Disassemble Front Diffuser

take a crescent wrench and we're going to unscrew the front diffuser off this gun. begin unscrewing it. Once it loosens up, it actually should just thread off by hand fairly easily. And now I've got the diffuser. And there's two parts inside this diffuser. They're going to come out. And there's the seat for the needle. And there's a little tiny nylon washer in there. Now the needle is exposed front and back.
