Cup Seal issues
 
Okay, I am replacing the cupseal on my Core ZX. I purchased a Zeus parts kit, since they are the "same". For some reason the new cupseal/pin that came with the parts kit is not the same length as the old one

The new one does not seem to be screwed into the delrin seal all the way.
Does this small difference matter? I have tried to screw the pin into the delrin some more, but it will not go.
???
I put the new cupseal in, and I am still having a leak down the barrel. All the orings have been changed in the valve assembly, along with a new cupseal and it still leaks. I used to get close to 20 usable shots out of it, but I am only getting about 8.

You said you can't screw the new stem in, can you un screw it? If you can swap it with the stem from the old cupseal and try that. I must say I don't own and have never used one of these but I'm ok at troubleshooting problems. Give this a shot and let us know.

Good KLuck

No I cannot budge it. I have replaced the springs, kept the old cupseal, and lapped the cupseal face on the valve. It worked like a charm this past weekend, and finally got my first elimination with it on Saturday. Unfortunatly I lost the Co2 screw/plug on Sunday afternoon. So once again it is out of action till I order a new one.
