Azarathal Posted June 10, 2011 Report Share Posted June 10, 2011 I think he means the crank removal threads. Quote Link to comment Share on other sites More sharing options...

narrowbars Posted June 11, 2011 Report Share Posted June 11, 2011 Something I,ve done before is: Boil a kettle full of water, then pour the water over the taper end of the damaged crank arm. The alloy will expand slightly and alowl you to knock the crank are off with a block of wood / hammer. Good luck Quote Link to comment Share on other sites More sharing options...

Greetings Posted June 11, 2011 Report Share Posted June 11, 2011 On 6/11/2011 at 1:28 PM, Pepo09 said: yes that should work but where can I get that! That's an automotive tool, you should be able to find it in any store which deals with such tools. They're used for removing hubs and bearings. What almost always works is just undo the crank bolt and ride... the crank will fall off. Quote Link to comment Share on other sites More sharing options...

Hammer + chizzel (or something less sharp would be better) get behind the crank and knock it. HARD. Or just ride it, it will deffinitly come loose eventually Quote Link to comment Share on other sites More sharing options...
Dec Whiteoak Posted June 13, 2011 Report Share Posted June 13, 2011 go into a local car garage and they will have something to take it off. Quote Link to comment Share on other sites More sharing options...
Sponge Posted June 13, 2011 Report Share Posted June 13, 2011 On 6/10/2011 at 9:42 PM, ireson75 said: Would one of these work? Bearing pullers normally work good. A lot of people in unicycling and a few in BMX used them for getting crazy tight Profile cranks off (which don't have any removal threads). Otherwise go with what Greetings said about riding. It will come off eventually so long as the crank bolt is off. A bit of WD40 or similar to break the 'seal' should help if it's still being stubborn!
