1. Put the valve guide in position. Carefully tap the valve guide in order to start the installation. Use Tooling (A) and Tooling (B) to seat the valve guide in the cylinder head.

   Note: After installing the unfinished valve guides and valve seat inserts, you must ream the valve guides and valve seat inserts to the finished diameter. The valve guides and valve seat inserts are cut and reamed in one operation. This operation is performed by using the 157-3720 Valve Seat Cutter. Refer to Specifications, RENR2401, "Cylinder Head Valves" for the finished diameter of the valve guides and valve seat inserts.

2. Check the protrusion of the valve guides. The valve guides should protrude 14.85 to 15.15 mm (0.585 to 0.597 inch) above the valve spring recess.

3. Repeat the procedure for the remaining valve guides.
