🔍 Key Concepts

• Purpose of jacking a main engine or turbine (slow turning to check condition or for maintenance) • How compression inside cylinders affects the load on the jacking gear • Function of different valves and lines: fuel line, expansion tank, cylinder test valves, sea valve

💭 Think About

• When you slowly turn a large engine with a jacking gear, what creates the most resistance to turning? • Which option, if opened, would relieve pressure from inside the cylinders during rotation without introducing other risks? • Which of these devices is specifically associated with checking or blowing down engine cylinders rather than fuel, cooling, or seawater systems?

✅ Before You Answer

• Identify which choice is directly connected to the engine cylinders and their internal pressure, not to fuel or seawater systems • Ask: does opening this component safely relieve compression during slow turning, making jacking easier? • Confirm that the selected device is normally used during engine testing, starting checks, or blow‑through rather than during normal fuel or seawater operations
