I'm working on removal of the fan so that I can disassemble the motor. It appears that the fan is threaded onto the motor shaft in addition to being held on by the nut. I was able to remove the fan nut successfully and it is standard thread. I don't want to damage anything and I am looking for a way to hold the motor shaft while unscrewing the fan off of the shaft. I don't see the access holes in the side of the motor that I've seen on the newer Royals. Is there a trick for holding the motor shaft while removing the fan? I have worked on a few old Emerson fans and there is an access hole to a spot on the shaft where a screwdriver can be used to hold the motor but I'm not seeing anything on this motor. Thanks
