Major Problem with Automag

[TheLaxPlayer]

I recently purchased an Automag off e-Bay and it has just arrived. There is a problem though. When I gas up the mag, air releases out the back of the valve through the regulator nut (velocity adjustor). I opened up the valve to see if I could find the problem, and think it is one of two things.

1. The Regulator Seal has turned yellow, and I don't know if it is sealing properly, but it is completely clean as the manual says it must be to function properly.

2. The Regulator Spring Pack seems to have been relpaced by a small rod with 25 shims on it. Is this normal, or is there supposed to be a spring there as it shows in the manual?

The velocity is not turned up too high, as it does this reguardless of the position of the regulator nut.

I have not taken apart the inside of the valve, or taken out the regulator piston, but those shouldn't cause the problem, should they?

Thanks for help, and I really need to get this gun working, hopefully without spending much money if any, as I spent it all buying the gun in the first place.

Check the speed. Air venting out the back often means it's shooting hot.

Hey Lax,

Shooting hot could be the problem but also if you dont look to see if your
reg piston o-ring is good you wont know. the reg piston o-ring is one of the last things to go wrong but you did buy it from someone else. Who knows what they tried to do to the gun. Give it a look an post reply...

I have no way of checking the velocity, but it is turned down ALL THE WAY.

The reg picton o-ring is old and hard, but not broken. I will replace the o-ring and the reg seal.

What about the spring being replaced with the rod with shims on it? Should I buy a spring and put it in?

Hey Lax,

if you are talking about the spring pack it is a buch of shim looking rings attached to a rod with one larger one on the other end.( the screw) Here's a pic from the agd web site http://store.airgun.com/index.cfm?fu...&categoryID=18
you may have to copy an past the link i'm not sure. the reg piston o-ring shouldn't be hard. that may be your problem. if its hard its not creating the seal you need to hold the air pressure from leaking. lmk if the pic is the same as your sping pack....

Yes, that's the part. I suppose that is what it should have, I was thrown off by the name and the picture in the maunal. I suppose I will have to order the piston 0-ring and regulator seal/seat though, as my local store doesn't have any.

Do you know about what price shipping would be for two of each to Michigan?

Hey Lax,


Dont just buy the 2 o-rings.It will be more expencive that way with shipping an all. Get the mag repair kit. It has every thing you need plus a few extras. Your local store should have them for about 20 bux. When you change the o-rings change the bolt spring also as this will help out either way. Make sure you oil everything good before replacing parts. Dry an new o-rings will catch on the smallest thing an cut or break,also clean everthing well too. Dont want any dirt or forien objects getting into the gun. Keep me posted on any other probs if any after changing these parts i'll try to help in any way....

$14, one reg seat and one piston o-ring later, it works perfectly.

I got the parts kit at the local store, but it is not the AGD kit. It is labeled as an Automag "First-Aid Kit" and is just o-rings and reg seats. I put in the piston o-ring and the reg seat, and it works very well now. I cleaned and oiled everything while it was taken apart.

Thanks for the help!

Bye the way, any idea how old an Automag is with the serial number "CF17xxx" ?

No stars on the valve, but it seems easy enough to repair on my own. I do however recommend for the people reading this to get the AGD kit over these first-aid kits, as some of the o-rings in this kit do not fit properly, allowing leaks. The parts I needed are fine though.

My Mag is low 10xxx ( low 10k, I don't want to give whole #) and I'm 2nd owner and think guy I bought off of purchased it around 1992-93. I need to ask friend who bought his about same time if he remembers.

Hey Lax,


Glad everything is going well now. 2 things 1 you probally shoundnt post your serial # in here to many ways an thing weirdos can do with it. edit the # out to be safe. Spectre if you see this edit your to please. Second my serial # is over 10000 lower than yours. i got my mag back inlike 93. When i registered it with AGD the tech told me my gun was pretty old. Now of course i dont use it no more i have an X-valve, but i'm building a spare gun with tmy old valve. for my friends to use when they go with me. I like my mag an will never onw another type of gun. Glad to help with you problem an make sure you buy a mag....lol
