But it does bring up a thought. Since the outer rings are the same spline pitch diameter, but the teeth are sized to make up the 2 tooth diff in the same space, could the upper and lower rings be interchanged to reverse the output rings direction? Something in my ancient wet ram says one of the two directions would be lower friction. But I'll be switched if I can explain why it should be so. Thanks for your views and or experiences.
