I remember when I had to take that damn sprocket off. That mofo was seized onto the end of the crank. I was unable to drill into it to use any type of puller, so I ended up cutting into it with a dremel cut-off wheel. I cut it on the top, bottom, left, right, diagonal, the other diagonal, keep cutting away sections and try to jam a flathead screwdriver into the cuts with a hammer to break it open... all while trying not to touch the crank with the cut-off wheel. Yes, I did nick the crank a bit, but after a long time, I made swiss cheese out of that mo-fu@#%!!! Finally was able to break it off.
Oh yeah, I also used a drill to drill into the cuts where they were close to the crank, cause the cut-off wheels couldn't go in too far without slicing into the crank itself. One of the worst things I've been through... When you finally do get it off, be sure to sand down that part of the crank a little bit to get the rust off and put some anti-seize there so that the new sprocket doesn't get stuck on anytime in the future. Good luck bro!!!
