Product Number: 7975N
The WAI 7975N is a brand-new 24V 75A alternator. It is built to the Delco 30SI Series IR/EF design, replacing original-equipment units from Cummins (3056492, 3675103RX, 4016557), Remy (1117805, 1117821, 1117831 and more), and Caterpillar (1142401, OR8997), among a total of 15 OE cross-references. It is suited to demanding plant and agricultural applications where a reliable charging output is essential.
Constructed to match the 30SI Series IR (internally regulated) / EF (externally fan-cooled) configuration, the 7975N features bi-directional rotation, making it compatible with both clockwise and anticlockwise drive arrangements without modification. It is supplied without a pulley, allowing fitment with the original pulley from the unit being replaced.
The 7975N covers 16 recorded applications across Champion and Caterpillar Ag. & Ind. equipment, including the Caterpillar 517, 527, and AP650C and Champion 710, 720, and 720A series machines. With brand-new construction throughout, it offers a dependable alternative to a reconditioned or second-hand unit.
