I am disappointed to learn that I have to remove the radiator to get one of
the fan motors out. At least I'm finding this out BEFORE I start the
project.

Today I squirted some white lithium grease into the hole at the bottom front
of the motor. Before it "chirped" every time I spun it by hand. When I was
done, it chirped about every 10th spin. I since took a 60 mile trip today
and I think I only heard it squeak once, but I'm not sure. Before I oiled
it, it would have a squealing attack about once every 20 miles.

Can anyone say how these motors come apart? It looks like they should pull
apart if you remove the two nuts on the back, but I check the archives and
someone said that this didn't work. Since John Hervey is selling rebuilt
ones on his website, I figure that it is possible. Maybe I'll just let him
do it; although, that wouldn't be as much fun as doing it myself. I am not
enthusiastic about buying one from a vendor for $260 when I can buy
something aftermarket for $180 less that will probably work better, i.e.,
use less current & have a higher CFM.

Does anyone know what the specs are of the OEM fans? How many CFM do they
move? Summit Racing has model PRM-19010, a 10" fan, 1,250 cfm rating for
$80. Since I'm planning for a lot more horsepower someday (an engine swap)
I want all the cooling I can get especially considering all the customizing
that Bob Brandys did with using larger radiator pipes & such on his
conversion.
