Eaton Fuller 4300247 Countershaft Gear — Position Varies by Model

Product Overview

Genuine Eaton Fuller 4300247 countershaft gear used in supported manual transmissions. Eaton model catalogs can assign this gear to a specific speed position, including a third-speed countershaft position in one verified model group, but the position is not universal across all transmissions.

Application and Service Notes

Do not publish or select a speed position without the model-specific illustrated parts list.

Please confirm 4300247, the transmission identification tag, exact countershaft position, physical teeth, mating gear, matched quantity, ratio, and serial range before ordering.
