How do you measure output torque on this if you need to torque something to, say, 200 lbft?

It's a 3 to 1 multiplier, so to get 200 ... set torque wrench to 75 . 75x3 = 225 - a 10% loss you would be with 5 ft lbs

what is the wa!rranty on this? Contacted amazon and never heard back.

I have no idea. No paperwork came with the tool.

Can anyone tell me the thickness of the head? From the face of the 1/2 drive input to the very edge of the 3/4 drive output?

The distance from the face of the 1/2" in put to 3/4" output is 3 3/8"

can I use it to loosen seized nuts at 1000 ft of torque?

It multiplies the torque you apply to it by about 3x. If you can apply 350 lb-ft of torque then you can apply 1100 lb-ft to remove bolts.

Wrong packaging

No manual, spair O ring is for the 3/4 input to 1’’ output and the red box is big, hard to rotate. I opened the tool and apply grease to the gears inside…

Quality torque multiplier

I bought this torque multiplier based on good online reviews, and while I haven't used it yet, it looks and feels every bit as good as I expected. Next time I need to remove/replace tractor wheel nuts for example, I know it's there in the toolkit. I was always wary of using long breaker bars!
