Product Number: 18281N
The WAI 18281N is a brand-new 24V 3.5kW starter motor. It is built to Hitachi OSGR specification, replacing original-equipment numbers including Hitachi S24-07, S2407, S25-121 and S25-121A across Isuzu industrial equipment and TCM forklift applications. With 11 OE cross-references on file — spanning Hitachi, Isuzu, Delphi, DRI and Unipoint — this unit is well-documented for buyers sourcing a direct OE replacement.
Designed to the OSGR (Off-Set Gear Reduction) architecture, the 18281N delivers reliable cranking performance where heavy-duty 24V starting is required. Clockwise rotation and a 9-tooth pinion match the geometry of the original Hitachi units it replaces, ensuring correct engagement with the ring gear without modification.
Fitment covers Isuzu miscellaneous industrial equipment (1995–2000) and TCM Equipment models FD23Z and FD25Z (1978–1997) — three confirmed applications across two equipment brands. Cross-referenced Isuzu OE numbers include 5811001290, 5811001291, 5811001292 and 8944234520.
Supplied brand new, not remanufactured.
