Greetings Posted April 26, 2011 Report Share Posted April 26, 2011 (edited) I've got a serious problem with installing a Reset bb into an Inspired frame. Raped two drive side bb cups and part of the thread in the frame. The non drive side cups screws in just fine. Tried other bb's with steel cups and they went in fine. On the 1st approach a few threads went in easily, then it became heavier over 1 rotation, jammed and was impossible to unscrew, had to be hammered out. 2nd approach - frame was tapped and faced to make sure the threads are ok, the same thing happened I've never had a problem like this. I'm well aware of the care needed when installing bb's, especially alignment and making sure that the bb doesn't jam against the non drive side cup. As part of troubleshooting I've tried installing 2 Rest bb's into Adamant, Gu, Zoo and a couple Echo frames and they all went in fine. Help!

Greetings Posted April 26, 2011 Author Report Share Posted April 26, 2011 Well it's a mess now, this is how it looks like after the 2nd cup got raped and before tapping. Quote Link to comment Share on other sites More sharing options...
AdamR28 Posted April 26, 2011 Report Share Posted April 26, 2011 Hmmm, looks very dry? All I can recommend here is spending a lot of time with the BB tap set, lots of cutting fluid, then a load of copper grease for fitting the BB and taking your time Quote Link to comment Share on other sites More sharing options...
Greetings Posted April 26, 2011 Author Report Share Posted April 26, 2011 Will do. It's dry because it was flushed with spirit while tapping. But yeah, definitely needs grease. Before this went horribly wrong, I tried installing a VP square taper bb and that went in fine. I've just measured that the VP thread is 34.6mm while the Reset is 34.65mm - 34.7mm. Do you think that aside from your suggestions it might be an idea to ever so slightly rub the bb cup thread down with sand paper? Quote Link to comment Share on other sites More sharing options...
AdamR28 Posted April 26, 2011 Report Share Posted April 26, 2011 Sounds like it cold welded in that case, bummer. I would just go over and over with the BB tap, the sandpaper won't really help. Quote Link to comment Share on other sites More sharing options...
Greetings Posted April 26, 2011 Author Report Share Posted April 26, 2011 Do you mean to say that this cold welding process could have happened in a matter of ~10 seconds? Anyway thanks a lot for your help, I was hoping you'd be the first to reply to this topic Quote Link to comment Share on other sites More sharing options...

Anyway thanks a lot for your help, I was hoping you'd be the first to reply to this topic Happens instantly Had the same with a Control frame and FSA BB (also alloy cups) a few years back, screwed in dry by hand, picked up a bit of thread - game over. No worries, good luck! Quote Link to comment Share on other sites More sharing options...
wip-bikes Posted April 26, 2011 Report Share Posted April 26, 2011 Id go with that also, just run a chaser through it a couple of times nice and slow with plenty of cutting fluid on, or if you can get hold of an actual bottom bracket tap (ones used to cut them from scratch) then try that. You might get another .05 - .08 out of it, still be a squeeze with the sound of it though. Good luck mate Always a bugger when things like this happen Quote Link to comment Share on other sites More sharing options...
Matt Vandart Posted April 27, 2011 Report Share Posted April 27, 2011 I had a tightness problem with a reset bb, what I did was half screwed in the drive side, then screwed in the non drive side all the way. I then returned to the drive side and tightened it a bit, then un tightened the non drive, then repeated until the drive side was in properly and torqued everything up. Tidy beans.
