Perform alignment checks under these circumstances

Perform periodic alignment checks following plant operating procedures

Enter the Total Indicated Reading (T.I.R.) at operating temperature

Enter the tolerance of the indicator

4.3.3 Alignment measurement guidelines

Rotate the pump coupling half and the driver coupling half together so that the indicator rods have contact with the same points on the driver coupling half

Move or shim only the driver to make adjustments

Are the hold-down bolts for the driver tight when taking indicator measurements?
