Tourque for wheels on 763 and 743

[cmb7684]

On my car I always did the lug the old fashioned way with a 4 way wrench by hand. I have a few questions.

I going to buy an air impact set as its really a must IMO. I pushed for room in my garage so I hate to buy a larger compressor if I can avoid it. I have a pankcake compressor.

1. My question is how many pounds of tourque are required for the wheel lug nuts on the 763 and the 743?
2. Is my pancake compressor enough to run an impact wrench?
3. How much strength (torque rating) should by new impact wrench have?

I'm really just looking for something to change the wheels on my car and bobcat when needed.

The numbers i found was that its a 9/16 size stud and a rating chart suggests that 9/16 studs require 135-145 lbs of torque but I'm unsure if that is correct.

I generally do mine up with a rattle gun, but then go over them with a bar, just to be sure. I don't use a torque wrench, i just haul on them pretty good.
I'm sure your compressor would handle it, but it may take time for it to catch up is all. You may get a few done then have to wait for it to build up pressure again.It all depends on what size reserve tank you have.

Spec is torque to 160 and check at 150. Personally I torque them since 90% of the time I'm using a cordless impact I don't trust them to always get them tight. That said, just get them tight, you're not going to hurt anything over tightening them, unless you're the Hulk.

Maybe I'm over thinking it or aybe im postponign getting off my butt and doing it LOL. I went and looked at SEARS today at their Air impact wrenches. None of them cheap t high dollar have a torque setting on them.

I'm not trying to be the hulk but their cheapest one said it had 360lbs of torque. Double what I need and just dont want to break a stud by using the impact tool.
The guy at sears said he thinks mechanics use something called a torque stick to put on their air tools to keep the torque correct.

I have had to use my 3/4" impact rated for 1200 lbs to remove some lugnuts, you're not going to break studs. The only thing that breaks studs are loose lugnuts.

When working on cars, wheel torque is much more important because uneven torquing can warp brake rotors. For cars I use torque sticks, but on a skidsteer, good and tight is good. Get a good mid level impact good for 500 lbs ft and you will be good to go.

My 1/2" gun is rated 380 ft/.lbs and I run shop air at 150 and hammer them down until they stop moving. It would have to be a really heavy duty 1/2" impact to break a stud. Also with 8 bolts on a 8" circle and only a 10 16.5 tire they seldom have any trouble coming loose. The same bolt circle is used on larger tire combos too. I run tracks on mine and have never had a wheel come loose.
Make sure there is no dirt between the wheel and the axel and the studs are not banged up and you should have no trouble.

Thank you all for the input. I havent swapped my wheels over yet but I did use the starting fluid tire mount trick on all 4 and it worked like a champ! I now have bought myself some time to swap the tires.

A very goo impact is the IR 2135 TImax. light weight and has lots of torque.
