You are correct and that has been addressed in previous posts. The dial indicator will not measure sleeve gear misalignment with the case. Please read the following posts. If some sort of device was mounted to the sleeve gear and a machined surface on the case was gauged that was perpendicular with the C/L of the axis of sleeve gear rotation between the bearings, then we could measure that misalignment.I agree, the shaft setup is fine as you are not measuring it against anything but itself. The sleeve gear on the other hand is being measured against it's concentricity and squareness in the case. Mounting the base as you have will not tell you that.
"However, the bearing could be misaligned in the case and still show .000: runout."
That is what I am thinking. When I get my sleeve gear and bearing back from the machinist I am going to very carefully install the sleeve and inner case bearings. I think the press will allow me to assure that both bearings are seated fully/squarely and the properly fitting sleeve gear will probably allow a slight bit of self alignment since the bearing is a single row ball bearing. With the .002" interference fit it caused a very slight amount of drag in the bearing itself. Not enough to be concerned with seizure, but still not 100% to spec and it certainly wouldn't allow any alignment tolerance IMO.
