Ok guys, all I want to know is wich Hercules engine model was in the OC 9 serie B. I know it is a diesel, 4 cylinder with 212 cubic inch. The Hercules engine tag is missing on this block. This is my first experience with Hercules, so all I need is an engine model so I can track parts for it.
You have a very late OC-9!. It is a Herculess DD series. What parts are you looking for?
