so, putting together a new frame for a SS build and was trying to use the Truvativ Isoflow square-taper cranks & BB off an older frame I had and when removing the crank from the BB I pulled the threads out instead of pressing the crank off the BB on the drive side.
i normally watch the threads/extractor closely and try to make sure nothing like this happens, but this particular side had some threads already bunged up at the top, so there wasn't as many threads for the extractor to catch on to begin with. plus i was on lunch and trying to hurry so i could get to work putting together my new frame. stupid, i know.
i don't want to continue to thread in the extractor and ruin the remaining aluminum that is still there if there is a way I can salvage it.
so is this crank arm toast or is there some hope for this crank arm?
any tips on removing the arm from the BB w/o ruining it??
