Examine the vibration plot to see if the displacement went down.
Remove the set screw and move it to the next hole.
Do this until you find a balance hole that makes the displacement go down to the lowest point.
Increase the weight of the screw until you reach the lowest possible reading on the displacement plot.
Do this step again with additional set screws until the displacement plots are within specification.
Once the plot is within specification, do this step for each set screw:
- Mark the hole that has a set screw.
- Remove the set screw.
- Apply thread lock compound to the screw.
- Install the screw into its marked location.
