Installing the Spark Plug
Important:
Ensure that the gap between the side
and center electrodes is correct before installing
the spark plug.
1. Thread the spark plug clockwise into the
spark-plug hole by hand.
Note:
Avoid cross-threading the spark plug with
the threads of the spark-plug hole.
2. Rotate the spark plug clockwise using a 21 mm
(13/16 inch) spark-plug wrench until the plug
and sealing washer are seated
3. Tighten the spark plug as follows:
•
When installing an in-service spark plug,
tighten the plug an additional 1/8 to 1/4 turn.
•
When installing a new spark plug, tighten the
plug an additional 1/2 turn.
Important:
A loose spark plug may cause
the cylinder to overheat. An over-tight spark
plug may damage the threads in the cylinder
head.

spark plug (Figure
