Which of the following conditions may exist if you detect an excessive amount of metal particles on a main engine lube oil strainer magnet?

🔍 Key Concepts

• Location and purpose of lube oil strainers and magnets in the main engine system • Which components produce fine ferrous (iron/steel) particles when they begin to wear abnormally • Difference between gear tooth damage and bearing/journal wear in terms of metal particle size and pattern

💭 Think About

• Think about which part of the engine is continuously supplied with lubricating oil and would shed small, magnet-attracting particles if it began to fail. • Consider how gear damage usually shows up (noise, vibration, broken tooth fragments) versus how bearing or journal wear shows up (gradual increase in fine metal in the oil). • Ask yourself which component listed would most directly circulate its wear particles into the main engine lube oil system, where the strainer magnet can catch them.

✅ Before You Answer

• Which of the listed components is lubricated by and drains back into the main lube oil system (not a separate or limited circuit)? • Would damage to this component be more likely to produce fine, evenly distributed metallic particles rather than large chips or chunks? • Verify that the component you select is made of ferrous material (steel/iron) that would be caught by a magnet in the lube oil strainer.
