Product Number: 6578N
The WAI 6578N is a brand-new 12-volt starter motor. It is built to the Delco 28MT OSGR design specification, cross-referenced against 17 OE and aftermarket references including Bosch USA SR10075X, Delco Remy DRZ5132, and Remy 10465349 — making it a dependable, like-for-like replacement for worn or failed original units.
Constructed to the 28MT OSGR (Over-running Starter and Generator Relay) configuration, this starter delivers clockwise rotation with a 10-tooth pinion gear, providing the engagement geometry the Delco 28MT design is known for. Supplied as a complete, ready-to-fit assembly, it requires no core return or rebuilding.
The 6578N covers 14 applications across Bobcat and Clark equipment, including the Bobcat 2000, 843, 843B, 843HC, 853, 853H, 943 and 974 skid-steer loaders, spanning model years from the early 1980s through the mid-1990s. Six Clark applications are also covered — use the selection widget or search the cross-referenced catalogue by machine model to confirm your specific variant.
