you can use a come along from end to end... or set one end of the cylinder against the wall or tree, and push on the other end with tractor, etc... take the hose off.
or you can pump oil or air into the VENT hole and push the piston back to the bottom.

Ok I thought I broke something or there was air in the cylinder.
How can I compress the cylinder so I can put it on the tractor |

With the new o ring the cylinder no longer leaks.
But now it won't extend or retract once I put it back together |

If you replaced the piston seals, and didn't remove the piston from the rod to replace the oring, it could be leaking by the rod threw the hole in the piston. That may have been the problem to begin with?

I'm going to get a o ring to see if that's what's causing the leak

--you could plug the vent.. but then the boom might stay in one position... or barely work
--you could install a SPARE cylinder if you have a good one ( air test for leaks) --you could put a 3/8 hose in place of the "vent" and run the hose back to the hydraulic case fill plug.

Looks like you've got a problem with the leaker. If it leaked before, either there's a problem that wasn't addressed or the new seals aren't working for some reason. It probably isn't going to fix itself.

The piston should be sealed to the rod with something, like an Oring. The other cylinder doesn't leak ??

Now that I think about it there was no o ring on the shaft under the piston. Could that be the problem

You never said if it was an allis loader or not allis loaders made by freeman don't have a vent or even a piston in them they'd displacement cylinders with just chevron seals around the shaft. The very small plug is a bleeder port and requires a seal on it.

I just ment if he had a couple used cylinders he could TEST them before he installed.. Have an idea if they are any good or not..
If you have a minor leak, you could removed the VENT and connect a small 3/8 hose or so and run it back to the oil tank ( transmission fill plug or ??) ..... then any "leak by" would go back to storage and not on the ground... Not a "FIX", but if you dont want to spend any more time or money right now, it would be usable.

So, you have a piston and the seals run inside and SEAL against the barrel inside wall. Bad rough barrels or cut seals is why they would leak oil. Don't worry about air, worry about oil leakage.

So if air is still leaking when fully extended the seals are bad?
And the cylinders have hockey puck looking things at the bottom where the seals go |

Many one-way cylinders on old loaders never even had a piston in them. The V-packing seals are in the head of the barrel and just seal around the rod. So, which kind of cylinder is it ??? Does it have a piston?? Or just "V"-packing around the rod at the end of the barrel ???

you can put 100 psi air into the oil port of an old cylinder.... let it move the rod all the way open... and then check the VENT PLUG and see if air is leaking out.... That tells you the condition of the piston seals...... cylinder should not be dry... If it has a little OLD OIL that is fine... If it is completely dry, you should pour a couple spoons full of oil in the hole first.

if there is oil on the EMPTY end of the cylinder... then it is leaking past the PISTON PACKING... Either the seal / o-ring/ wiper was damaged during install, or the inside of the cylinder is pitted / corroded and caused the new seals to leak.
