Product Number: 8709N
The WAI 8709N is a brand-new 24V 70A alternator. It is built to the Delco 24SI HP Series IR/IF design, replacing original-equipment units from Lucas (LRA03812), Cummins (3972735, 4936879, 4993343, 4993344, 5282841), Remy (8600017, 8600020, 8600154, 8600360, 8600407, 8600504, 8700019), JCB (333E5501, 714-40388, 714-40473, 714-40537, 71440388, 71440473, 71440537), and Prestolite Electric (MDA3946) — 21 cross-references in total. It is a direct-fit solution for operators needing a dependable charging unit for JCB wheeled loading shovels, including the JCB 434S and JCB 436E (2007–2012).
The 24SI HP Series internal-regulator/internal-fan (IR/IF) design means no external voltage regulator is required, simplifying installation and reducing potential failure points. At 24 volts and 70 amps, this unit delivers the output demanded by heavy-duty plant and construction machinery operating on 24-volt electrical systems.
As a brand-new unit rather than a remanufactured exchange, the 8709N carries no core-return obligation, giving fleet managers and independent engineers a clean, ready-to-fit replacement.
