AHA!  Didn't think of that  :-[  If it is the BB, then a little patience and some lube will be required but you should be able to clean the thread out using the BB nut failing that you may need to go to a machine shop and see if they have a thread cutter they can run over it for you to clean the thread up  :daumenhoch:.

Taipan:
yep its the bb thread,cant do it with the bb nut its really tight and seems to be making it go on cross threaded if I pushed it? the threads are perfect bar the first one :(
