How the hell do I get the harmonic balancer off?

Im installing underdrive pullies and just need to do the crank pulley now but I cant get it or the harmonic balancer off.

I removed the center bolt and Im using a harmonic balancer puller but I cranked down on it as hard as I can and now the crank turns with the puller.

Is there something Im doing wrong?

Im not even sure that the harmonic balancer needs to come off but the pulley wouldnt come off by itself. Does the harmonic balancer even need to come off?

Got it. Thanks for the help.

BTW, I did remove the HB bolt and washer.
