It seems you may have come across one of the Flathead "secrets". Most discover that the Ford Flathead Fan Hubs require motor oil the hard way when they start making noise or seize up!

I oiled the fan like the directions given in the link. The fan turns freely both by hand and when I turn the engine over my hand. I got a little oil on the belts. I wiped it off it doesnt seem to effect the belts moving. I am going to give it a try again today.
I disassembled the Fan hub (Honestly I was pretty proud of myself). It was a mess inside. Looked every bit of something that is 75 years old. One gasket was completely gone and the other fell apart pretty easily. A friend suggested soaking in gas or diesel to clean up the parts. Thoughts on soaking in gas or diesel? I have new gaskets coming this week.
I took apart the fan hub. Replaced the gaskets, really cleaned up the all the parts, added oil. Fired it up. The fan turns while it is cranking but stops once the engine turns over.
What else could cause the fan to lock up when the engine is running?
Okay, if the fan hub assembly has been properly lubricated (both earlier and now) and it still gets stuck, there are a few thoughts that come to mind:
1) Proper Fan Belt, Adjustment, and Alignment
2) Damaged components:
Is the 21A-8632 fan bracket complete, whole, and void of cracks?
Is the 21A-8626 fan spindle bearing fitted to the shaft without any side to side or cocking motion?
Is the 8RT-6520 intake manifold / valve chamber cover cracked or missing pieces where the assembly registers?
