Product Number: 12311N
The WAI 12311N is a brand-new 12V 50A alternator. It is built to Mitsubishi IR/IF specification, replacing original-equipment numbers including Mitsubishi A002TA2871, A002TA2871A, A2TA2871, and a further five Mitsubishi references. It also cross-references to Bosch USA AL10081X and AL5056X, Delco Remy DRA0868, and Remy 50875 — 13 OE references in total. Designed for demanding industrial and agricultural lift-truck applications, it fits Caterpillar Ag. & Ind. and Clark machines across 17 confirmed applications.
The 12311N delivers 50 amps of charging output from a clockwise-rotating design with a groove pulley, making it a direct-fit replacement for the internal regulator / internal fan (IR/IF) configuration used across these platforms. As a brand-new unit rather than a remanufactured exchange, there are no core charges and no worn internals to consider — simply fit and operate.
Confirmed Clark and Caterpillar Ag. & Ind. applications include the Caterpillar GC15, GC18, GC20, GC25, GC30, GP15, GP18, and GP20 models (1992–1997 build ranges), alongside seven Clark applications. Use the selection widget or search by OE number to verify fit against your specific machine and engine variant.
