AG Mechanics CDE Practice Exam

In an overhead valve configuration, where are the rocker arms installed?

1. In the cylinder head

2. On the crankshaft

3. In the oil pan

4. On the flywheel

The correct answer is: In the cylinder head

In an overhead valve configuration, the rocker arms are installed in the cylinder head. This allows them to actuate the valves located in the head, which control the flow of air and fuel into the combustion chambers. Option B, on the crankshaft, is incorrect because the rocker arms are not responsible for moving the crankshaft. Similarly, option C, in the oil pan, is incorrect as the rocker arms are not typically located in the oil pan. Option D, on the flywheel, is incorrect as the flywheel is a component of the engine that maintains the rotational energy and has no involvement with the valve system.
