Lug nut torque

[Rlates]

All, I had new tires put on and want to check the lugs before we go on a trip. Does anyone know the torque for the lugs on a 2020 295RL??

This is a pretty good video that explains the whole process.

Keystone owner's manual page 25.

Pretty much another almost useless Keystone owners manual - too generic!
As the OP is asking about the torque, they probably are not aware of the stud size (1/2" not 9/16) and the different torque value for each (1/2" is 110-120 ft/lbs vs the 9/16 at 140-150 ft/lbs). Then there is the "Follow the appropriate star pattern sequence." instruction. But what is the "appropriate star pattern sequence."???

This isn’t exactly what the OP was asking. If you need a torque wrench Harbor Freight has a great one. 50 to 250 pound feet and $110 versus Snap-On $440. I’ve saw two good test and the Harbor Freight is more accurate and more consistent than the Snap-On. Of course you could get a $20 one that will work just fine for your camper.

Did you read the owner's manual? They give torque values for both 1/2" & 9/16" studs.

Did you read my post? Yes the manual gives torque values for 1/2" and 9/16. But the OP probably doesn't know their stud size. Plus leaving out the pattern to use when torquing is a mistake. As I said, the generic manual is useless if you don't know all the pieces parts you need to do the job.

Okay since I work in support I am a RTM kind of response guy. Yes the manual give the torque specs, but if you are going to sent them to the manual tell them what stud sizes they have.

Some are better mechanics than others. If not sure on how to apply the printed information it would be best to leave it to someone that has the experience. I'm pretty sure that if I was writing such manuals I would be providing information that would require some degree of common mechanical knowledge by the reader to apply it.

The nut torqueing procedure and star pattern is on page #27. If a person does not know how to determine the difference between 1/2" and 9/16" they should seriously consider finding someone that does because they are out of their comfort zone.

Now that's funny (and true).

In general, if the rig has drum brakes they are 1/2 inch and if disk brakes then 9/16. A 295 RL which is the smallest MHC made in 2020 will have 1/2 inch and should be tightened to 120 ft lbs.

Thank you

Then there is “dry torque” vs “wet torque”.
Discuss.

What kind of wet? This might be a debate or not.

[Ram-X]

I torque the lugs to 110 ft pounds and there is 8 lugs per wheel

No Debate.. Clean and Dry torque is just that... clean and dry.. no oil, grease or "finger" oil....
Wet torque or lubricated torque gets more complicated in that each type of oil, grease or lubricant has it's own lubricity factor. This is a measure of its ability to lubricate (reduce friction).. So, a true wet torque value must specify the exact lubricant to be utilized.
BTW, for reference, I spent 40 years in the fastener industry, teaching proper fastener utilization.

Interesting to note that on the video, they say that only the Cambridge model should be torqued to 150! Since the video is from 2010, perhaps the info is not quite up to date?
They do mention the different stud sizes, but would be a bit confusing to an inexperienced owner in the explanation...
Overall, helpful info though!

Here is a handy recommended torque calculator for use on any bolt/nut combination. Also shows “wet” and “dry” torque. I always use wet torque on any bolts/nuts I might ever want to remove in the future, but that’s just me.

The real issue here is, what is the grade of the wheel studs? And what is the recommended torque determined by the wheel and axle manufacturers? Also, torque values are never given as a wet value on lug nuts. The torque for the lug nuts on Dexter and Lippert axle lug nuts is 120 ft lbs. any much more than that and you risk over torquing the nuts which can cause the wheel studs to break.
