Dealing with counter-clockwise torque.[ILLUSTRATION OMITTED] Dear Editor, Most mechanics don't realize that torque wrenches are calibrated cal·i·brate tr.v. cal·i·brat·ed, cal·i·brat·ing, cal·i·brates 1. To check, adjust, or determine by comparison with a standard (the graduations of a quantitative measuring instrument): by TMDE TMDE Test, Measurement, & Diagnostic Equipment only in the clockwise direction. What makes that a problem is that some of the larger vehicles like the M939s and M977s require some wheel lugs to be torqued counterclockwise. As a result, the lugs may not be torqued correctly because the torque wrench may not give the correct reading. Disaster could follow. Please make mechanics aware of this. SFC SFC abbr. sergeant first class David Leach Vilseck, Germany Editor's note: You bet we will, Sergeant. Units that must torque counterclockwise with their torque wrenches should ask their TMDE folks to calibrate To adjust or bring into balance. Scanners, CRTs and similar peripherals may require periodic adjustment. Unlike digital devices, the electronic components within these analog devices may change from their original specification. See color calibration and tweak. their wrenches both clockwise and counterclockwise. When they're finished calibrating, TMDE will stick a red band with CW/CCW on the wrench showing that it has been calibrated in both directions. If a wrench doesn't have a red band on it, don't trust it for counterclockwise torqueing. If you have any questions about special calibration, contact TMDE's George Fox at (256) 955-0025, DSN DSN - Digital Switched Network 645-0025, or email: @conus.army.mil |
