I pulled the retaining clip from the bracket and expected the shaft to come out easily. I used a plastic hammer and tapped on it and then hit it harder. Nothing. Should I use a puller?

Pressing it out will be easy, pressing it back in might be a challenge. I think I will refurbish it as is. More work getting into the crevices but six of one half dozen of the other kind of deal.

Joe: Steve is right, the fan bearing should be pressed off. Since you are doing so much great work to bring your car back to original and especially if you intend to drive it when finished, I recommend you press on a new fan bearing. That old bearing is a sealed bearing so any lubrication left inside that bearing is almost 75 years old. The same is true of your old axle bearings. Original sealed bearings to the car need replaced. Find a machine shop with an arbor press and they can press on that new bearing so that the locking safety wire that you pulled off will slip right in the grove of the new bearing.   Bill

Very good point Bill. I have a press here. I will mark the fan mount and take it all apart and then reassemble in the same orientation so I don't throw the balance off. Get a new bearing tomorrow morning.

I cleaned and took a look at the bearing. It appears to be modern and turns quite freely. I decided to leave well enough alone. It's an easy thing to change later if required.

As Bill suggested change those axle bearings no matter what you see or how they look.  They are cheap and can be purchased most anywhere.  These old sealed bearings are not good and fail regularly on tours if they have not been changed.  Unless you are really sure about the fan bearing being new the price is very cheap compared to a fan in the radiator.  The original old ones look just like the new ones

I tried to respond earlier from my phone but for some reason it wouldn't post. Changing the wheel bearings is one of the very first things I did when I got the car. I will change out the bearing in the fan, just later in the winter after the work I have planned is complete. Pulling the tired engine out of the car tomorrow and then starting the cleaning of the engine bay.
