Product Number: 8077N
The WAI 8077N is a brand-new 12V 51A alternator. It is built to the Motorola IR/EF design, supplied without pulley and intended as a direct replacement for original-equipment units across a range of industrial and plant applications. It is cross-referenced against Bosch USA AL9937X, Caterpillar 0R3654 and 6T1396, Prestolite 110-284, 110-312 and 110284, and a further 10 verified OE references — 16 in total — making it a well-validated aftermarket choice for fleet and workshop buyers.
The alternator operates at 12 volts with a 51-amp output and supports bi-directional rotation, giving flexibility where the mounting orientation or drive arrangement differs between applications. The IR/EF (internal regulator / external fan) configuration is consistent with the original Motorola design it replicates, and the unit is supplied brand new rather than as a remanufactured or exchange part.
Fitment data confirms compatibility with the Sullair 375 compressor (1985–1991), and the part carries 16 OE cross-references spanning Bosch, Caterpillar, Prestolite, Motorola, CAT, and Sando — use the cross-reference catalogue or selection widget to confirm fit for your specific machine.
