Visual Inspection of a Dual Mass Flywheel
  • Check the friction surface for excessive heat checks and scoring.
  • Check for excessive grease loss due to overheating.
  • Check for visible damage including the ring gear, and other parts found inside the bellhousing.
  • Check the rotational free play.
  • Check for secondary plate rock.

Beside this, what are the symptoms of a failing dual mass flywheel?

The failure symptoms of a dual mass flywheel

  • Sense of something hitting the clutch pedal from underneath.
  • Squeaking sound and shake down.
  • Clunking and grinding noise from the engine compartment.

Also Know, do I need to replace dual mass flywheel when replacing clutch? No, you won't burn-out your new clutch plate if you fail to replace the flywheel. Many, (if not most) modern cars have what are called 'dual mass' flywheels. Dual mass flywheels wear. Usually, by the time the clutch plate needs to be replaced, the flywheel also needs to be replaced.

Then, how long does a dual mass flywheel last?

four to five years

How long will a bad flywheel last?

4 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.

How do I know if my flywheel needs to be replaced?

Top 5 Bad Flywheel Symptoms
  1. #1 –Gears Slipping. Often, as you try to change gears while driving, the gears may slip.
  2. #2 – Burning Smell. Aside from gear slippage, you will notice a burning smell that will consume the interior of the vehicle.
  3. #3 – Clutch Chatter.
  4. #4 – Clutch Pedal Vibrates.
  5. #5 – Clutch Drag.

Can a bad flywheel cause starting problems?

The most common problem is that the starter gear has broken and is making noise. The less common of the two is that the teeth of the flywheel have been worn down. This causes the starter gear to not engage properly and grind against the flywheel.

What is the purpose of dual mass flywheel?

A dual-mass flywheel (DMF or DMFW) is a rotating mechanical device that is used to provide continuous energy (rotational energy) in systems where the energy source is not continuous, the same way as a conventional flywheel acts, but damping any violent variation of torque or revolutions that could cause an unwanted

How much does it cost to replace a dual mass flywheel?

So the basic price tag is: Dual mass flywheel: starting from about 300,00 Euros. Clutch set : starting from 100 Euros. Cost of replacement: starting from 150 Euros.

What causes a flywheel to go bad?


Worn starter drive components, worn bushings in the starter, improper shimmed starters on vehicles that use shims, weak batteries and aged equipment cause flywheel problems. Most engines will stop in the same stop each time the engine is shutoff. That causes the same spot on the flywheel to be engaged each start.

Do automatic cars have dual mass flywheels?

A torque converter automatic transmission does not normally need a dual mass flywheel because the torque converter does the job, but a DSG is a twin shaft twin clutch preselector automatic and does need a DMF to protect the transmission from too much sudden torque transfer. The hesitation is not due to 'turbo lag'.

Can a dual mass flywheel be repaired?

If you are fortunate and the flywheel has not been damaged by a worn clutch-plate, its replacement will simply not be deemed necessary. However, increasingly, owners of cars fitted with dual-mass flywheels must foot the bill for replacement, in addition to the cost of a new clutch-plate and its ancillary parts.

How long does it take to change a clutch and flywheel?

To summarize: In the perfect situation, your clutch replacement could take from 4 to 8 hours to complete. Though since most vehicles in need of clutch replacement are not in perfect shape, it can often take between 5 and 10 hours to complete the project, adding more time for less experience on the mechanics part.

Is a flywheel covered under warranty?

Understand that clutch plate is not cover under warranty , but flywheel should comes under warranty .

Which is better dual mass flywheel or solid flywheel?


They tend to be much cheaper than a dual-mass flywheel to replace, and because they are made of one piece they can also be resurfaced if within factory specifications. This is because, unlike single mass conventional clutch and flywheel assemblies, you cannot resurface a dual-mass flywheel when you do a clutch job.

Can a dual mass flywheel be skimmed?

They work fine as long as the engine remains unmodified and the vehicle is not used/abused beyond manufacturers recommendations. 2) In theory it can be skimmed, but it is recommended that you dont, usually you should replace your dual mass flywheel when you replace your clutch.

Can dual mass flywheel cause vibration?

Dual mass flywheels utilize dampener springs to keep the resonant vibrational frequencies of an engine down. However, faulty engine valves and fuel injectors, amongst other things, can cause an increase in engine vibration.

Why are dual mass flywheels so expensive?

The idea is that the rubber creates smoother operation of the clutch release and reduces vibration in modern cars. The main reason these jobs tend to be more expensive than with typical older type clutch jobs is the price of the parts. A standard style flywheel is much more durable so does not often need to be changed.

What is a flywheel on a car What does it do?

A flywheel is a mechanical device specifically designed to efficiently store rotational energy (kinetic energy). Flywheels resist changes in rotational speed by their moment of inertia. For example, flywheels are used in reciprocating engines because the active torque from the individual pistons is intermittent.

How does flywheel and clutch work?


The flywheel is a metal disc which is fitted directly onto the crankshaft between the engine and the clutch. Its purpose is to help provide a smooth transfer of power from the engine to the drive train. In essence, the flywheel gives your vehicle enhanced momentum and a smoother driving experience.

What happens if you don't resurface flywheel?

not resurfacing the flywheel COULD cause the clutch to glaze or not seat right. same idea as not turning the rotors when you do brakes. yep. It's imperative that you resurface and also break the clutch in properly!

Why do dual mass flywheels fail?

Causes of DMF Failure
Beyond normal wear and tear, there's other things that can cause a DMF to fail -- these include: Since the damper springs are designed for a specific torque output, increased torque will eventually lead to a dual mass flywheel failure.
