 Summary:
 The methodology of analyzing vibration-generated deflection shapes of a machine support is presented in this paper, followed by an example of application on a pump producing excessive vibrations. Methodological approach testing-analysisdiagnosis-repair has been applied in order to determine and eliminate the causes of excessive vibrations. The location, the type and the degree of defect were determined, as well as the appropriate procedure of repair. Following the repair, the tests have been repeated in order to verify the efficiency of the applied remediation techniques.
