Here's a real back-saver, a tool about the size of a 3/4" ratchet handle but when you input with a 1/2" drive (see my torque wrench), the output is multiplied over three-fold in 3/4" drive. Pictured is my loosening the wheel nuts on my '93 D350, break torque about 300lb-ft. Most of us can pull 100 lb-ft of torque on a wrench so with the torque multiplier the nut lets go. I had my torque wrench set at 100, and it would snap as the nut gave nearly every time. I broke the OEM wheel wrench so had a variety of rigs to do this job, including torching the nuts and having to jump on wrench handles. Now it's easy. The tool needs to be braced on something, the ground in this case, then just pop it off. The tool I got is made in Taiwan and shows "Williams Tool Co Ltd" but I imagine there are all manner of other makers of a system this useful. In the pix shown here, as I pull up on my torque wrench, the tool pushes downward against the snipe extension braced at the ground. Too easy!

I hope you don't plan on using that torque wrench to tighten anything critical. Snapping bolts loose is the worst thing you can do to a clicker or a dial torque wrench.

I do like the multiplier tho.

Not to dog you out or anything, but the same as he said... Torque wrenches should never be used to loosen.

Good tool, tho.

We use those all the time at work, handy units when you are torqueing things to 1800 ft-lbs. without a hytorq. The 18:1 are nice as they ratchet, so you don't have to take up the spring in the snipe on every pull.

I always add a dap of anti-seize to the threads before spinning the lug nuts back on and torquing them down to 144 ft/lbs.
I haven' had a seized lug nut since.

Same here. nothing like drilling or chieseling lug nuts off.

wow how tight are you putting them on????

and that torque wrench is probably as accurate as an impact gun now lol.

We had an 18-1 as well, handy tool for sure. I prefer the air removal method.

the torque wrench needed to put only 100 lb-ft into the multiplier so I don't think it was upset, .... like I said it snapped at the 100 lb setting as most of the wheel nuts let go. Good point made tho, ... I'd never thought about the accuracy of this thing til now, thanks

You can also stack the multipliers for to attain more torque.

I use them to loosen the lugs on BUDD wheels that were torqued to 450 FP when I would have to change them on the road, it was a lot easier than the 8' breaker bar.

Some of the heavy equipment needed to be torqued to 6000 foot-pounds and it is all done with multipliers.

Ever wonder how they tighten those huge nuts on bridges and in the basements of skyscrapers?

This company has them up to 75,000 lbs.ft

norbar makes some nice torque drives. some of our equipment uses 20 to 30 inch acme thread. 37000 lb-ft of torque comes in handy assembly.
then again, so does a little heat...
