If I have a wrench 24 inches from the nut to the pull point on the wrench. If I hang my total dead weight of 300 lbs from that wrench what torque would it apply? This is on a packing gland on a hyd cylinder, all threads and seals are oiled well. Just curious to know.

Cinderblock wisdom from the past says to tighten a headbolt until it breaks and then back off half a turn.

I have had that ability in the past many times. As my senior years approach it seems to allude me.

300 lbs 2' from center should be 600 ft lbs torque, if I remember my math right...

That's how I recalled it as well but my memory is unreliable at times. Thanks

I have a "machinery's handbook" that explains all of that stuff, but it takes me about 2 days to find what I am looking for.

I worked with an old guy many years back who always said, go till it squeaks then just a little more
That was putting wheels on the big trucks.

As tight as you can get it and then just a little bit more.
