fan application help Q

[hardtimes]

I just bought a water pump, with a custom made 'spacer/fan attachment part'. This is the mid thirties type pump that are used/adapted to use on B head/block.
Problem is I need help figuring WHAT fan did adaptor maker intend to use ? None I hade fit mounting hole pattern ?
I'm going to try adding pictures now.




What has happened to prevent me from showing pictures now ??
Use SAME process as before (maybe 2 months ago) and never had a problem showing pictures. ANYONE know ?

i think you are talking about the adapter to use a 32-36 water pump, on an A head. i have one, but sorry i cant remember what fan i used. i know i started out with a 2 blade fan from a 20's chevy i had, and it did not cool well. i then found a 4 blade fan with the same pattern from a.....not sure, but model a truck, or aftermarket thing. sorry i cant help better! i believe cragar made those adapters

Thanks for sending me the pictures. You should be able to post the ones I returned to you. The spacer was probably intended to put the fan in the correct location for his project. My guess is that the guy had a '32 fan with a long spacer so he punched out the rivets and made the spacer the length he needed. I bet that any Ford fan blade could be used by punching out the rivets and using bolts to attach it to the spacer, but I don't have one to check. I wonder how the water pump bearings will hold up under the load of the fan? That holds the spacer to the water pump pulley?

Hey Bob,
Basically same pump and fan holder arrangement.
NOW, thanks to Charlie, I can post the pictures that I tried to before. As you will (hopefully) see, the fan adapter on front of pump is about 1 1/4" thick aluminum. Bolt hole spacing specs will also show if pics show.


Well, found out from Charlie's information, WHY my pics not posting now.
I recently used an Iphone for pics. Resolution/pics...tooo good/big to post.


So, now that that is happily figured, here are pics from old camera chip way:


THANKS CHARLIE FOR HELPING FIGURE THIS OUT !!


Bob, what is that pictured fan from and is it a vendor product ?

The 4 bolt pattern was used by GM to attach their fan in the 1960-70's. I checked my Chevy II engine and the spacing was too small. Maybe a bigger GM vehicle? You should be able to go to a parts store and check a couple of water pumps for the pattern.

Hey Charlie,
You gave me enough feed back to let me figure out WHAT I had changed...I.e.-camera to iphone. Since I haven't a clue about how to reduce iphone pics, I'll just re-use old way Canon camera.


I do have Cyclone and other adaptors such as Bob shows in his pics. That is not the subject/problem. As you will now see from my posted pics, the alum adaptor for fan BOLT HOLE spacing is my problem/situation.
I have model a two blade fan (two blades which bold together) from vendors, that have tooo wide spaced holes.


Also , if nothing else pans out, will look at your idea of taking rivets from a fan to try pattern of fasteners.
Your comment about durability (stress/strain on bearings)of this type mod, is well to consider !
This pictured setup was obviously run before I got it in Bakersfield this past Friday. The bearings/shaft in pump appear to be very solid / tight. And, adapter seems to be machined / centered well. We'll see , as I'm going to run it , if fan can be found for it.

Thanks, but I have several different old adapters such as you are referring to.
That is not the problem. Thanks for your FAN app references, may help there.
