Spark Plug: Testing and Inspection
NOTICE:
^
Never use a wire brush for cleaning.
^
Never attempt to adjust the electrode gap on a used spark plug.
^
Spark plugs should be replaced every 100,000 km (60,000 miles).
1. REMOVE HIGH - TENSION CORDS FROM THE SPARK PLUGS.
2. INSPECT ELECTRODE USING A MEGGER.
-
Using a megger (insulation resistance meter), measure the insulation resistance.
Insulation resistance: 10 M Ohms or more
-
If the resistance is less than specified, proceed to step 4.
3. REMOVE SPARK PLUGS USING A 16 MM PLUG WRENCH.
4. VISUALLY INSPECT SPARK PLUGS.
-
Check the spark plug for thread damage and insulator damage.
-
If abnormal. replace the spark plug.
Recommended Spark Plugs:
GPK20R11 for ND
BKR6EP11 for NGK
5. CLEAN SPARK PLUGS USING A SPARK PLUG CLEANER.
-
If the electrode has traces of wet carbon, allow it to dry and then clean with a spark plug cleaner.
-
If there are traces of oil, remove it with gasoline before using the spark plug cleaner.
Air pressure: Below 588 kPa (85 psi).
Duration: 20 seconds or less.
6. INSPECT ELECTRODE GAP.
-
If needed, correct the electrode gap of new spark plug.
