I did the same thing while getting the original off. I don't remember having to lock up the new pulley. I did make one mistake when putting the new pulley on, I forgot to put that large washer on the bolt. The crankshaft kept turning and wouldn't pull the new balancer on! As soon as I got the washer on, it pulled the balancer on.
Do you have that installer to pull the balancer on initially?
