2.
Remove spark plug boot. Be careful
not to tear insulation or wire.
3.
Unscrew the spark plug
counterclockwise from the engine by
the spark plug wrench provided. There
is limited space for the wrench to turn.
Use both rows of holes in the spark plug
wrench to gain leverage to loosen the
plug.
4. Visually inspect the spark plug for
cracks or excessive electrode wear.
Replace as necessary.Remove the
carbon. The porcelain insulator around
the center standard electrode of spark
plug should be a medium-to-light tan
color.
5. Measure the plug gap with a wire
thickness gauge. The gap should be
0.6-0.7 mm (0.024-0.028 in).
6. If re-using the spark plug, use a wire
brush to clean any dirt from around the
spark plug base then re-gap the spark
plug.
7. Screw the spark plug back into the
spark plug hole using the spark plug
wrench. Do not over-tighten spark plug.
Recommended tightening of spark plug
is 1/2 to 3/4 of a turn after spark plug
gasket contacts spark plug hole.
Spark Plug Torque: 17.5 N*m
(1.75kgf*m, 13 lbf*ft)
NOTE:
If a torque wrench is not
available when installing a spark plug, a
good estimate of the correct torque is
1/4-1/2 turn past finger tight. However,
the spark plug should be tightened to the
specified torque as soon as possible.
8. Reinstall the spark plug boot and spark
plug cover.
9. Reinstall the access panel and tighten
the bolts.
1) put the screw #1 & 4 in the access
panel, but donot tighten it fully.
2) put the screw #3 & 6 in the access
panel, but donot tighten it fully.
3) put the screw #2 & 5 in the access
panel, but donot tighten it fully.
4) tighten all screws well
