Removal Procedure
1. Remove the left or the right valve rocker arm cover.
2. Remove the valve rocker arms and the push rods.
Important: Rotate the engine so that the piston in the cylinder being worked on is at top dead center before removing the valve locks. This will
eliminate the possibility of the valve accidentally falling inside the cylinder.
3. Remove the spark plug.
4. Install the J23590 to the spark plug port and apply compressed air in order to hold the valves closed.
