Not all hydraulic systems fail the same way. Two machines can show identical symptoms—slow travel, weak swing, noisy pump—but the root cause changes dramatically by brand . Why? Different pump architectures Different valve strategies Different tolerances Different contamination sensitivity This guide breaks down hydraulic failure decision trees by brand , so you stop applying the wrong fix to the wrong machine.
