Installing Scooter Engine Parts: Spark Plugs Installing Scooter Engine Parts: Spark Plugs
Knowing about the different scooter engine parts will help you keep your scooter in top running condition yourself. Working on some of the simpler projects yourself will not only save you a lot of money, but give you a working knowledge of the different scooter engine parts in the event you break down on the road. One of the easier tasks of maintaining your scooter engine is changing, and installing, new spark plugs. Here are the steps to take to install this type of scooter engine parts.
Step 1 - Remove Cables from Battery
Before working on any type of electrical part of your scooter, disconnect the wires from the battery. You will need a socket wrench with the appropriate socket. Remove both of the cables so that there will be no accidental crossing of wires.
Step 2 - Pull Plug Wire
If you have used the scooter a lot since the last time the spark plug has been changed, you will need to be careful about pulling the wire. Inside the wire is a small copper electrode that can be easily ripped from the inside of the wire end. This will mean that you not only are going to replace the spark plug, but also replace the plug wire. Use a wire puller that fits over the head of the plug and pull gently. You may need to twist it a little to work it loose from the spark plug.
Step 3 - Loosen Spark Plug
The spark plug will be visible on the side of the engine casing after you remove the wire. You will notice that there is a nut on the body of the spark plug where it rests on the engine. Use a spark plug socket, and a socket wrench, to loosen the spark plug. Again, be careful that you do not break the end off the spark plug. Since the end is usually made out of ceramic, it will break if too much torque is applied.
Step 4 - Remove Plug and Clean Out
After you loosen up the spark plug, remove it and set it aside. Use some compressed air and blow out the spark plug chamber to make sure there is no debris that may have fallen in.
Step 5 - Gap New Spark Plug
A new spark plug will need to have the correct gap setting. A gap setting tool will help you bend the electrode on the end to the correct setting. Check the manufacturer's recommendation for your particular engine size.
Step 6 - Install New Spark Plug
With the spark plug gapped to the specifications, you can now install it. Line up the threads and carefully screw in the plug with your fingers. Tighten it as much as you can with your fingers before you use the socket again. Snug the the spark plug without overtightening.
Step 7- Snap Wire on and Connect Battery
Place the end of the wire on the tip of the plug and slide it into place until it snaps on. Make sure it is tight. Connect the cables back onto the battery and you are ready to go.
