How to measure high torque values?

So VERY true! 😎

@DumbStudent - a student, or anyone, is Dumb when “they know not and they know not that they know not”
It appears to me that you do not qualify as Dumb.

at the risk of being too technical, a person is dumb when they cannot speak. That's the direct meaning of the word - just like an ass is a donkey.

but most people don't know what they don't know 😉 especially me!

Ya, but at least you know that you don't know what you don't know...... And that was part of @CWret's point.

OT:

40+ years ago we gave a vendor a copy of a spec (ANSI F2.1, Food & Beverage Equipment Sanitary Construction - last updated sometime in the 80’s and no longer “available”) that had been referenced in an RFP. He said, “That which I do not know for me does not exist” (IIRC he was from the Netherlands) and went on the say that now that they were aware of the requirements they would revise their proposal accordingly.

This company and many others was oblivious to information that was critical to what one of their largest customers’ needs, and didn’t think that requirements differed customer to customer, whereas it was obvious to us.

Not quite the same thing as having some knowledge (such as proper torquing a fastener was important) but not knowing all of the factors that go into the procedure. However, the supplier did know that their equipment needed to meet sanitary requirements, just didn’t know how those standards may differ (and didn’t seem concerned about that).

Don’t just torque that assembly without cleaning the threads first.
Recommend torque specs are for clean, corrosion free, non lubricated threads.

Agreed except for nuts with a skirt that spins. Or if you're using loctite. Use thread chasers not taps/dies.

At least that's how I was taught

I assume you are talking about hub centric, flat faced lug nuts with the integrated washer. Those must be lubricated between the nut and the washer, but not the threads. I do lubricate the threads, as I do with all lug nuts. I subtract 25% or so on most. Experience and knowing my guns and pressures helps out a lot here.

Most thread lockers are not an actual lubricant in high pressure applications, and actually produce less clamping force for the same torque input. For these applications, I don't typically change my torque value.

Just out of curiosity, do you have any experience with "river wear" on steers? The inside and outside get bald spots yet the middle stays flat. I can take a pic if that makes no sense

 

[Darren]

Where the outer ribs wear lower on steer tires? thats kind of normal actually. We see it a lot. If you are talking about cupping, then thats a different story

 

[Chicken lights]

Ya, more like cupping

 

[Darren]

Thats cupping. Alignment, bushings, kingpins or shocks. Check wheelbase side to side if all else checks out. Could be a misaligned drive(s) too. Something is usually out of whack .

 

[Chicken lights]

The tire shop said even pulling a trailer with bad alignment can cause it- the trucks fighting to pull straight but the trailers pulling it out of alignment

 

[Darren]

That actually is possible too. I deal with mostly straight trucks these days, but have seen cockeyed axle slides and actually pulled one once. Going down the road, you could read the writing on the side of the trailer in the mirror.

I thought all thread lubing such as with "coppercoat" was outlawed years ago, at least it was in Ab.. I think it was country wide tho as a directive in the "National Transport Safety Code" that every truck owner has to be a member to.

Sorry to tell you Chicken but that steering tire cupping is a bottomless rabbit hole to try to correct. I had 3 trucks, one cupped ferociously, one cupped slightly and on never cupped at all. The really bad one, I tried front wheel alignments, Laser frame straightening, different tire manuf, even those expensive rotating floating ball bearing wheel balancers that are available ( they did improve the ride & eliminated 90% of the truck vibration but tires still cupped). I finally resigned myself to purchasing new steering tires every spring and getting a few more miles out of the "cups" on my trailers.
