Crank Puller Broke off in crank arm.
 

I foolishly didn't remove the nut from the bb axle before trying to pull of the crank. Needless to say, the bit that screws into the crank arm has broken and stayed inside the thread. Is this frame garbage? Can I still take out the part somehow? It is a nice vintage fuji frame, I would hate to throw it away.

Thanks

If the pusher bolt is out the pressure should be off and you should be able to work the puller out with a pair of pliers, of other creative means, I'm amazed it even fit around the bolt (most don't).

If that fails you can have a shot remove the entire BB by removing the other crank, and the cup behind this crank and taking it out with the spindle attached. Give it a shot trying with the pliers or another way, but don't go crazy and make it worse. A decent, experienced mechanic might be able to get the puller out even if you can't, and that would be the best solution.

The other option if the left crank is the issue is to use an abrasive cut-off disc and cut the spindle behind the crank arm giving access to the BB so it can be removed the normal way. If you don't have the tool, but have a decent relationship with an auto mechanic, he can do this for you.

You probably didn't harm the frame but the crank, or at least one side, is now toast. As FBinNY recommended, there are several ways to correct this problem and, if all else fails, take it to a bike shop and have them extract the dead body.

Might be easier to cut the crank arm to split it off the spindle (cutting alloy instead of hardened steel). Could probably even save the BB that way if you so desired.

True, but neither should be necessary. A decent mechanic should be able to get the crank off.

If the OP doesn't want to let a pro try to bail him out, he can use a hacksaw to cut across the crank arm hub opposite the arm about 3/8" from the center (just outside the crank remover). He should cut parallel to the spindle until through, then use a coarse file to get as close to the spindle as possible, then use a pipe over the arm for leverage and bend til the filed end flexes open and the arm comes off. This isn't all that easy with the nut still in place, but is still doable.

I repeat that heroic measures shouldn't be necessary, and therefore saved for last resort only. If the bottom of the puller can be removed, odds favor saving both the crank and BB for reuse.

....to the OP....if you are
swayed by the voice of sweet reason here, you may never experience the
incredible feeling of joy and virility associated with slicing something off your
bike with one of these.....

Sorry Francis, but a man's gotta do what a man's gotta do.:love:

Absolutely, it's why I suggested the cut-off disc on spindle rather than the crack the crank. Overkill power trumps hand work any day. And it's much more dramatic.

Following the time honored tradition of this forum, why make do with what you have and a bit of finesse when you can go out and "invest" an expensive tool that you'll probably only ever use once?

Thanks for all of the great advice. I'm probably going to remove the crank from the other side then take out the whole axle. Thank God, it would have been a shame to waste such a nice vintage frame to such a silly mistake.
