What does flywheel key do?
Q. Why is my lawn mower turning over but not starting? The most likely reason is bad gas. Gas that sits for many months during the off-season will eventually break down, gumming up the fuel line and carburetor in the engine and preventing it from starting.
What is the function of the flywheel in a lawn mower?
The flywheel stores energy when torque is applied by the energy source, and it releases stored energy when the energy source is not applying torque. Today, the fins on flywheels act almost like fans, cooling the engine by distributing air around the engine block.
What holds the flywheel in place?
Virtually every flywheel or rotor is attached to the crankshaft by a taper on the crank, which matches the flywheel. Torque from the fixing bolt holds the flywheel securely on the shaft. Pulling a flywheel or rotor looks easy enough.
How do you remove a broken key from a flywheel?
Flywheel brakes are used to stop the flywheel from turning when a clutch has been disengaged and the motor is shutdown. Typically, these brake systems are installed on stamping, forging and metalforming equipment. Flywheel brakes are required for presses due to safety regulations.
What are the 4 functions of flywheel?
Functions of Flywheel:
- #1. Engine Balance.
- #2. Engine Start.
- #3. Drivetrain Stress Reduction.
- #4. Engine Speed Soothing.
- #5. Weight Manipulation.
How do I know if my flywheel is broken?
It provides mass for rotational inertia to keep the engine in motion. It is specifically weighted to provide balance for the crankshaft.
What are the 2 main purposes of the flywheel in a small gas engine?
The flywheel has a small metal part, called a key, that keeps it in the proper orientation on the crankshaft to perform this last function. The key can shear when the mower hits a rock or other foreign obstacle, causing the mower to stall and misfire.
How do I keep my flywheel from moving?
The flywheel is firmly bolted to a flange on the transmission side of the crankshaft inside the bell housing. On the side facing the manual transmission, the surface is machined flat for the clutch disc to grab onto.
What is attached to flywheel?
It is attached to the end of the engine’s crankshaft where it bolts to the transmission.
How do you remove a sheared flywheel key?
You can try tapping a nail on one end of the key, drilling into the center of the key and removing it with a nail, or even heating the key up with a blowtorch and letting it cool repeatedly to loosen it. Remember that damaging the key is a far better alternative than damaging the shaft or other part around the key.
What happens when flywheel key breaks?
Turn the key so that the keyway slot is in the exact position it was in when you inserted the key; this is the correct position for the pin tumblers to align in the cylinder. With your other hand, use the tip of your finger to push firmly on the face of the plug next to the key.Gently twist and pull the key out
What are the main functions of flywheel?
flywheel, heavy wheel attached to a rotating shaft so as to smooth out delivery of power from a motor to a machine. The inertia of the flywheel opposes and moderates fluctuations in the speed of the engine and stores the excess energy for intermittent use.
What is the function of a flywheel and also give its practical application?
It is used to store energy when available and supply it when required. To reduces speed fluctuations. To reduce the power capacity of an electric motor or engine. Applications of the flywheel can be broadly divided into two parts based on the source of power available and the type of driven machinery.
How do you check a flywheel?
So, to know if your vehicle’s starter or flywheel is bad, take time to observe your car when you start it. If you turn the vehicle’s ignition switch ON and it produces a whining noise without the engine cranking, the vehicle’s starter gear is likely failing to engage the flywheel.
How do I know if my starter or flywheel is bad?
You may start to experience grinding noises from the pressure plate and eventually, the flywheel other parts in the clutch assembly will overheat and cause them to warp or even crack. Finally, if the clutch and flywheel are not replaced, you simply won’t be able to shift at all.
What is the purpose of a flywheel in a small engine?
The flywheel stores energy when torque is applied by the energy source, and it releases stored energy when the energy source is not applying torque. Today, the fins on flywheels act almost like fans, cooling the engine by distributing air around the engine block.
What are the 3 functions of flywheel?
Functions of Flywheel
- Engine Balancing: because the pistons are offset from the centre of the crankshaft vibration and wobbles occur.
- Engine Start: the flywheel plays another role while starting the engine.
- Drivetrain stress reduction: is another function of a flywheel, achieved by stabilizing the engine’s movement.
What are the 2 types of flywheels?
Types of Flywheel
- Solid disk flywheel.
- Rimmed flywheel.

- #5. Weight Manipulation.
How do you hold a flywheel in place?
DO NOT use a washer with this flywheel bolt. Tighten all bolts evenly, xbc turn at a time in a crisscross pattern until flywheel is completely drawn-up to the crankshaft
How do you lock a flywheel?
The starter motor engages the starter ring on the edge of the flywheel to begin engine rotation. Most importantly for drivers, the flywheel connects the engine with the transmission via a clutch to transfer power to the wheels.
What are the parts of a flywheel?
Following are the parts of a flywheel:
- Flywheel housing.
- Springs.
- Planetary wheel.
- Axial sliding bearing.
- Radial sliding bearing.
- Ring gear.
- Locking pinhole.
- Support disk.
Is clutch attached to flywheel?
Virtually every flywheel or rotor is attached to the crankshaft by a taper on the crank, which matches the flywheel. Torque from the fixing bolt holds the flywheel securely on the shaft. Pulling a flywheel or rotor looks easy enough.
How do you fix a key on a flywheel?
A soft key allows the flywheel to move on the crankshaft when your mower blade hits a tree root, an old stump, a large dried clod of dirt, etc. If the mower blade is loose, that will cause enough shock to shear the flywheel key, too.
