AlexC Posted August 21, 2006 Report Share Posted August 21, 2006 Ok, so I brought the Echo 4 bolt booster for my Onza T-Pro a week ago, we fitted it with no problems at all - the screws went in fine and got it all setup. A few days ago I was riding to the place I was going to do Trials and my freewheel decided to eat my jeans, in the process it also pulled my wheel out of line and slightly bent the Drive Side Tug, no problem we got it fixed apart from the brakes were slightly out of line, so tonight before we were gonna go riding I was going to re-align my pads...... that's where the fun began Round 1So we began undoing the bolts so we could align them, got to this one bolt and it would not move at all. After about 10 mins of trying to get it undone the bolt was rounded. Round 2Lets get a hacksaw and cut a groove in it so we can use it like a normal screw..... it didn't like that either, wouldn't even move a MM...Round 3Up to my Grandads I go, he can make or fix anything so we thought if he can't get it out, no one can. Out come this massive lock grip plyer's and we attempt to get it out, with again .... no luck.Round 4Ok, lock grips wont do it - let's get a Heat Rod and heat the bolt up a bit ( Not entirly sure why, but he knew what he was doing! ) After we heated it up a bit, we got the lock grips and try to unscrew it again, you guessed it - with no luck!Round 5At this stage, I was thinking if I should buy a new T-Pro Frame or get a different Frame. Out comes the blow-torch - We heated the bolt up untill it was glowing red hot, then instantly put cold water on it hoping that the bolt with contract enough for us to unscrew it easierly......Nope! This thing isn't going anywhere.Round 6*lights blow-torch again* Again we heated the bolt up to red-hot, but this time we bent the bolt at the top over - so it look like an upside down 'L' - hoping that this would give us more leaverage ( Further away something is from the center, easier it is to turn/pull right ) but no, this little bolt was not going anywhere fast. After about 5 mins of using the new shaped bolt to attempt to unscrew it, it snapped. Round 7Lets drill the bugger out! Out comes the hacksaw and we cut the bolt level with the frame. Next out comes the drill and begin to drill it out ...... good god those bolts are tough, tooks us a while to drill it out, but we did in the end drill it out. Now that it's drilled out, we need to get the outer of the bolt out of the brake mounts ..... fun fun fun.Round 8Ahhhh, the end is in sight - after about 30 mins of trying to get the outside of the bolt out, we did it! Finaly .... but not Brake Booster untill I get a new bolt for it. So yeh, Make sure your bolts go in properly =) *sleeps* Quote Link to comment Share on other sites More sharing options...
Tidytrials Posted August 21, 2006 Report Share Posted August 21, 2006 Theres a lesson to be learnt here mate!!grease your bolts!!!!!!!!!!!!and if your going to try and heat something, trying heating whats on the outside! heating the bolt would have made it expand inside the brake mount!!! instead you should have tried to heat the mount, thus expanding the outer of the threads, not the inner!Of course if the brake is still on the mount! You're fecked!! Quote Link to comment Share on other sites More sharing options...
joshywa Posted August 21, 2006 Report Share Posted August 21, 2006 you dont heat the bolt to loosen it in an alu frame heating the bolt expands it !!! thus making it fit tighter which could crack brake mounts ect.... try getting a bolt thats snapped off 4mm bove the mount out that required heating the frame and tac welding a rod on to get it out Quote Link to comment Share on other sites More sharing options...
26inch Posted August 21, 2006 Report Share Posted August 21, 2006 how is you not using copper grease the boosters fault, also that was a rather boring story, the beginning was ok but it needed more detail for the middle and ending, use adjectives a poor overall effort Quote Link to comment Share on other sites More sharing options...
AlexC Posted August 21, 2006 Author Report Share Posted August 21, 2006 also that was a rather boring story It twasn't suppose to be the most exciting story ever writen =) Just saying what happened! Middel and Ending I began to give up as I was so tired and started doing something else how is you not using copper grease the boostersNah, wouldn't of helped. On the T-Pro frame the welding goes into the brake mount threads, so if you look down inside it you can see the weld. What had happened is we must of over tightended this one bolt and it had cut it's own thread into the weld, and once that was in the weld it was never comming out without a fightheating the bolt expands it !!!Yeh I know, but cooling it again will make it contact more - and I would rather take a blow tourch to a bolt than my frame any day!

AlexC Posted August 21, 2006 Author Report Share Posted August 21, 2006 We tried doing that, Matt - but it was in solid, that bolt was not comming out! Quote Link to comment Share on other sites More sharing options...
ManxTrialSpaz Posted August 21, 2006 Report Share Posted August 21, 2006 Are you sure you tried tose wrong way round drill bits? The blot would have out, just like that. And in your story, you did not once mention aplying grease to the bolt...I hope you did. Otherwise you'd be quite silly. Quote Link to comment Share on other sites More sharing options...
AlexC Posted August 21, 2006 Author Report Share Posted August 21, 2006 you did not once mention aplying grease to the bolt Yes, I did =)Are you sure you tried tose wrong way round drill bits?Yep, we tried them - didn't work. It was in solid Quote Link to comment Share on other sites More sharing options...

Euro Braker Posted August 21, 2006 Report Share Posted August 21, 2006 I neally had the same done but I drilled out middle and used 3 different tap sizes to thread the hole I drilled inside the bolt and it came back to how the thread was originally ment to be Quote Link to comment Share on other sites More sharing options...
ben Posted August 21, 2006 Report Share Posted August 21, 2006 you could have tryed useing an easy out they only tend to work on fairly unstiff bolts and this sounds like it was in a treat another thing iv nto used but is meant to be well usful is an impact driver it like a screw driver you hit and it spins id have thought that could have been helpfull i wouldnt have thought the bolts would rust in very fast though even if you hadnt greased them seems strage to me if you had only just iftted the booster was the bolt bent at all?

AlexC Posted August 22, 2006 Author Report Share Posted August 22, 2006 Your trousers getting caught bent your chain tug? Yeh I know! I did a good job of it - when it got caught it pulled the whole wheel towards the drive side and in the process, bent the tug. i wouldnt have thought the bolts would rust in very fast though even if you hadnt greased them seems strage to me if you had only just iftted the booster was the bolt bent at all? I don't think it did rust, we think that we over tightened the bolt ( Or there was slightly more welding on my frame than normal ) and the bolt cut a new thread into the weld, and once it was in that there was no hope. My grandad said he's seen it happen before, but this was the worse one he'd ever seen! wd40 and bfi (brute force and ignorance) seems to work for me Oh there was a lot of brute force!

Rob CRX Posted August 22, 2006 Report Share Posted August 22, 2006 next time it goes in make sure its greased up and buy decent tools that fit perfect and it wouldnt have rounded off (if you use them properly) Quote Link to comment Share on other sites More sharing options...
Greetings Posted August 22, 2006 Report Share Posted August 22, 2006 The easiest thing you could have done was to heat the frame up with a blow torch. Aluminium expands very much quicker than steel. And before you say that something will happen to the frame - no, it won't. Not at such low temperatures. I used this method for unscrewing chainrings, freewheels, bb's and it always worked fine.

AlexC Posted August 22, 2006 Author Report Share Posted August 22, 2006 next time it goes in make sure its greased up and buy decent tools that fit perfect and it wouldnt have rounded off (if you use them properly) Erm, it was greased up and they were decent tools - the reason it rounded off was because it was stuck in so tight, that it would not turn at all - so all the force we were putting into trying to turn it with an alan key, just rounded it off. The most expensive alan key on the planet would not of got that out!And before you say that something will happen to the frame It probably wouldn't have done anything like you say, but I really didn't want to incase it did - hell it's only a week and a bit old! Well atleast it's sorted now =) Quote Link to comment Share on other sites More sharing options...

Reinold Posted August 22, 2006 Report Share Posted August 22, 2006 Thats an interesting story, i can't really comment on the things you could have done to make that story an easier experience but in that situation i would have panicked, sat down in a dark corner where i would plot to get it out then in rage take my anger on my bike praying that i would have made things easier but leaving me no closer to fixing my bike ryno Quote Link to comment Share on other sites More sharing options...
