Chapter Overview
This chapter explains how the parts of the camshaft
and valve train work together to open and close the
intake and exhaust valves of the engine. There is also a
focus on installing the camshaft, the cylinder head and
valve train, and the timing components.

Chapter Objectives
Describe the purpose, operation, and location
of the camshaft.
Identify the parts of the valve train and the
purpose of each.
Inspect the camshaft, valve train and timing
components.
Describe the four types of camshaft drives.
Explain the factors involved in
camshaft/crankshaft timing.
Explain how to adjust valve lash.
