Product Number: 12031N
The WAI 12031N is a brand-new 24V 27A alternator. It is built to replace Bosch IR/EF original-equipment units across a wide range of heavy plant and construction machinery. It replaces Bosch original-equipment references including 0 120 400 640, 0 120 400 760, and 0 120 400 761 — part of a cross-reference list spanning 151 references including Delco Remy DRA0290 and DRA1260 — making it a reliable like-for-like solution for fleet and workshop procurement.
Designed to the IR/EF (internally regulated, externally fused) configuration, the 12031N delivers clockwise rotation and is supplied without pulley, allowing fitment with the machine's existing pulley assembly where the original is serviceable. At 24V and 27A output, it meets the electrical demands of the heavy-duty plant applications for which the original Bosch units were specified.
The 12031N fits equipment from Poclain (11 applications), ABG Allgemeine Baumaschinen Gesellschaft (4 applications), Atlas (3 applications), Liebherr (3 applications), Atlas Copco (2 applications), Case, and Fuchs — 25 confirmed applications in total. Representative fitments include the ABG Jumbo 140, Titan 350S, Titan 360, and Titan 410S, and the Atlas 2002, 2502, and 2502B.
