Find the right Starter Motor & Alternator for your Machine
Starter Motor & Alternator FinderThe WAI 12381N is a brand-new 12V 150A alternator. It is built to Bosch IR/IF design specification, replacing original-equipment Bosch units including 0 123 515 500, 0 123 515 501 and 0 123 515 503, as well as Delco Remy DRA4213. With 89 cross-references spanning Bosch, Delco Remy, Iskra/Letrika, Mahle and Letrika, this unit covers a substantial portion of the agricultural alternator market in a single part number.
Constructed to internal regulator / internal fan (IR/IF) design, the 12381N delivers a 150-amp output at 12 volts — a robust charging capacity suited to the electrical demands of modern agricultural machinery. Clockwise rotation and a groove pulley configuration match the drive arrangements found on the original fitments it replaces. Being supplied brand new, it requires no core exchange and carries no exchange surcharge.
Fitment spans 26 applications across John Deere (15 applications), Deutz-Fahr (6 applications), Massey Ferguson (3 applications), Lamborghini-Agricultural and Valtra Valmet. Confirmed models include the John Deere 6120 and 6220 (2002–2005) and the Deutz-Fahr 5100, 5100 TTV, 5110, 5120, 5130 and Agrotron (2007–2013).
