🔍 Key Concepts

• Main engine reduction gear set purpose and how it is lubricated • What happens to gears and bearings if oil level, oil flow, or temperature are not correct • Typical parameters engineers routinely log for gear operation

💭 Think About

• Ask yourself: If you want to protect a reduction gear, what conditions must you watch to be sure the bearings and gear teeth are not starved of oil or overheating? • Which of the listed items, if ignored, could quickly lead to serious gear damage? One, some, or all? • Think about what an engineer normally checks on regular engine room rounds around the main reduction gear.

✅ Before You Answer

• Verify which items directly relate to lubrication and cooling of the gear and bearings. • Consider whether focusing on only one indication (like just level or just temperature) would be enough for safe operation. • Ask: On a real ship, what readings/indications would be listed on the engineering log sheet for the main reduction gear?
