Inspired by Winston's Hydro oring replacement i decided to finially do mine. I have been thinking of doing it for over a year or more. When i bought the parts for my rear wheel seal, i bought the necessary orings for it as well. Since i had the tractor at the house i deceided to do it as well. I pulled the Hydro top off. It must weigh close to 80lbs!! It would have been way easier to pull the ROPS off to stand behind the tractor vs standing on top of the trator floor boards in reverse and manhandeling in upwards then resting it on the toolbox/ROPS then getting off and carrying over to a table.
Once off i took the back off the lift then took the front off the lift, then pressed the piston out with a long screwdriver. The front of cylinder was hard to get off. I think the o-ring on the cyl head kid of seized itself in or either the top seized to the main body. It took several good whacks with a chisel to the head then plenty of whacks of a deadblow hammer to get it to move, then i was able to pyr it off with a screwdriver and pull it the rest of the way out. But for you to pull the piston out the front you would have to do the same thing i did, but you could do it without removing the hydro top totally. BUT mine was not sealed well and was leaking so i wanted to remove it and seal it up good. This allowed me to kill 2 birds at once. I also put a new o ring under the 3pt control valve, and then put 2 on the holes that i guess control the fluid flow to the piston, that are under the cyl head.
Have yet to start the tractor up, as im waiting for the silicone to dry.
But again can i say i hate whatever the refurbers use to "glue" gaskets on!! You can barely scrape it with a razor blade. I resulted to a wire wheel to "wear" it away and "eat" it down to the metal. I mean the stuff is tough. They use some paper gasket stuff and some glue that looks greyish, but is not silicone like but kind of glue like i guess. It forms very good bonds in the joints, and the paper basically tears apart leaving some on each side.
