Flywheel replacement & repair made easy

The flywheel is fitted on the engine's crankshaft. It acts as a plate onto which the clutch's pressure plate grips, as such when the clutch is engaged it allows for power to be transferred from the engine to the car's gearbox. Subsequently transferring engine power to the wheels. At the same time the flywheel also has a function as a component that ensures a continuous and balanced power delivery from the engine. Apart from this the flywheel's starter ring gear (the teeth along the outer edge) acts as a large gear into which the starter motor's gear grips, enabling the starter motor to turn over the engine when you start the car.

*Mechanic will inspect and test the functionality of the clutch and flywheel.
*If necessary, the mechanic will advise if flywheel needs replacing.
*Mechanic separates gearbox from the engine, and will replace the flywheel if necessary.
*The mechanic will advise if other components like the clutch plate need to be replaced, and can provide a quote.
*The mechanic will rejoin the engine and gearbox.
*Mechanic checks the operation of the flywheel and clutch combination and will test drive car.
*Mechanic will make adjustments if necessary.

On average, flywheel replacement times can range from 3.5 to over 7 hours with an average of around 5 hours. The time that the job takes will depend on a number of factors, like your vehicle's make and model, year, as well as other factors.

A flywheel replacement is normally recommended when changing the clutch. In most cases one will find that when the clutch is worn or damaged it may have affected the flywheel. Not replacing the flywheel at the same time may then lead to damage to the new clutch. Hence the need for a replacement at the same time, which is recommended by most mechanics.

Signs of juddering or vibrations when depressing clutch pedal are normally a sign that there may be something wrong with the flywheel, especially if problems appear in first gear. Apart from that, the flywheel's starter ring gear (the teeth around the out edge of the plate) can get damaged due to wear. Sometimes a tooth will break, preventing the starter motor's gear to grip properly leading to starting problems on the car.

Cars nowadays are fitted either with a dual mass flywheel or the more conventional flywheel. The dual mass flywheel is more prone to wear, and in general will have to be replaced more often over the lifetime of a car. An option that is open for some cars is the conversion of the dual mass flywheel to a solid flywheel, which is cheaper.

Of course, if you suspect that you may need a flywheel replacement but are not sure, it is advisable to have a professional mechanic assess the situation first. In any case, always make sure to follow the manufacturer's guidelines.

If you suspect there is any issue with your vehicle's flywheel or there are concerns about its condition, book an inspection with a professional mechanic with immediate effect, driving the vehicle may lead to further complications and will eventually leave you stranded.

During an MOT test, the clutch system is not checked so it shouldn't fail the test. However, if the flywheel is faulty it could cause other problems such as engine misfire that could result in an MOT failure.

Yes, in certain cases you will need to replace the flywheel at the same time as the clutch. In particular if your vehicle is fitted with a Dual Mass Flywheel (DMF) you will need to replace it at the same time as the clutch. In other cases, when replacing the clutch, it's recommended to get it inspected for cracks or noticeable damage by a qualified mechanic and get it replaced if needed.

If the flywheel goes the engine will generally not be able to start, will stall or not run properly. The flywheel assists in keeping the engine running smoothly by storing energy and providing momentum, it therefore plays a pivotal part in ensuring the drivetrain runs smoothly.

Dual mass flywheels are so expensive because they are a relatively new technology, and offer a number of advantages over traditional single mass flywheels. Some of these advantages include improved engine performance, smoother engine operation, and reduced engine vibration.

There are several symptoms that may indicate that your clutch or flywheel is going bad, including:

• A grinding noise when shifting gears
• A burning smell coming from the clutch
• Difficulty shifting gears
• Clutch pedal sticking to the floor

If you notice any of these symptoms, it is important to have your vehicle inspected by a qualified mechanic as soon as possible.

A typical clutch and flywheel will last around 60,000 - 100,000 miles, although this will vary depending on driving style and conditions.

A flywheel is connected to the clutch. A dual mass flywheel is a type of flywheel that uses two masses connected by a spring. The two masses rotate at different speeds, which allows for smoother operation and reduced vibration.
