Deere (47 applications), Case (10 applications) including the 3150 Patriot, 3185 Patriot, 8825, SPX2130, SPX3150 Patriot, SPX3185 Patriot, and SPX3200, as well as Apache (including the 859), New Holland Industrial (2 applications), and Willmar (2 applications).
