Trying to replace seals, but I have the spinning 8mm bolt of death at the bottom ruining all my plans. They are both loose dripping oil and not stripped. I took the fork cap off so I could try and hold the damper but it still spins down below like it is a two piece kind of deal. Can't retighten either. I feel like I am missing something major. I have the Manuel. So frustrating. Any thoughts? 2000 cbr f4.

 

It would seem that there are two parts, an Oil lock (11) and the Damper (10) itself which should lock together. I can only think that the damper itself has been damaged and it spinning in the tube.
If as you say you cannot hold the damper to release the bolt then the only other option would be to try and drill it out. Or its looking for a replacement.
Seems very odd tho as the normal problem is destroying the head of the bolt.

Other folks should be along and see if they have any other pearls of wisdom to offer
