I have a B8200 with hydrologic lift issues.
Bought the tractor a few years ago. Just now getting it ready to work.
* When I bought it the hydraulics did not work. System was dry.
* I replaced the inline filter put fresh hydraulic fluid in it.
* System worked at first, but the pump leaked at the shaft seal.
* Pulled the pump, replaced all the o rings and the shaft seal.
* Put it back on and lift only worked a short time. Pump was hot!
* Pulled the filter again. It was clogged l. So I cleaned it, and put it back together.
* Added diesel to the system rocked the tractor in an attempt to clean out the system.
* Drained it again, cleaned the filter, strained the diesel back into the tractor, aggatated the tractor again, drained it and cleaned the filter.
* Note: I did not run the tractor with the file in the system.
* Added fresh hydraulic fluid again.
* Now it makes what I'd call a groaning sound. When it groans the lift will go up about an Inch or 2. Stops for 10 sec. Groan up a bit. Stops groan, up an inch or 2. Till it's all the way up. Goes down fine.
* Groaning sound seems like it might be coming from what I think it a valve located just behind my left ankle.
* I have 2x caps to add hydraulic fluid. Small one in front behind the shifter. One bigger back a bit under the seat.
There is a dip stick next to the front fill cap. I'm filling the system in the back cap, but using the dip stick to fill the system.

I have to assume that spell correction is not helping and you really mean “hydraulic problems”!

Since you have stated it was a dirty sump and that you have cleaned it up some, I would suggest that you need to see if there is good flow through the system. I am assuming that the internal surfaces of the tubes and hoses may be dirty or rusted and blocking flow. Does the engine seem to be under a load when trying to operate the FEL upwards? I assume that is the “groaning“ sound you described.

So starting at the pump outlet pipe, see if you can disconnect it at the terminal point and route it to a clean bucket or back to one of the fill ports. Then start tractor and see if you have good flow. You can start at the FEL valve power in line or power beyond line also.

I don't think he has a Front End Loader I think he just has the three point lift.

There sounds to be some blockage in the relief valve valve and cylinder ports.
