As I said, I would not touch any part of the heads or positioner
whole assembly can be removed as a complete 'module' (as is the case in the
RA60). I also would not attempt to dismantle the spindle.
But often the complete spindle and bearings can be unbolted and lifted out. On
a servo-positioned drive (as I believe this is) this will not affect
replacing the complete spindle assembly was a field repair on most such drives.
Things like the spindle motor (I assume this drive is belt driven),
blower, etc are
not that critical and can be removed without problems.
Is the a maintenance manual for this drive available. It should give
the order for
removing parts (basically don't do anything that involves removing heads!) and
tell you if any alignment is needed when replacing them.
