They turn the same direction, but to make sure just inspect the fan. The engine direction of rotation is such that the fan turns to draw air through the radiator and then blows back on the engine (the air flow from the fan is in the same direction air flows with the car running, from front to back). The pitch of the blades should be such that when it is driven the blades push air from front to back.
I am more than certain the direction of rotation is clock wise, and I just checked my 350SD, and it is clock wise.
So, it sounds like you are back in business. Did you get the old chain back up out of the "chain box" at the front of the engine without taking the injection pump stuff and the crankshaft gear off? Good luck, Jim
