I work with a company that produces harmonic balancers. They are highly engineered pieces to cancel the frequencies that the engine produces. Just the wiggling of the balancer to pull it off the crank, can damage it.

do not reuse this balancer, take everyone's advice here. You are asking for trouble if you do reuse it based on it coming apart.

I have seen an engine blow up due to a failure of a harmonic balancer.
