Spark Plug Maintenance

Checking the Spark Plug

1. The use of compressed air is necessary when trying to remove the spark plug. This would blow out the foreign matters all over the base.

2. It is proper to remove the wire from its terminal boot rather than pulling onto the spark plug wire itself.

3. To avoid confusion and easy identification of wires, an organized system can be implemented such as the use of numbered clothespin. This can be clipped on the wire which makes the task uncomplicated.

4. A deep socket that contains a magnetic or rubber retainer is preferable to use.

5. Make sure to classify the spark plug with its appropriate cylinder.

6. Check the spark plug for potential cylinder failures.

7. Make the plug clean through a solvent and let it dry with the aid of compressed air. Likewise, ensure that the insulator is free from carbon, paint as well as oxide. These stuffs are formed from the fuel additives.

8. When there is a rounded-off electrode, it is required to make it filed flat.

9. Using a steel brush, remove particles formed in the threads such as carbon and rust.

10. Ensure the width of the gap using a round spark plug wire type gauge. Apply the necessary gap adjustments between the electrode and ground to their correct arrangement and specifications, normally, in the range of .022 to .040 inch.

 

Setting up Spark Plugs

1. Make sure that both the plug threads and cylinder threads are dirt-free.

2. Even if you have new plugs, it is still necessary to check the gap setting.

3. For plugs that require head gaskets, be sure that you install new ones at all times.

4. With the use of hands, make the plugs tighter. After that, using a torque wrench, re-torque the plugs according to the recommendation of the manufacturer. It may vary whether in cast iron heads or aluminum head from the range of 10 ft. lbs. to 35 ft. lbs.

5. Check the spark plug cable. Ensure that it is securely fitted in the plug terminal.

6. Regular inspection must be done on plugs. A lot of manufacturers suggest checking these components every 16,090km or 10,000 miles.
