Product Number: 7850N
The WAI 7850N is a brand-new 12V 100A alternator. It is built to the Delco 27SI/200 Series IR/EF specification, replacing original-equipment numbers from Cummins, Remy, Caterpillar, AC Delco, and Eagle across agricultural and industrial applications. Fitment data records one Caterpillar Ag. & Ind. application, including the Caterpillar 65 Challenger (1986–1997).
Built to the proven 27SI/200 Series internal-regulator/external-fan design, the 7850N delivers 100 amps at 12 volts with bidirectional rotation — allowing correct installation regardless of belt-drive orientation. It is supplied without a pulley, so the original pulley is transferred from the unit being replaced, preserving correct belt geometry and eliminating unnecessary component spend.
As a brand-new unit rather than a remanufactured exchange, there are no core-return obligations and no concern over prior wear history. Cross-referenced OE numbers include Cummins 3604659RX, Remy 10459238, Remy 1100091, Remy 1101287, Remy 1105472, Remy 1105473, Remy 53126, Remy 93055, AC Delco 321743, Caterpillar 0R2793, Caterpillar 9W1082, and Eagle 7138AD — 12 references in total.
