Easy Repair
The replacement of this part is straight forward and should take no more than 5 minutes as long as you have a small enough punch to knock out the pins that hold the trigger assembly together. Once installed the finish nailed operated perfectly. The shipment was delayed even though I paid for expedited service, but this was no fault of eReolacentparts. They promptly refunded my expedited charge after reaching out to customer service. The response was much faster than advertised, kudos to their customer service team.

Solved the problem
A Dewalt nail gun recently failed to fire nails. It seemed as though there was a reduction of volume to properly fire. I removed the firing cylinder and all of the o-rings seemed fine. I removed the trigger and discovered that the interior o-ring was deformed. I could have replaced the o-ring but it was more efficient to replace the entire trigger.

1. Took out the hinge pin for the trigger, saved the rubber retainer washer that holds the pin.
2. Set the trigger and spring aside.
3. Use a straight punch OR take a nail the diameter of the two spring pins that hold the valve in place, grind the end of the nail flat. Gently tap the two pins out, NOTE they are different lengt

4. Pull the trigger valve assembly out of the gun frame, Mine separated and required long nose pliers to pull the second half of the assembly out.
5. Inspect the empty hole for dirt and or debris, clean as needed.
6. Take the new valve assembly and use a light touch of Vaseline on the two rubber \"O\" rings just to help them insert in the frame. Caution do not block the air gaps in the valve system, just a light touch of lube to help assembly.
7. Orient the gray safety lever in the correct position and insert the valve assembly into the gun frame. align the two notches so the spring pins will slide in place.
8. Insert the spring pins Long and Short in the correct holes, tap them in until evenly seated. (same amount showing on both sides)
9. Place the trigger and spring back into position and push the hinge pin in making sure it engages the safety bar (this should not have moved but if it did make sure it is back where it belongs so the hinge pin keeps it in place).
10. Place the retaining rubber washer on the end of the hinge pin and you\'re back in business

Nailer was shooting air out of the trigger and not nailing.
Took a small nail and a hammer to push out the 2 pins that hold the trigger assembly in place.
Pulled trigger out, slid the new trigger in and pushed the 2 pins back in and DONE. Works like new.
Remove one pin above trigger pull trigger out then punch out two roll pins holding trigger valve. Pull out valve and install new and reinstall everything
Removed trigger, punched both pins out, removed old valve, installed new valve, installed pins
released latch,removed screw from contact tip,installed new contact tip

Nail gun quit firing. Large amount of air coming out of trigger valve
Removed trigger and pins holding in the trigger valve in the gun. Removed trigger valve and replaced with new one with a little lithium grease add to it. Put pins back in and then the trigger. Worked just fine after this repair.
1. Removed the trigger and damaged trigger valve assembly (watched online video).
2. Installed new trigger valve assembly.
3. Installed two pins to hold the trigger valve assembly in place.
4. Installed the trigger.
5. Connected air hose, tested it and my nailer is back in operation.
I tapped out the 2 roll pins with the hammer and a long shank punch, I think it might have been a 1/8 or just a tad bit smaller, used the dental pick to pry the grommet off the trigger pivot pin. Removed the pivot pin and the trigger then pulled out one part of the trigger valve, it had separated and part of it was still down inside. I us
... Read moreed the pick to remove it, all the pieces came out pretty easy. Placed the new trigger valve in, started to insert the roll pins but the valve assembly wasn\'t seated far enough, it kind of snapped into place when I applied a little more pressure. Replaced the roll pins and the trigger pivot pin, this was a little tricky at first, then I realized I needed to depress the trigger plunger to get the thin wire safety spring back into place, popped on the grommet and it was done.

Air was leaking around the trigger and thus the nail gun wouldn\'t fire.
After finding an exploded diagram online of the nail gun, I was able to see how the trigger assembly was removed from the body of the gun by knocking out 3 small pins with a hammer and small nail. Once the assembly was out, I noticed 2 small O-rings appeared to be damaged. I ordered a replacement trigger assembly and slipped it back into
