The Airbrush and Complete Overhaul

In this video, we're going to take apart the airbrush and talk about some of it's components as well as showing you how I do a complete overhaul with the airbrush if needed.  Most of the time and I highly enforce this, you don't need to take the airbrush completely apart, but sometimes if there's a problem or maybe just one in those blue moon complete maintainence, you need to so I show you how.
So here's the video but I'll go ahead and write down the instructions here for better reference later.  

Here's a reference chart to the Krome. As the Krome is a gravity feed airbrush most of them are pretty much made the same except for a few differences across brands.

Here are the step by step instructions for the overhaul clean up routine I use:

  1. Unscrew the rear brass handle. (make sure you don't lose any O-Rings there)
  2. Unscrew the needle chuck.
  3. Carefully, slide out the needle.
  4. Remove the trigger and put it aside.
  5. Unscrew the tube shank.
  6. (optional) Unscrew the spring screw and carefully let the spring fall out.
  7. The needle tube should have fallen out when you unscrewed the tube shank. Put aside.
  8. The back leveler should have fallen out when you unscrewed the tube shank. Put aside.
  9. Unscrew the spray regulator.
  10. Unscrew the hold down ring and BE CAREFUL of the needle tip.
  11. The needle tip can be removed and set aside. Be careful of it as it's small and you can warp it if you manhandle it too much.  Some airbrushes need a wrench to unscrew the needle tip.
  12. Wipe down the spray regulator, needle tip and needle.  This is where an Ultrasonic Cleaner comes in handy.
  13. Set the needle tip back into the seat of the shell.  If you don't need lube here if your needle doesn't need to be wrenched in.  If it does, apply some lube to the threads and screw it back in.
  14. Apply some lube to the threads on the hold down ring and screw back in.
  15. Apply some lube to the threads on the spray regulator and screw back in.
  16. If you took the tube shank apart, then lube the spring and the threads on the spring screw and screw that back in.
  17. Lube the needle tube and slide it into the tube shank and make sure it matches the shape of the hole.  It should slide all the way in. Now screw the needle tube into the shell a few twists.
  18. Slide the back lever into the shell, the bow should be facing to the rear of the airbrush.
  19. Now continue to screw the needle tube completely into the shell paying attention to the needle tube making sure it can still slide all they way into the tube shank.
  20. If you slid the back level into the airbrush correctly, the needle tube should be pushing against it and when pulling back should be smooth.
  21. Slide back the back lever and slide in the trigger.  The hole in the trigger should be align front to back of the airbrush. The trigger should be sitting on top of the trigger mechanism and should have no problems being pushed down smoothly.
  22. Coat the needle with lube and carefully, slide in the needle.  Make sure the trigger is set right and fully in the airbrush or you might push your needle into it and ding the tip.
  23. Apply lube to the threads on the back of the needle tube and screw back on the needle chuck.
  24. Apply lube to the threads on the brass handle a screw it back on to the shell.
  25. Wipe down the airbrush for any access lube.

When screwing back in parts on an airbrush like the Krome, you only need to finger tighten it back. Do not force it too tight! There's no need to do that.

That's it guys! Hope this helped! :)
