Stuck needle with Passche airbursh help.

Posted by Carves on Tuesday, April 11, 2006 11:21 AM

Guys/Gals,
I have a Passche VL which I have not use for a long time. It is a gift from my friend who quit the hobby long time ago.

Few moment ago, I decide to take it a part and try to clean it.
It appears that the airbrush when given to me was not cleaned at all, so there are lots of paint still in the airbursh. To make it worse, the needle is stuck, I cannot pull it out from the housing. Tried it with pliyers with no luck. I need to pull it out because the needle is in bad shape and need replacement.

Any idea how to pull the stuck needle off ? Take the whole thing into lacher bath for a night ? Ideas... ideas .... help help ...!!

Ben,

You can soak it in lacquer but you have to remove the air valve assembly first as the lacquer will damage the O ring in there.
Also, try this for removing the needle, instead of trying to pull it straight out with pliers, grab the needle with the pliers and twist it back and forth to break the hold the paint has on the needle.
If it won't budge then remove the air valve assembly and soak it overnight.
Hope this helps.

I think that should be laquer thinner, not just laquer Smile [:)]

Remove the head assambly, be carefull don't lose the tip, it's inside the head. If there is paint build up around the needle at the tip end then clean it up with lacquer thinner. If you still can't remove the needle try to heat the back of the needle with a candle, it doesn't take much heat just repeat till the needle comes out. I discoverd this trick after almost ruining my air brush.

I'd have to go check but right off the top of my head I don't think you can get the air valve out of a VL with the needle installed. Doesn't it go in from the top? *makes note to check*

Yes, that's right. I think removing the tip and putting a few drops of lacquer thinner or MEK in there will have the best chance o freeing the needle.

Nope, it goes in from the bottom as most airbrushes do.

Right you are, my man. Wink [;)]

I never did check. Can't seem to pull the thing out of the drawer since I got my new brush. Big Smile [:D] Thanks for the exploded view!

If the tips we gave don't work then I suggest you use the advice from "Blaster" in the movie, "Uncommon Valor" when he said, "There is no problem that can't be solved with an appropriate charge of C4." Laugh [(-D]

Try solid/heavy body paint remover, after you remove the rings or they will melt. OR It's bent like a mo fo.

Depends on what you mean by "stuck".

This may sound stupid, but does the trigger move when you try to pull it back? If it does, it means that the needle might not actually be stuck in the head/tip. Have you loosened the needle lock nut/collar at the rear of the needle support/sleeve? If not, you may find that it is simply locked into the retention mechanism.

The lock nut is part 34 in the following diagram: http://acm.missouristate.edu/~jacktaylor/customs/ab/paasche-vl-ab-docs2.gif
