The flywheel key is a rectangular metal peg that keeps the crankshaft and flywheel aligned when you tighten the flywheel nut. If the mower blade hits an object with enough force to knock the flywheel out of alignment, the flywheel key breaks, protecting expensive parts such as the crankshaft from damage. FLYWHEEL BRAKE The brake applies friction to the circumference of the flywheel helping to stop it quickly.
FLYWHEEL MAGNET FOR IGNITION. A permanent magnet is mounted on the flywheel. Tecumseh Flywheel with fins…. The flywheel may have fins on it that act as a fan when the flywheel spins, or it may have a separately molded fan that is mounted to it. FLYWHEEL MAGNETS FOR CHARGING STATOR. A flywheel may have additional magnets mounted to its underside which rotate around a stator coil for the purpose of generating electric current.
If you’ve ever overheated your flywheel or driven too long with a clutch that was on its last legs, it is very likely that you have damaged the flywheel due to excessive heat or metal on metal wear. Since the starter motor pinion material is softer than the flywheel, it is highly unlikely that the starter would ever damage the flywheel teeth. Flywheel resurfacing is a process where it is run through a machine to make the surface of the flywheel smooth and take out any indentations that could cause the noise.
what does a chainsaw flywheel do Related Question:
How does flywheel work on chainsaw?
The flywheel spins when the crankshaft turns, and when it’s stuck you won’t be able to use your chain saw. A chain saw’s starter rope connects to a pulley, which, through a recoil spring and two pawls, connects to the flywheel. The flywheel connects to the crankshaft through a thin metal piece called the key.
What is the purpose of the flywheel?
In automobile engines the flywheel serves to smooth out the pulses of energy provided by the combustion in the cylinders and to provide energy for the compression stroke of the pistons.
What does a small engine flywheel do?
The flywheel on your small engine was originally designed to store the momentum from combustion to keep the crankshaft turning in between the engine’s power strokes. Flywheels on today’s small engines serve several other purposes. The fins help cool the engine by distributing air around the engine block.
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.
How does a flywheel get damaged?
If you’ve ever overheated your flywheel or driven too long with a clutch that was on its last legs, it is very likely that you have damaged the flywheel due to excessive heat or metal on metal wear. Clutches that are worn down to the rivets will damage the flywheel.
Does a flywheel always spin?
A flywheel is a weighty wheel that requires plenty of force to rotate on its axis. When the wheel is in motion at a high speed, it will keep spinning unless you stop it by applying lots of force.
Can you start an engine without a flywheel?
Starting it without a flywheel is not a good practice, and not an easy feat unless you are good at pull starting a V-8… Also the result in an engine that requires the flywheel for balance could be very harmful. The torque converter does not have to be on the engine though.
Does the flywheel balance the crankshaft?
An internally balanced engine has all the counterweight on the crank. External parts like the balancer and flexplate/flywheel have a neutral balance. They will not affect the other rotating parts.
What is the advantage of a flywheel?
The advantages of flywheel energy storage systems are high efficiency, high energy and power density, and long life. On the other hand, flywheels are more expensive and require more space than batteries and fuel cells. There are also some safety concerns about flywheels rotating at high speeds.
Are flywheels efficient?
A flywheel energy storage system has many advantages for it is running in a high-vacuum environment and has no friction loss, small wind resistance, a cycle efficiency of 85%–95%, long life, and is ecofriendly and free of maintenance.
Can a flywheel damage a starter?
The click noise is the Bendix on the starter, it will click sometimes, if the Bendix don’t work properly it won’t allow the starter shaft to move towards the flywheel, therefore the car won’t start, Flywheel can not damage a starter since they were all new, The starter however can damage the flyheel, in your case the
Are lightweight flywheels worth it?
With a lightweight flywheel, right away you will notice the engine revs more quickly. You free up the horsepower your engine is already making and send it to the rear wheels rather than have it dissipate as parasitic losses. There are other benefits, too.
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 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 flywheel cause no spark?
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.
