Update: After a couple of hours of searching I managed to find the missing piece. With the help of a bit of masking tape it is now back in the rifle where it should be!

It is important the spring it’s there for a reason. Use a big magnet to find it . Or use an old pillowcase to put over it when putting it back in place . I know how I would have put the little spring back in , but we all use different methods . It’s not complete without that . I once saw a mechanic putting a new clutch in a VWK70 I think it was . When he had finished the job ,he showed me a few bolts left over ……he said oh well and threw them in the bin . Those bolts were there for a reason. I thought do not bring your car here for a repair . Its pride with me ,just taking care and a little time makes all the difference.

Thanks to this video, I was able to take apart and repair a leaking O ring where the brass tube goes into the CO2 pressure chamber in the buttstock. After disassembling it and looking at the parts, I discovered the original O ring had hardened and wasn't sealing properly. A new O ring, put it all back together, and it works flawlessly. Thanks for the help, mate. couldn't have done it without you. for those wondering, I've had the rifle for a couple years with no leaks, and used it a lot in that time. in this case, the leak started after it got carelessly knocked over a couple times. This can cause the buttstock to slightly bend to the right or the left, which can unseat that brass tube and O ring where it goes into the pressure chamber. an old hard O ring won't conform back to the tube when that happens, and then you get a leak. It's an easy fix, if you have some really small O rings and this video to show you how to get it apart.

Thanks for the video Alan. Interresting. Keep safe and stay well.

Excellent....enjoyed this, always find it terrifying pulling things like this apart 😅

Having just purchased this rifle, this video will come in handy if/when mine starts to leak. Thanks for the great video.

Handy video buddy, thanks for taking the time to make a video. The question of why there's a mixture of slotted and philip screw heads is an easy one, the slotted ones are the ones you can obviously see when the guns together (in keeping with the real Winnie) and the hidden ones are all self tapping philips that you'll only see once you start to disassemble. You've done a grand job though buddy 🙂

Great video

My four year old “Cowboy” gun started leaking recently and leaking at the valve. Thanks much,when I do take it on this will help immensely.

Very good! Thanks!

Brilliant !!!

I wonder if Umerex have any plans to rifle and pcp this ? I think there are some pcp cowboy rifles, but they’re not as close as this. Thnx for the vid.

Thank you

Interesting exercise Alan. Years later you will find those MIA parts and instatntly know what they are. Don't ask me how I know. Cheers Rob

thanks

i hav been longing to have one even the spring type, , not always available in the Phils.

I'm having a problem with the CO2 cylinders not screwing in real easy. Is there anything I can do to fix it because it's leaking now.

Loved your video, thanks for sharing! Does anyone know if its possible to "adjust" the valve (maybe the spring inside it) to make the rifle shoot less hard? Thanks for the help in advance!

Hi Bud. Saw your original review of this. How long did you have it /shots, before the leak started? Really fancy one,..but !

Really interesting and useful video. Do you think that applying the silicone oil whilst still assembled,would’ve cured, or prevented the leak ? ….By the way,….I’ve found your spring…it was behind my settee.

Hey Alan, would it not be prudent to take the gas cylinder out on re-assembly? By the way where did you get your leather apron? cheers

What tool did you use to disasemble the part that was leaking? I'm trying to open mine and I absolutely can not get the valve open

👍👍👍👍👍👍👍👍 bfn Kev

When you said you had reassembled the valve slightly wrong, what was it? I've got exact problem all seals look good still got a slow leak. I put the green o ring in first with the slightly flat side up, then the washer flat side down then the valve with spring.

Has anyone tried using silicone O rings on CO2 guns?

it is acurrate this replica? i like very much and I want to buy this...what are you advise? at the 50m distance,penetrating the metal can of cola?

Are the iron sights on this removable at all? I love the blacked out renegade version but hate the oversize cocking handle. So I would either want to have this version and remove the iron sights. Or swap the cocking handles over and put the smaller one from this rifle on the renegade

I’m just gonna paint my stock and Handguard black for a renegade look. So this video helped me take them off, although I might just paint the Handguard while it’s on and tape block, seems a lot harder to take off then the stock

9:20 Did you use a special tool to unscrew the valve assembly?

Favorite rifle did you Play herry potter

nice video but mine leakage is at the co2- cartridge holder its a small little O ring whats leaking but i dont know how to repair this

I hope you respond 🙏 I have this rifle airsoft version But the lever safety pin doesn't meet the lever How could I fix that ? Pls let me know

Where can you find the parts for the legendary cowboy rifle and the 45 caliber peacemaker CO2

Hey I’ve got an issue with the hammer, it can lock in place but it is loose and doesn’t strike when the trigger is pulled. Any help would be great

The CO2 chamber seems to be cross threaded. It's a hard to screw in that I messed up my Allen screw that's on the end of a gun.

After I got the stock off. The piercer was screwed in just fine. I was able to unscrew it and screw it in without no problems. That was without a cylinder in it. I was told by the umarex company that you were only supposed to use umarex CO2 cylinders . The Umarex co2 cylinders was longer than the rest so could that be the problem? I uses co2 crossman cylinders.

How did you disassemble the valve system?

Mine has for some reason developed a barrel wobble similar to the single action army replica
