Using truck as air compressor

Even if governor cut off is set to 125? My truck supplies enough air to loosen up 5-6 nuts before having to refill air tank for the rest of the wheel.

 

I've seen a guy trying to get lugs off with 1in gun, and air from the truck. No go. Don't know what size of hose he was using, but the gun clearly didn't get enough air

 

Most likely tried to supply the air directly from gladhand line? Pneumatic 1in impact guns need a lot of volume, AND constant high flow of air at least 90PSI to operate properly.

 

I've seen them and heard great reviews.

 

If you’re going to use the truck air , I’d consider a portable 5-7 gallon tank , with a half inch hose , at the wheel with the impact tool, and feed the tank with the gladhands .

Yoire still gonna be waiting on the tank to refill but that gets you the volume you need , in short bursts .
As for doing more than one wheel, you should be at a shop ..
Or at least at your house with the proper tools .

why would you be removing 40 Lug nuts for one flat tire ?

i always carried a mounted spare , and a Jack etc
But always called road service first and if they could come swap it on for me in less than an hour I just paid them to do it .

 

I have regrooved tires as well
But it was much easier for me to just Jack up the axle so I could spin the tire as I grooved it .

 

Don't you have air suspensions? Undo the leveling valve and lift the frame with it.

 

Ahhhh, so THATS my problem, didnt have mounted spare...

Battery is still full after reinstallation btw, torque wrench not pictured

I saved 6 hrs and 20$ by having 1000$ of tools in the truck... but the loves still charged me 656$ for the new steer + mount/dismount...
