Let me catch up. I trimmed about 5/16 in. off the long end of the hoses ans re-installed the trimmed ends on the pumps as Kube suggested. I laid the fan face down on a flat surface and found some of the blades "bent". the short blades were the worst. I began tweaking the long blade until the leading edge of each blade was even with the surface. Then I did the same with the short blades.
Each long blade is across from a short blade. This distance is about 16 in. measuring from the center of the hub to the end of a long blade would make the swept dia. between 17 and 18 in. I think.
I agree, Kube, I won't have to space the fan closer to the radiator. I can hold 2 paint sticks on the hoses ( where they were contacted) and the blades clear while cranking with the starter. 2 paint sticks = about 1/4 in.
Sorry, no videos while cranking; I don't have enough hands.
