🔍 Key Concepts

• Hydraulic system contamination effects on pumps, motors, and valves • Difference between gradual wear and damage vs. immediate catastrophic failure • How solid particles in oil typically affect close-clearance moving parts

💭 Think About

• Which component in a hydraulic system has very close tolerances and would be most sensitive to abrasive dirt in the oil? • Would dirt in the sump usually cause a slow degradation over time, or a sudden, immediate failure of everything at once? • Think about real-world behavior: does contamination usually change lifting capacity directly, or damage internal components that then affect performance over time?

✅ Before You Answer

• Eliminate options that describe immediate and dramatic failures that are unlikely from normal dirt contamination. • Focus on choices that involve internal moving parts with close clearances (pump/motor) rather than external coverings or sheathing. • Ask whether the effect described would be a gradual wear problem or a sudden one-time event; contamination is usually linked to gradual wear.

Question 1 of 20

If dirt is allowed to contaminate the sump of a hydraulic deck crane, which of the following problems will occur?

The internal parts of the pump and hydraulic motor will wear excessively.

The sheathing on the hydraulic lines will fracture.

All the seals in the hydraulic lines will immediately blow out.

The lifting capacity of the crane will be immediately reduced by 70%.
