TR 250 Alternator Question

[Joseph Sholtes <joeiv@concentric.net>]

Dear Scions,

   I am rebuilding the alternator on my TR 250.  I have taken just about
every thing apart, except I can't figure out how the "Slip Ring" thing comes
off.  Is it pressed on?  Slipped on?  Threaded on? Right or left threads? I
must remove it in order to replace the rear bearing.
  It looks like it's make of plastic, so I don't want to break it trying to 
figure
it out.  Any help you can give me will be appreciated, thank you.
