3TJ fork assembly problem

[bmw156]

hi guys and girls
I have stripped down both forks, and changed the fork seals .
the problem comes when I put the dampener into the inner tube, and screw it in through the bottom.
The inner tube will no longer extend.
When I undo the bolt it will extend more and more until the bolt is out, then it extends fully.

Confused!
help please.

Do you mean screwing the hex head bolt into the bottom of the fork leg?

Yep I did mean the bottom bolt.

I sorted it now, the plastic bush, had got stuck in the inner tube, and wasnt allowing the damper fall through

a swift hit through the top sorted this and all if fine.

Thanks
