Removing harmonic balancer on a 250
I was at the junkyard this morning looking for power steering parts. Found a nice gear and pump (though the pulley is bent -- that I'll get from GM), and the extra-slot water pump pulley. I found several harmonic balancers, but I COULDN'T GET THEM OFF! Every one is the "press on" type with no bolt. They seem to have a nice tapered seat that looks DESIGNED for a standard three-bolt harmonic balancer puller. But when I put mine on, I couldn't budge it. I got it as tight as I could, and then the crank started turning.
It felt like the Ford ones do when you remove the pulley bolt, and you end up pressing AND pulling the same piece of steel. For those, you reinstall a few threads of the bolt, and press against the bolt head. But these HBs dont HAVE bolts.
What am I doing wrong?
Also, are these HBs keyed, or can they be installed in multiple orientations?
