What happens here

Next, use the 5/8 inch box wrench to unscrew and remove the spring housing from the back of the gun. Once the housing is off, carefully pull out the old spring and the small retainer. These old parts will be replaced with new ones from the kit. The needle assembly is now exposed. To remove it, use the 9/32 inch socket and crescent wrench to loosen the nut on the side of the gun that secures the pin running through the trigger. After loosening, remove the pin. If the old needle assembly is stuck, pliers can be used to gently pull it out.

going to take off the back of the gun, the spring housing. Loosen that up with our 5/8 inch box wrench. Just unscrew the back of this gun here. And going to set that aside. Pull out the spring. You're going to be getting a new spring with your packing kit. And then there's the back. You don't want to lose this. And then now your needle assembly is exposed. You just got to take off the pin that goes through the trigger cuz that's what keeps the needle assembly locked in there. So I take my 930 32 wrench and my crescent wrench. I'm just going to un loosen that the bolt on the opposite side of the pan. Now that pin will come out and you're going to get a new pin assembly with the packing kit. Now this packing kit, if you pull it, your needle assembly will pop right out.
