PERIODIC MAINTENANCE AND MINOR REPAIR
To install the spark plug
1. Measure the spark plug gap with a
wire thickness gauge and, if
necessary, adjust the gap to
specification.
Spark plug gap:
0.5 ~ 0.7 mm
2. Clean the surface of the spark plug
gasket and its mating surface, and
then wipe off any grime from the
spark plug threads.
3. Install the spark plug with the spark
plug wrench, and then tighten it to
the specified torque.
Tightening torque:
Spark plug:
20 Nm (2.0 m•kg)
6-9
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.
4. Install the spark plug cap.
