What are the Main Reduction Gear LO sump capacities for port and starboard?

• A. 1,702 / 1,747 gallons
• B. 1,752 / 1,747 gallons
• C. 1,753 / 1,746 gallons
• D. 1,752 / 1,745 gallons

Answer: (B)

Sump capacity is the volume of lubricating oil that the Main Reduction Gear LO sump can hold on each side, and knowing the exact per-side capacities is essential for accurate oil fill levels and proper lubrication during operation.

For the Main Reduction Gear LO sump, the correct values are 1,752 gallons on the port side and 1,747 gallons on the starboard side. This pairing matches the documented specification and reflects the slight difference between the two sides, which affects how you gauge oil quantity during maintenance checks.

Other options deviate from these documented per-side capacities, which would lead to incorrect oil level readings and potential overfill or underfill if used.
