Help with Daisy/WInchester Model 600X Disassembly

Wasn't sure where to put this since there's no South American Air Gun Gate. This one was made in Brazil, not Turkey, Any help would be much appreciated.
Brazilian-made Winchester Model 600X. I bought this for my youngest daughter when she was 6, so 17 years ago. Guessing it had been in the store for a few years, probably at least 20 years old. Been sitting for about 15. Have been told the seals in these were leather, supported by the fact the manual says to lube the seals with motor oil. It will cock and fire put doesn't push the pellet out so I assume the seals are the issue. What I can see of the spring looks good, no rust, not broken. Teh seals in the Brazilian guns were apparently a different size than the Turkish (Hatsan I think?) made ones and I can't find them. Brian at Veradium Air said he'd do custom seals if needed so I thought I'd take it apart. Disassembly was pretty straightforward until now. Housing for the trigger assembly is welded to the compression tube. Easy enough, remove one pin and the trigger and spring come out. Safety mechanism is a bar, remove the spring for that and it slides freely. Attached to the housing by the pin I haven't punched out yet, which also appears to hold the sear in place. It's all connected to the plastic cap with safety switch you see on the end and that's where the fun starts. I can't get that dang cap to budge. If you look at the last pic from underside of the barrel you can see the seam where the plastic cap hits the cap for the spring. You can't push on this plastic cap to compress the spring because it's right up against the compression tube and it's not going to move. So, it has to come out for me to get the spring compressed so I can remove the pin you see in the side views. Put rag around it and tried to pull with pliers, didn't budge. There's no lip or anything for me to tap it out other than hitting on the linkage for the safety mechanism and I'm loathe to do that. I there a trick I'm missing? I might have to tap that other pin out and remove the safety bar and sear from the housing. in the end but there's enough play there now that I should be able to get the plastic cap to at least move and test that theory, but it won't. You can see the sear in the R side view. I hope I don't have to remove that pin because getting the sear and spring back in that housing is probably going to make me use bad words. But I can't find out until I get this plastic end cap to budge!
Edit: Oh, and the small indentation forward of the plastic end cap is where the trigger spring rides. Looks like it's actually molded into the cap for the spring, the pin goes through the compression tube assembly between the plastic end cap and that indentation. And then forward of that is the spring guide.

Looks like a little bit of a Hatsan melded with a Daisy/Winchester 1100s.
I don't know how much spring preload there is in this rifle. Probably less than 2"? I highly recommend using a good (purchased or DIY made) spring compressor until you know more about the internals.
The rear cap does not need to be pushed IN, just supported with enough pressure to take (most of) the spring preload off the large pin.
I have many springers similar to this and once safely strapped to my spring compressor with enough force applied to the end cap the pin can usually be pushed out with minimal effort.
A VERY FEW of my air rifles have a slight spline on one end of that main pin so it wants to come out only ONE WAY. Yours is not likely to be built that way so the pin should slide out either side.
Sometime I do need to TAP the pin GENTLY to start it moving but then it usually falls out under its own weight. For the tapping I use a short brass rod and a plastic head mallet. If that doesn't start the pin moving then I'm either not compressing enough or compressing TOO MUCH.
If the safety bar won't slide out of the trigger mounting bracket you may need to separate it from the plastic cap. That small pin in the plastic holding the parts together looks to have a larger head on one side so THAT pin will only come out in one direction.
Good Luck!

I doubt there’s much pre-load on the spring. It’s a 600 fps gun. I’m using a Rail Lock so no problem there. Are you saying just compress at the plastic housing that has the safety thumb lock and that might take off enough pressure to get the pin out? Main pin looks like it should come out either direction. I thought about removing the small pin that holds the thumb lock, probably should. If I get the main pin out the spring is going to push that plastic housing out when I relieve the pressure. Would be the wrong time to find I don’t have enough travel ha!
