Fans

[qmdv]

I think these are model A fans. I need to identify before I list them. They mount on a tapered shaft

pg98 volume 1 of MAFCA's How To Restpre Your Model A tests 4 types of fans for cooling.
They test a 4-blade & refer to it as a truck fan.
I forgot, did the A truck or AA have a 4-blade fan?

I have never heard of an A or AA truck coming from the factory with a 4 blade fan. I have never seen a Model A part number for a 4 blade fan. The '32 four cylinder engine used the late 1931 Model A fan. In 1933 the four blade fan came out (46-8600) and was used through 1934 on the 4 cylinder vehicles. The Green Bible shows part 46-8600 used 1928-1934 as a replacement part.

Thats what I thought. The article just says "4-blade original truck fan", which implies original Model A but doesnt say that outright.
And this is the original "How To Restore your Model A" 2nd edition from 1967 so who knows when that article is written. Great info on temperatures eg cylinder #4 running hotter. But this was way before lots of modern research so maybe there was an Urban Legend about a factory 4-blade.

Green Bible is that the original Price List?
Mine's from 1932, shows B-8600 for $1.10, and 18-8600 for $0.85 or about $25 in today's paper dolars.

The "Green Bible" was the parts list used by the counter men in the parts department in the fifties showing the early parts. Ford assigned part number B or 18 for all parts used in 1932. This included renumbering parts used on the Model A. That explains why you see the number B-8600.

These fans look like they are rusty and probably pitted. Fans like these that are rusty and pitted are prone to failure.

I would not list them for sale, I would use them for wall hangers to decorate your garage.

My opinion,

They could be checked for bad rivets or cracked blades, if they are OK they are safe to use on an engine.

I believe that most engines for binders that used the Model A engines came with the 4 blade fans.
