RATTY:
Ignore the tards in the corner!!!

If its a US BB (Big one with a one piece crank) then you need to remove the pedals first, then undo the lock nut first  (remember its a left hand thread!). Then remove the washer, then undo the the large one the same way. Remove the bearing race and slide the crank out the other side. :daumenhoch:

GavinKent:
thanks all!!  ive managed to undo the nut and now the bigger one, with the slot like a screw - i was able to undo the same way but getting tight - do i use a hammer and put screwdriver into slot and tap a bit??? 

spesh:
no turn it back and give the thread a clean,it should unscrew without much effort :daumenhoch:

GavinKent:
ahhhh, i started undoing it the wrong bloody way again!

now ive managed to do the difficult bit, i just need to find a spanner to undo the bloody pedals!
