Think i found a new way to get off crank arms...
I was trying to get my crank arms off today, and they didnt seem to
agree with coming off. So what i did is loosen both of the bolts hold on the crank arms, then went off and rode the bike in the driveway to get them loosened, I also put the pedals parallel with the ground and kinda of stood on them and stomped, trying to put the pressure in the opposite direction it usually is. I got the left one off in no time and the right came a little later. It seemed to work great for me, since i have no crank puller. Also I usually but Park tools, but i got a recent biek catolog andthe have spin doctor tools for really cheap. Are they good quality? For the price? crank puller for $8, 13 - 19mm cone wrenches 16.99 |

But I recommend getting the right tool for the job. Mike - and watch those threads! ;^) |

As long as your cranks stay tight afterwards there's nothing wrong with it. But if you mash the flats in the crank arm (because the spindle is so much harder than the crank arm) they will begin to loosen even with the bolts installed. If that happens you'll know you rode it loose too long and you can either put a piece of a coke can on the spindle and hope for the best or put the crank arm in the recycle bin. Think of it like turning a tight steel bolt with a long handled wrench made out of aluminum, and pushing with all your weight on it - if the fit is perfect (bolt installed, nothing damaged) then you can push pretty damn hard on it. But if the fit is sloppy the wrench is going to be trashed. Most of us have seen this happen with a forged and hardened steel open-end wrench; doing it to an aluminum part is a bad joke by comparison. --Paul |

I didnt do any damage, but i didnt say go and jam up and down the
street for a couple fo hours, just enough untill the came off. I didnt go nuts. I will be buying a crank puller here sometime, just seemed to work for me, neither of my bikes cost more than $25, so if i did damage something, but thanks for the warning, maybe i will retire this method. |

That's also a great way to open up the tapered fittings in the arms and
put yourself in the market for some new cranks. IOW, I wouldn't recommend it! May you have the wind at your back. And a really low gear for the hills! Chris Chris'Z Corner "The Website for the Common Bicyclist": http://www.geocities.com/czcorner |
