Is there an o ring or seal of some kind in there? how hard is it to replace? Thanks! [Reply]   [No Email]

Tore everything apart, none of the o rings were right. So I had to go back to JD and get the correct o rings. This is MY fault though, I forgot to tell you that the hydraulic outlets are not John Deere, they are Pioneer. [Reply]  [No Email]

My having spent many,many hours behind a JD parts counter probably gives me a small edge over you in looking up JD parts. Granted sometimes I can't find what I'm looking for either.

I tried to find that picture myself at the JD parts website, but I just couldn't find it. Don't feel bad, most of my questions are hard to comprehend! [Reply]  [No Email]

It doesn"t seem to be leaking there, it seems like its leaking from rear of that. I think some people call it a hydraulic block? If you put your hand on the back of it, then push your hose in, there is something that slides out in the back, thats where its leaking [Reply]  [No Email]

They are a common leak, on these valves, I have come up with a Quad ring style seal with 2 lips on each ring and a solid back up ring to go with it that seems to be working out good. I'll try to get some pics of them and the fancy tool I made to seat them with posted tomorrow. I have been using them for a few months now, I also came up with the same style for the handle seal too.
