🔍 Key Concepts

• Jacking (turning) gear purpose before turbine start-up • Relationship between slow rotation and bearing lubrication • What is actually happening in the bearings and reduction gears just before rolling the turbine on steam

💭 Think About

• When you engage the jacking gear before starting, what are you trying to make sure happens inside the bearings and gear teeth? • Which choices describe something that would logically be done before start-up, and which sound more like things done after shutdown or only as a side benefit? • Think about what needs to be in place to protect the rotor and gears the very first time they begin to turn under their own power.

✅ Before You Answer

• Identify which option directly involves protecting bearings/gears from metal-to-metal contact at initial rotation. • Eliminate any options that mainly involve cooling after shutdown rather than conditions just before starting. • Ask: which choice matches the standard textbook description of why you run the turning/jacking gear with the lube oil pumps running before admitting steam?
