As shown in Figure 8-29 the cold alignment line is drawn
from the first bearing location of the stationary machine with a
slope of 1.4 mils per inch. This line represents the current position
of the centerline of the stationary machine shaft.
All indicator readings will be measured from this newly con-
structed cold alignment line. This will assure, once the machine is
