(1) Single valve springs Length under test force ... 39.0 mm (1.54 inch) Test force ... 136 to 154 N (31 to 35 lb) (2) Valve spring seat insert for the valve spring (3) Valve guides Inside diameter ... 9.000 to 9.022 mm (0.3542 to 0.3552 inch) Outside diameter of inlet valve guide ... 13.034 to 13.047 mm (0.5131 to 0.5137 inch) Outside diameter of exhaust valve guide ... 14.034 to 14.047 mm (0.5525 to 0.5530 inch) Bore diameter in the cylinder head for the inlet valve guide ... 13.000 to 13.027 mm (0.5118 to 0.5128 inch) Bore diameter in the cylinder head for the exhaust valve guide ... 14.000 to 14.027 mm (0.5512 to 0.5522 inch) Interference fit of valve guide in the cylinder head ... 0.007 to 0.047 mm (0.0003 to 0.0019 inch) Overall length of inlet and exhaust valve guides ... 51.25 mm (2.018 inch) Projection of valve guide above valve spring recess (2) ... 14.85 to 15.15 mm (0.585 to 0.596 inch)Note: When new valve guides are installed, new valves and new valve seat inserts must be installed. The valve guides and the valve seat inserts are supplied as partially finished parts. The unfinished valve guides and unfinished valve seat inserts are installed in the cylinder head. Then, the guides and inserts are cut and reamed in one operation with special tooling. This procedure ensures the concentricity of the valve seat to the valve guide in order to create a seal that is tight. Refer to the Disassembly and Assembly Manual for removal and installation procedures.
