Some cylinder glands have a screw at the seam of the gland to barrel and maybe its broken off to where you cant see it. If so drill it out.
Or maybe your Case cyl doesn't have that. If no keeper of any kind I would try some heat from your torch at the thread area of the barrel. I wouldn't turn it red though. This should not hurt anything. Sounds like the seals are already shot.
Sometimes they are difficult.

and as mentioned they can be veeery tight
2/4 indents find some heavy wall pipe slightly larger weld some matching tabs about 1" up inside file to a snug fit
tack a plate on top of those. double plate the top with a nice 3/4 drive hole
leave cyl attached to machine/other large device.heat use 4' breaker/air gun if you trust the weld
all manner of axle hub nut tools are similar 4 x 4 etc.

MMI I have that very tool. Unfortunatly I have the cylinder rod and knuckle on that end of the cylinder. Rawleig99 has a good idea about welding a wrench to the cap and beat the rust out of it. If it looks too bad I will take it to the hydraulic shop. I took a harrow tooth and ground it a bit and got a few good licks in with a hammer untill it layed over the end. I ground an old chisel to fit the hole but the protrusion split off from the chisel. I think I am smarter than a fifth grader and I hope that I am smarter than rust.
?? retract the rod , make the pipe a little longer? , (no drawing function on here? ) I keep thinking socket head with handles like commercial pipe threader??
hydraulic shops here charge 95-150% of new on repairs.
5t floor jack (they have the wrench) $700 to rebuild + parts new $655

The tight glands on the cylinders had had set screws in them when new but the cylinders have been rebuilt and the backhoe repainted. The glands were tightened more than 1/4 inch past the set screws that were put in at the factory. No wonder they are tight. I plan to weld my homemaid tool to the gland to take it apart. I think I will put the pins in the holes and tack weld the wrench on. When I get the gland off I will redrill the holes oversize to clean up the holes.
