JohnyMilton Posted September 17, 2007 Author Report Share Posted September 17, 2007 the BB is not working right, jsut need to know how to take it out! Quote Link to comment Share on other sites More sharing options...
djb Posted September 17, 2007 Report Share Posted September 17, 2007 I had to take mine to Leeson last week after snapping the axle. How he does it is remove the circlip, heat the bottom bracket with a gas torch to melt the thread lock holding it in then smack the living daylights out of it to get it out. The new one needs to have the threads and flange milled off and then, covered in good quality epoxy/thread lock you hammer it back in and replace the circlip - piece of cake really if you have the tools.He did it all for £15 for a square taper bottom bracket, which I may add would have cost more for me to buy and he did all the hard work for me while I watched the drag racing at the nearby Santa Pod . He said if you can remove and refit he would happily supply the modified bottom bracket so if you think you can do it then just give him a call and get him to post one out to you.

djb Posted September 17, 2007 Report Share Posted September 17, 2007 (edited) Yeah, just give him a call - he's a very friendly guy to talk too and will do his best to help you out.Now I know how to do there's no doubt i'll do it myself if I have to do it again, i'd have to get the modified bb from him but the rest should be ok. Having said that i'm a hands on person who fixes aeroplanes for a living so...A small gas torch like those available in Halfords (or something similar to melt the old glue), a pair of internal circlip pliers and a big hammer (soft faced if you intend to reuse the bottom bracket you're removing) should really be all you need. Clive himself said not to be scared of hitting it which I find generally means smack it as hard as you can, repeatedly!!!The circlip is the circular clip ( ) that you can see on either side of the bottom bracket once you have the cranks off. It is a split circle with holes at each end that the prongs of an internal circlip tool will fit into.

djb Posted September 18, 2007 Report Share Posted September 18, 2007 Cos i'm too lazy to take a pic of my bike here's some found on googleA circlip around a seal - very similar to what you would see if you took your cranks off and had a look inside your bb shell:A circlip on its own:And the required tool to remove one:Now go take your cranks off and everything should become clear.Daniel Quote Link to comment Share on other sites More sharing options...
