I watched the video and decided since I had the cylinder already off to just go and rebuild it cleaned the check valve good and got all new o rings in it and Teflon tape I'm glad mine has the permanent ferrule on the air lines with the washer and o ring so you don't have to worry about the ferrule getting wore out and leaking.Never had that issue, because I always followed the directions on how to do it. It's all up on YouTube (as is pretty much anything you'd evver want to fix if you search for it). Since parts are no longer available for these wonderful little gems, it is important to do things right and not guess so you don't mess them up . . . .
These videos are of an older style, but they all work the same way - expect the black nut looks different since it does not have the auto lube system (that came later).
Cylinder removal:Cylinder rebuilds:
I’d imagine they fatigue after 3 1/2 years of holding back 300 bar.I was filling my small omega tank today and at almost 4500 psi I heard a loud pop ( scared the s--t out of me) and a wierd noise. Air was pumping out of one cylinder but the other cylinder was still woking. Closed the tank and turned off the compressor. Figured that it must be the burst disc and it was. Repalced it and cleaned the valves, tested it with a deadhead, filled my Huben to 300 bar, Everything worked ok.
I've had the compressor 3 1/2 years, 65 hours of use, first maintenance other than turning the grease ports.
Previously owned an Omega Supercharger - 5 1/2 years, 260 hours.
Hi I just came across the thread now. If I'm right the "#4 screw" is a probe alignment screw. At least that's what it seemed to do on mine. Just turn it in till the probe goes into the center of the breech. This could also potentially help the probe orings last longerAppreciate it. I did tighten screw 4 down a slight bit so it wasn't holding the rail up... which has solved my issue. Still would be nice to know what that one does, but hasn't effected anything that I can see.
Scope is 1". Vortex Diamondback. I could go with different rings, but was JUST out of reach. Tightening the rails and #4 did the trick and now everything is dialed.
May have to upgrade the rails for him eventually but we're both happy with the way its working now.
That's what I ended up doing after I read jimbentley's comment:Yep. ^
They threw me as well. A set of wirecutters works well to gently pry those off. Do one side first, then push on the pin that goes all the way through.
Cheers,

Thank you both for the helpThat is cap over the roll pin. It should just pop off.
That's a long shot ! What ammo are you shooting ?
This is not made by anyone in the US. Definitely not Don or Crosman.Looks like a custom crosman 2260 or something. Trigger looks different than a 2260/disco or even a QB78. Probably custom as well.
So it's probably a don cothran tube or similar. Is this HPA or bulk fill? Looks like bulk co2.
