I hope I'll be able 1) to move the shaft 1mm up or down so
the surface in contact with the seal will be "new" and therefore
undamaged
or 2) ask a machineshop to remove a tiny bit on the spot where the
seal-
ring touches, afterwards polish it to a stunning shine....




You really need to get a new shaft. Anything else is going to be a
short term band-aid.
