turn the rotor over several times.
If you have uncoupled the machine from the driven machine and secured the rotor with a
rotor shipping brace, then remove this before turning the rotor over or starting the machine
up.
Make sure that the resting position of the roller bearings after the rotor has been turned
over is different from what it previously had been. Use the fitted key or the coupling halves
as reference markers.
