Spark Plug Inspection

Tightening Torque

The condition of the spark plugs will indicate abnormal engine conditions in most cases. They are very important
engine components and are very easy to check. The spark plugs should be removed and inspected periodically. If
the electrode has some erosion or any foreign deposits, you should replace the plug with a NEW specified spark
plug.
Both spark plugs will normally have the same insulator color. The normal color is a medium tan. If for some
reason, your spark plugs are coloring different, call your Ridley Dealership for information. Do not attempt to
diagnose the problem yourself. Have the dealer determine what is wrong, if anything.
Before installing new spark plugs, clean the gasket surface. Ensure that the new spark plug’s threads are clean
and undamaged. Place a small drop of clean engine oil on the spark plugs threads before installing. Tighten the
spark plugs to the specified torque value.
CAUTION:
Do not over-tighten or under tighten the spark plug. Loosened plugs can cause pre-ignition because the heat is not
dissipated though the threads. Extensive tightness can damage the threads of both the cylinder head and spark plugs.
