🔍 Key Concepts

• Diesel engine lube oil system flow path (from pump to engine parts) • Which parts are most critical to crankshaft support and engine survival on startup • Difference between pressure-lubricated bearings and parts cooled or splashed by oil

💭 Think About

• If oil pressure is lost or slow to reach a component, which of these parts would cause the fastest catastrophic failure of the engine? • Think about how lube oil is typically routed: from the pump, through filters and coolers, then to which major structural bearings before going to smaller components? • Which listed component depends entirely on forced lubrication under load, rather than mainly for cooling or secondary motion?

✅ Before You Answer

• Identify which choice is directly connected to the crankshaft support structure • Consider which components often receive oil after it has already passed through other bearings • Confirm which of the options is most critical for maintaining alignment and rotation of the crankshaft at all times
