I found that you can actually get the fan off and I did to understand why the motor failed
Lots of penetrating oil and you can clamp the pulley and twist the fan off
Whan I pulled the fan and pulley off I found why the motor failed .
The motor apparently jammed because the belt was against the condensed and heated up to the point that a solder connecting an internal choke melted and the choke lead sprang out of the connection.
After resldering the choke The motor Ran but I'll replace it anyway because the brushes were shot and I didn't want to deal with ballancing it
