Both engines crankshafts turn counterclockwise when standing in front looking at the fans. I think I only muddied the waters adding the talk about what the manuals say. Detroit Diesel always refers to rotation direction when looking at the engine from the flywheel end. The military refers to rotation direction from the fan end in the manuals. So the twin set up has both crankshafts turning the same direction, counterclockwise when observing from the fan end of the motors. The camshafts turn opposite direction because you are feeding the engines from opposing sides.
My Sexton uses the 9 cyl. radial.
