Valves shouldalways be refitted to their original seats (see Chapter 1 for engine specifications).(5) Ensure that valve head depth is correct relative to the cylinder head face (see Figure 5-7). Place astraight edge across the face of the cylinder head. Use a feeler gage to measure the valve head depth.If the depth exceeds the maximum limit, install a valve seat insert (see paragraphs 1-42 and 1-43).Figure 5-7. Gaging Valve Head Depth.e. Disassembly of Rocker Shaft Assembly (See Appendix E Figure 57).(1) Remove retaining rings (3) from each end of the rocker shaft (5).(2) Remove rocker levers (15), springs (12), and support brackets (11) from rocker shaft (5).(3) Remove connector (22) from rocker shaft (5).f.
