Simpson Posted August 1, 2007 Report Share Posted August 1, 2007 I tryed quite a lot to to get the bolt out, its rounded and really wont come out, tryed the trick of putting in a bigger allen key and gluing it in.... tryed grinding across the bolt to get a flat headed screwdriver in there.... but by the other crank bolt i think its doe up pretty bang tight.....Any other? im bang out of ideas now...... If not ill just mask the cranks when i spraying but want to do a good job onit..... Quote Link to comment Share on other sites More sharing options...

Muel Posted August 1, 2007 Report Share Posted August 1, 2007 Just an Idea, put if you used a 7mm drill bit you could drill out the centre of the crank bolt, then use a tap to clear the rest of the thread out of the bb. Mind you, when I last used a tap in a bb it snapped because I use one slightly too big. Quote Link to comment Share on other sites More sharing options...

26inch Posted August 1, 2007 Report Share Posted August 1, 2007 If its a bmx it has 3piece cranks yes?If so you only need to take one crank arm off and then just knock the axle with atached arm through Quote Link to comment Share on other sites More sharing options...
Dan6061 Posted August 1, 2007 Report Share Posted August 1, 2007 Knock the bolt with a hammer once or twice, this should shock the threads a bit and loosen them off.Doubt it'll work to be honest, but it's worth a go.Will edit if I think of any more...

joshywa Posted August 1, 2007 Report Share Posted August 1, 2007 (edited) If its a LH thread simply drill the bolt with something like a 6mm or 8mm (not all the way through, you need the tap to bottom) and thread in a m8/m6 tap. if the bolt dosen't go at 1st grind /drill off the head of the bolt to release the pressure then try tapping down again. DONT apply too much force on the tap as if that snaps you'd need a solid carbide drill bit to get that out and probably a magnet/bench drill.If the bolts a RH thread then got to a decent hardware store or look on the web for an "Easy out kit" and a hss 8mm drill, carefully drill out the center of the bolt until you deep enough to get an easy out in, grind/drill the top off the bolt and then simply push down and turn until the easy out turns the bolt out.(easy out)As was said above if it is a bmx bb (and not a euro bb) just push the axle through grip the axle in a vice, itll make the job sooooo much easier Edited August 1, 2007 by joshywa Quote Link to comment Share on other sites More sharing options...

Simpson Posted August 2, 2007 Author Report Share Posted August 2, 2007 Well i was going to jack it in and not bother spraying the dam thing, after angle grinding the bolt to try to get a screw driver in there... was just so bloody infuriated, popped out a treat as well!!! and the kid gave me a BB tool or summink which made me think, well i must have to use that... but nope just a hammer did the job! im chuffed spent 3 hours sanding the frame and its all ready to spray 2morra Quote Link to comment Share on other sites More sharing options...
