D10 Hydraulic Valves

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   It has been a while, been delayed with other life things but I am back on the D10.
I tore the back down to all but the bull gear being removed, replaced brakes, seals, changed the oil in the final drive reservoirs, had lift cylinders rebuilt, replaced all hydraulic lines and replaced filter and fluid. I also put o rings in the pin box controls.

I started the tractor up a few minutes ago and found 2 things. The PTO arms lift slowly on their own and I am still getting fluid out of the back weep hole of the main lift controller. I was able to locate all of the factory orings except the main one on the valve, discontinued. It looks like I can service the valve on the tractor, does anyone have a source for the correct o rings for the valve and why is my PTO lifting on its own? Related issue??
