806 Farmall remote hydraulic problems

When I opened my tailgate on baler, it would not close. When I moved my remote lever, hydraulics load up and nothing happens. I changed all male and female couplers. Front end loader will not work either, it loads up and only jumps a little.
 
Don't know an 806 very well, it its sounds like all your hydraulics are inop. That would lead me to look for a pressure relief somewhere on the tractor hydraulics.

Just a guess.

Reading your description of the problem, I assume you mean the hydraulic system builds pressure. First test is with engine not running. Does lever stay in detent position in both directions. If not, you need to correct that first, linkage to valve or problem in valve. If it does latch ok, start engine. If it kicks lever back to neutral you then know fluid is restricted some where between valve and cylinder. As you said you changed couplers, (which is normally the problem) I would look to see if you have a check valve block in the system and suspect that. When problems like this develop it is often best to just eliminate all couplers and hook hose directly together to determine where the problem lies. Now if the levers just stay in detent when you start engine you have a lack of flow and pressure from pump, relief valve or blown O-rings on pump mount.
 
It sounds like you are getting pressure to one direction only. I have had that problem some times when you use the pioneer ball coupler against the IH coupler with the points. I just changed to either the balls or stayed with the points. The balls will sometimes cause the point to shift sideways letting the ball stay closed. Otherwise the valve may have worn to the point the oil is going by the spool. After all the tractor is 40 years old. The decent shouldn't have anything to do with the pressure problem you have. We took the detents out of our valves with no problems.
