[Vwdiesel] OT: Case 580B CK hydraulic question

[Travis Gottschalk]

I am guessing the valves as well. Dead heading another cylinder group building the pressure to bypass in the valve group causing it to back feed to your swing function and only one side at that. Might require a couple seal kits and/or bypass valves. At the mine we saw some interesting things happen as well but it typically came down to those two items. Just finding where is the issue. I am guessing though your cylinders don't have much of a part in this issue.
