3dd Posted January 15, 2011 Report Share Posted January 15, 2011 (edited) Hi. I was trying to do a bit of work/service on my BB, took non drive side bolt, that was a little bit tight, the drive side bolt was incredibly tight and I managed to round the the bolt. After was tring to make a little cut along the crank bolt and use something long and flat to undo it. The little pieces on the side snapped of in the end with no luck. I did put new BB about two month ago and gave it a clean last month and everything was fine. Would there be any ideas of how I can get this b*****d off? I am considering new BB again and drive side crank if there is no way to do it without damaging those parts. What is the easiest way i that case. Cutting the axle would take a bit of time! Thanks in advance! Edited January 15, 2011 by 3dd Quote Link to comment Share on other sites More sharing options...
j-bonham@hotmail.com Posted January 15, 2011 Report Share Posted January 15, 2011 Take it to a machine/ engineering shop if you've got something like that locally. and your not that technically handy. I've always used Easyouts for this sort of thing. Simply drill a hole in the top of the bolt and screw the 'easyout' in. It has a left hand tapered thread so the harder you turn it the tighter it bites and eventually the grip of the taper overpowers the rust holding the bolt in. http://www.brokentap.com/easy-outs.html try that mate, well worth it if it works. saves shelling out for a new bb / crank arm.

Matt Vandart Posted January 15, 2011 Report Share Posted January 15, 2011 Is it an aluminum bolt? Quote Link to comment Share on other sites More sharing options...

That sounds like a plan! *Update. We have some of these where I work by another name of "screw extractor". Thanks again J. Bonham!

3dd Posted January 16, 2011 Author Report Share Posted January 16, 2011 So drilled the hole in the bolt, took me about good 40min! Got the easyout it (fairly good quality) and it was 8mm one. Went in prety well, got tight, this is whn I got a bit scares of it snapping, still went for it and snapped the f'in b*****d! Any ideas of how to solve this?

JD™ Posted January 16, 2011 Report Share Posted January 16, 2011 I think I'd be contemplating drilling it out completely now, or hacking off the axle - looks like you've had enough bad luck with this one! Quote Link to comment Share on other sites More sharing options...
j-bonham@hotmail.com Posted January 16, 2011 Report Share Posted January 16, 2011 drilling an easy out will be even worse than drill the bolt...... as it's probly hss. (high speed steel) it could work out easier to cut the bb axel, and once it's off put the crank in a vice an tap the rest of the bb axel out of the crank. atleast that way you will salvage the crank. sorry about the snappage dude. they can be basterds! lol Quote Link to comment Share on other sites More sharing options...
LukasMcNeal Posted January 16, 2011 Report Share Posted January 16, 2011 Can you get a pic of the problem as then it will really help to see whats left Quote Link to comment Share on other sites More sharing options...
3dd Posted January 16, 2011 Author Report Share Posted January 16, 2011 I have tryed drilling the easyout, and you are right, there is no use. Not sure how long is going to take to cut. Should not be too long as its m15 thread. Will be doing that on tuesday now Quote Link to comment Share on other sites More sharing options...
