Problem with XVavle

[Enhander]

I just recently started having an issue with my XVavle and was hoping some of you all could help me.

I aired up my Tac-One a few days ago to make sure everything was good to go for my game this Saturday. Aired it up and there was no leaks. Took it outside, fired on shot and it started leaking and the bolt would not reset.

Now mind you, Ive had this XValve came to me with my Tac-One that I bought directly from AGD. This is the first problem Ive had with it in 4 years.

I checked the O-rings, oiled it and all that fun stuff. Nothing worked. Im running the stock RT On/Off with 2 shims in my lvl 10. I tried adjusting the carriers, starting with the lowest one (no dots or stripes on the carrier) That carrier stopped the leak..but every trigger pull made the marker full auto. So went up on carrier and the leak started because the bolt would not reset.

Also please keep in mind when I was adjusting the carriers, I was using a ULT. I removed the ULT and put my stock On/Off in it and its still having an issue.

I havent gone as far as replacing all the o-rings yet, but does anyone have any idea of what its doing?

Thanks in advance!

Are you saying that it is going full auto every pull? Did you put the large oring down in the on/off hole before inserting the on/off assy w/small oring on the pin?

It was going F/A with the ULT. But I removed it and put the stock On/Off. Now that you mention it....When I put the stock RT back in last night I didnt see the large O-ring down there.

If thats the problem Im going kick myself...

Of course, check the on/off first. But also, if I recall correctly, when tuning the Level 10 you should start with the largest carrier that doesn't cause a leak. I've had better luck with no shims in the Level 10, too. A carrier that is too small might be contributing to the bolt stick.

I've had that problem before. Use the same carrier O ring each time and move it from carrier to carrier. Usually you can get an idea if you have a good combo by sliding the carrier with o ring onto the stem of the bolt and checking the friction. Too much friction will stick, too little will leak.

Im confused. According to this:

Theres no o-ring before the small on/off o-ring..or am I reading this diagram wrong?

[Tunaman]

That diagram is of a Retro Valve...the Xvalve has another oring there not shown in that diagram.

[Enhander]

Gotcha. Now its driving me nuts...I want to get home from work to try and fix it.

Btw Tuna, check your email

[Enhander]

Anyone have a pic of that O-ring? Just so I know what Im looking for?

[Enhander]

Cancel that... I reference my ULT install guide I posted on Spec Ops....all the pics I needed lol

[Enhander]

Ok. I was missing the O-ring. I replaced the o-ring and put the old carrier I had installed and the leaked stopped. However the bolt does not reset when I fire. Ideas?

[Enhander]

Any ideas gents?

[Justus]

By the "old" carrier, do you mean the largest carrier you have? Also, have you chrono'd the marker to check whether or not your velocity is turned up where it should be? And... you didn't change the bolt spring did you? Those things are what I started with when I was facing a bolt stick issue a couple months ago.

The the largest one the carrier with no dots or stripes? I think its .05? Im using the carrier with 1 dot.

Bolt spring has stayed the same, gold. Ill try adjusting the velocity, but I never messed with it since the last I used it. Which was in November last year.

[Justus]

I thought it was the other way around. No dots = smallest. Then the dots = half step up, stripes = full step larger. I could be backwards? I'll check.....

Edit: Yeah I had it right:
