This was what it needed
Just needed a little force to snap it in place. Would be nice if PC would offer the little seal needed instead of overcharging for a full assembly.

Porter Cable Trigger Value Assembly
I ordered this part on a Wednesday and it arrived on the following Saturday. It was exactly what I ordered and took me about 15 minutes to replace the old one. My PC nail gun is working perfect again.

The correct part the first time
I have ordered parts from you before and keep returning because the pictures and diagrams help define the part that I don't have a part number for.

This job was so easy, the hardest part was removing the old trigger valve assy. At first I was intimidated by the task at hand, but when you follow the steps below it is simple.
1... remove small roll pin from trigger with a punch pin or use the head of a medium size finnish nail (tapping the point with hammer until pin moves). Ther
... Read moree will be a small plastic o ring , do not destroy this you will need it.
2... remove trigger and set aside with pin and small plastic retaining o ring from step one.
3... tap out the two roll pins that hold the trigger valve assy in place and set asside. My gun had one pin longer than the other.
4... wrap a heavy cloth or small towel around your hand and place it in front of the trigger valve and hook the gun up to the air source.
The valve will pop out fast and hard, so be ready.
Replacement steps...
1... place new trigger valve assy in the gun. Be sure to line up the slots for the roll pins.
2... tap longer roll pin into the thicker part of the gun, and the smaller pin in next. There was no o ring for theese pins.
3... place trigger in gun as it came out, making sure to place wire spring over trigger pin.
4... tap in roll pin through gun trigger and back out through gun.
5... place small plastic o ring on pin.
6... place a couple drops of air tool oil in the air inlet of gun and connect air source. You should be good to go.
It probably took me longer to write these steps than it did to do the job.

The key to the repair is removing the spiral pins and the small pin (held by rubber washer) on the trigger. The use of a small punch simplifies the repair. Once the 3 pins are removed the trigger assembly pulls out with some pressure. The reassembly is a matter of lining up the pins and trigger assembly and pressing the pins back in pl
