DANFOSS / EATON DR GR S/A STR

Packaged as a complete drive gear subassembly, this unit handles the accessory drive function on compatible Danfoss and Eaton piston pumps. The part number is 26012-217, and what ships is the DR GR S/A STR assembly itself. It's the mechanical interface that allows auxiliary or accessory functions to be driven off the main pump, which is a pretty common setup in mobile and industrial hydraulic systems.

This accessory drive gear is designed for Danfoss / Eaton piston pumps, and it's available in all configurations and sizes, so it should be a suitable replacement as long as the part number matches.
