You would do well to spend a little time on Jake Raby's web site (Google flat6innovations.com) reading about the IMS in general, he answers most questions clearly and concisely. Why can some earlier motors be retrofitted vs. later ones; The earlier motors' IMS bearing was "pressed in" fit and can be extracted, later motors IMS bearing were fitted inside a concave section and only could be removed by disassembling the motor and splitting the case. That's my understanding at least.
