Not WW: Automotive impact wrench

[Stray_shot]

So after buying all this stuff to take off the trailer wheels (gun, sockets) it didn't have enough muscle. I assume its the gun, not the compressor, but open to your opinions on that (PC 6 gal 135hp pancake). I ended up doing it the old fashioned way, using the little bitty half of a tire iron my Subaru came with.

Its not worth returning the stuff because its a) HF and b) too heavy. I wonder if I torque them back on again later to correct tolerances will the gun be able to take them off next year or not. OR do I need a more powerful gun? Now that I have the sockets, I have to have a gun to drive them, right?!

A penny wiser, a dollar poorer.

What size hose are you using and what kind of fitting to connect the gun? The first impact I ever got I thought was just too weak. When I returned it and bought a second, better brand that did the same thing I started looking. If you use a little 1/4" line with those narrow i.d. quick connects, you'll never get enough air for any gun to work well enough. They make connectors they call "automotive" type that has a much bigger i.d. than the "standard" ones you usually see included with hose kits. Also 3/8" i.d. hose is a minimum, 1/2" preferable. Of course, if you run your pressure at 150-200 psi, you can get around some of these limitations...

Thanks guys, I will have to look around for automotive connector I guess, as I am using quick connectors right now. The hose is 3/8" (I think, not looking at it right now)... hmmmm actually where is the measurement taken on the inside hole or the outside hose?

3/8" i.d. == inside diameter.

If you're just going to do this job ocassionally, and the QCs are throttling the air, don't use quick connects. Just plumb the hose to the compressor and to the tool with 1/4" NPT fittings with teflon tape and a wrench.

the tool and the hose probably already have 1/4" NPT (tapered) fittings, the hose typically have males and tools have females. No telling which sex you compressor will have after taking off the QC but F-F bushings are cheap and easily available, your air accessory kits usually come with M-M and F-F couplings.

BTW, 1/4" NPT fittings, the 1/4" measure has nothing to do with the inside diameter or anything else you care to imagine. I used to know but I forgot. The thru-hole diameter is at least 3/8" or more.
