Grovesy93 Posted April 6, 2010 Report Share Posted April 6, 2010 (edited) Hi guys as the title says I need help! There is a funny clanking sounds coming from my cranks and BB area and I want to take my cranks off to grease the bearings up to see if that helps. BUT once I undo that bolt on the bottom of the cranks my cranks wont come off. I don't even no if what I'm doing is right. So please could someone tell be what to do so I can sort it out. The bike I have is an Onza Comp '09 and it has the BB and cranks it comes with (don't know if saying this helps) Cheers Sean Edited April 6, 2010 by Grovesy93 Quote Link to comment Share on other sites More sharing options...
*Koxx hydroxx 2 Jack * Posted April 6, 2010 Report Share Posted April 6, 2010 (edited) sounds like you have bent your bb .. new bb should fix it but to get your cranks off , you need a crank tool , the larger bit of the tool goes in 1st , just screw it into your cranks , then the smaller bolt screws in after that , dont forget the put the small metal bit at the end though , then rench the bolt up tight , and they should just fall off .. if you need them off quick , and there square taper , which the t comp ones are , then just put a cloth round the crank arm and a heafty few wacks with a hammer should sort it all out Edited April 6, 2010 by *Koxx hydroxx 2 Jack * Quote Link to comment Share on other sites More sharing options...

JD™ Posted April 13, 2010 Report Share Posted April 13, 2010 Thank you very much, I shall be going on Tarty Bikes when I have some money and I will buy a new BB and a crank tool and while I'm at it I might aswell get some new cranks. Thanks again Sean Whoa Whoa Whoa, just check what's wrong first... Check the pedals are tight and straight and turning freely first - that'll save you a bunch of time if they're f**ked. Then, if that hasn't worked, get the cranks off, either by buying a crank tool (any bike shop will have one, don't need to use tarty if you've got a bike shop round the corner [sorry Adam!]) or using the ghetto method above. That way you can check what's up before you spend unnecessary cash on things that don't need replacing Quote Link to comment Share on other sites More sharing options...
Sam Styles Posted April 14, 2010 Report Share Posted April 14, 2010 i used to have an 08 t comp, and my cranks clanked and creeked. a just greased the axles and that seamed to work. if you are still running the standard onza pedals then that could by an additional noise as i found they did.

Grovesy93 Posted April 14, 2010 Author Report Share Posted April 14, 2010 Oh ok doky thanks for the info, I shall get some grease and check its all tight but I have DMR V8s not the onza cage pedals. Cheers Sean Quote Link to comment Share on other sites More sharing options...
