Question about Ingersoll Rand 3/4" Super Duty Extended Anvil Air Impact Wrench
I use IR 261 guns. We tighten 1000 1/2" bolts a day per gun. I cannot keep a gun running for more than a few days before the vanes stick into the rotor and you can't get the gun to start. It just puffs air. I'm running 100-120 psi, filter, oiler. I have put in new vanes, have run them dry, wet, very wet, and have tried every combination possible. We even buy new guns that only last a few weeks before they start doing the same thing. I have also had the same problem with 271 guns. I'm at my wits end!
NOT exactly a solution, but may help you with your problem: I'm also a Owner of a 261 ( In fact 90% 0f all my Air Tools are IR) that I used everyday when I was working on Terex Equipment & EMD Locomotives. I "Upgraded" the Major Parts inside my Gun to the "Industrial Line" rather than the Automotive Parts since the 261 is classified as a Automotive Tool..and Installing an Adjustable Regulator on the Gun Helped a Lot too...by "tweeking" my Gun out, I was Pumping almost as much torque as some of the 1" Guns...
FYI: Don't Over Oil as the Oil will absorb into the Vanes, causing them to Expand in thickness "Permanently"...just 2-3 drops of a Hi-Grade Air Tool Oil before starting the Day is enough...sounds to me like your Picking up some contamination someplace??
