Well, I have a problem here. I noticed the Harmonic balancer was wobbling when I started the car up the other day. Shut it down and grabbed hold of it. It was loose, so I put a socket on the nut and turned it and it moved without any pressure. I removed the front grill, radiator, belts, pulleys etc.etc........ The balancer unbolted easily and the keyway looks like the key sheared off and half is stuck in the balancer and the other in the crank. I can see two keyways clearly and the third looks like the other half of the key is sheared off and stuck there. (looking into the crank end from the front of engine it looks as if the crank had tree keyways) I need to remove the crank and haven't done this before. Can I remove the crank from below without taking the engine out of the car as I don't have and engine hoist ? The engine is a small block chevy.
