Product Number: 12744N
The WAI 12744N is a brand-new 24V 50A alternator. It is built to Mitsubishi IR (internal regulator) design, supplied as a direct replacement for original-equipment units across Hitachi excavators, John Deere machinery and New Holland Industrial equipment. It replaces Mitsubishi references including A004TU5485 and A004TU5486, and covers 28 applications across three makes.
Engineered for heavy-duty plant and agricultural use, this alternator features clockwise rotation and a groove pulley configuration. As a brand-new unit it arrives ready to fit without exchange or core charge, and the internal regulator design keeps the installation straightforward, with no separate regulator wiring to manage.
Fitment spans 19 Hitachi applications — including the EX120, Zaxis 200, Zaxis 250, Zaxis 330 and Zaxis 370 — alongside 8 John Deere machines and 1 New Holland Industrial application. Cross-references cover 13 OE and aftermarket numbers from Mitsubishi, Isuzu, John Deere, New Holland, AD Kuhner and Sando, making reverse-lookup straightforward when sourcing from a workshop invoice or service record.
