DrEvil270183 Posted January 25, 2006 Report Share Posted January 25, 2006 Hello, im stuck. was service the old bike, tightening brake bolt back up on four bolt mounts and one snapped. there is about 3/4mm sticking out of frame. any good idea to get it out, threads should be okay so drilling is a last resort.ive tried plyers, an cut abit into the top of remaining bolt to use screw driver, neither worked. any ideas would be great, heating maybe?? not sure cheers, Tim.

dave85 Posted January 25, 2006 Report Share Posted January 25, 2006 Chuck a bit of wd40 on it and leave it overnight, they try again.A few light taps on the top with a hammer might loosen it up a bit too Quote Link to comment Share on other sites More sharing options...

Gaz M Posted January 25, 2006 Report Share Posted January 25, 2006 get some mould grips, clamp it uber tight, and just screw it off Quote Link to comment Share on other sites More sharing options...

anzo Posted January 25, 2006 Report Share Posted January 25, 2006 Do not use heat, it will just destroy your frame.I don't think WD40 would help this much, I accept I may be wrong here, but the problem is the lack grip and leverage. Although you say you have used the screwdriver method and this hasn't worked? Which is quite suprising, if you got a good solid grip and the amount of force you put through the screwdriver would be immense, and so I don't WD40 would help this much?

2sixstreet Posted January 25, 2006 Report Share Posted January 25, 2006 If slotting the top and using a screwdriver didnt work then you may have to drill it. You dont have to destroy the threads though. Drill a hole smaller than the size of the bolt and either collapse the thread or use and 'easy-out' to extract it.

ogre Posted January 26, 2006 Report Share Posted January 26, 2006 How much bolt is sticking out? if there is a fair bit then drill a horizontal hole through the bolt and put a 1mm alan key through it and use the extra leverage from that...

Deonn h Posted January 27, 2006 Report Share Posted January 27, 2006 This happend to my frame exsept it was a clean snap (nothing to grab).We got a dremil which is like a small hand drill and drilled it about halfway through the bolt .Then got a small allen key and tapped it into the hole with a hammer.Then just unscrew the bolt slowley with the allen key.Do that.It works amazingly.ThanksDeonn.P.s Andy amos did mine.His addy is andymontyti@hotmail.com.
