The valve assembly removed.
Detail of the piercing clamp screw. The square nut is captured by the grip frame.
The valve snaps out of the strap.
The mostly removed (by a previous owner) CO2 seal.
Hmmm… none of my other tools fit.
1/16” thick cold rolled steel…
Seal and valve body screw.
It’s probably a flat seal that deformed to fit.
Why not another pic? Odd that it came out looking orange, it’s redder in real life.
The valve stem. Seals against the red seal, when it’s knocked open gas flows from within the valve chamber, through the three radial holes and down through the valve stem.
A pretty stout return spring.
There were washers and a teflon (I’m assuming it’s teflon, could be anything) seal.
Other end showing the teflon seal.
The washers were a stack of 3.
I can’t figure out how to get that brass ring out. You can see a gap between the bottom and the ring where the seal goes. I think that the edges of the valve assembly were staked over it to retain it. Likewise I think the piercing pin was a press fit. So I’ll leave it. A new seal should snap into place if I make it the correct thickness and diameter.
What have I done? Good thing I took pictures. I'll work on getting it resealed soon.
