My stock (appears stock) HB sheared into 2 pieces. I ordered a Fluid dampened replacement, from C.A.T. Power Engine Parts (C.A.T. Power Engine Parts) via a local speed shop. I specified 94 mustang gt 5.0 HO. I get it torn apart, cant get the bolt out of the crank, so I use triple A to get it towed back to the base auto hobby shop. Long story short, I get the old one off, part arrives in the mail, and the new one wont go on because it is hitting the water pump. So Im thinking I bent my crank when my balancer broke. It cant be more than a 1/4"- 1/2" od too big, but by now I'm stuck with it, and paying daily lift fees. I just came across the shipping invoice after the fact, and it says 81-93 SFI Fluid Damper, and the same for the pulleys, which the alternator pulley is to thick to bolt on safely. Is this common, I read on (ATI - Custom Ford Water Pump) that you may have to machine the water pump, or buy a $400 replacement. Any thoughts (besides read the shipping invoice first) if it is the distributors fault, will they swap out a performance part thats already been installed? If not, can I make this part work? Sitting dead in the water here.
