Question 1 of 27070

Increased internal leakage, in addition to poor hydraulic system response, and inadequate lubrication, is the result of __________.

🔍 Key Concepts

• Hydraulic oil viscosity and how it affects leakage and response time • Differences between internal leakage (inside components) and external leaks • How clearances and wear in hydraulic components affect lubrication and pressure

💭 Think About

• Which of these choices would affect every part of the hydraulic system at once, not just a single component? • What condition would cause oil to bypass clearances more easily, leading to both more internal leakage and slower system response? • Which option would reduce the oil film strength needed for proper lubrication inside pumps, valves, and actuators?

✅ Before You Answer

• Identify which choice changes the fluid property rather than just one mechanical part • Ask whether the option would increase oil flow through internal clearances, causing pressure loss and sluggish operation • Consider which condition would make it harder to maintain a protective lubricating film between moving metal surfaces
