Tips for visually identifying loose components on a machine:

  • Make sure that the machine has reached normal operating temperature,  because loose components may not appear until this temperature has been reached.
  • Squirt water or soapy water on components. This may create small bubbles and allow identification of the loose component.
  • Use a strobe light
  • Utilize technologies such as vibration analysis and phase analysis.
