5.7 Spark Plugs
NOTICE
Make sure service personnel are qualified to perform electrical and
mechanical service.
The generator set has six spark plugs, all accessible from the top of the engine. The
spark plugs must be in good condition for proper engine starting and performance.
A spark plug that fouls frequently or has heavy soot deposits indicates the need for
engine service.
1. Set the generator set control to the Off position before checking the spark
plugs.
2. To prevent cross-threading a spark plug, always thread it in by hand until it
seats. Torque the spark plug to 38 Nm (28 lb-ft).
3. Return the generator set control to the desired setting when finished performing
maintenance.
