Oh man, how did this happen? I was using my Park crank extractor tool. I made sure that it was threaded all the way into the crank arm, but when I went to remove the crank, the threads tore off the crank rather than the crank arm coming off. And YES, I had to use a lot of muscle to do it and YES, I did make sure the bolt was off before I tried to remove the crank arm.
Now what to do? There seem to be some footprint rememants of some threads remaining
I am thinking about cutting the crank arm off. Has anybody ever tried this?
