I'm trying to replace my crankshaft position sensor on my 2000 Pontiac Grand prix and in doing so obviously need to take off the harmonic balancer to get to it. I've got the huge bolt off and rented the pulley system from Autozone. I had to go and buy the right bolts and washers to fit into the harmonic balancer (hb). The pulley kit I rented came with a cone shaped metal piece that goes on the end of the black pressure screw to push out the hb. In my stupidity and ignorance I noticed that the cone was too big but didn't know it wasn't supposed to be so like an idiot I started tightening it down and now have gotten that piece stuck in the hb...and it won't budge out for anything. I just need an alternate way to get the thing (the hb) off as I need to replace this sensor so that I can drive this car to work. Thanks ahead of time for any feedback.
