How to Disassemble the Valve:

In this article you will learn how to disassemble and reassemble your valve. 

The tools you will need:

Crescent wrench set

Pencil with eraser

Allen wrench (same size as the bolts for your gun)

Gun oil

Small flathead screwdriver

Sewing thread bobbin

STEP 1:

Remove the powertube from the gun and unscrew the asa/air hose from the valve.

Then unscrew the velocity adjuster. Do not unscrew it all the way, just enough to get the pencil eraser to hit the valve.

Push the valve with the pencil until it pops out the back of the powertube.

*Be careful, the valve and really fly out of the powertube*

STEP 2:

Place the valve with the pin in the Thread bobbin.

Use the eraser to push the brass plate past the asa/air hose hole. At
the same time, take the allen wrench and put it in the asa/air hose
hole.

This should stop the brass plate from coming back up.

STEP 3: (considered the hardest step)

Take the small flathead screwdriver and pry the end of the round clip holding the brass plate back.

This can be difficult but I assure you, that you can get it out. Try prying up and out of the groove.

Save the clip to be reinserted during reassembly.

STEP 4:

Press down on the plate with the pencil eraser and take out the allen wrench.

Take out the internals of the valve.

Replace any worn are cracked orings, and clean the spring.

Now is the time to replace any parts that are bad.

STEP 5: 

If you are replacing the valve housing, get it out now.

Visually inspect the inside of the valve to make sure there are no metal burrs.

Oil the valve internals and place them in the valve.

Press the brass plate down and place the allen wrench into the asa/airhose hole as before.

Insert the round clip, it should go in almost the exact same as it came
out. Don’t worry if its a little bent. This will actually help when
putting it back in.

Press down on the plate with the pencil eraser and take out the allen wrench. 

Replace the valve oring if necessary.

STEP 6:

Put the valve back in the powertube, using the pencil eraser to guide it into place.

STEP 7:

Your done, now enjoy the fruits of your labor.

	Nice post. I'd never try it, though. I'm afraid I'd never get everything back together right.

	Its pretty easy to put it all back together. There is only 4 parts in the internals. And all of them are pretty selfexplanitory on where they go. If you feel that your valve is leaking, need a new spring, or just want to get gunk out of it. Then I highly sugest you give it a try. But if you just want to casually take it apart to see whats inside, its definatly not built for that.
