Product Number: 12091N
The WAI 12091N is a brand-new 12V 70A alternator. It is built to Lucas IR/EF specification, replacing original-equipment numbers across Ford, Lucas, Delco Remy, Iskra, Mahle, Remy, Magneti Marelli, and Massey Ferguson — with 28 cross-references in total. It is a direct-fit replacement for Ford agricultural and construction machinery, covering 38 applications across Ford (23), New Holland Industrial (14), and Massey Ferguson (1) platforms, including the Ford 3230, 3430, 3930, 345C, 345D, 445C, 445D, and 455D.
The unit ships without a pulley, so the original pulley is retained on installation. The IR/EF (internal regulator, external fan) design mirrors the Lucas factory configuration, maintaining correct charging characteristics on the original wiring loom without modification.
