My trusty 392 is in need of a rebuild. Desperately. I get no power and everything feels loose when you pump it, its super accurate but if you don't have the punch you can't get very far. I think 90% of my problem is that the pivot link is so worn out that when it shifts its not pushing the piston down far enough? The video shows how much the link shifts on the pump arm. My other question is that will the pieces and parts in my cart from Mac1 possibly let my gun get to ten pumps with no issue? And are all the parts compatible with my gun? Also, do the rivets for the linkage require a special tool to install them? I have a regular pop rivet gun but that doesn't look like it will work. Sorry for my jumble of questions, and any advice is greatly appreciated.Here's the vid:
