In the comprehensive guide “11 Steps for Flushing a Hydraulic System” by Tom Odden, as featured on ForConstructionPros, the intricacies of proper hydraulic system flushing are unveiled. The article emphasizes the importance of meticulous cleaning, especially when transitioning from one fluid type to another.

Recognizing the critical need for a thorough flushing process, our expertise is shared, providing insights into the essential steps for maintaining hydraulic system integrity. As a starting point, it is crucial to drain the system while the fluid is at operating temperature. Attention to detail is key, addressing components such as reservoirs, lines, cylinders, accumulators, and filter housings. We recommend replacing filters and ensuring the reservoir is free of sludge and deposits.

The flushing process involves using a lower viscosity fluid similar to the intended fluid, with careful attention to achieving the target cleanliness levels. We underscore the significance of promptly draining the flushing fluid, replacing filters, and inspecting/cleaning the reservoir. Subsequent steps include filling the system with the intended fluid, priming the pump, operating actuators, and monitoring fluid levels.

Emphasizing the importance of observing system sounds for indications of cavitation and regularly sampling and testing the fluid, we prioritize the reliability and efficiency of hydraulic systems.
