There is the retaining pin in the head, pull it out the head should spin freely without the pin and indpendent of the shaft. Then theres the links that hook the swash to the flybar control frame, diconennect them from the swash plate and take the head off. The undo the ball joints on the swash plate so it moves freely. If you can lift the swash off easily then you'll need to sand down where its sticking, for me the hole near the top where the pin goes in. Once thats done theres a retaining collar on the shaft, loosen the screw and take it off. And pull the main shaft out from the bottom. If you didn't sand down the shaft earlier you problly still stuck with the swash on, just get a good grip and yank till it comes off. then use a pair of pliers or some similar, and put the top of the shaft on a hard surface and the pliers above the bearing thats stuck and just try to brake it free, once thats done the shaft will come out with a bearing from the other side, do the same for this bearing.

I think this is detailed enough to get you threw it. Remember its gonna be like this for every bent shaft.
