Product Number: 12683N
The WAI 12683N is a brand-new 12V 120A alternator. It is built to Letrika (Iskra) IR/IF specification, designed to replace original-equipment units across 23 Valtra Valmet agricultural applications — including the 6400, 6550HI, 6750, 6850HI, A82, N101, N111, and N121 series. It is supplied without pulley, so your existing pulley assembly is retained during fitment.
Manufactured to Letrika's IR/IF (internal regulator / internal fan) design standard, the 12683N delivers a regulated 120-amp output suited to the demanding electrical loads of modern agricultural machinery. As a brand-new unit — not remanufactured — it carries no core charge and arrives ready to install.
This alternator cross-references 32 OE and aftermarket part numbers, covering Iskra, Letrika, Mahle, Agco, and AD Kühner references. Key numbers include Iskra 11204582, 11204583, IA0675, IA0925, AAK5850, and AAK5851; Mahle MG 177, MG 178, and MG178; Letrika 11.201.925, 11.203.017, and 11.203.099; and Agco 8366-660-39, 8366-662-26, and 8366-667-21 — among others in the full cross-reference set of 32.
