trouble removing harmonic balancer
hey everyone, this is my first post. I have a 2000 f150 v6 4.2 and I am having one heck of a time removing my harmonic balancer. I have managed to shear a bolt from the puller off in the balancer. I attempted to use an ez out, but managed to shear off the dang drill bit inside the sheared off bolt. So far, i have removed the harmonic balancer about 3/4 of an inch.
I also attempted to use a pry bar of the back but just ended up destroying the teeth on that ring that goes around the back. So here I am, 3 days later and still unable to remove the harmonic balancer. Any suggestions?

I didn't believe it to be a bad one. I rented it from autozone, but as I later found out, I should have had a much longer bolt to put in where the original crankshaft bolt was attached. Since I didn't, I later discovered that I had been trying to pull the pulley against itself. I felt pretty dumb once I learned my mistake.

Perhaps there is some rust or other (gasket sealant) on that shaft.. I would soak that with some kroil or other sufficient penetrating product. It can't hurt. Re apply it between drilling sessions. By the time you are ready to reattach the puller you will be good to go.
Before you start drilling again, you need to use a small diameter drill bit or a punch to establish a center wherever you will be drilling so the bit does not 'walk' all over the place. Increase the drill bit diameter little by little.
IF, you end up trying to pry it off again, you will need another person or two. One to apply pressure with the pry bar whilst placing a large diameter hard brass/bronze drift pin on the crank center and whacking it with a 3-5 lbs hammer. But only as a last resort. If you have already moved it 3/4" this may work.
Question: why are you removing the harmonic balancer?

got it off
Good news. I got that bitch off today. I used a flat metal stake and stuck it across the balancer to hold the puller in place. I also found that in fact there was a large washer in there so once that was out, I just cranked down the puller bolt and viola! Also I replaced the faulty front main seal
