  Years ago, there was an article written in the Old Timers Bulletin (AWA) 
by Bill Fisette (sp??) about removing HRO dials.  i just remember the main 
points.  Basically, he removed the center black knob while the dial was 
still installed by reaching behind somehow, then fabricated a wheel puller 
using some strong cord and ?? and pulled the dial off, upset and all.  Bill 
apparently has restored more HRO's than I have seen so he knows what he is 
doing.  If k4kyv's approach doesn't work for you, I'll look for the 
article.  Either way let us know how successful you were.  I need to remove 
a dial, but have just put it off.
