Product Number: 8003N-LD
The WAI 8003N-LD is a brand-new 24V 70A alternator. It is built to the Delco 21SI Series IR/EF specification, replacing the Powerite Automotive original-equipment reference 7642. It is designed for heavy-duty plant and agricultural equipment running 24-volt electrical systems, supplying a steady 70-amp output to keep batteries charged and ancillary systems operating under demanding working conditions.
The 21SI Series internal-regulator/external-field (IR/EF) design follows the Delco original layout, meaning the voltage regulation is handled within the unit itself — simplifying installation and ensuring compatibility with existing charge-system wiring. The alternator is supplied without a pulley, so the original pulley from the unit being replaced is retained and refitted during installation.
This unit has confirmed fitment across 21 applications including Samsung excavators (SE130, SE170, SE210, SE240, SE280 and SE350, 1992–1998), Timberjack forestry machines (6 applications) and Champion motor graders (710A and 716A, 1994–1998), as well as Volvo equipment (6 applications). A full application list is available via the selection widget.
