This is an older cup and cone adjustable BB. If the crank bolt took an Allen key, no problem, but I can't get the socket in there to remove the bolt now because the broken crank puller is jammed in there.
Is there a way to remove the BB if I remove the left (non drive) BB components? I have that side dismantled but it still doesn't give me enough room to lock onto the drive side BB to turn that. Any suggestions are welcome. I am replacing both BB and cranks, so suggestions which destroy either are fine. Thanks.
Thats not an enviable situation! Unfortunately the drive side is ALWAYS the side thats most difficult ro remove, and to access it effectively you`ll need the crank arm off. The >> assembly can`t be removed otherwise.
So the easiest ( which will still be a pain) strategy will be to split the crank on the axle. Since the bolt is still anchoring it - it`ll need to be split on two sides around that bolt.
I wouldn`t suggest even trying to cut the axle - you`ll damage the frame in the process. Not a job that I`d love to do again but have done in the past . An Xacto saw will cut aluminum OK and a hammer and chisel will force the seperation. You`ll be good for a couple hours and if you lose patience you could end up damaging the frame so take it easy.
