Title: Torquing lug nuts
Post by: Falconguy on September 02, 2016, 03:34:13 pm
I went back to TCI to have the lug nuts re torqued after my tire installation. I "helped" the tech so I was right there as he did the hard part of this job. Surprisingly six of them were "loose" .ie. had some movement and two of those were what I considered very loose. Is this normal? Leaving soon for GrandVention and planning a stop en route to check one more time. This is the first time I have replaced tires so I'm looking for information.

Interesting thread. I wonder, A) how many of us know what the torque specs are on our different coaches? (B) Do tire stores have torque wrenches anymore, or is this something else we have to drag along to make sure the "pros" with their air guns do it right?  ???

On my coach the specs are on the lug nuts themselves and yes they used a torque wrench set to the mid point of the range specified. They did not run them down very tight with the air gun.

All the info you never knew, and some you don't need too....

Did he use some oil on the threads? Here is a picture of the page from the Alcoa manual that deals with hub piloted wheels. I am not sure what year or build number Foretravel started using this style, but our 99' has them.

As I was typing this reply, I see Stump posted a link to the PDF. It covers all styles of Alcoa wheels, but the picture below is specifically about the Hub piloted variety.

Yes, they did lubricate the nuts with motor oil. I inquired about torque seal on the nuts to have a visual reference but he said no, the only thing they were allowed to do was lube the lug nuts.

I do NOT have torque figures for oiled/lubed threads.  It will certainly be lower than for dry, which is what all the specs call for (clean, rust-free and dry).

Page 34 (5-2) in the file that stump posted shows the proper torque chart for both dry and lubed. Make sure of whether you have stud piloted or hub piloted as there is a big difference.

Reading the torques is confusing as dry torques are listed for stud piloted and below under the * it says to oil the first 2 threads of stud piloted studs and no torque value under the lubed column for stud piloted. Gland I have hub piloted it is clear.
