Fan too far from radiator. On my 32 build I have a 59AB engine. My fan is 3 inches from radiator. What some call the fan hub is 1" long. I think 1" fan clearance from radiator is what I need so a fan with 3 inch hub would be ideal. Since I have been having trouble finding one I think a 2 inch spacer (easy to make) would solve the problem. Anybody do this.

Re: Fan too far from radiator. The '32 fan is 4 1/2 from the from of the blades to the rear of the hub. That might be what you need. If that doesn't give you what you need one from a '33-'36 might work. The dimension for the '33-'36 is not in the green bible, maybe someone can provide it?

Re: Fan too far from radiator. Sounds like you have a 33-36 fan. These have the shortest hub (about 1") of all the generator-mounted fans. A 37-38 fan hub is about 1 inch longer.

https://www.fordbarn.com/forum/showthread.php?t=253607 I responded to your wanted ad for a 37 fan, but you declined that, and said you had decided to make a spacer for the fan you already had, which is apparently a 33-36 fan. I'm sure many folks have done this in the past, but it seems to me finding a fan with the correct spacing hub would be a better option. |

Another problem you might have (not related to how close the fan is to the radiator) is the height of the generator/fan as determined by the intake manifold. If the generator/fan is too high the fan will hit the hoses. The '37 (and I think a few years later) is the lowest. PM me if you need one.

The big picture is of a 37 V860 commercial fan.Here a pic of an original 32 V8 Fan(attached thumbnail).The hub itself is 3 3/4".The '32 from the front of the blades to rear of hub is 4 1/2".'37 commercial fans look similar and that hub is slightly longer( 4 1/8") so for the most part might not clear the radiator depending on the core thickness of your radiator.The 37 commercial fan hub has a longer collar at the flange where it mounts to the generator.That is the quick way to tell. https://www.jalopyjournal.com/forum/...1-jpg.3479647/ |
Re: Fan too far from radiator. Deuce Lover, what is the diameter of that 37 fan? I thought the 36-39 commercial fans were larger (17") than a 32 fan.

Re: Fan too far from radiator. Check Stokers Hot Rod Factory. They manufacture a series of Flathead fan spacers. I know they're for Hot Rods but they look really good and I'll bet they work.

That I couldn't tell you but you are correct about the 17".The 37-39 V860 commercial fan is 15 3/4" with a 4 1/8" hub.That was a fan advertised as a '32 on another site which was incorrect..I added that pic so that one can tell the difference of the hubs. |
Re: Fan too far from radiator. The 37 passenger car fan has a 2" hub riveted to fan blades. When you factor in the pitch of the blades it's overall measurement becomes nearly 3" which I said in my pm to you. What you've needed to give us from the get go is the actual measurement from fan mount pulley to finned radiator surface with radiator mounted in it's exact final position.
Also, as you take the above measurement, you could measure what diameter fan blades must be to prevent blade tips from hitting underside of top radiator tank. |
Re: Fan too far from radiator. TURLOCK SWAP MEET this weekend. I will be there with all the necessary measurements. AS usual there is a lot of good info and smart folks on this sight.

Re: Fan too far from radiator. I was in the same situation with my 32 with an L.B. engine and had a spacer made to give me the distance I decided on. Easy fix with a piece of AL, Worked for me. kerk
