Removal Procedure
Important:
*
Before removing the valve locks, rotate the engine so that the piston in the cylinder you are working on is at top dead center (TDC). This
will eliminate the possibility of the valve accidentally falling inside the cylinder.
*
Loosen the spark plug, and clean any dirt and/or debris from the spark plug recess area before removing.
1. Remove the spark plug. Refer to Spark Plug Replacement (See: Tune-up and Engine Performance Checks/Spark Plug/Service and Repair).
2. Remove the rocker arm. Refer to Valve Rocker Arm and Push Rod Replacement (See: Rocker Arm Assembly/Service and Repair).
3. Install the J 22794 into the spark plug port. Apply compressed air in order to hold the valve in place.
4. Using caution so as not to damage the valve spring or valve spring dampener, compress the valve spring using the J 5892-D (1) and the
EN-47823 (2).
