Getting harmonic balencer off

Thank you for your advice. I figured out there is a roll pin of sorts on the crankshaft sprocket that fits into the balencer. On mine it was rusted on some how. But nothing i read said anything about that pin even when I talked to the hyundai guys at a local dealership they said it should just wiggle off

That’s the locator pin for the balancer - make SURE you install a NEW revised crank bolt and torque it to proper specifications.. Crankshaft damage will occur if this is not done.. Do not try to re-use the old crank balancer retaining bolt!
