Cleaning and greasing
Dismounted shrink discs do not have to be taken apart for cleaning and regreasing prior to
reinstallation, unless they have been used in a very dirty environment.
After cleaning, recoat the tapered surfaces using a solid lubricant with a friction coefficient of
0,04, e.g. Molykote D321R or similar.
