🔍 Key Concepts

• How an oil bath air cleaner works to trap dust and particles • Correct oil level needed for air to pass over or through the oil without flooding the intake • The role of the wire-mesh element in relation to the oil surface

💭 Think About

• Mentally picture the air path: from outside the cleaner, past the oil, through the mesh, into the engine. At what oil level would this work best? • Think about what would happen to engine breathing if the mesh were totally submerged in oil or if there were almost no oil in the cleaner. • Which option describes an oil level that allows air to pick up oil mist on its way through the mesh, rather than blocking airflow or leaving the mesh dry?

✅ Before You Answer

• Eliminate any option that would block normal airflow or risk oil being sucked directly into the intake. • Eliminate any option that would leave the mesh mostly dry during normal operation, since the oil film is key to trapping dust. • Focus on the description that keeps a controlled oil surface at a specific level relative to a fixed part (tube/hole) inside the cleaner.
