Product Number: 14391N
Variations
The WAI 14391N is a brand-new 12V 55A alternator. It is built to Bosch IR/EF specification, replacing original-equipment Bosch units across 9 applications covering Mercedes Trac agricultural tractors, the Komatsu D30E crawler, and Schluter machinery. With 119 OE cross-references on file — including Bosch 0 120 489 032, 0 120 489 725, and 0 120 489 726 — it is the straightforward like-for-like replacement for worn or failed Bosch charging units on these vehicles.
The alternator is supplied brand new (not a remanufactured exchange unit) and is designed for clockwise rotation. It is supplied without a pulley, so the original pulley from the outgoing unit must be transferred at fitting — a standard workshop procedure on this type. The IR/EF (Internal Regulator / External Fan) design matches the original Bosch configuration, ensuring direct compatibility with the vehicle's charging circuit without wiring or bracket modifications.
With 119 cross-references in the WAI catalogue, this unit covers a broad spread of Bosch part numbers including exchange references such as Bosch Exchange 0986030190 and 0986034260.
