[QUOTE="KC743, post: 71599, member: 10199"] Thank you for the reply Tazza! It is the 6 bolts holding the flywheel to the crankshaft. The alignment pin sheered off as well as it was just a little dowel pin. I agree that they had to be over tightened and stressed as I did not feel any play when installing the u-joints and aligning onto pump shaft during engine installation. I now have 6 bolts stuck in the crankshaft and have broke off 2 extractors after drilling out the bolts and counting threads to ensure I did not go all the way through the bolt. I matched the size of bolt to extractor and bit. I am going to take the engine to a welder / fabricator to get bolts out. I also agree Tazza that the pump can be ruled out. Hope all goes well and thank you guys for your input, I really like this site and it's members! I have pictures but am unable to copy the HTML from photo bucket to this message box. :) [/QUOTE]
