Front forks damper bolt
ColinHH:
I am putting new front fork boots on because the original ones had split, so also decided to change the oil seals whilst I had the forks off anyway. However, I am having a big problem in removing the lower allen bolt that holds the damper in. The first one I tried was so tight that I was concerned that I might strip it. Eventually after using a long tube to get some more leverage it finally started to turn. But now that is all it does. So the damper is obviously spinning in the tube. I think there is a special tool that you can buy, but want to avoid that if possible as I want to try and get it back on the road this weekend. So any suggestions or tricks as to how to get the bolt out? I have tried putting the spring back in but that doesn’t put enough pressure on the damper to stop it from turning. I haven’t tried the second one yet, just in case I have done something wrong with the first one.
Bryanj:
Its a standard allen bolt, use a drill that just fits in the hexagon and drill the head off then the piece will unscrew from the damper, in future the FIRST thing to do is undo that bolt
Mike_Berkshire:
I had the same problem Colin. 2 things to try: 1) put the spring back in and tighten down the top fork nut to compress it if you have taken it off. The pressure from the spring can stop the turning and allow removal of the bolt or 2) use a broom handle and tap 2 panel pins into it so that you can push this down the fork tube where one panel pin sits either side of the roll pin in the bit that turns round - I did this and it worked.
ColinHH:
I tried putting the spring back in, but no joy. Will try the broom handle and panel pins tomorrow. If that fail then I will drill them out and replace the bolts.

The spring in and the broom handle thing worked for me no problem.
