Guy's need a touch of help here if you can.  I've got an old set of boxxers, 2003 Race to be exact.  Now i'm pretty sure the rebound cart is screwed so I've started to strip them down, which is where I've hit the problem.  The bolt on the bottom of the rebound leg is just turning and no undoing.  I've looked down the stantion when turning it and you can see the cartridge spinning.

I've done a search and couldn't find anything so is there any way to get this bolt undone?  Preferbaly before I end up chucking them under the wheels of a tractor.....

Pic below, just so you can see which bolt it is I'm on about........

Are you undoin it with the stanchion still in the crowns??


If not that might be why

what difference would that make?

Try putting the spring back in the leg and putting the top cap back on, i've had this happen to me but with the spring back in the leg it effectively holds the pump rod in place.

With the rebound it sounds like its one of two problems, either the allen key slot has rounded or the adjuster sleeve in the pump rod has swollen (being pastic) and therefore won't allow any adjustment to be made. This can be fixed though, once you get the pump rod out of the fork put an allen in the bottom of the rod (about a 5mm if it'll fit) and gently push and this should push a plastic sleeve out. Then simply get some fine sand paper and lightly sand the sleeve. Keep checking if it turns in the rod so as you don't remove too much material, once it feels tight but you can turn with the allen key all done. This is the way i fixed the rebound seizing in my pyslos and i'm fairly sure the share the same HC2 damper and tf told me the same issue can happen to the old boxxers though its not as common.

Hope this helps, cheers!
