How perfect should the S/C pulley be when spinning? I recently purchased a used one and noticed it appears bent. It wobbles when I spin it. I've not put a dial indicator on it to see how far out it is and I never spun my OEM pulley before I bent it to see how perfect it was. I'm pretty sure this was taken off with a s/c pulley removal tool, but after seeing this, I wonder if the only good way to remove one of these is via a press.
