My son bought a salvaged 1994 V6 mustang for $800 2 years ago. Had/has a few problems but runs well and was a great car for him in high school and when he is home from college. He is home this weekend, and it broke down on him. He drug it home and handed me the crank shaft pulley! It would appear the bolt in the middle that holds it on came out. Easy enough to reinstall. Except...the collar that fits over the end of the crank is broken off flush with the oil seal. Does anyone have any ideas about getting the broken end of the pulley off of the end of the crank shaft?
