Question 1 of 27070

To assure the main propulsion turbine bearings are receiving the proper lube oil supply, you should check the __________.

🔍 Key Concepts

• Purpose of lube oil to turbine bearings (what problem are you trying to detect?) • Difference between flow indication at the bearing versus upstream or downstream indicators • What measurements actually prove that oil is physically reaching the bearing surfaces

💭 Think About

• Ask yourself: which item tells you directly that oil is moving through the bearing itself, not just present somewhere in the system? • Which check would change immediately if the supply to that specific bearing were lost or blocked? • Which option confirms condition at the point of use (the bearing) rather than general system condition?

✅ Before You Answer

• Identify which option is located right at or just before the bearing rather than in a tank or cooler • Decide which reading would respond quickly to a loss of supply to the bearing • Eliminate options that only show oil quality, temperature, or tank condition, not actual flow to the bearing
