Removal and Installation 1. Remove the roller followers. For additional information, refer to Camshaft Roller Follower in this
section.
2. Remove the spark plug (12405) from the applicable cylinder.
3. Position the piston (6102) of the cylinder being serviced at the bottom of the stroke.
4. CAUTION: If air pressure has forced the piston to the bottom of the cylinder, any
loss of air pressure will allow the valve to fall into the cylinder. If air pressure must be
removed, support the valve prior to removal.
Use compressed air in the cylinder to hold both valves in position. 5. Using the special tool, compress the valve spring (6513). SECTION 303-
