I need some help to Ford historians to determine how the factory balanced the engine's rotating assembly during Model "A" production. What I guess is:


>Pistons & connecting rods were individually weighed and sorted into sets by weight;
> After assembling with wrist pins & rings, the assemblies were weighed and sorted into sets by weight;
> The crankshaft was spin balanced by itself on a table atop springs. No weights were added to the crankshaft throws to account for piston assemblies, friction, etc. Holes were drilled into the crankshaft until the table's motion met a prescribed amount;
> The flywheel was statically and dynamically balanced without the clutch.
> The clutch was balanced by its supplier.


Is this the way Ford did it?
