Fan for my 52 F5
 

Can anyone help me ID a fan for my 52 F5 8RT engine? I have an alternator with fan mount on water pump. I can't find which one or even something close. I'm not even sure what came stock on it. I'm pretty sure it was a four bladed fan. However, I have had no luck finding one. It looks like I might just have to do trial and error retro fitting. I can't live with the electric one that is on it now. It vibrates more than the engine.

I don't quite understand what setup you currently have. The flathead V8 (8RT) did not have a generator or water pump mounted fan. The six cylinder had a water pump mounted fan.

The fan setup for your F-5 should look like this (with either a 4 blade or 6 blade fan):

My mistake oops, but lots of confusion
 

You are absolutely correct, sir. However, I can't find any aftermarket sources for the four bladed fan.

I would think if the electric fan vibrates it has lost a blade or balancing weight. Usually, electric fans are quiet and pretty much vibration free.

The parts book actually calls for a 5 blade (18.5" dia) part# B7Q8600C. The parts book shows ONLY 5 blade fans for all trucks 1948-56, so I wonder if the 4 blade was supposed to be on the passenger cars.

38 Coupe, I see you changed the pic you posted, where was that one from, as it indicated the fan part # to be 8602?

Anyhow, Part #B7Q8600c

Dennis Carpenter has 2 NOS
Klimesh Motor Sales Calmar, IA 52132 has 2
Miller Obsolete Binghamton, NY has 1 $90.00

I think maybe the V8s are all 5 blade. My I6 is a 4 blade.

I was searching through photobucket for good picture that someone else had already made available. The earlier picture is actually a 1949 car engine, but the fans are similar. I updated it when I found a picture of a truck engine.

Here is the earlier picture:

The only 5 blade fan I have seen on a flathead was on a 53 truck motor and was definitely a one year only assembly.

Here's what the parts book list.... I found Van Pelts list 8602 as a fan/hub combination

This is what I'm saying
 

You can do a parts number search for it all day long and not get anything close. My local parts stores are worthless. Anybody have a Part #B7Q8600c
18.5" diameter 5 blade fan for a 1952 8RT flathead V8? Used condition would be fine. I have to ditch the electric fan!:'(:'(

So are you missing the whole assembly, including the hub and mounting bracket?

Just the fan
 

All I need is the fan. Anybody know where I can get one?

What was wrong with these (below)?

Or if you like that auction site:

Fan search
 

I called all listed sites and no one had one on the shelf. I bought the 5 blade aluminum one and pray that it will work.

I'm running a Car 3-blade fan with shroud and have had no issues even in 100 deg weather. But I have spent a lot of time getting my block and radiator really clean.

I have a four blade from an f1 and one from an f6. I need to look again but pretty sure the f6 fan has more than 4 blades

There was a thread about this about 6 months ago if you want a good discussion of it.

Anyone know size bolts?
 

Does anyone know the size bolts? I have located a matching 5 blade and have the metal ring, but no bolts to mount it on the hub.

8 No. 12-32 x 1/16"

Thank you, but I am measuring 1/4 " holes by 28 fine thread. Does that sound right? Are you saying that the screws are only supposed to be 1/16" long?

Am I reading this right? 1/16" long?

1/16" long? I measure 1/4" diameter and 28 fine thread. I have another problem. The pulley for the fan is freely sliding from mounting hub. Is it supposed to do that? If not, how do I fix it?

I'm sorry, they are 1-1/16th

No problem, thank you so much for the specs. I could not find them anywhere. Do I have a major problem with the pulley? It slides freely from behind the mounting ring aft to the motor on the shaft. Something just doesn't seem right with this?

Here is the list of screws and bolts for the assembly


EDIT: Just relooking at the chart, the 48-51 Big Job 337 fan hub had 1/4 x 28 thread x 3/4". Maybe somebody changed out the hub before, if so the parts list is just above the second group highlighted. I edited the picture.

I think your right, because it is a 239 and it had an electric fan on it. The pulley behind the hub is not firmly attached to the shaft. It does stop turning when I hold it up close to the back of the hub. It does look like there is a gasket between it and the hub.

The fans on these are opposite from most modern setups. The shaft is held firm, and the pulley/hub/fan spin on that.

I understand the spinning freely, but it slides back and forth along the shaft. The last thing I want to do is to put a belt on and throw the fan. It looks like there is a sleeve or something missing to hold it firmly on the shaft.

Yes, but the pulley is not held firm. It slides forward and back on shaft

Have you disassembled the hub and mount to see if anything is outright missing?

It appears that part 8603, the pulley, just slides back and forth and wobbles around on the shaft.

If it slides back and forth, either the hub assembly is not bolted together properly or the spindle bearing is bad.
As you can see in this illustration, the fan bolt goes through the blade, the hub cover, the spindle bearing and the hub. The bolts are secured by the 4 fan bolt retainers.

If it is bolted together properly and it still wobbles, the spindle bearing (#21A-8626) is bad. I went through this recently and found that there are zero spindle bearings available anywhere. I located a used fan assembly from a local guy, it was the last one he had. About that time I saw a couple of used fan assemblies sold on ebay, with the shipping they were close to $100.00

Great schematic, I tried to crank it up last night but it made a clanging sound and stopped. I do need to find a complete assembly, but until then I will have to go with electric fan again.

Harleymsn, you are so right! I did not have the retaining backing plates! You would not believe how many answers I got from so many supplier experts! I cranked, I bent the pulley so I need to find a complete minus fan. If you find one, please send link to it.

I found one on EBay for $60, but now having trouble starting her up. Acts like it's going to fire but dies then floods. I drain bowl start again and does the same thing. Any suggestions think my points are bad. It just started up a few days ago in 10 degree weather.

It sounds like the float is sticking open. Try rapping on the side of the bowl.
