Hello all thanks for letting be here !
I have been weeding through searches and have not been able figure out my problem.
I have a 1968 JD 4010 with Koyker 310 loader.
Things I know
I had algae growing in the hydraulics when I bought it four months ago. The screen,filter and fluid is now clean.
The loader is weeping off. It floated down
I took the lift arm lines loose and blocked them off with plugs while the loader was in the air. The loader did not move for the two days it was this way. So the seals should be good in the lift arms ( I think)
I then reassembled and flipped the lines. Now with a 1200 lbs round bale the loader slowly lifts stil instead or floating due to the line reversal.To the point I have lower it quite often to use it.
I then took the spool valve apart that feeds the lift arms. The internals are metal on metal. I have a picture of the shaft. There is slight wear but no dirt and no gouges. Also it still has a real tight fit. I did not remove anymore lines or any other parts to the spool valve.
The rotation on the bucket does not bleed off as far as I can tell.
It seems something is not sealing off but I am not sure what.
Let me know any other information you need or pictures.
Thanks Mike
