Is this the time of year when bad spark must be replaced as part of generator tuning?
Sometimes, failing generator spark plugs can be so frustrating. But the actual replacement process is very simple.
So, to save yourself the stress, in this article, China BISON will show you how to change a generator spark plug. Thanks to our instructions and user manual, amateurs will have no problems.
In fact, our first piece of advice is to read the guide before starting the update process, as it often contains information on the correct spark plug type.
The Significance of Replacing Generator Spark Plugs
A generator spark plug is usually located in the engine cylinder head and is designed to create a spark in a small gap that ignites the air and fuel mixture, creating a controlled explosion. This explosion creates pressure and drives a piston, generating power, which is transmitted to the crankshaft and to the output shaft of a generator.
Maintaining the efficiency and durability of your generator is highly dependent on replacing generator spark plugs. Inefficient fuel usage, diminished power production, and potential engine harm can result from a worn or damaged spark plug.
Items you will need to change the generator spark plug
- Spark plug with the proper spacing
- The brush and towel must be clean.
- 3/8″ and 5/8″ spark plug socket
- Gloves for protection
- Phillips and flathead screwdrivers
- Set for gapping spark plugs
- Ratchet
How to change generator spark plug step by step?
- Discover the spark plug: The first (and frequently most difficult, especially if this is your first time) step is to find the spark plug. It is frequently buried beneath a detachable case and covered by a spark plug boot. Although the alternator spark plug location varies, it is typically in the engine’s cylinder head. This can be done by removing the air filter or protective cover. In some cases, the spark plug may be in a hard-to-reach area, requiring the removal of other components or the engine disassembly. On newer inverter generators, it is located behind the side panels. In these cases, it is advisable to consult the generator’s owner’s manual for specific instructions.
- Disconnect spark plug wire: Once you’ve discovered the location of your old plug, you must unplug the wire that is connected to it. You must have access to the boot of a spark plug wire to do so safely. Twist the boot in either way and pull off at the same time once you have a firm grip on it.
- Clean the area completely: Check that the old plug and everything surrounding it is clean when you disconnect the wire. Take your time with this because missing the cleaning process might do significant damage to your generator.
- Remove old spark plug: Use a spark plug socket wrench to safely remove the spark plugs from the engine.
- Watch out for the new spark plug: Before installing your new spark plug into your generator, make sure you have the correct model, size, and gap.
- Installation of a new plug: Once you’ve determined that your plug has the proper gap, you can install it. Insert the replacement spark plug by hand into the spark plug housing and tighten it with the socket wrench, taking care not to over-tighten.
- Replace the plug wire: After you’ve safely installed your new spark plug, reconnect the wire. Again, take the spark plug wire boot and slip it over the head of the plug. Then, press it until it is completely inserted.
BISON safety tip: Before maintaining or repairing any power equipment, disconnect the spark plug and battery wires. Wear proper safety eyeglasses and gloves to protect you from hazardous materials and debris.
