Product Number: 12781N
The WAI 12781N is a brand-new 12V 120A alternator. It is built to Bosch IR/IF specification, replacing Bosch original-equipment references 0 124 515 126 and 0124515126 as well as Delco Remy DRA0838 and a range of Iskra and John Deere OE numbers. It is designed for fitment across nine John Deere applications, covering Premium and standard models in the 6000 and 7000 Series from the 2007–2012 model years.
Constructed to internal-regulator, internally-fused (IR/IF) design, the alternator delivers 120 amperes at 12 volts with clockwise rotation. It is supplied without a pulley, so the original pulley from the outgoing unit is transferred at installation. Being brand new — not remanufactured — it carries none of the wear history of a rebuilt unit, giving confidence in service life from day one.
With 13 cross-referenced OE part numbers on record, this alternator spans Bosch, Delco Remy, Iskra, John Deere, and DRI original equipment, making reverse-lookup straightforward for workshops sourcing by the original number.
