Harmonic Balancer Install

Place the balancer onto the snout by hand and then thread that all the way into the crank snout. Slowly start to turn the nut down and it will pull the pulley onto the crank. Just an FYI, these aren't really balancers since the crank is internally balanced. More accurately it is a dampner/pulley.
