indianatrials Posted June 19, 2009 Report Share Posted June 19, 2009 GREASE IT! Then you wont have the &*() of a bb stuck in your your frame for ever more. Sorry im pissed off like crazy atm, the previous owner of my bike didnt grease the threads, and its ceased in there Quote Link to comment Share on other sites More sharing options...
Muel Posted June 19, 2009 Report Share Posted June 19, 2009 Did you get the bb shell tapped and faced first? Might be an idea, you could probably still get it in if the threads were tapped to clean all the laquer out of them.If the worst comes to the worst you can get the sheel reemed out with a steel insert fitted into it.

Muel Posted June 19, 2009 Report Share Posted June 19, 2009 No, they reem the bb sheel out so it's smooth and press fit an insert in, the insert is normally just a steel tube with a thread on the inside. Quote Link to comment Share on other sites More sharing options...

Id consider doin that on a brand new frame even if it didnt have problems. As long as it wasnt too expensive. Quote Link to comment Share on other sites More sharing options...

Muel Posted June 20, 2009 Report Share Posted June 20, 2009 I'd get an insert put in there, the threadless bbs are a bit shit from what I've heard. (Axle and bearig strength, they're designed for xc/road not trials).I've never had to do it, but a lot of bike shops can do it or get it done. It might cost £30+, but at least you'll be able to run a proper BB. Quote Link to comment Share on other sites More sharing options...

It might cost £30+, but at least you'll be able to run a proper BB.yeah that is definately a possibility , sounds like a good idea , i think it could be worth trying to re-tapp it as the threads arent to badly damaged (my bb cups got the wurst of the damage) and could probably be sorted with a bit of a clean up with a tap . then if that doesn't work i'll go for the steel tube optiondoes anyone know if tartybikes (or local bike shop) would be able to re-tap the threads to clean the damaged ones up? (would rather a professional did it as I dont want to mess the frame up anymore )I know they offer a workshop sevice that cleans up fresh threads on new frames but would they do the same with damaged ones?thanks very much to everyone who has contributed!

afrobot Posted June 20, 2009 Report Share Posted June 20, 2009 As a wrench, I have never heard of heli-coiling a BB shell. My advice: Re-tap, make sure you are putting it in correctly, and use green loc-tite. You will only have one chance to do this. If you are not sure, take it to a shop. The 20-50 you spend will still be less than buying a frame. Which is what you will be doing if you muck it up again. My rule of thumb is, if it will not thread in by hand , tap it, the threads are poo. Quote Link to comment Share on other sites More sharing options...
weirdoku Posted June 21, 2009 Report Share Posted June 21, 2009 I really wonder how you managed to strip the bb threads! On a new frame as well, hope you get it sorted or it will be such a waste. Quote Link to comment Share on other sites More sharing options...
Ali C Posted June 21, 2009 Report Share Posted June 21, 2009 It doesn't sound like it needs an insert yet!If you got it from Tartybikes, we would be more than happy to try and fix it for you if you send it to us, you would have to pay shipping of course but we should be able to fix it easily enough.
