Thank you so much Quinnbrian, I was able to dissasemble following the video and taking the magazin catch off first.
The assembly was still full of cosmo and corrosion but the real problem was the safety pin was not set in the safety spring fork right, so the fork spring was not in the right position.
Thx for the tips and support guys.
And just for general information most of the videos in the skickies don't work anymore.
