Thanks to everybody who responded. The part number in my Factory
Olds parts book for the F-85 flywheel is 586998. This is not the same as
the Buick part number given by James Brown (1350947). The pictures and
descriptions supplied by various people for the Buick Special wheel are
certainly very different from the flat F-85 wheels I have and have seen. I
wonder if the clutch parts are the same? F-85 numbers are 1347564 for the
cover/pressure plate and 1355747 for the disc. Are either of these the
same as what you have for the Buick, Jim?? BTW, there are several other
numbers in my book for Police, Taxi, and Jetfire (turbocharged engine)
flywheels and clutch parts, but they are surely very rare.
Then Kent comes along and says all F-85 and Special flywheels are
the same and that the flanged ones are from the 62-63 Buick V-6. This was
the first Buick V 6, was 198 cubic inch displacement, and was odd-fire. It
seems reasonable a heavier flywheel would have been helpful in smoothing
out the power flow, but my understanding has always been that these 198
engines were produced only in very small numbers. If this is so, how could
so many people have these "rare" flywheels?
Lastly, the "flywheel" for the F-85 Rotohydramatic transmission is
as I and Kent have described, but there is indeed a torque converter in
these transmissions. It is inside the main transmission housing and very
small in diameter, not external and bolted to a flex plate as we see in
other instances, including the Special. Presumably it was not heavy enough
to provide a flywheel effect by itself, thus the external weird-looking
flywheel and spring-center disc.
