Review on 💪 Ingersoll Rand Air Hammer 114GQC: Powerful Pneumatic Tool for Efficient Job Performance by Dwight Tim

can help. I've had IR equipment before and the quality has always been high, but not with this 114GQC pneumatic hammer. This model has some very real problems. 1. Mechanical dirt mixed with oil forms a type of deposit in and around the air valve/throttle piston assembly. Wrong gas rubber seat.3. Rubber grip cap/grip that twists. Number 3 is just annoying and was solved by removing it, but number 2 is definitely a deal breaker. more on that later. #1 is why other bad reviews have complained about worn o-rings. I bled the 114GQC and replaced the o-rings but the root problem (number 2) was still preventing the tool from working. When triggered, the tool hissed, new out of the box, for just a few seconds and then stopped. With every pull of the trigger, all this will happen. I have found that the trigger (item 11 on the diagram) cannot depress the throttle piston assembly (item 3 on the diagram), only a few millimeters. After removing the inlet bushing (item 7 on the diagram) and then the throttle ball seat (item 2 on the diagram), the trigger and throttle piston assembly was finally able to push the throttle ball (item 5 on the diagram) sufficiently for the 114GQC to run fully . The solution is to cut off about 2mm of the base/bottom (non-rounded ball seat) of the throttle ball rubber seat (part 2 in the picture). I did this with a single blade razor on a glass surface, taking my time and being careful not to cut myself or ruin the throttle body. Why stress? I had to because I was stuck at work and needed to get work done. The good news was I finally had the air hammer I needed and it has been working great for a while.
