🔍 Key Concepts

• Rocker arm assembly location in a 4‑stroke diesel cylinder head • Relationship between camshaft → push rod → rocker arm → valve stem • Visual differences between a rocker cover and the rocker arm mechanism underneath

💭 Think About

• Trace the motion path: starting at the camshaft in the crankcase, follow the push rod up to see which labeled component it actually moves at the top of the cylinder head. • Look for the part that pivots over the valve springs and simultaneously presses down on the valve stems—identify which labels point to this lever assembly on each bank. • Compare the parts under the valve cover on both sides; which two labels are pointing to very similar pivoting lever assemblies rather than to covers, springs, or injectors?

✅ Before You Answer

• Verify that each chosen label points to a pivoting lever over the valve(s), not to a spring, valve stem, or injector body. • Confirm that the same type of component is identified on both the left and right cylinder banks—the rocker arm assemblies will look nearly identical on each side. • Double‑check that you are not selecting the rocker cover (the top housing) but the internal mechanism that actually opens the valves.
