Air Gun
The parts diagram was difficult to follow and the replacement parts I ordered were incorrect. I wasted my money as I spent half the cost of a new air gun.

Removed top cover of the Porter Cable finishing nailer and removed the cylinder that houses the driver rod.

Recommend about 80-85 psi when operating brad and finish nailers.
