Stuck end plug on a hyd. cylinder

Any help would be appreciated.

Plan 'A'

Easy heat (just get it hot to touch) followed by some KROIL, Rust-Solv or whatever is your
penetrating oil of choice.. Some gentle tapping
with a hammer may help here.. (not pounding)

Let it cool. As it cools, it will try and suck
the oil into the threads (as best it can anyway)
Be sure to let it cool all the way down.

Repeat plan 'A' a couple times. (or more) In a hurry ? go to plan 'B' below.

Try the wrench again. If the cylinder is not 'expendable'(i.e. you don't want to destroy it)
and it still doesn't go, go to Plan 'B'

Plan 'B' take it to a local CAT or Hydraulic shop.. they deal with stuff like this everyday and if they are any good, they will have the experience to get it off without destroying anything.

Just my 2 cents.

I'll keep working with the heat cycling and try to get it free but if not, I'll take it into a hydraulic shop rather than risk damage to the tube. I'm using a Turbo propane tourch rather than a "blue tip" wrench, for two reasons. One, I don't have a blue tip wrench yet, and two, my turbo propane tourch puts out plenty of heat. The only thing I need Oxy/Accetelene for is cutting and I'd prefer not to do any of that on this job. It's a real handy tool though and I'm meaning to get one.

Thanks again, I'll keep you posted on the progress.

If need be, I have a shop nearby that does great work at good prices. They fabricated a new shaft for my last cylinder and saved me half the cost of buying a new one. Since the old cylinder was about new to start with, they did me a great favor. They said they could fabricate any kind of special cylinder that I might need if there isn't a mass produced one cheaper.

Good folks to have around.
