The Dual Mass Flywheel is a flywheel split into two masses (one primary and one secondary mass), with one mass attached to the engine and the other attached to the input shaft of the gearbox. The two masses are linked by a damper. The damper stops unwanted vibration caused by the torque loads of the crankshaft from getting to the gearbox.

As you keep using the vehicle and cover more mileage (50,000 – 10,000 mileage, or even less), the damper becomes weak as it gets soft. The movement between the two masses increases with increased weakness of the damper. It gets to a point where the flywheel begins to vibrate.

When your car begins to make a maddening noise, or there is a large hole in your gear box with oil pouring out of it, or the car jerks while pulling away, it may be a sign to show you need a DMF change. Book an appointment in the garage and let us check it out for you.



The dual mass flywheel helps ease gear change and make it lighter, smoother, and quieter. It also reduces torsional spikes by separating the crankshaft and the gearbox.

Dual mass flywheel becomes worn the more it’s used. Its noise increases, producing vibrations and strong reverberations felt inside the car. This is a strong notice that you have to change the DMF immediately.

Altering the engine to produce more power than the flywheel is designed to handle could result in DMF failure. Forcing a car to pull more weight than it’s been made for could negatively affect the DMF.

Cars with diesel engines require DMF replacement every time the clutch is changed. Petrol engines, on the other hand, do not require this.
