This subject should be over by now. However my experience. I abused my hydrolic pump and had to replace it.
I bought a pump online and after the installation, could run the engine for less than five minutes and hydrolic oil blew out of ever surface possible.
I tore the engine apart 3 times looking for a crack in the head and other problems.
My buddy Eddy looked at the problem and said a part (not the impeller) was installed backwards on the manufacturing floor. We dismantled the pump and reversed a gear and the hydrolic oil flowed outward instead of inward.
Eddie’s Pa-Pa stepped in and informed me with the impeller moving in the wrong direction the hydrolic pressure could not leave the cylinder block, with 3500 pounds of pressure coming from the pump. NO wondering anymore. Problem solved.

I very much believe the tractor needs new fluid. So with loss of viscosity, age, dirt work and dirty foamy fluids. I think it does not matter what type of fluid I used… The question would not be, what would be the replacement fluid. (See what I mean)… Right now, nothing but trouble and zombies are in the mechanical devices. I have assessed that all the main pumps… are working. There is an adventure going on, the tractor is in Buchannan, Virginia, as I had an accident on 581. Those guys working in the garage are all tractor boys and one guy told me he would clean and flush and put in fluid that will not foam. Like the Dextron with an -F or something else modern day trucks use. We shall see…. Still need to know what you recommend. L.
And lastly… I think this little red tractor overheats way to fast. Bush Hogs last only 20 minutes with a 5 foot chopper. Then it overheats.
Why.. because my oil is out of balance.. bad… and cant take the stress…
Plus for how much I like this Jinma… I don't know what to think about that radiator. It does not leek, but alway… clogged or bent, or smashed.
I would like to believe the reason the engine overheats is because of the hydrological oil between implement and engine.
What say thee to that… L.

I would like to agree, but it was the hose the snapped and broke. The hose junction was saved by a skilled electric motor guy in Martinsburg, WV. Some kind of funny size…
so how do I test the pump… if it has pressure or is clogged up.
And you know that gizmo box UP DOWN LEFT RIGHT front end loader. Well that works no more. some times I get enough hydrolic to move it up and down. and as for the 3 point hitch. it went into retirement. There is nothing there..
The grand question is … dirt in line, bad oil, or pump kabosh….
What say thee.
