Product Number: 12140N
The WAI 12140N is a brand-new 12V 55A Magneton alternator. It comes with an IR/EF (internal regulator, external fan) design, replacing the original Prestolite Electric unit 20110293 and John Deere OE references RE500502, RE57960, and RE57961. It is a direct-fit replacement for agricultural and construction machines across John Deere, Dynapac, Compac Equipment Mfg., Ingersoll Rand, and Atlas Copco equipment — covering 28 applications in total.
Built to Magneton's original specification, the 12140N delivers a clockwise-rotation output with a groove pulley drive, matching the geometry and electrical interface of the factory unit. The IR/EF configuration integrates the voltage regulator within the alternator body, simplifying installation and reducing external wiring requirements. Supplied brand new, not remanufactured.
The alternator also corresponds to Magneton part numbers 9-515-762, 9-515-765, and 9-516-762, as well as Pal Magnaton references 9515762, 9515765, and 9516762 — a total of 10 cross-referenced OE numbers, making identification straightforward for workshop and fleet buyers working across multiple machine brands.
