Q

After starting the main lube oil pump in a gravity-type lube oil system, you should verify that the gravity tanks are full by __________.

🔍 Key Concepts

• Gravity-type lube oil system operation and purpose of gravity tanks • How an overflow/return path indicates a tank is full • Difference between checking quantity in a sump vs. a tank mounted at a higher level

💭 Think About

• Ask yourself: when a gravity tank is full and supplied by a pump, what visual indication would you expect to see without having to open or sound the tank? • Which option directly relates to the design feature that prevents overfilling a gravity tank? • Which checks are about verifying lubrication at the bearings vs. verifying that the tanks themselves are full?

✅ Before You Answer

• Identify which choice uses an indirect, continuous visual indication of tank level rather than a one-time manual measurement. • Separate options that check system operation (lubrication at bearings or oil in sump) from options that check tank level. • Ask: in normal engine room practice, which method is safest and most convenient while the system is running at sea?
