Haven't tested the RA80 that came with it but the
RA60
sounds like it needs bearings BAD. Any suggestions on
restoring this RA60 would be appreciated.
I've got an RA60 that I really must get round to playing with... IIRC the
printset is on bitsavers...
As for the bad bearings, if it's the spindle itself, you've got problems.
There's no way you're going to take one apart and replace the bearings.
IIRC it's all pressed together (and sufficiently tight that no normal
gear puller will shift things), you may well find a ferrofluid seal in
there, etc.
If it's the spindle motor, you can almost certainly do something. The
motor will come apart, the bearings are most likely standard.
Of course if you're very lucky, it's just the fan ;-)
