68 Carbine

Hey what's up guys,

I have an old 68 carbine, and the bolt leaks gas. I don't really see any way to repair this, because unless I really screw with it, which I'm hesitant to do, you really can't break it down any further.

Does Tippmann offer replacement bolts, or am I going to have to continue scouring ebay?

And if they still do offer replacement bolts, how much would one run for?

Thanks.

Oh, and I DO NOT want to get a new gun, because my current set up works very, very well when it is in working shape.

OK, I was mistaken, the "bolt" is just the hunk of metal that acts as a hammer, and it holds no pressure, so thats not what is leaking. Rather the "CA-V Valve" leaks.

 Originally I thought the seal on the bottom is what leaked, but that turned out to be false. Or maybe its a combination of both, but I think it's just the chamber thing that leaks. See the expansion chamber? Trace the plumbing back to where it enters the bottom of the weapon and feeds up into the bolt/chamber portion inside the weapon. The tragic thing is that while it does screw into the bottom of the gun, it does not actually screw into the valve/bolt/chamber itself. Normally it just kind of sits in place with the aid of some plumbers putty I suppose. Again, there is no actual threading for it to screw into.

HOWEVER! On closer examination, I was just checking the chamber/valve for the hell of it by blowing in the bottom hole. Normally, it should hold the air pressure, and when I hit the "firering pin" (?), which is what releases the gas pressure when the hammber/rear bolt slams forward into it. That is what leaks. I don't want to crack the bolt open, but in the front of it where it's flat there is this plug thats been tapped in there once the construction of it was done. Im sure I could open that up, but I'm afraid I'd ruin the bolt/valve/chamber. It seems like it's not getting a good seal internally, and hence it leaks.

Don't bump the bump on no big fat woman

Gerbil of Doom;

Thanks, it appears to be working. When I have more time, I'll set it down with a full tank in and let it sit for a while. If it hasn't lost all pressure by the end of the day, I know it's good to go. But at least now it works.

Thanks!
