How do you remove the Dynastart fan?

I would like to take the fan off the Dynastart so i can clean and paint it whilst I check on the brushes. I know it is locked to the shaft with a key / keyway to make it rotate with the shaft. I don't think you can get a puller on it as the fan blades overlap.
So how do you take it off?
Regards,
John

Mine just came off once I got the nut off

How long has it been on the Dynastart? Mine is likely to have been on the shaft since 1983!
Jim has put forward an official method - Use a puller that screws down the center of the fan. Or a system that uses the weight of the Dynastart along with a hammer and drift to tap the shaft down through the fan.
I'll take the Dynastart off and have a good look at things on the bench.

Sounds good
I am not sure how long mine was on for as I have only owned it for 3 years
Guess I was lucky (to bad there are 100 other parts of the Hafi that I was not lucky with)

I sprayed mine with a penatrant, then just grabbed the shroud and shook it up and down letting the weight of the dynastart act as a slide hammer until it came off took maybe 10 min. Make sure you put some grease on the shaft before reassembly so it doesnt happen again.
