Yes, that diagram is on several web sites. It shows the big chunk 843 separate from 825. 825 comes off easy (don't loose the ball). But clip 54 seems to pin the rotor to 843. In a video of a similar model it looked like one expects 843 plus the rotor to lift out. The tail bearing 13 comes out with it all so it must just be a push-fit into the plastic back-end, as you can see that nothing much comes off there.

But mine is stuck. 843 is loose relative to the body but only moves about by 0.5mm or so. The rotor shaft does not wobble about at all at this point.

What the diagram doesn't show (well actually it does) is that all the wires are white so you have to be super careful taking the back end stuff off - but I have been here before.
