Anybody have or know somebody who has a torque wrench capable of measuring 600 ft-lbs?
I probably won't need to use it until after New Years and I'd be willing to come to them (within reason) since they cost $400+.

TIA,
Brandon
 
If you weigh 200lbs and have a 3ft breaker bar, you can put a strap on the end and hang from it (without jerking or bouncing) and produce 600ftlbs of torque.

Another similar way would be to strap the axle down (on a trailer for example), step onto a scale, record your weight, and pull up with 200lbs of force beyond what your weight is.
 
Yeah, I just tightened mine with a 3ft bar until I couldn't tighten anymore, then bumped it another couple of times with a 10lb sledge.

Someone paid attention in Statics class! :lol:

Or was that in Dynamics class?

I knew there was a reason it took me 12 years to graduate........

Statics, but really it's just understanding the units. No one uses Newton Meters because more people are familiar with a Fig Newton than an Isaac Newton.
 
This calculator was linked off the link I gave earlier. http://www.cncexpo.com/TorqueAdapter.aspx

For your case, use:

A=0 (angle of extension to the wrench--keep them straight)
E=48 (length of extension bar--however long you want)
L=18 (length of your torque wrench, from the drive head center, to center line of the grip)
D=600 (desired torque)

These numbers calc to setting torque wrench to 163.8ft-lb. Will vary depending on length of your wrench, etc.

I made my extension exactly 2x the length of my wrench (to center of grip)...that way there really isn't any math...if I want 300ft-lb, then I set wrench to 1/3 of that, 100ft-lb.
My wrench = 18", my adapter =36".
 
:beer: must have been asleep most of the day, I just learned something for the day!!:beer:

If I couldn't find one, I was just going to make a 7' breaker bar and pull 100lbs at the 6' mark with a big game scale. Haven't seen 200 on the scale in a while, 6'6" + a big ol' head soars past 200...didn't get the nickname/handle "Lurch" for nothing!

Probably a D60 upper kingpin.

Nice...that'll be a back-up plan, thanks!
 
I was going to suggest just that, but they all beat me to it. I've broken many a kingpin loose with a 3 foot jack handle and a regular 16oz ball peen hammer. Constant pressure on the handle and very small taps on the outside of the knuckle around the threads will pop it loose easily. I figure I can get it just as tight with the same bar. Especially if the axle is still bolted under the truck.

Problem here is the axle isn't under a truck...yet. I'll probably strap them down to my trailer deck when the time comes.

That didn't seem as corny of a post last night...must've been the beer talking.

I did mine in the floor. Used my feet to hold the other end while loosening/tightening. It stayed stable and gave me something to push against.
 
Found out that the shop manager at a fabrication house we deal with at work has one that will go to 1200ft-lbs! I'll be borrowing it if only to satisfy my curiosity of how massive that torque wrench is.

The handle is two metal circles that get clamped around Chuck Norris' testicles.

My thoughts exactly. If its like Mangler says, I don't think I'd borrow it after all...
