MAINTENANCE
SPARK PLUG REPLACEMENT (FIG 16)
To ensure proper engine operation, the spark plug must be properly gapped and free of deposits.
1.
Loosen the maintenance cover screws and remove the maintenance cover.
2.
Remove the spark plug cap.
3.
Clean any dirt from around the spark plug base.
4.
Use the wrench to remove the spark plug.
5.
Visually inspect the spark plug. Replace it if the electrode is worn, or if the insulator is cracked, chipped or fouled.
Clean the spark plug with a wire brush if it is to be reused.
6.
Measure the spark plug electrode gap with a wire-type feeler gauge. The gap should be 0.024-0.028in (0.6-
0.7mm). Correct as necessary by carefully bending the side electrode.
7.
Check the sealing washer is in good condition, and thread the spark plug in by hand to prevent cross-threading.
8.
After a new spark plug has been seated by hand, it should be tightened 1/2 turn with a wrench to compress its
washer. If a used plug is being reinstalled, it should only require 1/8 to 1/4 turn after being seated.
9.
Reinstall the spark plug cap on the spark plug securely.
10.
Reinstall the maintenance cover.
CAUTION:
A loosen spark plug can overheat and damage the engine. Overheating the spark plug can damage the
threads in the cylinder head. Never use a spark plug with an improper heat range.
