I bought an Ingersoll-Rand Air impact. (2135QTIMAX) This gun claims to have 780 lbs of torque in reverse. I have a 5.4 SCFM 15 gallon Air compressor and the regulator is set at 90 PSI. http://www.dewalt.com/tools/compress...ic-d55168.aspx

This is my first air impact I have always done things by hand. Am I wrong but I figured this would have little trouble removing lugs nuts of a Jeep Liberty. I couldn't get this impact to break them I had to do it by hand with a breaker bar.

The only thing I can think of that might be causing a problem is maybe my 1/4 hose. I found one site that said 3/8's hosed but I found nothing coming directly from Ingersoll-Rand.

Thank you

 

the lug nuts probably was over tighten
i had that problem many times with lug nuts

 

a bigger hose will help...but yeah, lots of people just wind lug nuts on waaaay too tight.

 

1/4 line is the problem that impact requires lots of CFM also the 90psi didnt help it breath either. Turn the air up and get a 3/8 hose it will bring that thing to life.

 

What you guys are saying makes sense. I went up and bought 50' of 3/8 hose. I have been doing some reading and it seems it was a likely problem. I played with it a little bit but it was getting dark and cold so I put it off until tomorrow.

C5R it says the Max PSI is 90 but that seems low to me. I even turned it down from 100 where I run it for my nail guns.

Thanks for the input guys

 

yes thats what they say but higher air pressure wont hurt. race teams run there tools on 200+ psi off co2 and dont have problems. the air pressure is not a concern. also the pressure will help for a lack of cfm.

 

Cool. Seemed to me that 90 Psi is low. Thanks for the help.

 

I run my tools at 90 psi without any issues.

 

problem is you bought the Q.. the q means quiet which also means lameeeee. They quiet it down but also decrease performance. I tried it and it would even break strut bolts loose. Buy the regular 2135

 

not true. my buddy has the same impact and he takes of dually lugs with no problems.

crank that bitch to 140. thats what the shop lines at my work run.

 

I will crank it up and give it a run next weekend. Thanks for all the advice.
