225 DR bearing in swingarm?

[3podd]

Hey all, bought new bearings for rear end and swingarm on my 85 225 dr. Except for the one that holds the drive shaft(inside the swing arm), and i cannot get it out!!! I tried an Arbor press with heat and lube,(may have not been hot enough, it was an acetylene torch) it also had a 6 ft bar on it. It did move about a 1/2 inch and stopped. I then tried a 20ton hydro press and it knurled the metal where the boot goes on. any ideas? if i took to a machine shop what more would they have done? and probably cost 35 bucks as well. any help is obviously helpful.
thanks!
