Description

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 vibration. The vibration reduction is achieved by accumulating stored energy in the two flywheel half masses over a period of time but damped by a series of strong springs, doing that at a rate that is compatible with the energy source, and then releasing that energy at a much higher rate over a relatively short time. A compact dual-mass flywheel often includes the whole clutch, including the pressure plate and the friction disc.

Defective Symptoms

Diagnosing a failing dual mass flywheel can be a little tricky since most of the symptoms could also mean issues with the clutch itself. A definitive assessment will involve visual inspection of all components, but if you have any of these issues, then your flywheel could be the culprit.

Noise. If you hear a lot of rattle or banging sounds from the bell housing, most likely the DMF has failed. These noises can be very loud and it should be replaced as soon as possible.

Slipping. When a clutch is slipping due to wear or otherwise not being up to the capacity to the demand placed on it, you get a burning smell like that of burnt bread and gear oil mixed together. This usually happens first in the higher gears due to the higher gear ratios and increased wind resistance. If you do NOT smell the facings burning up when this is happening, it is your dual mass flywheel that is slipping and it needs to be replaced.

Vibrations. These vibrations can usually be felt on the floor of the car and are due to the failure of the springs and other internal components. This leads directly to the flywheel’s inability to dampen the tremors with use and it must be replaced.

Again, if you have any of these problems, it's time to visually inspect the clutch and flywheel.

Visual Inspection of a Dual Mass Flywheel

• Check the friction surface for excessive heat checks and scoring. Discard if excessive.
  Check for excessive grease loss due to overheating. The internal springs are packed in grease.
• Check for visible damage including the ring gear, and other parts found inside the bell housing.
• Check the rotational free play. Move the secondary plate (the one the pressure plate bolts up to) all the way to the left and mark the gear tooth. Move the plate all the way to the right and mark that gear tooth. There are specifications for each individual dual mass flywheel, but if the left to right play is more than an inch, it’s almost always time to replace it.
• Check for secondary plate rock. Grab the secondary plate on each side (180 degrees apart) and push one side in and see if the other side comes up. If you are able to rock it, it is no longer serviceable and must be discarded.
