SVCN 7 INSTALLATION, OPERATION, & MAINTENANCE
11. Set the bar sag amount(s) determined in steps 5 through 9 above into the indicators as a plus
amount (example: an indicated -0.003 would be set in as a +0.003) while in the upright (12
o'clock) position.
NOTE
Use of a shaft alignment graph, such as Flowserve Shaft
Alignment Calculator (see Figure 2-11) aids and simplifies
the alignment process. It graphically shows the position of
the shaft centerlines in both the vertical and horizontal
planes, the shims to be added or removed, and/or horizontal
corrections to be made for accurate alignment. Further
information may be obtained through the Flowserve Service
Department.
