Figure 3-8 Definition of misalignment
The alignment of the machine is performed according to these guidelines.
1. The machine should stand on its jacking screws
2. Rotate the rotor and check the axial end float, see Chapter 3.6.3 Rough adjustment
NOTE: Sleeve bearings must be filled with oil before turning.
3. Mount the alignment equipment. If gauges are used, it is practical to adjust the dial gauge
in such way that approximately half of the scale is available in either direction. Check the
rigidity of the gauge brackets in order to eliminate the possibility of sag, see Figure 3-9
