Default cps 2500 nozzle repair

hey, its me again.

last weekend we were in austria on holiday and we had a spontanious, massive squirt-fest(well it wasnt that spontanious as some people had brought some blasters in anticipation of one).
anyway, two of my guns broke, one of them being my cps 2500 which is now leaking from the nozzle and doesnt build up pressure. i read the guides on how to repair it, so i took the blaster apart and got the screws off the purple thing that contains the nozzle valve.



i just cant get it apart, its glued so thight. i tried getting it open with a knife and with a screw driver, but that didnt work. im about to get a saw to open it for good

does someone know how to get it open, because the guy that wrote the howto on isoaker.com somehow managed to do that.

My 2500 did the same thing, and I'm now in the process of fixing it. I managed to get mine apart by taking a box knife and very carefully scrapping at the seam in one area. I then put the blade in the groove I made and applied pressure. Then the whole thing just kind of popped open.

Just be careful, it scared the crap out of me when the blade went through the seam. I was just trying to weaken it before I soaked it in hot water, which is another option you can try if you can't cut it open.

Now I just need a new rubber washer for the seal, the one inside was deformed.

how did you get your knife into the seam?
i cant get it in there at all and theres no way i can get the glue out of the seam. ive tried to saw my way in there with a small bread knife but even with that i cant get deeper than a tenth of inch....

Did you try the rubber band repair? You don't need to cut anything open for that, so that is a better place to start. If that doesn't work, try cutting in with a small thin saw, not something like a hacksaw, as that will take out lots of plastic, preventing it from going back together.

allright people, im getting desperate.
i cut the whole thing with my small saw to a depth of about a quarter of an inch (or a little more).



i still cant get it apart. i tried with a knife, i put in the seam and twisted it......well, i bent the knife......

should i cut deeper? could i damage the rubberring inside if i cut too deep?
is there any other way?

Are you sober? Did you unscrew the screws? Check again.

Other suggestions. Wait for someone who has actually seen a pull valve with their own eyes.

Default Re: cps 2500 nozzle repair

ive looked through some old threads and it seems that those people only had glue on their seam. my gun has it on the seam and in the seam. maybe thats the problem.
or did i forget something else?
i unscrewed the 9 screws that are around the edge of the nozzle valve, and then i just tried to open it. is there something i missed ( like a hidden screw or sth)?

any kind of help is highly appreciated!

Try spinning the two parts. If there is just one screw left, it will rotate.

If there is a screw inside, you would "feel" it while sawing. Sawing through plastic and then through a metal screw feels and sounds very distinctive.

What would help for sawing something as sensitive as a trigger valve would be a mini diamond wheel saw blade thing. I don't know the term for it, but it's essentially a very thin cutting wheel that you attach to something like a drill or other power tool base. It can do that job in a couple of minutes. You can damage things inside by sawing too deep, but you need to get through all of the outer plastic. Of course it won't budge if you haven't gone deep enough. You should be able to see the inside of the valve through the cut.
