Eaton Hydraulic Pump Woodruff Key

Eaton Hydraulic Pump Woodruff Key

This genuine Eaton/Danfoss woodruff key is an essential drive component for heavy-duty hydrostatic systems. It is specifically designed to fit 1-3/8-inch tapered input and output shafts on Eaton Series 33 through 76 pumps and motors, including the popular 5423 and 6423 series. In concrete transit mixers, this key locks the 1310 or 1350 series driveline end yoke to the main hydraulic pump shaft, ensuring reliable power transmission from the PTO to the mixer drum. Replacing a worn or sheared woodruff key is critical to prevent shaft damage and maintain proper hydraulic drive function.
