Rough spot inside my On/Off

[Frank (the spank)]

As I was cleaning my E-Mag for the first time (brand new) I noticed that inside the on/off there is what looks like a burr in trhe metal. The flat spot where the two O-Rings that sit inside of one another. Maybe not a burr.. like a gouge was taken out.

And... I have a leak. when I hold the trigger I get a small leak that fizzles away after a few seconds. I replaced the O-Ring and get the same thing.

Man.... am I gonna have to send off my E-Mag to AGD already?

The on/off pin should be round thoughout its length.

Frank,

Are you refering to the flat surface on the on/off top, that contacts the quad O-ring (which is inside another O-ring).

Also, when you say,

when I hold the trigger I get a small leak that fizzles away after a few seconds

are you saying when you hold the trigger ALL the way back?

A gouge on that area could potentially cause on/off leaking issues...a lot depends on the size, depth, and exact position of the gouge. Can you carefully rub that area on some fine (400 or 600 grit) emery paper? That could help flatten out the surface.

Also, this might all be for naught, if the gun doesn't leak when NOT holding the trigger in, who cares? There really is no need to ever do that.

Could you take a pic or a scan?

[Frank (the spank)]

Yes, it is the flat surface area on the on/off top that is part of the valve body...

Basicly looks like a mistake when they cut the valve. Too small to get sand paper in there.

I care because.. well.. the gun is brand new

If I send it back will I get a new one with the same serial#'s? If I do send it in... I'm screwed for next weekend of playing.

[Russ]

Oh, the area INSIDE the valve body...I thought you meant the (brass) on/off top...never mind.

But if it doesn't leak when you're not holding the trigger back, who cares? If it leaks when the trigger is released, and you have exhausted all other LX possibilities, then you should send the whole gun to AGD for a fix/tune-up.

Yes, it sucks, but that would be what I'd do.

[Frank (the spank)]

::sigh::

Any idea on the turn around?

Thanks for the advice, just sucks I gotta send in my new gun for this and miss a game....

There is a little flat spot on the on/off top. It is supposed to be there. Don't worry about it.

The leak you are experiencing is a power tube leak.

If you are using a level 10 bolt, then remove one shim.

[Frank (the spank)]

Not a flat spot, the inside of the on/off, ya know.. where the two O-rings sit inside eachother. That has a rough spot, like a mistake in the milling.

how can it be the power tube when the trigger is held? No air is in the chamber for the power tube o-ring to seal, when I let go of the trigger I hear no leaks, when I fire and hold the trigger there is a small leak that fizzles and seals in about 30 seconds. new gun and new seals, but i replaced all the on/off o-rings to be sure and the same thing happens.

i wouldn't care that much but the gun is brand new, so I think I'm gonna have to send it in...

Do I just fill out the form on the page for repairs and send it in? Anyone know how long it should take? can I just send in my valve or should I send in the whole gun?

[Russ]

Frank,

You may be obsessing

Does the gun shoot OK? Does it have any little fizzy leaks when you DON'T hold the trigger back? Are you going to answer that Q?

[Frank (the spank)]

Yeah... I am, lol

It doesn't leak any other time, just when I hold the trigger in manual mode. It was a jagged piece of metal, i tried to scrape it with a dental pick because I thought it was crud but it didn't go away and thats when I saw that it was metal.

I'm obsessing because when I spend as much as I did on this gun I treat it like I'm gonna have it forever, and if you treat your mag right... it will actually last forever.

lemme see if I can get a picture of it..

[Frank (the spank)]

my camera is retarded and can't focus on anything.. but here is what I got. That area is smoother since i scrapped it with a dental pick.. but still un-even and leaking.

The level 10 bolt hold a high residual pressure in the valve chamber even after it fires. That's why you can still get leaking if you hold the trigger. The leaking usually continues until some of the excess air bleeds out of the valve allowing the bolt to reseat itself farther back into the power tube thus covering the vent hole with the carrier o-ring.

When you release the trigger and the front chamber fills with air, the pressure of the air helps provide a tight seal for the o-rings. This is almost always fixed by removing a shim or going to a smaller carrier.

[Frank (the spank)]

ah, thanks! I'll give that a try

First of all, that leak is a side-effect of having a good LX o-ring fit. As long as it doesn't leak down the barrel when it's just sitting and as long as it doesn't sputter on the first shot after the gun has sat for awhile, leave the LX setting alone.

Is this an aluminum valve? If it is, that might just be a spot that didn't get anodized. My XRTP valve is like that. If it's an actual physical burr sticking out, then I would get it taken care of. If it's a small gouge, I wouldn't worry about that, because when the gun is gassed up the o-rings don't sit on that surface anymore. They are pressed against the top of the on/off assembly.

[Frank (the spank)]

I scrapped the on/off with a dental pick some more and it looks like it was crud which then left an un-ano'ed spot.

I guess I am used to the old mags.. not this new fangled lvl X stuff, lol. I went to a tighter carrier annd all leaks stopped. After playing Saturday my gun would sometimes leak with the trigger not held, a few shots it would stop, a few more and it would leak. Now.. seems to be working fine.

Thanks athomas and BlackVCG and everyone else. AO once again helped me out.
