THE RIGHT WAY! Repacking Your Airless Spraygun

Watch on YouTube

What happens here

The main front part of the gun is unscrewed, exposing the needle. The rear part of the gun is also unscrewed to reveal a spring. It is crucial to squeeze the trigger while unscrewing or screwing the front part to prevent scratching the internal ball of the needle mechanism, which can cause leaks. All removed parts should be placed into a small paint can or bucket to keep them organized.

Goal: Separate the main front and rear components of the spray gun, exposing the needle and spring.

Tools and materials

5/8 inch Wrench — For initial unscrewing of the rear section
Airless Spray Gun — The main item being disassembled
Empty Paint Can/Bucket — To hold disassembled parts for cleaning and organization

wrench 5/8 wrench so to start off we got the gun right here one of the most important things when putting the gun back together is squeezing this trigger when you're screwing this little mechanism on the front right back on otherwise you're going to scratch the ball that is see see that inside there it's a scratch it and then the gun won't leak so even when taking it off when I'm doing any repairs I always squeeze the trigger just for good habit and good measures and sometimes these things are on pretty tight but the first thing cut the trigger squeeze and this the trigger squeeze is really really important if you're just cleaning the gun and then putting it back together and not putting brand new packings but what I've noticed i've ever took in this gun apart to clean it and if it wasn't leaking before it's going to begin leave after you clean it one of the reasons why is the ball if you've used it for any period of time the the smooth ball the just a grit from the paint the abrasiveness of the paint will eventually wear it grooves and that ball will have a certain seat to it inside there and you're gonna be moving that slightly and then it will leak afterwards so if you ever take these guns apart and you think you're just going to clean them and put them back together more than likely it's gonna leak afterwards so front part comes off right here we've got the needle exposed right here I'm gonna remove the rear of it than on the rear of the gun there's a spring right here on the back right here and one of the other things we typically have are is a bucket I used to always use just a can I've put all my parts into a can and one of the clean solutions you could use in years passes use lacquer thinner or reducer 54 which would clean them really good but you need gloves if you're gonna be handling getting those chemicals because it can absorb it here significant it's really hard on your liver so this thing comes out there's a spring this back comes off now the needles fully exposed we now just use simple green when cleaning our components and it's environmentally safe and you can get it on your hands it is good practice to use gloves we're not using it right now the next step I've got the front of the
