Torque Wrench Calibration

snip In the Air Farce we were supposed to click the break type torque wrench three times at the lowest setting before using it. This was supposed to spread the lubrication inside. I like the idea of taking the wrench to a shop to check calibration. Having said that, in my first shop in the USAF we calibrated torque wrenches so I may be a tad biased. The machine we used was huge and probably weighed close to a ton. Torque wrenches in the USAF are periodically calibrated, I forget the cycle, and taken in for calibration if dropped or abused. snip Dan, U.S. Air Force, retired Heck, Dan, in the Air Force there was an alternate torque measuring system that didn't even require a torque wrench. (PMEL calibrated, of course) Simply "strip" it and back off one half turn. Farm boys from Georgia taught me that. Old Chief Lynn We used the "tighten it until it breaks, then back off a half turn" and the "finger tight, plus a quarter turn" methods. QC wasn't fond of the response "two clicks of the left elbow" when we were asked what the proper torque was. Wasn't the -2 T.O. series issued to sit on or to protect ones knees on a B-4 stand? Not that I ever did that, you understand, but there was talk. Dan, U.S. Air Force, retired |

Never realized the -2 was so versatile! Old Chief Lynn |

Old Chief Lynn Hey don't forget the proper torque on the propellor retaining nut on the 4360 was "All you can with both hands on the Cheater Bar, then a 1/4 turn more". Note proper Cheater Bar was 6' long. Stu Fields B-36 engine change crew. |

SAE = 1 3/4 grunts Metric = Gutentieght |
