Reassemble and Test for Leaks

all right so now once you've get the packing in there and your um packing nut has tightened down not over tighten we're going to install our needle now another step just to get that needle to slide in there easily easily or a little bit more easy and to lube the packing i'm just going to rub down my needle if you've got some piston lube so tighten piston lube i can just rub some of that on my needle it's going to make it glide in lubricate that teflon packing so i'm going to stick my needle back in it's going to glide right in now i can take my cap it's going to screw my cap right back down gonna squeeze my trigger reinstall my gun put everything back together put on your nozzle gonna tighten this down when you're doing this it's a good thing to just you know completely tear your gun apart clean this thing up a hundred percent now it's ready to go now a critical step in this process i'm going to hook my hvop gun up now i'm going to hook it up to either water or product and i'm going to begin spraying it at a low pressure and watch to make sure nothing's leaking out of this packing nut right here if you have anything leaking out of this packing nut what we're going to want to do is take your 10 inch 10 millimeter wrench i'm going to tighten it a quarter turn just a quarter turn and then i'm going to spray again under pressure and if the leakiness stopped then you would want to stop right there if it continues to leak then you're going to want to take your 10 millimeter wrench again and tighten it another quarter turn and you're going to keep doing that quarter turn process until it stops leaking and then that's when your packing is tight enough a lot of times once you tighten it down just initially just not very tight just enough to seat that packing it's not going to leak but that's how you replace the teflon packing and an hbo2b gun a um an hvlp gun a maximum elite or a maximum two gun from titan very simple process it's only going to take you about 10 minutes these packings are
