Sadly I've done this on a 78x593 but can't remember how.  The yoke as I call it has to little screws I've removed from the collar but the yoke doesn't come off and I know there are ball bearings inside this part of the support.  Is this pressed on or is there another retention method I'm forgetting about?  I've included a pic of the part where the oscillation level attaches to.  Not where the lever attaches to the gearbox btw.  Hopefully someone has done this AND remembers unlike myself.  Thanks to all.

Are you wanting to remove the bell shaped oscillator disc under the gearbox that the oscillator linkage is connected to?  That is pressed on and is made of pot metal.  Trying to remove it may cause breakage so best to leave it on there.  I can't think of ball bearings anywhere on your fan.

Hello Steve.  No not that part.  If you look at the motor case and the post it is on, it would be that part.  See the pic I've sent below.  That post comes off some how and two bearing are inside.   Also, tips on gettings this stator out.  It sure seems to be my toughest one so far.

Well, got the stator out okay so no help needed there. My other GE fan which is a 1941 Vortalex allows me to remove this stub pedestal. This one not so it seems. Makes it a pain to clean and refinish due to this.

And that is where there are ball bearings, in the stub of the pedestal swivel?  If the bearings were put in there I think there should be a way to get to them.   Not having worked on such a "new" fan I'm afraid that I can't help you without seeing the fan and tinkering with it myself.  Those swivel necks can give some hard to figure out problems.

I'm going to reexamine my other fan that I got to these on. I think on that one there was a pin to remove after removing the two little screws on the collar. I think. Will follow up on this one but even so I don't see a pin with this fan which is a few years older.

I don't think there is a pin to remove. Likely what's happening is the Bearings are just stuck. Try applying some penetrating fluid and let it sit awhile. You might try to apply a little heat to the housing, but not too much as it may be pot metal.

Hello to all who answered. It did take a little heat to get things going in the right direction. My memory fails to often now and I was visualizing a pin to remove but the pins are on the inside and hold the bearing in place on the stem. Just heat and a friendly persuasion to pull off the housing. Thanks to all and what a group this is.
Also had to add these photos as to the major difference in the finish once I removed paint.  This of course is the gear box.  Notice the lid versus the box.  One is polished or chome plated and the other just pot metal.
