Default Three-Blade Fans

I know earlier Ford fans and hubs are serviceable. You can disassemble them relatively easily or pull the little drain plug to fill them with oil, but is there any way to service the later 1950 and up three-blade fans? Iím looking at one on my workbench right now and it looks like it has sealed bearings. Can it be rebuilt? If so, how does it come apart? Thanks in advance!

They come apart if you have a press and they used a relatively common water pump bearing (I can find the number if need be). I replaced one on my '51. You have to cut the shaft on the bearing down to the correct length and them press the whole thing back together. I tried to do it with my LARGE bench vise, but ended up taking it to a friend who has a 20 ton press.

Yes, Tubman, if you could share that info I'd really appreciate it. I'd like to make certain the bearings in the fan I'm eventually going to run are as good as possible. Also, do you have any instructions/tips for pressing the assembly in and out?

Perfect! Thanks so much for digging this information up. Looks like you can get one on Amazon.com for a few bucks less than eBay: https://www.amazon.com/885586-Integr...dp/B004OENCQC#.

More info here: https://www.fordbarn.com/forum/showp...0&postcount=10

PS I would not buy the cheapest bearing, I'd get a genuine NSK from a bearing dealer.
