Product Number: 12310N
The WAI 12310N is a brand-new 24V 40A alternator. It is built to the Mitsubishi IR/EF design, replacing original-equipment numbers from Mitsubishi, Delco Remy, and Case across a range of heavy plant and agricultural machinery. It is a direct-fit replacement for applications including the Case 9050, Caterpillar Ag. & Ind. DP100 and DP115, and Mitsubishi 6D2 — four verified applications in total across three makes.
Constructed to match the output and rotation characteristics of the original unit, the 12310N delivers a clockwise-rotating, 40-amp charge at 24 volts, making it suited to the higher-voltage electrical systems found in larger plant and agricultural equipment. The Mitsubishi IR/EF design is a well-established architecture in this power class, and WAI's replacement is supplied brand new — not remanufactured.
Fitment is cross-referenced against Mitsubishi OE numbers including A4T40286, A4T40287, A4T40289, and A4T40299, as well as Delco Remy DRA0398 and Case 135104A1, among 14 verified references in total.
