I am working on the power steering on our 2840. I'm looking for a little advise from the other poor individuals that have had to deal with these lemon tractors. So the unit gets much hotter than other hyd components which points to internal leakage along with a hesitation or click of sorts when the steering is turned. It only does that when the tractor is running-nothing with tractor off and manually turning the steering. A few times the steering has gone fully to the left on its own, but not very often(this is not very handy when mowing road ditches). No external leakeage other than just recently the side cover with the bushing for the pitman shaft started to seep. Hoping new seals in the bottom piston will fix that.
So is my thinking correct that one of the two valves in the column could be causing this? Or could this all be from one of the 6 internal o-rings leaking? Two of the six orings were darker in color than the others, I assume from getting hot with the bypassing oil. I have a tech manual ordered but hasn't arrived yet. Was going to wait until I had the manual our hay is withering away due to this drought and am going to have to get it cut very soon. Sorry for the long post & Thanks in advance. Adam
