I'm in the process of putting new seals in my Float 32s (why do I always do stuff like this when I'm knackered?). It's all been going fine, new seals are in, air side is back together, but I've put in the damper and tried to screw the nut on where it sticks out the bottom of the leg and the damper's just rotating. Holding the top doesn't help as the bottom of the cartridge where the thread is is able to rotate about the shaft. Am I missing something obvious or have I killed my fork?
Screw the nut on as far as you can then firmly attach a pair of mole grips to it, pull as hard as you can to help the shaft dig in to stop it rotating.
Are you using the old crush washers or new ones. The old ones can bind and turn the shaft. If so hold the fork horizontally and use downward force to screw the washer on first then spin the nut on. It should bite and hold once it reaches the end of the thread. You haven't killed anything yet.
It'll be easiest if you just lean on the fork brace and compress the forks lowers as you tighten the nut on (assuming the fork is on the bike), no need to use new crush washers although you should have new ones in the seal pack.
Thanks for the comments, initial panic over. The damper is now in.
Unfortunately both the lockout lever and rebound knob are jammed solid.
I'm giving up and going to bed.
Sounds like you were using old crush washers as above. New ones help lots.
