As the Title says, I have a leaky Disco! LOL Every time I fill, it empties to about 1100-1200 PSI, and stays steady after that.I have been oiling the O-Ring on the bolt, if that helps. Where are the other seals, so I can check if they are busted? Also, how can I tell which one needs replacing?

Thanks

Jr.

Mine does the same thing. Had it about 9 months and around 1500 shots thru it.

The last 2 times I shot it I pumped it up full and shot down to 1000 psi and put it up.
I read it's better to leave a PCP with pressure to keep dirt out of the seals.
I also read of someone saying a small bit of anything in the seal will cause a
leak. I don't feel like taking it down just yet to clean it out as I don't have a shop
to properly disassemble and put it back together safely.

So I'll just have to pump a few more strokes when I want to shoot.
Would be nice to know it's at pressure if you need it quick tho.
I keep the Titan by the door for that.

mine drains down to nothing after a day or 2. need to open it up and replace all the orings eventually. maybe after deer season is over.

Take a small glass and a drop or two of dish top with a little bit of water, then apply this solution to your gun using a straw at the fill adapter, and around the gauge (stock removed). If there is a leak the solution of water and soap will foam like a mad man and boom you have found the leak. Once that is done we can go from there on how to fix it...

maybe the gauge worked loose a little
seems like most of the time it boils down to the gauge.
gecoguy has a good idea and its a place to start

JrSquirreler · « **Reply #5 on:** October 15, 2012, 08:12:40 PM »

alright. I will do the Soap test and get back with you! Do I put water on the Seal of the fill adapter, or whole thing?

Well I pumped up to 2000 PSI, and the gun does not seem to be leaking anymore. Im not sure if the air loss was due to weather changes, but I'm glad its all cleared up.

I have talked to crosman before regarding this issue. And basically what they told me is to make sure when you are finished pumping the gun to bleed the line quickly. Other wise if you open that bleed valve slowly on the pump the fill valve will stick open a little causing a leak.

Why so faint of heart, Cordero? It appears to have been a temporary glitch is all and Geco pointed out a viable solution which is in the pump operation manuals. Please don't let that turn you away from a good gun; you deserve the opportunity to own a disco brother besides which, a disco is easy enough to tear down and rebuild if necessary.

Well it just seems like a lot of guys have had this problem. Not to mention, the initial investment into PCP is high. And if you want to be serious, then a $170+ tank is necessary. Then you gotta get all the adapters and such. All of which i know nothing about.

Well a lot of us don't have this problem and a $170+ tank is not necessary.✌

sounds like there was a piece of debris in the fill nipple preventing the check valve from closing all the way or from seating correctly
well glad it sorted itself out
if you are not covering your quick detatch on the pump/tant you are using its a good idea to cover it.they sell a cool little plug for the quick detach on ebay for a couple of $$ it will save you a headache

Oh how I love ebay...

Scratch that.... $:-\$ After checking the fill pressure after getting home from School, it had dropped to about 1200-1300 PSI. I have tried the soap test, but nothing. I will try again now.

if you have a few tools and mechanically inclined degas pop the fill adapter off lsy the parts out in an order you can remember clean it up then reassemble
now that i think about it though, my gauge leaked the pressure dropped down to a certain amount i can not remember
i changed the o-ring as a precaution wrapped 2-3 layers of plumbers tape around the threads reinstalled.it held air for a long time
i left out in the garage at -30 outside probably -20 in the garage after 3 weeks,maybe longer, the pressure was the same as when first put there

Did you remove the stock to do the soap test on the gauge?

Yup, and I did not see any bubbling!

GecoGuy · « **Reply #18 on:** October 18, 2012, 08:54:26 PM »

Hmmmm...next thing I would do is put a balloon on the end of the rifle over a 24hr period, and make sure it is sealed tight. Close the bolt and if the balloon fills up then it is something internally, I forget how to fix it because I haven't had to do it..................yet.

Let us know what you get when you do this.

MustangMike · « **Reply #19 on:** October 20, 2012, 08:13:19 PM »

size 016 orings

tear the disco down its super easy to do, there are 6 internal orings in the tube. 2 on the fill adapter, 2 on the gauge block and 2 on the valve, then a smaller oring in the gauge block between it and the adapter for the gauge...
