Recommended tightening torque
^
First, tighten the spark plug finger tight. Once the gasket reaches the cylinder head, use a plug socket and torque wrench to tighten.
Alternate Angle Method:
^
On plugs with crush washers: If the plug is new, insert the plug until the washer makes contact. Then, using a ratchet, rotate the plug a further 90
degrees.
^
If the plug is used, insert the plug until the washer makes contact. Then, using a ratchet, rotate the plug a further 30 degrees.
USING THE CORRECT SPARK PLUG SOCKET
^
Care must be taken during installation that the spark plug socket is not slanted and does not slip causing insulator breakage.
^
The following are qualities required in a wrench:
1.
Fits the spark plug "hex" properly.
2.
The inner space must be large enough to avoid contact with the insulator.
3.
The plug socket must completely cover the "hex" portion of the metal shell.
4.
A six-pint socket is preferable as it is less likely to slip than a twelve-point.
