chris mac Posted June 12, 2006 Report Share Posted June 12, 2006 firstly,loosen your crank bolt which will either be a 8mm allen key or a 10mm socket, but depending on how hard you ride then this bolt will be very tight, you may have to use a mechanical advantage e.g use a old seat post over the allen key or ratchet. to gane extra leverage.secondly,take the completely out and wobble the crank off, (if your tapers have conciderably worn then u might not have to use a crank puller.thirdly,take one of your empty beer cans or coke cans and cut using sissors a piece of can that will be approximatly the width and circumferance of your worn taper, i advise that you use a glove of some discription to stop you from slicing yourself.forthly,wrap the can round the taper tightly and place your crank over the top of the can. and on the taper as you would normally do it, and just simply thred your bolt in and tighten as much as you can.fidthly,go in the street and ride round for a couple of minutes, this just simply beds it in. check to make sure that your crank is still super tight and then your ready to ride with un wobbily crank.i have to do this evey week or so because i ride most nights but thats because im to lazy to keep tightening the crank bolts up after evey night but... life goes on hope ive helped, chris Quote Link to comment Share on other sites More sharing options...
Ash-Kennard Posted June 12, 2006 Report Share Posted June 12, 2006 validation, i will use this method when mine go, although, if maintained peoperly this wont happen. Quote Link to comment Share on other sites More sharing options...

Greetings Posted June 12, 2006 Report Share Posted June 12, 2006 Been using this method ever since I started riding trials. A beer can is a good way out, but the best you can use is a razor (these large flat ones you buy in a packet). Cutting it is a problem, as you wrote it's pretty dangerous. Razors are much harder than beer cans, and thus won't get pulverized - a can will in the long run and you'll have to replace it. You can also do this with an ISIS axle. It's slightly more difficult, and you can't use razors because they'll break. If anybody is interested in how to get it properly fitted (not at all easy as the spline is complicated), I'm happy to help. There is however a quick method of doing this, without having to use three hands at once. It's sometimes a good idea to use this method even if the spline isn't loose. The tighter the cranks sit on the bb, the longer they'll last before they start rounding off. Quote Link to comment Share on other sites More sharing options...
chris mac Posted June 12, 2006 Author Report Share Posted June 12, 2006 Wow i never knew there was a way to fixed buggered cranks.Does it creak or anything?providing that you tighten as much as humanly possible than this wont creek. well at least it has never happend with methey generally creek when/if they come loosechris Quote Link to comment Share on other sites More sharing options...
monty221pr Posted June 12, 2006 Report Share Posted June 12, 2006 my friend used chemical metal to fix a rounded square taper,it is just two compounds you mix together one being a hardener. mix it up fill the crank maybe a little on the bottom bracket fit the crank as usual then leave overnight to dry , as far as i know this is a permanent fix meaning no need to keep replacing bits of cut out beer cans Quote Link to comment Share on other sites More sharing options...
adamtrials Posted June 12, 2006 Report Share Posted June 12, 2006 Wouldnt that stick the cranks on permanantly? Quote Link to comment Share on other sites More sharing options...
joshywa Posted June 12, 2006 Report Share Posted June 12, 2006 easiest way is to use strips of old measureing tape allready cut for youjoshywa Quote Link to comment Share on other sites More sharing options...
redroy Posted June 13, 2006 Report Share Posted June 13, 2006 Also fling some loctite on the on the bolts then tighten up and wait to dry. Just dont over tighten the bolts or they may snap and then you'll have half a bolt stuck in ur bb Quote Link to comment Share on other sites More sharing options...
Onza Kieron Posted June 17, 2006 Report Share Posted June 17, 2006 validationHe speaks the truth, I did this on my bike and it worked and I didnt have to change it until my pedal threads went.Great idea, unlike locktiting the bolt in as if your tapers are too shagged then the arm still wobbles, maybe this methoed teamed up with the locktight method will be good.

PaRtZ Posted June 17, 2006 Report Share Posted June 17, 2006 Wouldnt that stick the cranks on permanantly?no, chemical metal is simply that, It can be applied to a surface and "left to dry" so to speak until it becomes hard, then the crank slides on. Im overall sceptical about using this stuff but im a cynical c*nt anyway. Didn't believe the moving dragon head illusion until i made one and put it above my pc......its looking at me right now as it happens Quote Link to comment Share on other sites More sharing options...
