do YOU know what 2 do?

Dimitris

Mac-Valve Maestro!
so i've disided today to clean my airbrush cause there was paint residue in the air chamber. So I cleaned it. :)
When i try to turn the guide screw back in i understood right away that it would't and
while slowly removing the tweerers, the guide screw with the spring dissappeared...
I found the guide screw but lost the spring and will order one, but what's going on with the guide screw? I looked inside with a magnifier an looks ok.

Any suggestions what to do?
Thanks a lot!

Looking at the first picture it appears that the threads are striped and is it cracked? Hard to really tell by the picture . But it the threads are striped you can use a thread file to dress them up and put them back like they should be . Looking at the location where it goes the threads look good.
Or when you order the spring goes ahead and order the new guide screw too.
 
when you start the guide screw push it against the threads and turn it counter clockwise till you feel it drop into the thread then turn it clockwise till it seats

Thanks Mr. Micron!, efinetely will do!
 
If the screw will not go in, sometimes turning it over will solve the problem... I've had this happen many times;).
 
Good morning from Greece, so I got a call from the store where I send the revolution for service and told me that it's the threads of the airbrush that's been damaged. The new guide screw was the problem, he replaced it, but when he reached at the end where the o-ring seals up, it leaves a tiny gap where the air escapes when you turn it on. Anybody got any suggestions what to do? It's a pity to lose one gun cause of that...
 
I'm having a hard time trying to figure out where the "air" would be leaking from. Even if the guide screw isn't in all the way. The guide screw puts tension on the spring and holds the trigger piston in place allowing you to push the trigger up and down. The piston allows air from the hose into the airbrush. Does the trigger have any tension? Is the air leaking from the guide screw or is there is air coming out the trigger area it could be the trigger o-ring needs replacing.

Before you took the trigger apart was the trigger "slow" to return?

Sorry I can't edit my post - he was able to get the screw guide on? but when he turns on the compressor air is escaping out of the trigger?
 
Where is the air escaping from? The guide screw?

No, the guide screw is replaced and works ok. But when it reaches the end of the way and tightens, you open the air flow and without pressing the trigger, there's a continuous leak of air. He told me that's probably a problem caused by the threads in the airbrush body (damaged) and he won't tighten the guide screw to see if it stops the air leak. Told him to send it to me and I'll try to do so.
 
Hi Dimitris when you say "continuous leak of air" is that out the end of the airbrush? or out the trigger area?
 
I got back my AB today and don't know what's going on with it. Seems like it's preparing its own funeral or something...:cool::cool:

watch the video and you'll know what I'm talking about. Any suggestions are welcome, you'd have helped save the life and soul of an aged matured AB!:p

Ok filoi (friends), the problem was the o-ring in the air chamber. But I need your help, can someone inform me what size the o-ring is so I can buy a bunch of them for back up?
thanks in advance.
