🔍 Key Concepts

• Purpose of reduction gear bearing lubrication (what does the oil actually do there?) • Difference between pressure readings and temperature readings in a lube oil system • Where in a lube oil system you can directly confirm that oil is actually reaching a specific component

💭 Think About

• Ask yourself: which measurement would change FIRST if oil flow to the bearing stopped or was restricted? • Think about which reading tells you about the specific bearing’s supply, not just general system condition. • Consider normal troubleshooting: if you suspect no oil to a bearing, what is the very first gauge you look at?

✅ Before You Answer

• Identify which option gives information specific to the bearing’s supply, not just overall system health. • Decide which parameter responds quickly and directly to loss of flow: pressure vs. temperature. • Eliminate choices that only show after-the-fact effects (like heat buildup) instead of confirming supply in real time.
