Did you properly support the underside like I suggested?

Did you ever get these pins out? How did the repack go? My swing cylinders are looking more and more like they need a repack... might be a good winter task.

Just back from trip to Europe for work, next step it to cut 'em with the angle grinder, then remove cylindar, order all stuff for repack and new pins. I will get my kid to phoro to spark spray. Work and Christmas and the cold are obsticles as great as the stuckness of the pins, but I shall prevail!!!!

I have had pretty good luck using an air chisel to knock things like pins out. I cut the end off of one of the chisels so I had a flat end to drive with. The vibration will loosen rust and you don't put nearly as much strain on things as you do when whacking with a big hammer.
It also helps if you can put something under the fitting to hold it solid while tapping away. If you are trying to drove the pin out with no support under the arms the arms are absorbing most of the force and you can bend them. I usually use a deep socket that is larger than the pin under the arms so the pin can slide into the socket.
I hope that makes sense.
BTW, you can buy an air chisel at Harbor Freight or Lowe's for less than $25.

Thanks Bill, an air chisel sounds like a good investment. Next time I'm at harbor freight, I'll add one to my collection of cheap and useful tools.
The saga of the stuck pin goes on. Today I followed the plan, cut the bottom of the pin and extracted the cylindar. The remaining portion of the pin is still badly stuck in the cylindar, but at least it's out, ready for me to attack with the 10 ton bench press.
But before I do, I started to inspect this extracted swing cylindar, origionally removed because both were leaking, and noted that the ram has a bit of a chunk taken out of it from the previous user.
QUESTION: Should this cylindar be repacked or replaced? If replaced and I was planning to repack the other one too, should I replace it's sister? One advantage to replacement is it would make it less necesary to try and get this darn pin completely out.
This is turning into a major job. Please tell me not everything will be so.....

Take the cylinder to a local Hydraulics shop. If you don't know of one, stop by a construction equipment dealer and ask. It can probably be repaired. There is no need to replace both cylinders if only one is damaged. Balance, etc. is not a concern.

Take it to a hydraulic shop, they can fix it for a fraction of replacement cost, and they can press out the pin as well!
Okay folks, here's the follow-up on this story that is taking much much too much time and energy. I finally cut off the second pin, extracted the second leaking cylindar, and see that it too has a (smaller) nick in the ram. Tried to drill out the pin per my dad's instructions and only managed to make a pin with a lot of holes in it and several dull drill bits.
Brought it in to the hydraulics shop today. They say the nick is not a problem except that it will leak when that nick sits directly on the seal, but since that should be momentary it's probably not worth buying a new ram at $150. They will try to press out/drill out these extrodinarilly stuck pins and will repack the cylindars after smoothing the nicks so it won't tear the new seals, will also bead blast and repaint. Cost: $130/cylindar or $260 to have them "good as new" (sorta).
After all this aggrivation, I said "sure". Hopefully this will be my last post on this topic, unless they have some major issue with getting the stuck pins out .....Tim
