Water contamination, the scourge of hydraulic oil, increases wear, promotes cavitation, depletes additives, degrades lubricant base-stock and enables microorganism growth. This paper explores the various ways in which water degrades hydraulic system reliability and suggests a program of oil analysis that will reveal to the diagnostician the nature and cause of the water ingress. This paper emphasizes the art of simultaneously interpreting multiple oil and wear debris analysis parameters to gain an understanding about the nature and severity of an incident of water contamination.
