This one's easy, it's the valve body. Inlet valve on the left (faces the piston in the pump), hammer hits the valve stem on the right, air comes out the hole in the top. This has a check valve on the input end, the valve fulls with more air on each pump.The Steroid upgrade includes a thrid o-ring on the other side of the air port. Otherwise when you fire the whole area between the rings has to be filled with stored air.What do I win?Doug Owen

It's part of the pump for that Sheridan. What do you need to do?

so does it come apart, if so, how? special tools? Does a groove for the 3rd O ring have to be machined? Does the valve stem move?What inspired this is that it was leaking during pumping. You could hear it hiss out the barrel...

I see that Pyramid air has a kit for $30. Which is probably what I'll do but I've never had one apart before and trying to figure out the operation for a better understanding. I see the piston has some scratches on the body, does this matter?

I've seen parts beak downs of these guns online but at the very moment I can't remember which site it was on. You know you can buy repair kits for them that have directions in with the parts.

I should dig around a bit more at the PK from Pyramid Air doesn't come w/ directions. They do have a low rez exploded diagram tho.

I bought repair parts for my old Crossman I wanted to restore just for kicks. When you call the tech support, ask them for an exploded view to work from. They sent me instructions for each part I ordered. It is somewhat like the Chinese puzzle boxes, some of the assembly has to be done in a specific order.db

I got the repair parts but on inspection I think Sheridan cheaped out on the valve body. No special tool to remove either. The inlet valve is a plastic plug followed by a single spring to the exhaust valve. I guess my question is where does the lead 'O' ring and the little brass button with a rubber center go?

Really? I wonder what's up with that? Sure enough, that's strange something would disappear that fast. I'll have a look around.
