Changing the range of a torque wrench.  Angular use. Adjustment correction when using torque-wrench extensions.

This article explains how to use an ‘extension’ for the purpose of convenience (perhaps a hex or 12 point socket or an allen wrench or other tool won’t fit at the end of a torque wrench where you need it); or, perhaps you want to increase the range of a torque wrench.

This article explains how to use an extension for such as the Airheads U-joint flange bolts, where you simply cannot get a torque wrench without an extension to fit properly, due to the limited room between the bolt and the U-joint body.

Another usage might be that if you only have a 75 ftlb maximum indication torque wrench and need to tighten the wheel bolts on your Paralever bike to 105 ftlbs,  ….you can do it with an extension, and this article explains it.

Torque Wrench Discussion & Conversions

BMW made some serious mistakes many years ago in converting metric to English values in various of their publications. They admitted this. In BMW Motorcycle Dealer Bulletin (Vol II, No 23,  dated 3/1982) BMW SAID NOT TO USE ANY PUBLISHED BMW CONVERSIONS FOUND IN BRACKETS IMMEDIATELY BEHIND THE MILLIMETER FIGURES, IN ALL SERVICE LITERATURE, INCLUDING RIDERS MANUALS, SHOP MANUALS, etc.   This means that BMW meant for you to NOT USE published foot-pounds of torque, or any other torque value other than the metric.   You can almost always TRUST BMW’s figures in Nm….although I recommend less torque, for such as spark plugs; wheel preload, ATU nut, alternator rotor bolt, and a few other places, with some special cautions on the flywheel (clutch carrier) bolts.
