when the motor is hot, the crank is also hot, and thus would expand and take up the slack created by the HB expansion. The theory is to pu the balancer on hot, with the crank cold.

Works great for bearings, so why not? Thing about heating bearings for installation.. ya gotta get them on FAST 'cause soon as the shaft pulls the heat out of 'em, they shrink back down.
