🔍 Key Concepts

• engine-driven lube oil pump operation during startup • purpose of pre-lubrication in diesel engines • what must be done to ensure proper oil flow and temperature control before the first crank

💭 Think About

• Think about what happens to bearings and moving parts if you crank an engine with no oil pressure. Which option directly protects those parts before the engine turns? • Which choice is something you would typically do once the engine is already circulating oil versus something you must do before any rotation? • Consider which action ensures that the lube oil system is at the correct pressure and ready to supply oil the moment the engine starts turning.

✅ Before You Answer

• Identify which option will create oil pressure and flow before the engine turns on its own. • Decide which actions are normal system configuration steps versus a specific pre-start procedure. • Verify which step directly prevents metal-to-metal contact at first rotation of the crankshaft.
