looking fro some info on what type of Hydraulics I have on my M and what could be wrong with them. I am going to attach some photographs
This is my wifes late grandfathers M tractor. I picked it up a couple years ago and have been working on it to get it up to par.
Runs like a champ but I have hydro issues. When It has two remotes and appears with the modification to be a live-hydro system. Can find anything on the pump near distrbutor so i dont know make or model.
I changed the in-line filter- filled to proper level with hi-trans fluid and hooked up to a two-way cylinder. it operates the cylinder by its self but it surges as it operates. I then put the cylinder on a mower and it surges and will not extend all the way. it will extend but then gets to a point where it stops then will start going down.
When I removed the lines one is full of fluid and the other has air in it. So
I pulled out a single way cylinder and it operates the same way. Surges but will work fully off the mower but on the mower it will surge while it raises then get to a point where it will stop then start to fall while trying to raise the mower.
When I have connected hoses and again checked fluids i have noticed that the fluid is full of air bubbles and looks milky with the bubbles in it.
Where do i go from here? is the pump bad? getting air in the system some where? wrong cylinder? Also The bleeder valve will leak some while trying to operate the hydro and after the tractor is shut down it will hiss/ purge air. I see that that brass nut on top of that valve can be tightened and closed. Should it be closed?
