Early V8 fan assemblies SURVEY

[earlyv8]

What years Ford V8s had generator mounted fans? I understand 33 thru 36, but I'm not sure.
Is there an aftermarket fan hub to modify a different generator to fan mounted fan?
Seems 8N Ford had a fan that mounts with 4 bolts that looks like a generator fan, but I'd be concerned with fan speed as the 8N had a low engine speed.
What is the best generator mounted fan to mount on a V8 to keep length short?

39 P/U had a generator mounted fan. You have to be careful of the tractor fans because they made some that push the air forward. There are also a lot of different "hub" lengths, that's the spacer maybe 2 1/2" inches in diameter between the pulley and the blades. You want the fan about 1/2" from the back of the radiator for better cooling. To far away and your pulling air from behind the radiator and not through it. G.M.

Try to find a fan from a 1939 Ford "standard". This will be the shortest as far as I know.
39 was the last year for the generator mounted fans

33-34 fans have a short hub. That is what I used on the 8BA in this 32 I am putting together.

The '33-'34 fans had a short hub compared to '32 but I think the shortest was '37 and up.

On the good side of an accident like that, your insurance will pay for the damage the fan blade does, but won't replace the fan itself.

That says it all. I had a 1950 Ford pick up truck fan blade work harden and break - going thru the hood and into the radiator.
The pieces just missed me as I was looking into the engine compartment.

I have been talking to Whitney machine about putting an alternator in a generator with a fan hub. I had a 40 2 brush with a fan pulley that I was going to use as a core. They told me that the front bearing was not suitable for a fan. I needed pre 39. The 37-38 model 78-79 generators have the best bearings.Older ones will work.

The ones I made have the Ford bearing and the 2 alternator bearings . G.M.

I do not know how they set up their conversion, but your way sounds good,plenty of support for fan.
