I am removing the frame, and it just so happens that one of the bolts that holds on the frame lines up with the belt. So i need to loosen the belt, i do not need to remove the rear wheel. I read in the manual that if i loosen the axle the belt should loose tension, and that should be enough for me to get to the bolt i need to. I have the bike jacked up, i loosened the rear axle pinch bolt. I understand that the rear axle is reverse threaded, so clockwise will loosen it. I got the adapter out of the tool kit, and i can't get the axle to budge. I am a big guy, and i am putting a ton of force on it, and it won't move. What should i do? |

Did you loosen the pinch bolt? |

I got it! I just had to pull out my 2.5 ft torque wrench to get it to loosen up. |

Congratulations! I was just going to make that suggestion. My Ulysses has a similar setup for the back wheel and it took some effort to get the axle loose to remove the wheel. |

Sorry Dk, didnt see that you loosened the pinch bolt was still half asleep.. |

I recommend you put a ton of antisieze on the threads to make it easier to remove next time. |

Why would a torque wrench help on loosening something? Or did you mean breaker bar? |

I sure hope that you didn't use a torque wrench to break the axle free |

on my first attempt, i was using a regular 1/2 inch socket wrench that is about 10 inches long. It wouldn't budge the axle, so i pulled out a 2.5 foot torque wrench and set it to 250 ft-lbs and it got the axle spinning. |

A torque wrench only MEASURES the torque in lb-ft, etc, it doesn't provide any. I guess if that's the longest wrench you've got then it would provide more leverage than anything else you have but I'd think that would cause damage to it if you're using it for the exact opposite that it is intended. Get a cheap 1/2" breaker bar. |

There is absolutely nothing wrong with using a torque wrench in the manner he did. ac |

You're not supposed to use a torque wrench for loosening bolts. Period. |

If you set the torque wrench up to 250 ft lbs and used it as a breaker bar even if you only used say 175 ft lbs to break it free you were loading up the springs and mechanisms inside the wrench and when the axle broke free it instantly unloaded the wrench. You may have got lucky and didn't damage it this time but using a torque wrench in this manner will cause it to loose calibration. |

I don't think you could throw the calibration off. The calibration on most click type torque wrenches is done by adjusting the spring preload in relation to the scale using a jam nut setup and the handle. With the wrench set to its "max" the spring force would be at its highest. Even with the axle breaking loose "instantly" I don't see how this could effect the calibration. As long as he stayed below the max torque, the pawl would remain inline with the top of the spring and not a whole lot could move. http://www.tegger.com/hondafaq/torque_wrench/index .html ac |

Avc, One of the links included in the link you sent is this pdf: http://www.motor.com/magazine/pdfs/022002_08.pdf In the article it says this: Never use a torque wrench as a breaker bar for loosening fasteners. Don’t try to tighten a fastener beyond the range of the wrench and never use a “cheater pipe” on a torque wrench. |

I see that. Trying to figure out "why". ac |

http://www.tomorrowstechnician.com/Article/621/get ting_tight_with_torque_wrenches.aspx "Most experts also advise against using a torque wrench to break loose fasteners because the sudden shock when the fastener breaks free may affect calibration." -------------------- Why would you use a $80+ torque wrench to break something loose when you can use a $10 breaker bar? Anyway, I won't use mine for anything but tightening/torquing per specs. (Message edited by Kidder on July 05, 2010) |

i didn't know that i wasn't supposed to use a torque wrench to loosen a bolt. I guess i will have to pick up a breaker bar. It is a brand new torque wrench, so hopefully that one time didn't mess up the calibration. |

I didn't say a $10 breaker bar wasn't the best solution...I just meant I wouldn't throw out the torque wrench now that he has used it to break the axle loose. ac |

i just use a car wheel nut bar like this. but then again i also anti seize my nuts, so i dont need any force on them |

Use a heavy impact, borrow a buddies or something! The electric will do the job, but I prefer air. |

mtch, my dealer changed the wheel, so they torqued the axle. i'm not sure if they used anti seize, but i hope they did. (Message edited by dktechguy112 on July 07, 2010) |

You may have got lucky and didn't damage it this time but using a torque wrench in this manner will cause it to loose calibration. thats the most ridiculous thing ive heard all day.. you will not ruin your torque wrench by loosening bolts with it. try torquing down a 32 bolt beadlock wheel. you will be torquing those bolts down for the final torque sequence at over 3 bolts per second, and i assure you that there is more sudden force applied on the springs inside of the wrench than you could ever do by breaking lose a bolt with one. what you are NOT supposed to do, however, is use continue adding pressure to a torque wrench after it clicks - that can damage the springs inside of it. |

I have 3 torque wrenches and . . . since I'm not as anal (nor required) about getting my personal ones calibrated and certified like the ones we use for electrical connections. . . I try to keep them in their cases, use them as intended and treat them with care. Beyond that . . . well . . I'm not sure anything on the bike needs a +/- 1 lb/ft accuracy. |

+1 on anti-seize, I put that sheist on everything. |

Do you need a left hand torque wrench for left hand threads? No, they work in both directions and only will suffer if you go beyond the setting. |

I don't think that any one made mention of left or right hand torque wrenches when using the wrench properly you are controlling the unloading of it no matter how fast you use it if you use it as a breaker bar you have no control of unloading it when the piece breaks free. |
