Ok I have a machine with an A06B-6055-H106 spindle drive that seems bad. We have another parts machine that has a A06B-6055-H108 drive. Visually and connectors they seem identical. Is there a meaningful difference between these 2 drives or should I be ok just swapping them? The control board on the front runs the same part number so if need be Ill just try swapping that but I figured i would swap everything if possible.
