Just looked at it again - I am wrong on the 11:38 part. Pressing to put the keepers in does not press the shaft to the bearing. But I know the shaft has to be sufficiently tight to the bearing to prevent if from spinning in the bearing. Possible it all gets tightened (pressed) when the halves are assembled and the front an back bearings are both "squeezeed" to the shaft when the housing is torqued.
