I apologize if this has been answered 100 times before. I did some searching but couldn't find my answer.

I'm trying to pull my harmonic balancer off a 54 235 engine. The two holes in the front off the balancer aren't threaded and the center off looks like a giant phillips screwdriver. The other 5-6 bolt (???) holes look like giant nail heads. I'm stumped on how I get pressure on the balancer to pull it off.
