The design of the components in this hydraulic system permits efficient operation with a small amount of contamination. An increase in this amount of contamination can cause problems in the hydraulic system. The following list includes some of these problems: • Cylinder rod seals that leak • Control valve spools that do not return to neutral • Movement of control valve spools is difficult • Hydraulic oil that becomes too hot • Pump gears, housing, and other parts that wear rapidly • Relief valves or check valves held open by dirt • Quick failure of components that have been repaired • Slow cycle times are slow. The machine does not have enough power. If your machine has any of these problems, check the hydraulic oil for contamination Identify the Tier Level of your Equipment (Read our Article on Tier Level )
