Dual mass flywheel failure

What is a failing dual mass flywheel? Are dual mass flywheels durable? Can you replace a single mass flywheel? What would cause a dual mass fly wheel to fail?

Once you’ve determined that your dual mass flywheel is ba you have a couple of options: 1. Replace the OE dual mass fly wheel with an OE-spec replacement.

A measure of unjust criticism is levelled at the dual-mass flywheel, which is often charged with being more susceptible to failure than a conventional clutch. The dual mass flywheel-product of downsizing. The tendency of the auto industry to build evermore powerful engines lead to the problem of transferring that power from the engine to the transmission. This meant that a bigger, more powerful engine, needed a bigger flywheel and clutch set.

The springs of the flywheel punched through the case and caused major transmission damage to the DSG. This car will need a new DMF and a. A smaller-diameter flywheel bolts to the engine and sits inside of a drum-brake-like outer flywheel.

The smaller flywheel engages the larger one via a set of springs.

Dual Mass Flywheel Problems A dual-mass flywheel is a two-part unit. The engineer could move the fly wheel back and forth, clearly the unit had excess movement between the primary and secondary flywheel on the centre bolts, the fixing stud holes had clearly excessively stretched.

Somewhat ironically, and despite the fact that the primary purpose of dual mass flywheels is to reduce engine vibrations, excessive vibration that may or may not be accompanied by “clunking”, “thudding”, or other mechanical noises is usually the first symptom of a failed or failing dual mass flywheel. A failing dual mass flywheel will first rattle when depressing or releasing the clutch, then proceed to exhibit symptoms similar to clutch chatter even after full engagement.

A dual - mass flywheel is a rotating mechanical device that is used to provide continuous 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.

An OE-spec replacement dual mass flywheel will restore the vehicle’s stock performance and feel. It is known to make light rattling noise when the engine is cold.

It is recommended by many technicians that dual mass flywheels are replaced at every clutch change. Still, excessive clutch slip can put undue stress on the dual - mass flywheel and reduce its operating life. Once the work is complete ensure that the clutch works correctly and that the gears can be selected easily from a standstill.
