I’m not sure how they did it, but my LBS was able to tap and remove the crank. It only cost me $3. Not only did they get it off, but not that the threads are back, they said I can install it again. Of course the tapping didn’t do a thing for the fact that it’s still bent, but I’m thankful anyway.
Thank you very much for all your help and suggestions, brothers. I was really hoping that the gear puller would work, though. It was only 13 dollars and I could have used it for my bearings as well. If anyone finds a cheap bearing/gear puller that could fit the gap between the crank and bearing, as well as pull the bearing please tell me. I have a feeling I might need it someday; if not for me, to help a brother
These comments are a good argument for greasing the spindle, then using a torque wrench to install the crank bolt. This produces a much more consistent result than pounding on the crank with a hammer to install it. Cost of torque wrench at Sears: about $90. Savings in grief and anguish: much more.
i reccomend putting you cranks on with a mallet and some grease in future.
and checking your cranks regularly
it is possible to cut the thread off, and then drill and tap a hole in the axle.
you can then use the same crank bolts as mtbs (get the right size tap)
you’ll need a bench drill and go slow to avoid heatng the steel up an ruining its temper,
