Filtration system components do what to hydraulic fluid?

• A. Parts That Filter Contaminants from Hydraulic Fluid.
• B. Parts That Lubricate Steering Components.
• C. Parts That Regulate Suspension Height.
• D. Parts That Control Fuel Flow.

Answer: (A)

Filtration system components remove contaminants from hydraulic fluid to keep the system clean and prevent damage to pumps, valves, and actuators. As fluid moves, it can pick up dirt, metal particles, and moisture, and the filters trap these hazards so the fluid can keep its proper flow and viscosity. This function is separate from lubrication, suspension control, or fuel regulation—those tasks belong to other parts of the system. Keeping the fluid clean through filtration helps extend component life and maintain reliable operation.
