Product Questions & Answers

Got an Eaton piston pump that needs a servo piston swapped out. This the part I'm looking for, part number 113686-001?

That's the one. SKU 113686-001 matches the Danfoss/Eaton supplier part number exactly, and it comes packaged as a complete servo piston subassembly ready to drop in. It's sourced straight from the Danfoss/Eaton supply chain, so you're getting a genuine replacement, not an aftermarket substitute. Built for Eaton and Char-Lynn piston pump assemblies where the servo piston handles displacement control.
