Reinstalling a metal 4 blade fan on a 1936 car, (had a 6V electric fan, pull type ) the fan I came up with when installed on the front of generator is to close to the radiator hoses. ( like a gap of only a 1/8" ) Need to know what is the correct length of hup/spool portion of the fan. I looked at search section of early V8 forum but did not come up with an answer, lot of info but not exact, thanks Bruce

The 35-36 book says the fan should be 15 1/2" dia, 1 3/4" deep.

I found a 2" fan hub, that is measuring from back of hub ( generator end ) to back of nearest fan blade. The 2" is to long, the one I have measures 1 1/8" ( to close ). Need to know where the 1 3/4" measurement is taken from, Duece_Roadster, any idea. I believe if 2" is to long that the 1 3/4" would be correct, need to find one, any info or location would like to know, thanks Bruce

This photo is of a 36 fan on the genorator. I am not sure we're to measure from but this should be right

So Don, since you are co author of the 35-36 book, is that a misprint on page 103?

Deuce. The 1 3/4" dimension referenced in The 35/36 Book was an overall depth dimension from the base of the fan hub to the center fan rivet.

What Don is showing here is the most critical dimension to have or know when making sure you have the correct fan that should give you the correct clearance. If it doesn't, then something else is located incorrectly, IMO.

Be sure your fan belt is not too long. With too long of a belt it can cause the clearance to be awfully close with the hoses.

Thanks for clearing that up Don, I think your diagram in post 16 is what Bruce wanted to know.
