I'll dismantle (and often reassemble ;-)) just about anything.
As for motors, I had to strip the punch motor in the PC04 today. I
fitted the step-down
transformer so I could run said unit, then found the motor was solid.
The bearing oil
had turned to something rembling tar. I will try to get photos of that
The only motors I am a bit careful with dismantling are permanent
magnet DC ones.
The field can demagnetise if you don't fit a 'keeper'. But I will do
those when I have to.
See the photos in my VAX11/730 album on the same site for the insides
of the TS05
As for the cabinet fan, the old bearings were rusted solid, but the
perfect, and a pair of ball races are a lot cheaper than the entire
said bearings were metric dimensions (which made them easier to get for me).
