Laytonnz,
My go to list for stuck things:
-get a wire brush wheel on it to remove as much rust, paint and other debris as possible from any joint lines
-penetrating oil made of 1/2 Automatic Transmission Fluid (ATF) and 1/2 acetone. The acetone thins it so it wicks in any opening and then evaporates quickly, leaving the ATF oil behind.
-a thousand small whacks are better than a few big whacks. I cut off some chisels from my air powered chisel hammer and use those for things like stuck brake drums, etc. You can spend some time hammering gently without breaking a sweat and things often pop apart without broken metal or black thumbs.
-more inspection and thinking....does it really come apart the way I think it should? Did a former owner weld it?
-add heat. Sometime tricky if low-temp alloys or near bearings, seals, etc. It is best if you can expand the "outer" thing and create more play between them, but I have also had to heat the "inner" thing; it can at least crack the old rust and get things separated. Be careful of any penetrating oils used earlier!
-a successively larger selection of hammers......
-can I break or cut-off one piece and save the other? Which part is sacrificial?, does it require an angle grinder, a hammer and chisel or cutting torch?
I am sure there's more.
