Davetrials Posted August 29, 2004 Report Share Posted August 29, 2004 (edited) Well there has been a few post, so i thort id make a post You can either. Place a peice of wood against the crank, and bash it off with a large hammer. (be carefull, it usually flys of rather fast) Ride with no crank bolt, it will work it self loose. (only if nothing else works you should do this, as it may round your crank off) Heat it up so it expands, thus loosening the crank off. (you will most probly have a big brown stain on your cranks, were they have burnt) If all else fails, repeat step one, but bash it harder. :( From Sexymike just a little tip this is the best i cud find put the crank on a vice with the bb inbetween (meaning u need to open it a touch) u will have to get someone to hold the bike to put the bolt into the bb and hit it, so that the bb *and bike* will fall out of the crank as it remains on the vice Easy money. :S Edited August 30, 2004 by Davetrials Quote Link to comment Share on other sites More sharing options...
Rob Thomson Posted August 30, 2004 Report Share Posted August 30, 2004 The old "Boiling Water" technique always works well....Take off the crank bolt, pour some water (boiling) over the crank arm/BB area then twat it with a hammer.... :- Quote Link to comment Share on other sites More sharing options...
Si Posted September 16, 2004 Report Share Posted September 16, 2004 Or buy a decent crank remover and have no problem. I recommend a Park ccp2 :P Quote Link to comment Share on other sites More sharing options...
Monkey Posted December 3, 2004 Report Share Posted December 3, 2004 I used to have a tool that looked like a wedge with a bit cut out and I used it for this purpose. I can't remember what it was for originally, but the closest I can find now is THIS which might work on square taper cranksets. It says it's a ball joint separator.

Onza Kieron Posted August 2, 2005 Report Share Posted August 2, 2005 Or if worst comes to worst get someone talented (hmmm (Y) ) with a grinder to scrub the top of the arm off. Kieron (Y) Quote Link to comment Share on other sites More sharing options...
Walleee Posted December 4, 2005 Report Share Posted December 4, 2005 (edited) Heat it up so it expands, thus loosening the crank off. (you will most probly have a big brown stain on your cranks, were they have burnt) If you heat it until the metal is discoloured/burnt, you run the risk of changing the materials properties,and without cooling them down properly you can render the cranks VERY hard, but brittle, and if that happens the next time the crank hits a rock it would shatter. Just something to bear in mind. Edited December 4, 2005 by jake1516 Quote Link to comment Share on other sites More sharing options...
Janson Posted December 4, 2005 Report Share Posted December 4, 2005 not very likely to happen unless you leave the crank in the flame and go for dinner or a night on town... Quote Link to comment Share on other sites More sharing options...
Ben Geary Posted January 27, 2006 Report Share Posted January 27, 2006 Or just leave it spray loads of WD40 around the BB and crank area leave it over night to soak all around, Come back in the morning and then do the old wood and hammer trick should come of preety easy.Well mine did Quote Link to comment Share on other sites More sharing options...
Walleee Posted January 28, 2006 Report Share Posted January 28, 2006 not very likely to happen unless you leave the crank in the flame and go for dinner or a night on town...Depends on the intensity of the heating element/flame and the crank's material too.... so it could happen in a minute, maybe even less.....

Davey Posted July 3, 2006 Report Share Posted July 3, 2006 Haha, I can't believe in a thread about removing cranks only one person has mentioned crank removing tool, and other people are talking about setting fire to things, HAHAHAHA!!!Park tool, screw in the outer bit into the crank arm, wind away, it'll get hard to turn, take a mallet to it, work taht crank off nice and slow, no bashing your expensive crank with a hammer or burning the bloody thing (christ, extreme aint you you lot!!!)!!Davey Quote Link to comment Share on other sites More sharing options...
Adrian Posted October 2, 2006 Report Share Posted October 2, 2006 used to have this struff which was like wd40 but came out black and kind of gritty, and basically it works its way into the tiniest lil pinholes or wateva and gets to places that wd40 or tf2 or wat ever you use would never get and thats what i used to get my cranks off, also yea jus get some boiling water pour it over the CRANKS (try to avoit the bb) and the cranks will expand slightly which should make it easier, and also if your cranks are alu and thee bb is steel, then the cranks will expand at a higher rate and will come off easy... cheers.... adrian Quote Link to comment Share on other sites More sharing options...
RobinJI Posted October 10, 2006 Report Share Posted October 10, 2006 Best thing is obviosly a Crank Extractor, which everywhere stocks! even most holfords!If the thread is stripped (in which case someones been a tit ) then by far the bset method along time before heating/whacking with a hammer is to go and borrow an oldschool fly wheel puller That kinda thing, but the ones with adjustable arms, and hook the arms behind the crank, and just pull it off asif you were using a crank extractor! so easy, but I'm yet to see anyone but myself try it Quote Link to comment Share on other sites More sharing options...
Jamie_Neal Posted November 17, 2006 Report Share Posted November 17, 2006 I stripped the thread on my driveside Middleburn (and yes I was using a Park crank extractor correctly - it was just too tight) so I had to resort to a fly wheel puller (as suggested by 'Don't you just hate it when') and it works like a dream. I would recommend it to anyone stuck in the same situation - especially as it meant I didn't have to saw my Middleburn. However, I'm not sure how it'd work on non-driveside cranks - may require extra bodging. Quote Link to comment Share on other sites More sharing options...
