Product Number: 12151N
The WAI 12151N is a brand-new 12V 95A alternator. It is built to Bosch IR/EF specification, replacing Bosch original-equipment references including 0 120 484 020, 0120484020, and 0 120 484 002, as well as Delco Remy and Iskra / Letrika units across 69 cross-referenced part numbers. It is designed to fit 59 John Deere applications, covering models such as the 1068, 1075, 1550, 1750, 1750V, 1850, 1850F, and 1850V.
The alternator operates at 12 volts with a rated output of 95 amps and turns clockwise (CW). The IR/EF design — internally regulated, externally fan-cooled — is the standard Bosch architecture used across a wide range of John Deere agricultural machinery from this period, making the 12151N a direct, like-for-like replacement without wiring or bracket modification.
Supplied brand new (not remanufactured or exchange), this unit carries no core charge and requires no return of a worn original. The WAI part number cross-references directly against the Bosch, Delco Remy, and Iskra / Letrika families listed in the OE data, so buyers can verify fit against the number stamped on their existing unit.
