3. Position the piston of the cylinder being serviced at the bottom of the stroke.
4. Install the special tool between the valve spring coils to protect the valve stem seal from damage.
5. CAUTION: The camshaft roller followers must be installed in their original locations. Record the camshaft roller follower locations. Failure to follow these instructions may result in engine damage.
NOTE: Do not allow the valve keepers to fall off the valve or the valve may drop into the cylinder. If a valve drops into the cylinder, the cylinder head must be removed.
NOTE: It may be necessary to push the valve down while compressing the spring.
NOTE: The 3 rearmost camshaft roller followers on the RH side must use special tool 303-567 in the same manner as is shown in the illustration.
