I started with removing the flaps that control the amount of air flow.
Not many of the screws survived (four on each flap device). Most of them needed to be drilled out.
This means a little more work later as the de-headed screws need to be removed. But at least they're out!
Then the generator with the attached fan was next. The book state four screws hold this in place but I only removed 2. Not sure if I have removed the others previously. The cover which can be seen below on the generator, was rusted to the shroud and had to be prized free.
The fan itself was straight forward. Once one end of the generator was in a vice and the 36mm socket was attached.
Now my pile of things to have rust removed is a little bigger.
