– NOTE –
Torque indicating handle should not be used for spark plug
removal because of the greater torque requirement.
3. Place spark plugs in a tray that will identify their position in the engine as soon as they are removed.
– NOTE –
Spark plugs should not be used if they have been dropped.
4. Removal of seized spark plugs in the cylinder may be accomplished by application of liquid carbon
dioxide by a conical metal funnel adapter with a hole in the apex just large enough to accommodate
the funnel of a CO2 bottle. (Refer to Figure 32.) When a seized spark plug cannot be removed by nor-
mal means, the funnel adapter is placed over and around the spark plug. Place the funnel of the CO2
bottle inside the funnel adapter and release the carbon dioxide to chill and contract the spark plug.
Break the spark plug loose with a wrench. A warm cylinder head at the time the carbon dioxide is
applied will aid in the removal of an excessively seized plug.
5. Do not allow foreign objects to enter the spark plug hole.
INSPECTION AND CLEANING OF SPARK PLUGS.
1. Visually inspect each spark plug for the following non-repairable defects:
a. Severely damaged shell or shield threads nicked up, stripped or cross-threaded.
b. Badly battered or rounded shell hexagons.
c. Out-of-round or damaged shielding barrel.
d. Chipped, cracked or broken ceramic insulator portions.
e. Badly eroded electrodes worn to approximately 50% of original size.
2. Clean the spark plug as required, removing carbon and foreign deposits.
3. Test the spark plug both electrically and for resistance.
4. Set the electrode gap at 0.015 to 0.018 inches.
INSTALLATION OF SPARK PLUGS.
Before installing spark plugs, ascertain that the threads within the cylinder are clean and not damaged.
1. Apply anti-seize compound sparingly on the threads and install gasket and spark plugs. Torque 360 to
420 inch-pounds.
– CAUTION –
Make certain the deep socket is properly seated on the spark
plug hexagon as damage to the plug could result if the wrench
is cocked to one side when pressure is applied.
2. Carefully insert the terminal insulator in the spark plug and tighten the coupling nut.
