My ‘85 Westy is making a big noise when I switch the A/C on.  I took the cover off to see if I could do anything with it.  The only thing I noticed was that the rotating part is somewhat loose, thus can touch the casing.  Sure, I would like to take it out and fix it if possible, but I can’t see a way of doing it.  I don’t think, I would like to cut the whole thing open.

Is there anyone who would know what to do with this?
