I'm changing my crankshaft position sensor on my 1998 Chevy Blazer LS 4x4 and im stuck. I'm trying to remove my crankshaft pulley but I don't know how. How can I get it off and then put it back on?

1st you need a puller to remove the harmonic balancer and also prevent the crankshaft from turning to remove the center bolt-

I've removed the harmonic balancer already, I just was stuck at the point on how to remove the pulley itself.
