how to test chainsaw flywheel Related Question:
How do you tell if a flywheel magnets are getting bad?
Be sure the magnet you are testing is rotated away from the magneto when testing takes place. Hold the screwdriver against the magnet, if the magnet pulls the screwdriver in, the magnet is fine. If it seems weak or does not pull the screwdriver in, the magnet needs to be replaced.
Can a flywheel go bad on a chainsaw?
It is not common for a flywheel to go bad, the only one I have ever changed was on a Harley where the magnets came unglued. If a screwdriver or wrench sticks to it good it should be fine. You can try disconnecting the kill switch to try and see if it is faulty or the kill wire has the insulation chafed off or pinched.
Can a 2 stroke flywheel go bad?
The magnets as North and South on a Flywheel. They are usually even labeled, at least in most Stihls. If they are no longer N/S, even if they have magnetism, they won’t make a spark. So yes, it can occur.
Can a flywheel lose its magnetism?
Most motorcycles use composite magnets in the flywheels. If you strike them, they will shatter. Even if the magnets are iron, striking the magnets can cause you to lose what magnetism you have, and you will probably be unable to duplicate the process to properly reinstate the correct amount of magnetism.
Can a bad flywheel cause misfire?
What flywheel are you using, stock or aftermarket? The flywheel imbalance would have to be so bad that you wouldn’t dare go over about 3000 rpm, and even than not likely to trigger a misfire. However, bad crank sensor, loose sensor, or bad wiring would.
What causes weak spark on a chainsaw?
A weak spark on a Husqvarna chainsaw can be caused by one of these misfiring components in the ignition system. Properly maintaining and cleaning the saw on a regular basis will prevent most spark issues. Most problems can be isolated easily and fixed with a few simple tools and parts.
Can a flywheel go bad?
Bad Flywheel Symptoms. Unfortunately, flywheels do not last forever. They gradually become worn as they are consistently used in the vehicle. If your flywheel becomes too worn out or damaged, there will be some noticeable symptoms that you won’t be able to ignore.
What does a damaged flywheel sound like?
Noise. The classic and most obvious symptom of a cracked flexplate involves the sound it makes while the engine is running. Descriptions of the sound include clanking, chirping and a light knocking. The reason for the sound involves the flexplate’s location and its function.
Can a rusty flywheel cause no spark?
Rust on the flywheel won’t cause a no-spark problem. However, what caused the rust (excess moisture) could potentially soak into the windings of the stator and lead to a few wraps shorting out. Once that happens, then you could easily have a loss of spark.
Should magneto touch flywheel?
The magneto should not touch the flywheel. In fact, you have to adjust the gap between the coil and flywheel magnets so that the flywheel magnet lines up directly with the magnetic coil and feeler gauge tool.
Will rust on flywheel magnets will cause an ignition system to fail?
Conventional thinking is that when there’s rust on the flywheel, it gets in the way of the spark. All you have to do is clean the flywheel, and you’ll be up and running. Experts have debunked that theory, though, saying that rust has no impact whatsoever on a magnetic field.
How do you make a flywheel magnet stronger?
“Take the magnet which has lost its power and stroke it with the stronger magnet. Linear strokes in a single direction will realign the electrons within the magnet, which will help its strength to increase. Stroke the magnet for around 15 minutes, and check to see if the strength has returned.”
How do I know if my clutch or flywheel is gone?
When you step on your clutch, you expect to feel a smooth pedal that pushes down as you press upon it. If your flywheel is going bad, a smooth pedal is not what you will feel. You may feel vibration as soon as you place your foot on the clutch or when you press down on the clutch.
Can a bad flywheel cause starting problems?
The starter gear is making noise and is the most common problem. It’s less common that the teeth of the flywheel have been worn down. The starter gear can’t grind against the flywheel because of this.
How do I know if my chainsaw spark plug is bad?
If it’s not producing any sparks at all, your chainsaw needs a new plug. If there are only a few sparks coming out of one side of the electrodes but none on the other side, it’s not bad enough for you to worry about, but it will affect your performance.
