I dont even think my torque wrench setting goes up that high. Lee [Reply]   [No Email]

I have complete confidence that it is tight enough. That is exactly what a high dollar torque wrench is doing when you set it to click at 100 lb-ft.

Torque is torque - friction has nothing to do with it. A 150# man on the end of a 3' bar produces exactly 450 lb-ft of torque. Jumping on the bar simply produces more than 450 lb-ft of torque becasue you are using gravity to "increase" your static weight (force) with an acceleration force. Friction enters the picture when we try to use torque as an indirect measure of the clamping force (tension) created in a threaded fastener as we tighten it. That friction varies with the materilas the fasteners are made from and the condition of the threads (oiled, greased. plated. etc). All of those factors are already included by the engineers in the 450 lb-ft specification for tightening that nut. Applying a greater torque simply produces a tension greater than the engineers wanted. TOH [Reply]  [No Email]

I put a rod between the lugs for the wheels and braced it against the ground when I tightened mine. Gerard [Reply]  [No Email]

Look at yer FO-4. And YES, 450ft/lbs BEFORE you put the snap-ring on the outside of the BIG NUT. Iff'n yer really sphincterly challenged, you can RENT a 3/4"-drive torque wrench with 1-15/16 socket. And NO, you don't want to buy a 600ft/lb 3/4"-drive torque wrench. ........the tite Dell [Reply]  [No Email]
