While using a tool especially designed for "bolt" dis-assembly is the easiest way to work on your bolt. Most of us don't have one.
The only bolt work I ever done was to "potty train" a couple of mine......, this involves clipping the spring to have the ejected rounds land in a small pile, for easy retrieval after firing.

Here are some tips:
1. Complete removal of the ejector pin, (4) is not necessary, as when pushed far enough out the bottom of the bolt, both spring (6) and pin (4) will come out.
2. As without the dis-assembly tool, ya need 3 hands, suggest ya have a friend handy to help.
3. Use a spent round (the brass) and place into the bolt to compress the ejector, this will remove pressure from the pin (4), making it easier for your friend to tap the pin far enough out the bottom to release both spring and pin.
4. Notch on ejector faces out, toward the true "left" side of bolt, when re-installing spring and ejector, flip the bolt over and while again using a spent case, hold ejector in and have friend tap pin back into place.
Hope this is some help,
