Product Questions & Answers

Got an older Cessna hydraulic pump that's been weeping fluid around the shaft for a while now. This part number, 15511-85, that's gonna be the right seal to fix that up?

Question by: Patty P on Mar 22, 2026, 4:31 PM

For Danfoss and Cessna hydraulic pump and motor assemblies, that part number is the correct shaft seal to address leakage at the rotating shaft interface. It's built to Danfoss hydraulic standards and listed as a direct replacement or service part for those systems. The 1.13 inch width is the key dimensional detail to verify against your existing seal before ordering, just to make sure the fit lines up with your specific pump configuration.
