The most common contributors include contamination, incorrect fluid selection, and mechanical issues within the reservoir or circulation path. This results in delayed actuator response, spongy feel in controls, and a significant drop in system pressure.
Common Causes of Oil Foaming and How to Identify Them
Diagnosis and Troubleshooting Steps The Simple Bubble Test A reliable method to assess the severity of the issue is the bubble test. Perhaps the most common offender is the introduction of foreign fluids, such as diesel fuel or hydraulic fluid from a different manufacturer.
Contamination and Fluid Degradation Contamination is the leading cause of abnormal foaming. Simply looking at the foam is not enough; one must determine the origin and the speed of generation.

Additionally, excessive agitation from high-pressure injection or a failing pump impeller can force air into the fluid faster than it can escape. Pour the oil into a clean, transparent glass and let it sit undisturbed.
