MAINTENANCE AND LUBRICATION
Minor Maintenance
Spark Plugs
A spark plug with cracked porcelain or damaged threads should be
changed immediately. If the electrodes are badly worn or burned the
plug should also be replaced.
If the spark plug is in good condition, clean it with a clean shop cloth
and/or wire brush. Adjust the gap to the proper dimension using a wire
thickness gauge.
Spark Plugs
Wipe off any water on the spark plug or inside the cap. P ush the cap
down on the plug until it clicks. Use dielectric grease PN 2871066 on
the inside of the spark plug cap to prevent corrosion.
Before installing a used plug, wipe off threads and apply dielectric
grease PN 2871066. Also clean the gasket surface. Install the spark
plug and torque to 18 ft. lbs. If a torque wrench is not available 1/4 to
1/2 t urn past finger-tight is close to the correct torque.
Never attempt to remove the spark plug with a warm engine. The
exhaust system or engine could burn you causing injury.
When installing or removing spark plugs be careful not to
damage the porcelain insulator.
CAUTION
High tension voltage is present in the spark plug wires when the
engine is running. Never touch spark plug wires when the engine is
being cranked or run.
