d. If necessary, the gap can be adjusted by bending the
side electrodes, paying attention to the strength during
adjustment.
e. Clean the surface of the spark plug gasket and the joint
surface, and wipe off the dirt on the thread.
f. First screw it back to the engine by hand, and then use
the tool to turn it clockwise to the standard torque.
Model: LMAR8A-9
Resistance between the terminal screw and the center
electrode: 3
～
7.5kΩ
Clearance: 0.8-0.9mm (0.031-0.035in)
Torque: 14N.m (1.4kgf.m, 10 lbf.ft)
3. Refer to the steps to remove the spark plug to
restore all parts.
●The vehicle must be parked on a flat and stable ground or a
lifting platform.
●The operation can only be performed after the engine has
cooled down completely.
●Do not pull or knock the center electrode.
●If the replacement of inappropriate heating value or inferior
spark plugs causes engine damage, it is not within the scope
of the three guarantees.
●When installing the spark plug, the torque should not be
too large, and the thread should be screwed in manually
before tightening. If there is no torque wrench to replace the
spark plug, you can turn it by hand until there is resistance
and then rotate it 1/2 turn. For example, if you use an old
spark plug, you can turn it to the standard torque as soon as
possible.
●Pay attention and order when removing the plastic buckle
to avoid the buckle from breaking.
