🔍 Key Concepts

• Function of main bearings in supporting the crankshaft and maintaining clearances • Relationship between bearing wear, clearances, and oil pressure/temperature • Difference between problems caused by compression components (pistons, rings, liners) vs. rotating components (bearings, crankshaft)

💭 Think About

• Think about what happens to the clearance between the crankshaft and the main bearings when they are worn. Does it get larger or smaller, and how does that affect oil flow? • Ask yourself: which options are more directly related to cylinder condition (pistons, rings, liners, valves) rather than the crankshaft bearings? • Consider how an increase in leakage path for lube oil through the bearing would affect both oil pressure and temperature.

✅ Before You Answer

• Identify which choices deal with cylinder compression versus lubrication system behavior • Recall that worn bearings = increased clearance = easier oil flow; think how that impacts system pressure • Eliminate any options that describe effects mainly caused by piston rings, cylinder liners, or valves, not by main bearings
