Which code indicates a loss of main reduction gear lubrication oil pressure?

• A. NVRG
• B. HBRG
• C. LLOPR
• D. LUSU

Answer: (C)

Understanding fault codes helps you respond quickly to specific equipment conditions. LLOPR is the code for Loss of Main Reduction Gear Lubrication Oil Pressure. This exactly describes the scenario where the lubrication pressure in the main reduction gear drops, which is dangerous because the gear relies on circulating oil to lubricate bearings and remove heat. Without adequate pressure, metal-to-metal contact can cause rapid wear or seizure, so recognizing this exact code prompts the correct, immediate actions. The other codes do not describe this condition, so they don’t indicate a loss of lubrication oil pressure in the main reduction gear. When LLOPR appears, follow the established procedures to verify oil level, check the lubrication system including pump, lines, and filters, look for leaks, and take action per your duty plan to protect the gear (such as reducing load or securing the gear as required).
