I bought some Rockshox Reba Race forks ('08 model, I think) secondhand two years ago, which were in great condition at the time and have worked very well since.
I recently thought I'd better give them a basic service to check the condition of the internals. All looked fine inside after I eventually managed to get the lowers off, but after reassembling the forks the rebound knob (bottom of right leg) would no longer turn.
I then removed the lowers again, inserted the rebound knob (essentially an allen key) directly into the hexagonal hole into the bottom of the rebound cartridge and could turn the knob without problems. However, after reassembling, I again found I coudn't turn the knob.
I should note that when trying to get the lowers off I first thought I had to insert an allen key into the hole in the rebound cartridge then tapped this with a rubber mallet - hope this hasn't damaged anything or put things out of alignment.
Any suggestions?
Cheers,
Will
Correction: I [i]can't[/i] turn the rebound knob when pushed into the rebound damper cartridge with the lowers removed.
I'm now more sure that my first attempt to remove the lowers by tapping an allen key inserted into the rebound knob hole has gotten the rebound adjustment mechanism stuck. Tried squirting some WD40 into the hole in the end of the cartridge that the knob inserts into to no avail.
After watching [url= http://www.pinkbike.com/news/tech-tuesday-rockshox-motion-control-service-2010.html ]this damper servicing instruction video[/url], I think I may need to get a new Rebound Damper & Seal Head Kit (pn: 11.4311.117.000).
Can anyone think of any cheaper/simpler suggestions?
is it possibly stuck at one extreme of adjustment?
get an allen key in there to give you more leverage and see if you can shift it.
Might as well have a go if you are thinking of replacing it anyway
Sometimes if the lower leg bolt is a bit mullered, the outside edges of the bolt bind on the inside of the rebound adjuster, so it gets stuck on the bolt and you can't turn it.
@walla24: not sure where in its range it's stuck. Tried shifting it with an allen key but think the allen socket in the damper mechanism is damaged as the allen key rotates without turning the socket.
@gee: the lower leg bolt (the hollow one that you insert the damper knob through) is in good condition.
