Ok, so how is the fan on my 239 flattie attached? There are no bolts or nuts on the front. Is it heated and then slipped on and when it cools it holds on tight enough?

 

Well, according to the Shop Manual, there are four bolts with lock washers that hold the four bladed fans on ALL truck model engines.

To remove the fan you are supposed to remove these four bolts and pull it off.

Not sure what is going on with yours. Rusted in place maybe? Non stock fan?

 

There should be eight bolts that hold the fan together. There are four slightly curved pieces, part #8642, behind the fan assembly that the bolts go into.

 

So check out the picture in my gallery I just added. There aren't any bolts on the fan that I can see.

 

can't tell from image what is behind blade attaching to block. appears to be a pressed on industrial style setup. what exactly is the problem?

 

I wonder if that could be an aftermarket fan. Flatties are known to run hot, maybe someone found a better idea. It could also be an industrial engine that used on a pump or sawmill. I'd try the Ford Barn, there's a lot of very knowledgeable flathead guys over there.

It's a car fan. They use a sealed ball bearing cartridge. Mine is a three-bladed car fan, this one must be from a Merc or possibly a car with HD cooling or even A/T. No repair is really possible. If you want to take it off the car/truck/engine, you undo the bolts at the horseshoe.

 

Oh man I'm such an idiot! You guys are right there's 8 bolts on the 239 truck fan. I read the removal procedure and looked at the picture and it's of the IL6 and that has 4 bolts. Point was though, there should have been retaining bolts if it was a truck fan.

Anyway, Ross is right, 52 Ford Passenger Car Shop Manual says: "The 8 cylinder [car] fan hub rotates on a sealed self-lubricated ball bearing."

The procedure for the fan removal from that Shop Manual is:

"(1) 8-CYLINDER FAN REPLACEMENT. Remove the screws retaining the fan bracket to the generator bracket. Remove the fan assembly and belt.

To install the fan, hold the fan assembly against the generator bracket and install the retaining screws finger tight. Install the fan belt. Adjust the belt tension and tighten the screws."

Sorry about the mistake - not unusual to have a few screws missing that late at night - LOL!

 

Hey, thanks all for all the inputs. It is a unique design. Just looking for a new home for it and wasn't sure if those parts separated or if I was missing something.
Have a great weekend...

 

That is a stock flathead fan, just riveted together at the factory. I think it is correct for the 59 series motors.
