havn't posted in awhile, so i thought i would write a little story of my last repair. i have a 57 ford conv with a 312 mtr,. was going for a last year ride so pulling out of the garage i heard a strange noise, lifted the hood an a rattle noise comes from the front of the mtr, turns out its the harmonic balancer, it had come apart, there are 2 parts to it, a ring with a rubber insulator on the main part of the balancer, and someone mentioned that it could be repaired, which i did do, any way, what it takes to replace it, this i found to be the easy way, 1st take off hood, 2nd, pull grill, 3rd pull radiator, then u need a pulley puller which i made up, but i did it the hard way, pulled rad first, then grill, then hood, why the long story, any way then to find a old or new harmonic balancer was hard until i get the new one, which i put in stock, i didn't have any thing else to do thats why the story in case someone else runs into the same problem
