Jim,

I misunderstood; I thought you meant the good engine shops used the flexplate and harmonic balancer to balance the rotating
assembly.

I agree good engine shops balance the crank on it's own (taking into consideration the reciprocating weight), the flexplate on it's
own; and the harmonic blancer on it's own.

That is correct, Rob. But the "fussy duck" engine balancers do the steps I
mentioned, in addition to the crank, rod, and piston work. Nothing is left
unbalanced except the owners checkbook. (Grin)
