Always use a spark plug wrench when re- moving or reinstalling the plug.

Be sure the gasket is in good condition, and screw the plug in tightly. Do not tighten more than enough to compress the gasket to seal the plug and assure a good heat transfer between the plug and the cylinder head. Tighten the plug 1/2 to 3/4 turns past finger tight.

Set gap at .O25-inch.

Replace a defective plug with a new plug. See your International Harvester dealer for a correct replacement plug.
