🔍 Key Concepts

• Effect of flow restriction in a lubrication system • Relationship between oil flow, pressure, and temperature • Typical symptoms of poor lubrication at bearings and moving parts

💭 Think About

• Think about what happens to oil flow if the strainer is partially clogged and offers more resistance to flow. • Which of the answer choices is most directly caused by reduced oil flow to bearings, not by oil quality or temperature changes alone? • Which outcome would you expect to see on your engine gauges (pressure and temperature) if the pump is trying to push oil through a blocked strainer?

✅ Before You Answer

• Identify which choices describe a flow/pressure problem versus a quality/consumption problem. • Consider how a dirty strainer affects pump suction and discharge pressure. • Ask yourself which condition is a common alarm on engines when lube oil flow is restricted: pressure, temperature, or consumption.
