I used loctite 271 to seat the bearing. It seems to have worked great.
When I went to press the front bell off of the rotor I got distracted and broke the fan. This is ironic because I think I just sold my last extra. Man, some days...
I was wondering just the other day why so many people are looking for these fan/how they come to be broken. Now I know :-)
I'm not totally sure at this point if this saw was meant to be re-built.
