okay so heres the deal. I have a c10 with a 700r4 and origionally a 6.2 diesel. I put a 350 gasser in place of the diesel. When I started it up this afternoon the first time it turned over nice and fast... the second time I cranked the engine the starter dragged like the battery was discharged and the third time I cranked the engine the starter made a loud grinding noise. I looked at the starter and the nose of it had broken completely off and was lodged in between the flexplate. I pulled the starter off and the flexplate teeth don't appear to be damaged. This was a slightly used 350 that I put in this truck and the starter motor had been on it for a while. I never removed the starter I just dropped it with the engine and everything in the truck. Is it possible that I needed to shim the starter and this was the problem even though it had started the engine probably a hundred times before? Is it possible that the flexplate could be warped and causeing this? I would hate to put a new starter on there just to have the same thing happen again? Does anyone know the procedure for checking to see how much you need to shim the starter? I was really looking forward to driving this truck... I hope its not anything too crazy going on.... Thanks in advance for any ideas.
