11.3.2 Replacing, cleaning and setting the sparking plug
Procedure:
In order to deliver good performance, the sparking plug must have a correct electrode gap
and be free from deposits.
1. Detach the sparking plug connector and remove any dirt near the sparking plug.
2. Unscrew the sparking plug using a 16 mm (5/8 inch) sparking plug spanner.
3. Check the sparking plug. Replace the sparking plug if it is damaged, extremely dirty, the
sealing washer is in poor condition or the electrodes are worn.
4. Measure the electrode gap on the sparking plug with a wire feeler gauge. Correct the
electrode gap, if required, by carefully bending the side electrode. Target electrode gap:
0.6 - 0.7 mm (0.024 - 0.028 in)
5. Carefully screw in the sparking plug by hand in order to avoid stripping the thread.
6. Tighten the sparking plug after mounting with a 5/8-inch sparking plug spanner in order to
compress the washer.
7. A new sparking plug should be tightened by an additional 1/2 turn after fitting in order to
compress the washer.
8. A used sparking plug should be tightened by an additional 1/8 to 1/4 turn after fitting in
order to compress the washer.
9. Place the sparking plug connector on the sparking plug.
NOTE:
A loose sparking plug can overheat and damage the engine.
A sparking plug that is too tight can damage the thread in the cylinder head.
