The trigger would no longer worked
I punched out the trigger roll pin with a roll pin punch of the correct diameter
Removed the trigger and plunger assembly after loosening the trigger valve nut with adjustable pliers gripping the outside of the nut since I didn't have a spanner type tool that would fit the slot in the top of the nut
Replaced the urethane ball, trigger plunger and installed the new O-rings and valve packing
Re-installed the plunger assembly and trigger and tapped the roll pin back in place
Put the air hose on the tool and successfully fired about 7 16d nails into a piece of wood
Works like new again

I fixed my framing nailer
I bought a angle frame nailer for a dollar in a yard sale. I was told it had a bad air leak. I took it apart and ordered replacement O-rings and gaskets. Everything fit well. I found that one gasket was missing from under the trigger. It has to seal air loss after the little ball reseats after firing. It worked! Thanks I don't know where else I might have found such parts and fast service.
