🔍 Key Concepts

• Pressure lubrication systems in medium and high-speed diesel engines • The function and importance of main bearings vs. crankpin journals vs. wrist pins • What components must be protected first to avoid catastrophic crankshaft damage

💭 Think About

• Think about which engine parts directly support the crankshaft and the whole rotating assembly under constant heavy load. • Ask yourself: if oil pressure is lost, which component failing first would most likely destroy the engine immediately? • Consider the usual path of oil flow from the pump: which major support surfaces are it most critical to supply before feeding oil to more remote parts?

✅ Before You Answer

• Identify which component is the primary support for the crankshaft in the engine block. • Confirm which parts are lubricated by pressurized oil galleries first, versus those that may receive oil after it has already passed through other bearings. • Make sure you distinguish between supporting bearings and connecting rod-related bearings (such as crankpins and wrist pins).
