Section 2 - Cylinder Head - Group 02 Cylinder Head - General Information M11 Page 2-7 Cylinder Head - General Information The Cylinder Head Group consists of the cylinder head, valves, valve guides, valve springs, valve seat inserts, crossheads, and the injector sleeves. The exhaust valves are manufactured from a material that is capable of operating at a higher temperature than the intake valves. The exhaust valves can be installed in the intake valve location. Do not install the intake valves in the exhaust valve location. The valve seat inserts are the same for both the exhaust and intake valves. The intake spring is the same as the exhaust spring. The springs are interchange- able.
Mark, label or tag the cylinder head parts such as crossheads, valves, and valve springs with the cylinder number and location from which they were removed. This practice will be a valuable aid in diagnosing any cylinder head or part failures. Install the acceptable parts in their original locations.
