How do you take off fan? with out damage?
 

I need to take the fan off to put on the correct brass packing nut and the thrust collar. I ordered the hammer it puller with the other parts. Not here yet, Just wondered if any one has any other ideas. I have seen hoods were the fan came apart and I sure don't want to hurt the fan or the shaft

That looks like a original fan if so you should by a new alum fan. The original fans have a habit of loosing blades. Not good for the hood ,radiator or anyone standing by it when it breaks.

Screw that nut on the shaft half way then take a bolt and screw it into the nut
until it touches the end of the shaft. Now hold the fan near the pulley in one hand
and with the other hand hit the bolt head with a hammer and the fan will pop off.

Yes what George said.

First put a sheet of card board over the radiator fins in front of the fan.

Thanks guys, but now you got me worrying should I replace my original fan with no rust or marks on it that I can see with a new alum. fan? I have seen hoods with the slice in them but always thought it was rusty or abused fans that came apart. As much as I like original I have no problem with replacing original parts for safety if needed any advice appreciated!

Replace the fan.

Re: How do you take off fan? with out damage?
 

Yes, by all means, replace the fan.

A new fan is a small price to pay compared to getting beheaded

That looks like an accident waiting to happen! The rust outside is inside also!

Over the last 50+ years, I have mounted several NOS looking fan blades on my model A water pumps, only to find stress cracks in the blades a year or so later. I did loose one fan blade that not only destroyed my excellent '30 radiator and its water pump, but it also took the unlatched hood completely off the car too. The hood was ruined as was my clean underwear. I had my '30 model A rev'd out in second when a blade let loose with a loud boom. It was an ugly sight. The exploding noise was deafening. Fortunately, I didn't have a tow bill because this happened close to home. For years I refused to use Ford's two blade fans and instead I used the aftermarket four blade fans. Now I am a firm believer in installing the new aluminum fans. They look correct and work excellent. I also use their modern water pumps too. No more taking up on the old water pump packing. :)

Its unanimous! I will order a alum fan! who sells the best one or are they all made by the same manufacturer? thank you all for your combined experience!

Re: How do you take off fan? with out damage?
 

Smart move. You can always clean it up then hang it as an original manufactured part.

Re: How do you take off fan? with out damage?
 

Only one maker that I know of.

I put in my order for a new snyder"s alum fan thank you all

From a technical standpoint the original fan is a sheetmetal weldment. After studying how it was made the people over at ford did a remarkable job of design and fabrication. However they didn't pay attention to how the fan operated mechanically in the engine and it's life exspectancy. In operation the the fan blades flex or bend and pulled outward as the speed of the engine changes. These conditions are not visible to the naked eye but over the years of operation this probably has occurred many billions of times. Welding two pieces of metal together produces tiny cracks in the areas around where the weld meets the metal. These are called microcracks and can grow larger if the welded area is subjected to mechanical stressing like pulling and bending. Continuously pulling and bending of the fan blades while in operation is the mechanism which causes the cracks to grow to the point where the metal joint fatigues or completely fails and breaks apart. Corrosion within the cracks also helps to speed the process along.
What amazes me is to see how long this part has survived while operating under the conditions it has been subjected to. A modern day analytical engineering analysis would rapidly indicate the life of this fan design is very limited.
I highly recommend replacing the original fan with a one piece fan especially if you like to drive your A and do touring.

I don't think in this case you'll need a carboard because the water pump is oout of the car

Re: How do you take off fan? with out damage?
 

I'am glad Iverson made this post I did not know this about the weak fan blade.I will pick up
an aluminum fan next order. I had that happen on my T with a new radiator not fun.

Re: How do you take off fan? with out damage?
 

I had no plans to replace the fan until all the good advice thanks guys! I am putting on a original funnel top radd and fan shroud that I got thanks to the ford barn and a brass packing nut who knows? maybe the original fan failed some time before my uncle got the car in 1951? and I keep everything I can original down to the nuts and bolts

Re: How do you take off fan? with out damage?
 

Good move replacing that fan. You'll never know how long the old one would have lasted but you can rest assured, it would have destroyed itself and who knows what else sometime soon.
When I bought my '29 Phaeton, it had an original fan fitted which I decided to replace before it took the decision out of my hands. Inspection once it was removed showed that cracks had been brazed up everywhere, even around the bottom of the vee in the pulley. I still shudder when I think of it.
