If its anything like my 863, they have O-rings and I think plastic clip on top . One on left one on right. Let me find a picture and attach it. It was a simple fix. I did buy oem parts from bobcat. It should be (if we are talking same thing) where the left and right Forward sticks connecting too.
FYI the Schematic picture is on it's side...NOT up and down in the machine...not sure why they show Hydr like that.
