Product Number: 12131N
The WAI 12131N is a brand-new 12V alternator. It is designed as a direct replacement for the original Bosch unit, cross-referenced to Bosch OE number 0 120 468 028. It is built to restore charging system performance on Case agricultural machinery and a small number of International applications, covering 68 verified fitments in total.
Engineered to OE specification, this alternator delivers the same 12-volt output as the factory-fitted Bosch unit it replaces, making it a reliable like-for-like substitute when the original charging component has failed or reached the end of its service life. WAI is a well-established manufacturer of rotating electrics, and this unit is supplied brand new — not reconditioned or remanufactured.
The WAI 12131N is confirmed to fit a wide range of Case combine harvesters, including the 1420, 1440, 1460, 1470, 1480, 1620, 1640, and 1644 across model years spanning 1981 to 1995, plus one International application. Always verify against your machine's existing alternator or use the selection widget to confirm fitment before ordering.
