Hi Roger
Have you removed both the RA and DEC axis and removed the nylon disks and given the surfaces of the disks and their respective bearing surfaces a clean with Metho or Alcohol based cleaner. I usually do this about once a year and have never had any drama with having to overtighten.
While you are at it and have the shafts out, give the bearing where the shafts run down a clean with WD-40 or something similar, you can stick your fingers down to where the bearings are and free them up, over time the grease becomes rather gluggy.
Cheers
