1964 5-Blade Clutch Fan

[Logan Robb]

My 64 Fleetwood has a 5-blade thermal clutch fan, the seals let loose and I could see into the bearing and the oil or fluid let out as well. 

I just wanted to pass along some measurements to save someone a little time in the future. 

The opening on the fan itself is slightly larger than 2 1/4". The shaft of the clutch is exactly 2 1/4". So if you intend on replacing the clutch, make sure that the shaft on the NEW clutch will fit thru the opening on the fan. 

I ordered a "Severe Duty" clutch from Rock Auto, part #930-2010. The brand was FVP, but I've seen that part # on other brands as well. The shaft diameter was 2 1/2". A whole 1/4" too big. Rock Auto said this would work. I was skeptical, but figured I would give it a try regardless. 

There would be no way without major modifications to either part they would fit. They are not compatible. 

I made the choice to find a non clutch 7-blade fan. I can always go back to a clutch fan if needed. Ill keep the thread updated if I notice any major difference.

Also, I was able to remove the two radiator hold down bolts letting the radiator shift forward slightly, this allowed me to get the clutch fan off the front of the motor without removing the cooling shroud. Not that it is hard to do, but the less to remove the better.

dont know if this applies, but there is a guy the rebuilds these clutch fans,,,right off, dont remember his name, does corvette stuff.. had it done on. a rebuild I did.  ran about 500.00  I was shocked,  but, its an option if you so desire

I don’t think I’ll be rebuilding a $50 part for $500 HA! There’s got to be a reason the cost is so high..,,

yeah,  I should have asked but I had no. idea it would be so high,, but, I guess I can assume its ok.. if price = value.  good luck with the method you choose,,
