I had a bad leak in the lift cylinder on my baby Fargo dump wagon.

My mechanic said he fix it if we could get it apart. Thing is huge and heavy. How to hold it after I drained the oil out of cylinder? This is what we came up with.

826 drawbar was just the right size to hold it from turning when we tried to unscrew the cylinder head.

Assemblies I salvaged years ago from Lundell and Gehl choppers were the right height to match the drawbar and get it up off the floor.

Unscrewing the head was an ordeal. Finally had to heat the barrel and use a 6' cheater bar on the 3/4 drive chain wrench to get the head off. The Farmall 400 drawbar anchored the rod to disassemble that.

When Dave gets the new seals, we get to repeat the process in reverse. I hope to use the wagon Saturday to open more fields. It fits down 3 rows behind the Fox without running down corn.
 
once we got the end unscrewed off the barrel, I pulled the rod out by hand, no problem. By then, the weight was down to where it was manageable.
 
I had a dump truck piston that I couldn't get apart easily. I was going to do something like what you did then decided a hydraulic shop that works on big stuff all the time should have the equipment and be able to do it easily enough. I sent it out. They cut the nut off threw it away, rebuilt the piston then machined a new nut(I had researched and knew the nut was N/A). Rather expensive. If I had known I would have done it myself!! Mine did not have a good solid eye like yours and I was bending the bracket, main reason I quit. But I could have done it had I known.
 
I don't want to push my luck.

On a related note, the usual place to get seals is in Florida, which seems to be otherwise occupied at the moment.
 
It's not always a DIY project. I did all three cylinders on my tractor and the two lift cylinders hold well but leak slightly. The bucket cylinder it didn't help at all. The cylinder must have had some scratches in it that should have been honed.
