depends on where your standing. funny you ask this, Dad and I have debated this the last 2 days in order to find out how to hook it up to a PTO pump.
if your standing at the rear of the truck, looking at the flange out the rear it turns counterclockwise. if your standing at the front of the truck looking at the flange out the front it turns clockwise.
If your standing, persay, on top of the cab, the rear drive shaft, looking at the rear axle turns clockwise. if your standing on top of the cab, the front drive shaft, looking at teh front axle turns counterclockwise.
now to really confuse you, both output shafts on the transfer case turn the same direction, only one is clockwise and one is counterclockwise. it all depends on where your standing and looking at it from.
heres a vid of what i'm using my deuce for, should give you an idea of our debate....
