Part Numbers

Product Description

The ATG10681 Alternator is an aftermarket replacement alternator designed for selected Isuzu industrial engine applications. Operating on a 24V electrical system, this alternator delivers 40 amps of charging output to help supply electrical power and maintain battery charge in compatible heavy-duty equipment.

This alternator features an internal regulator (IR), an external fan (EF), clockwise rotation, and a V2 pulley class. The supplied specifications identify a two-groove V-belt pulley with an approximate outside diameter of 82 mm. These details are important when matching the replacement unit to the original alternator. Always verify the pulley dimensions, mounting configuration, electrical connections, and regulator setup before installation.

The ATG10681 cross-references Isuzu 1812003970, Arrowhead 400-50022 and NK0-35000-3370, Nikko 0-35000-3370, Lester 12264, J&N 400-50022, and WAI 12264N. Listed applications include selected Isuzu 6BD1T industrial engines and Link-Belt LS4300 excavators with an Isuzu 6SD1 engine. Because the supplied application data includes different engine designations, confirm the exact equipment model and original alternator part number before ordering.
