I did a search but couldn't come up with an answer.

I've recently installed a 4 blade fan on my 30' Model A after seeing a major crack on my original 2 blade.

Installed, the fan hits the radiator.. I am at a loss, Is there a way to bring the radiator forward? Or bring the fan back? :confused:
 
If this is a new 4 blade fan having a cast iron hub and pressed steel blades held together by 4 bolts I wouldn't fit that either!!!
I have had one of those fly apart and take out the radiator and the water pump
Best bet to use a cast ally or plastic blade one

Go back to a 2 blade! lol Serioulsy though, I love my new aluminum 2 blade. For around $40 you can't beat it. And it looks like it belongs to boot!
Good Luck whatever you decide, D Lazaris.
 
I had that happen and it turned out that the keyway hole had broken and was allowing the fan blade to wobble which allowed the fan to "hit" against a part of the radiator as the blade rotated.
 
I worked on a 39 Ford with that problem. Turns out the fan was for a truck, and the blades were longer than one for a car, so they hit the lower radiator core.

ever try to replace a water pump equipped with a 4 blade?? the radiator has to come out. With a 2 blade, it does not. The advantages of a 2 blade out number the 4 blade in performance, fit, appearance, and cost.
 
Try loosening the radiator mounting bolts and move the rad forward at the bottom?? Are the blade lengths the same on the 4 blade as the two blade?? Fan "seated" on the w/pump shaft??
