BRACKET WITH ADJUSTING SCREW
Figure 3-4 Positioning of bracket plates
Bracket plates are placed against the foundation edge and tied down with expansion bolts, see
Figure 3-5 Mounting of the bracket plate. Move the machine by using the adjusting screws until
the shaft centerline and the driven machine centerline are aligned roughly and the desired
distance between the coupling halves is reached. Leave all adjusting screws only lightly
tightened.

Figure 3-5 Mounting of the bracket plate
NOTE: Figure 3-5 Mounting of the bracket plate shows bracket plate mounted to concrete
foundation, place similar bracket plate on steel foundation.
The sleeve bearing in the D-end is equipped with a pointer for showing running center, which is
marked with a groove on the shaft. There are also grooves on the shaft for rotor mechanical end
float limits. The position is correct when the tip of the pointer is in line with the machined
running center groove on the shaft, see Figure 3-6 Markings on shaft and running center
pointer. Notice that the running center is not necessarily the same as the magnetic center as the
fan may pull the rotor from the magnetic center.
