Product Number: 12029N
The WAI 12029N is a brand-new 12V 33A alternator. It is built to the Marelli IR/EF design, replacing Bosch original-equipment units including 0 120 300 527, 0 120 300 528, 0 120 300 529 and 109 cross-referenced numbers in total. It is a direct-fit replacement for agricultural and industrial machinery across Lamborghini-Agricultural, Hesston, Same, Fiat-Hesston, New Holland Industrial and Ford applications — 167 verified fitments in all.
Constructed to match the original specification, the 12029N delivers clockwise rotation and is fitted with a groove pulley, making it a like-for-like swap for the worn or failed unit on your machine. The IR/EF (internal regulator, external fan) design keeps the electrical architecture straightforward, and the brand-new condition means no refurbishment unknowns.
With 47 Lamborghini-Agricultural fitments, 42 Hesston, 36 Same and 32 Fiat-Hesston applications among others, this alternator covers a wide spread of mid-range agricultural tractors from the mid-1980s through to the 1990s and beyond — including Fiat-Hesston models such as the 45.66, 55.46, 55.56, 55.65, 55.66, 55.75, 55.85 and 55.86.
