I can send you a bunch more pictures I took when removing the magneto out of my KG9, but these might tell you everything you need to know.
I took every bolt off the magneto body, probably didn’t need to, but I effing did it anyway. But basically, once the top gear is off, the drive-key removed, and the sleeve that fits underneath the gear is taken off, the magneto shaft should be able to be pushed out of the bearing. Shaft is a snug fit in the bearing, but you can tap it out, just need to be careful and not whale on the thing like you’re chopping down a Sequoia
Hope this helps
Best,
