Find the right Starter Motor & Alternator for your Machine
Starter Motor & Alternator FinderThe WAI 21351N is a brand-new 12V 150A alternator manufactured by Letrika to the Iskra IR/IF internal regulator design. It is a direct replacement for original-equipment units supplied by Bosch, MAN, Iskra, Mahle, Fendt, Letrika, DAF, KHD, and SAME across a wide range of commercial vehicle, plant, and agricultural applications — 20 verified OE cross-references in total.
Built to the Iskra IR/IF specification, the 21351N delivers a robust 150-amp output at 12 volts with clockwise rotation. The integrated internal regulator (IR) and internal fan (IF) design means the unit arrives ready to fit as a complete assembly, with no separate regulator or ancillary components required. As a WAI brand-new unit — not a remanufactured or reconditioned part — it carries none of the wear history associated with exchange alternators.
With cross-references spanning Bosch 0 123 510 060, MAN 51-26101-7221 and 51-26101-7251, Mahle MG 3, Fendt G 515 900 010 100, and multiple Letrika and Iskra part numbers, the 21351N covers a broad spread of heavy-duty equipment originally fitted with this alternator family.
