Ball Breaker

I ordered the level 10, should I also get the $20 complete o ring kit and change everything?

What actually is the level 10 replacing. Also, about the X-valve, what's the difference between it and an old valve w/ level 10 (besides the weight)?

Yeah if the ornings in your gun don't look anywhere near the ones inthe parts kit you can change them, especially if they are orriginal from over 10 years ago. On the other hand if the gun is working fine, well "If it ain't broke don't fix it" if something does go down it shouldn't take that long to fix anyway.

ok, I got the lvl 10 kit and I'm trying to get it going. The quick set up says to start w/ the #4 carrier & the medium spring. The instructions say the 4 carrier has two groves but the pics that came w/ the kit show the #4 carrier has two groves on each side, four total. Which is it?

Also, it says to use the medium spring and says that it'll be easy to tell 'cause one end is cut but this isn't really abvious by looking at them. There are three springs. One is short and gold and I think it's the lvl 7. Then there's a red one and a silver one that are almost the same hight (the silver is milimeters taller) and niether have an obvious cut end.

When I got the kit, I read the instructions and got to it. I realize now that I probably started w/ the #2 carrier & lvl7 spring and I'm out of air because a ton was leaking down the barrel like the instructions indicate.

Any tips for what to do when I get more air and how much of it should I have on hand to get this working properly?

toss a carrier in, and see if the bolt falls off when you turn it upside down, keep doing this going a size smaller each time until it doesnt do this.

sounds simple enough, what about the 'medium' spring that I'm supposed to use first. Does medium refer to lenght or strength? There's one that's pretty obvious to be a level 7, the other two are red and silver . . .

Hopefully I can have this working by Sunday so I don't have to rent one again . . .

The medium spring is the red one.

The rings go completely around the carrier for sizing.

The best method for sizing your carrier is to test fit it onto the bolt stem before you put it into the valve. You should be able to hold the bolt from falling when held vertically, but the slightest tap will cause it to fall. Try that to start. Do not install any shims. Test fire the gun. You will probably have to increase the velocity from its previous setting. If there are no leaks and the gun cycles properly, you are good to go. If there are leaks, go to the next smaller carrier using the same carrier oring. If the bolt sticks, go to the next larger carrier with the same carrier oring.

The carriers start at no lines or dots. Each dot represents 0.5. Each line represents 1, The line goes completely around the perimeter of the carrier. Eg; 1 line and 1 dot = 1.5. Most mags usually start with the 1.5 carrier.

I'm gettin' there . . . the level 10 is in w/ the red spring & no leaking down the barel. It is, however leaking out the back which it hadn't been doing when I test fired it with the original bolt assembly.

On the bright side, I shot about a hundred rounds at a pretty decent velocity (I don't have a chrono) and they were grouping pretty tight at about 60 feet - and none broke!


Any ideas why it started leaking out the back?

What are the shims for (there are currently none in)?

one more quick queston . . .

When I was trying out the different carriers was I adusting them to the new bold or the powe tube? I'd like to know if I can switch it to another valve w/out all of the adjusting

I haven't done a lvl 10 myself but you want to start with the silver spring.

Well theoretically every x valve is the same but in practice they aren't. You would need to fine tune it again most likely.

As for leaking out the back that shouldn't be caused at all by the level 10 since it is in the front of the gun. Degas it and debug the leak from the back part of the valve.

[Coralis]

The leak out the back is caused by the regulator piston ... the level 10 requires higher pressure than the level 7 the newer regulator pistons relieve at a higher pressure and thus will not leak when using the level 10 bolt.

so the part I should order is a new regulator piston? Please tell me it's less of a pain than the level 10 . . .

found the part, where does it go when I order a new one?

the regulator piston is pretty easy to install first unscrew the valve in halves and remove the urethane regulator seat you will want to replace this part most likely unless its already brand new ,then unscrew the velocity adjuster knob , then remove the spring pack (make a note of which way it came out so you install it the correct way ) then take a small allen wrench and push the regulator piston out . To install oil the oring on the reg piston and push it in (a large allen wrench works here then clean up your spring pack and coat with a thin coat of grease ( the grease is for corrosion resistance only so if you dont have the grease oil will do in a pinch) then install the spring pack then screw in the velocity adjuster knob (make sure you screw it in enough or the gun wont shoot or it its way low it wont even "cock" when air is turned on) then put a new regulator seat in and screw the valve halves back together and reinstall your valve .

The carrier and oring are set to fit the bolt stem. If you move the carrier and oring to a new valve, the same bolt will fit as well without further tuning.

fine tuning

once I get the new reg piston and all the kinks worked out since the valve is so old, how do I 'fine tune' the level 10?

should I bother trying the silver spring and a certain amount of springs or just leave it alone?
