Trying to get the cranks of my mtb but when using the crank extractor rather than taking off the cranks it just took the thread off instead.
I've had a look around the net to see if there are any hints or tips to get the sods off now but it just seems to be people saying "buy a crank extractor" followed by "Yeah man, just buy the tool, its only like 10 bucks". Which is of little use to me now.
I've also seen people advising to pour boiling water on the cranks, which seems a nice theory but I cant see it actually working.
I've given them a bit of a wiggle and a yank along with some light tapping with a hammer and some sprays of WD40 and it doesnt seem like its going to budge.
Ideally, I'd like to keep the cranks so I'm looking to avoid bringing out the mjolnir and going full whallop but its looking increasingly likely that this could be the only option left unless anybody has any suggestions?
