Product Number: 12586N
The WAI 12586N is a brand-new 24V 55A alternator. It is built to Bosch IR/EF specification, cross-referenced against 143 OE and aftermarket references including Bosch 0 120 469 001, Bosch 0 120 469 019, and Delco Remy DRA0520. It is a direct replacement for Bosch and Delco Remy original-equipment alternators fitted to a range of heavy-duty and agricultural applications, with confirmed fitment on the Valtra Valmet SK150 (1985–1992).
Constructed to IR/EF (Internal Regulator / External Fan) design, the 12586N delivers a regulated 55A output at 24V — a specification commonly required in commercial and agricultural machinery where robust electrical supply is essential. The groove pulley configuration ensures compatibility with the belt drive arrangements found on supported platforms.
Supplied brand new (not remanufactured or exchange), the 12586N is ready to fit straight from the box with no core return required.
