On 6th series cars there are actually two types. One bolts together. Anyway, the service manual has a section dealing with removal. They do not list any special tools other than two C-clamps to prevent the unit from separating during removal and installation. It should come off readily after use of penetrating oil.

Inside the unit is a friction disc for which there is no information (at least that I have ever found). The disc wears out and results in vibration - a very common problem with those motors. The manual also talks about lubrication and adjustment but does not detail a procedure (how about that?). So maybe somewhere is a written instruction in an old motors manual.

As far as adjustment, it is obvious that considerable force should be required to rotate the damper when running but, again, I have never seen an interference spec for the friction disc.

Hope this helps.
