It is anywhere from a slip fit to a light pressed fit and is also glued during assembly. On most of mine a bead of a clear epoxy like adhesive is usually visible around the tube on the top or bottom.
If you remove the bearings and use a butane micro torch to apply heat on the inside of the bearing tube you can usually soften the adhesive and twist the stator off. The problem on these motors is usually that of getting a good grip on the tube to do that. I would probably put the mount on the tube and attach the mount to a metal plate with a hole in it that allows the heating. Clamp the plate in a vise and use a gloved hand on the stator. When it will rotate slightly slide it off.
If you get a chance, show us your mount. it will be interesting.
