Yes, the plastic gear housing is just not up to the task of holding those metal gears all in place for the long term. The gear transplant will probably be required on my SU 100 one day. I believe in running them unitl failure though, and so far the SU 100 has stayed together. I still have the metal tracks on the shelf though, as I have been afraid to tax the stock gearbox with the addition of the metal tracks. Seems like once you go to metal tracks you better be prepared for things to start going wrong.
