Technician A says that the first parts of the engine to be lubricated are the crankshaft bearings. Technician B says that the rocker arms are the first engine parts to be lubricated. Who is correct?

A. Technician A
B. Technician B
C. Both Technician A and Technician B
D. Neither Technician A nor Technician B

Answer :

Final answer:

Technician A is correct; the crankshaft bearings are the first parts to be lubricated in an engine. While rockers also need lubrication, they are not the first to receive oil. Understanding this relationship is crucial for engine maintenance.


Explanation:

Lubrication in Engines

When it comes to engine lubrication, both Technicians A and B have opinions on which components are lubricated first. However, in most engines, the first parts to receive oil are indeed the crankshaft bearings, as they require lubrication immediately to reduce friction from the connecting rods and handle the forces exerted during operation. Therefore, Technician A is correct.

Key Points

  • The crankshaft bearings are crucial for supporting the crankshaft and are prioritized in the lubrication process.
  • Rocker arms, while also important components that require lubrication, typically receive oil after the crankshaft bearings, as they are slightly lower in the lubrication hierarchy.

Understanding the order of lubrication can help in diagnosing potential engine issues and ensuring engine longevity.
