Soon to the shipyard to turn wrenches! We may get a chance to pop out an aft shaft tube bearing with a manual hydraulic jack pulling on an aluminum place we placed at the other end of the bearing. To install, they put it in dry ice to shrink it, then put it into the tube. Once it expands it has a great seal. Normally they get glued in (different type of bearing and material) and we have to cut them and collapse them to get them out.
