440 harmonic balancer removal

I've also used 2 longer bolts in the pulley bolt holes, and puty a pry bar between them, so I can hold the balancer still with one hand, and break the bolt loose with a breaker bar and the other. Or you could have a friend help, or use a bar long enough to contact the floor and hold things firm. Just remember to keep the bar close to the balancer..like laying flat accross it, or you'll just bend the bolts or worse..break them off in the holes...
