marko Posted January 3, 2013 Report Share Posted January 3, 2013 All Echo Frames and spare BBs are sold with these AL-Bolts installed. So how/when did this happen? While using the original bolts? Quote Link to comment Share on other sites More sharing options...
ashleys sugden Posted January 3, 2013 Author Report Share Posted January 3, 2013 well, tarty sell steel echo crank bolts, which i might have to buy, as i cant get hold of any 15mm bolts, and even if i did get a bolt, the threads are not course, and the 15mm bolt i tried is too, course, it would just knacker the bottom bracket, thanks for the help everyone, much appreciated Quote Link to comment Share on other sites More sharing options...

stunt man t Posted January 4, 2013 Report Share Posted January 4, 2013 (edited) the bike shop says my BB is f**ked threads dont just strip unless something its screwing into causes it, ive used my echo SL bolts on loads of different types of BB all being 15mm and removed and re-fitted them loads of times and theyve allways gone straight in, do the bolts not screw in to either side of the bb or just 1 side? if its just 1 side it might be that thread on the bb if its both sides its probably the bolts being wrong size thread try the 'process of elimination' but ive uve striped 2 sets of bolts its probably the BB just a thought Edited January 4, 2013 by stunt man t Quote Link to comment Share on other sites More sharing options...

ashleys sugden Posted January 4, 2013 Author Report Share Posted January 4, 2013 I went and asked my neighbor about this as he was a pro downhill rider, he compared my echo alloy bolts to the steel ones, and he says the angle of the thread pitch are different, the echo ones are more flat and the steel ones are on an angle, he said if I put the steel ones in I could knakcer up the BB, but the other side went in fine? So the bike shops steel bots could of knackered my BB, but I still don't understand Quote Link to comment Share on other sites More sharing options...
stunt man t Posted January 4, 2013 Report Share Posted January 4, 2013 if 1 bolt has gone in 1 side but not the other its the bb thread on the side the bolt wont go in thats knackerd! lol Quote Link to comment Share on other sites More sharing options...

trials hoe Posted January 4, 2013 Report Share Posted January 4, 2013 you can use this method to check the pitch of the threads on the two different crank bolts IMG_20121225_215643.jpg Quote Link to comment Share on other sites More sharing options...
ashleys sugden Posted January 4, 2013 Author Report Share Posted January 4, 2013 How clean is the thread in the BB? ive wire brushed it, not too hard though, cleaned out with petrol, cleaned again, then copper greaseyou can use this method to check the pitch of the threads on the two different crank bolts IMG_20121225_215643.jpg ill go and have a look now thanks Quote Link to comment Share on other sites More sharing options...

ashleys sugden Posted January 4, 2013 Author Report Share Posted January 4, 2013 you can use this method to check the pitch of the threads on the two different crank bolts IMG_20121225_215643.jpg they fit together, its hard to tell as the threads are so fine, although i have just had a thought... my dad said yesterday that the start of the thread could just be gone, does this mean i could put the BB spindle in a lathe and just face it off a bit untill its good thread again, about 1-2mm?

Danny00135 Posted January 4, 2013 Report Share Posted January 4, 2013 ive wire brushed it, not too hard though, cleaned out with petrol, cleaned again, then copper grease Spray it with some gt85 or something of the sort then wipe it, you'll find it easier to see any imperfections on the thread.

ashleys sugden Posted January 4, 2013 Author Report Share Posted January 4, 2013 re tap the axle? i dont have any taps that size and even if i did the thread pitch would be too big, as the crank bolts have such a small pitch Quote Link to comment Share on other sites More sharing options...
customrider-Rhys Posted January 4, 2013 Report Share Posted January 4, 2013 lets face it you've tried it all, you either have to accept the bb is dead, but your best option is to run a tap through it to re new the threads then the bolts should go in fine! from you video though it looked like you ripped some threads off?!

ashleys sugden Posted January 4, 2013 Author Report Share Posted January 4, 2013 and does it screw out and go in fine? yeah, i can take it out and put it back in again fine Quote Link to comment Share on other sites More sharing options...
stunt man t Posted January 4, 2013 Report Share Posted January 4, 2013 yeah, i can take it out and put it back in again fine it MUST be the other thread on the bb the bolt wont go in! Quote Link to comment Share on other sites More sharing options...
