I'm trying to install a cartridge BB on my 85 Raleigh Team USA and have encountered a problem. The BB cable guide is bolted on with a non-screw bolt. I have never come across something like this, and would like to remove it to get the cartridge in. The bolt protrudes about 5mm into the shell, and interferes with the cartridge. I would like to replace it with a screw type bolt that is not long enough to interfere. It seems like my only option is force, and I obviously want to avoid this.
There doesn't appear to be threads on the bolt, and the tip looks like it is expanded inside the shell. The head of the bolt is flat and plain with no notches or grooves to get a tool on. Has anyone ever seen this before? and how do I remove it with out destroying it?
