OOPS! If there is any contact there, that means that the bushing on the
input shaft is considerably worn, and the replacement is generally not a
do-it-yourself job.

Visible grease is also not good. Try softening the grease with a drop or
two of meneral spirits so you can wipe it away with a soft cloth or a
Q-tip. The spirits may also help to free up any stiff bushings. When it's
clean and dry, lubricate the shafts and bushings with a drop of very light
machine oil (a.k.a. sewing machine oil). If you still have rubbing of the
rotating parts it's time for a rebuild to restore the bushings.

procedure? It would appear I would have to take the needle and faceplate
off to get it apart.
Cleaning of course. Taking it apart is a little risky unless you have
magic fingers. The needle is glued onto the flat face of a brass hub which
is press fit onto the shaft. Pulling on the needle may pull the glue joint
apart, and in the end it may be hard to glue it back in place so it will
stay. Prying behind the needle with a screwdriver may bend the shaft
before the hub comes loose, so be carefull. Maybe use two small
screwdrivers and pry on opposing sides to pull it straight off. Try not to
disturb the clock spring on the needle shaft. Those thinks are so thin and
flimsey that they're very easy to damage and very hard to fix afterwards.
Good luck,
