So I was going to install a gear drive yesterday. I went to remove the large center bolt that holds the harmonic balancer to the crank shaft, and it was loose..hmmm i thought. So i reached in with my hand and pulled it right out.. The threads are compealty gone on the first 1/4 inch or so, and its all stripped out.. So how long will a harmonic balancer stay on with out that bolt? I'm hopeing that since the balancer is pressed on there pretty good, and the fact that you have to use a puller to take it off, means that it will stay put.. What do you guys think?
