KurtiisBrookhouse Posted May 12, 2010 Report Share Posted May 12, 2010 Hi guys, I was putting my back wheel on last night. i went to ajust my brakes and i tightend them to tight and the frame threaded so i was just wondering what i could get done to fix it?

Sam T Posted May 12, 2010 Report Share Posted May 12, 2010 (edited) helicoiling. I dont know much about it, but im sure somebody else will pick up on it | Like he has V Edited May 12, 2010 by TrialsSam Quote Link to comment Share on other sites More sharing options...
PeanuckleJive Posted May 12, 2010 Report Share Posted May 12, 2010 Tartybikes can helicoil it for you, as can most engineers really. They drill the hole to a bigger size, tap a new thread and then put an insert in it which is the same thread as original so the same bolts will work Quote Link to comment Share on other sites More sharing options...
WIGAN ?? Posted May 12, 2010 Report Share Posted May 12, 2010 how long is the bolt??, if its a short one then it'l have just taken the top few threads out just use a longer bolt, if not then either coil it, jubelee clip or put a nut under the clamp Quote Link to comment Share on other sites More sharing options...

craigjames Posted May 12, 2010 Report Share Posted May 12, 2010 Don't bodge it with a jubilee clip and certainly don't drill it through and use a nut that's for sure! Either take it to a local engineering firm or send it back to Tarty and get it helicoiled and it will be as good as new. Quote Link to comment Share on other sites More sharing options...
Twista Posted May 12, 2010 Report Share Posted May 12, 2010 Go here: CLICKY £20.60 for 20 M4 helicoils and all the tools to fit them (its very easy). Can't say fairer than that, I always make sure I've got these lying around, just in case! Quote Link to comment Share on other sites More sharing options...

Twista Posted May 12, 2010 Report Share Posted May 12, 2010 Aren't brake clamp bolts M5? Lol, your right, sorry, been a long day THIS LINK £21.40 then, still cheaper than a new frame/having them repaired Quote Link to comment Share on other sites More sharing options...

Revolver Posted May 16, 2010 Report Share Posted May 16, 2010 Roflcopters. Frames come threaded anyway. The word you're looking for is stripped. As above, helicoiling is the solution you're after. I dunno how people destroy their threads, I tighten my mounts up really tight and (with the exception of the leeson I had, which pretty much stripped when you showed it the bolt,) I've never stripped a brake thread, even on my ol' ciguena.

Tux07 Posted May 17, 2010 Report Share Posted May 17, 2010 (edited) i found the best way was a to drill out the stripped bolt hole and press fit a shim that makes it back to original size then thread that, same method used to fix bb's etc also a dab of something i think is called alpoxy to help really stick them shim in works far better than a helicoil- used to helicoil parts on old brit motorbikes most bolts no matter how hard a rider you are will be at the correct torque setting at a quarter turn past the point where the allen key get stiff/finger tight and don't forget the drive the bolts back and forth through it's thread to make sure it's clean etc too early for me,translate my half awake typing to suit your needs Edited May 19, 2010 by Tux07 Quote Link to comment Share on other sites More sharing options...
PeanuckleJive Posted May 17, 2010 Report Share Posted May 17, 2010 most bolts no matter how hard a rider you are will be at the correct torque setting at a quarter turn past the point where the allen key get stiff lolwut? good advice right there for anybody who has a slightly dodgy or dirty thread that has a tight spot...

forteh Posted May 17, 2010 Report Share Posted May 17, 2010 most bolts no matter how hard a rider you are will be at the correct torque setting at a quarter turn past the point where the allen key get stiff Thats all well and good but define stiff, are you talking long series allen key or little multitool? The problem is most people dont know how to use spanners/allen keys properly; greasing the threads makes it much less likely to strip aswell Quote Link to comment Share on other sites More sharing options...
Captain Scarlet Posted May 17, 2010 Report Share Posted May 17, 2010 Just a recommendation for anyone looking for thread repair, if you can, go for a Time-sert insert rather than a plain helicoil. Had this done on my frame, the difference is that the bottom 3 threads expand at the bottom locking the insert in place, making it alot harder for the insert to grip the bolt when you remove the bolt, stripping the insert from the frame (as with the normal helicoil). You also countersink the top of the hole for the insert to go in, as it comes with a little o-ring attached to the top of the time-sert, making the job look much neater and more permanent.

Stefkeeee Posted May 18, 2010 Report Share Posted May 18, 2010 You could always refresh the thread with proper tools. A local bike shop should do the trick cheers Quote Link to comment Share on other sites More sharing options...
Captain Scarlet Posted May 18, 2010 Report Share Posted May 18, 2010 But if he's lost too much thread, that would mean tapping to a large size thread, which would be a larger bolt and respectively all mounts, booster and spacers need to be adapted for it. Which really isn't worth the hassle, when a helicoil/time-sert is so much easier. Plus a helicoil/time-sert is made from steel, much stronger thread than an alloy one, much slimmer chance of stripping it. Quote Link to comment Share on other sites More sharing options...

KurtiisBrookhouse Posted May 19, 2010 Author Report Share Posted May 19, 2010 Ive got it fixed now my dad drilled through the first part of my frame and put longer bolts in. He also cut of a bit of my clamps because he said that the hole was to big for my pistons. Oh well its fixed now but thanks for the help Kurtis Quote Link to comment Share on other sites More sharing options...
Tux07 Posted May 19, 2010 Report Share Posted May 19, 2010 Ive got it fixed now my dad drilled through the first part of my frame and put longer bolts in. Kurtis won't that make the frame more likely to snap at the mounts? (i know the hole won't be that big but it's got affect it somehow) not too keen on the idea of drilling and cuts out Quote Link to comment Share on other sites More sharing options...
KurtiisBrookhouse Posted May 19, 2010 Author Report Share Posted May 19, 2010 No it doesn't go right through the frame its fine, i hope Kurtis Quote Link to comment Share on other sites More sharing options...
