Dual mass wheel - wear and repair – main image

In modern cars equipped with a diesel engine, one of the most important parts influencing the quality of the engine operation and the comfort of its use is the dual-mass flywheel. It developed in response to the intense increase in interest in diesel engines in passenger cars, the manufacturers of which wanted to convince customers that such an engine is as comfortable and convenient to use as a gasoline engine, and at the same time has a much lower appetite for fuel.

How is a dual mass flywheel built and what function does it perform in a car

The dual-mass flywheel is made of two flywheels connected with each other by a torsional vibration damper. One of these wheels is attached to the car's engine, the other to the gearbox, while the damper connecting them is designed to prevent the transmission of vibrations from the engine to the gearbox. Both wheels are connected to each other by the spring elements of the vibration damper, preventing the transmission of vibrations from the engine to the gearbox. The dual-mass wheel is used not only to ensure smooth engine operation by maintaining its rotational speed during subsequent strokes, but also protects the gearbox and body from engine vibrations. In addition, it allows for smooth transmission of torque from more and more powerful engines to the drive system, which directly affects the comfort of driving. Unfortunately, this part is prone to wear and tear during the use of the car, especially when the vehicle is forced to start and brake frequently. The life of this part is especially not served by the driver's "heavy leg" and dynamic starting or acceleration.

Symptoms of wear of the dual mass flywheel

Initial symptoms of dual mass failure are louder-than-usual engine operation and vibrations in the gearbox. Then there is knocking and other noises from the engine as it starts or stops. In addition, uneven engine operation or vibration is felt, which may be transmitted to the body of the vehicle. If these symptoms are observed, repair this part, as damage to the mass flywheel can damage the clutch or, worse, even damage the gearbox.

Exchange

Replacing a dual mass flywheel is a significant expense, depending on the type of drive unit and the manufacturer, especially since it is not a part that can be repaired. The cost of the original double mass is up to several thousand zlotys. However, when deciding to replace it, it is better to invest in components from reputable manufacturers, because the quality of the dual mass flywheel depends on the length of its use, as well as the service life of the gearbox. Better-quality parts also mean fewer visits to mechanical plants. For many car models, especially those longer available on the market, you can buy replacements for dual mass wheels, but they are only slightly cheaper than the originals. However, getting replacements for new car models can be much more difficult. Some customers may choose to buy a much cheaper used dual mass wheel, but this is the most risky option as you cannot be sure about the actual condition of the part.

Or maybe regeneration?

An alternative to replacing the dual mass flywheel can be its regeneration. This service is offered by mechanical plants specializing exclusively in the regeneration of dual mass wheels and their clutches. Only original dual masses or high-quality replacements can be regenerated. During the service, damaged elements inside the wheel are replaced. It is worth noting that the service center uses high-quality parts for these repairs, because only such parts can be ensured by the long use of the wheel. All abrasive surfaces of the mass flywheel are also ground. Finally, the wheel is balanced to ensure proper, stable operation. Often you can buy a wheel after regeneration, and some services even give a one-year or two-year warranty for this part.

Labour cost

Labor in the case of replacing a dual-mass wheel is an expense from about a few hundred to even a thousand zlotys, depending on the car model and the amount of work. You can also try to replace this part yourself, but sometimes the procedure requires removing the engine from the car. In addition, users with experience in vehicle mechanics should decide on their own replacement, others will do better by giving the car to a specialist garage.

Tips
Motorhome accident repairs
When we have a motorhome with a minor or larger accident, or we intend to buy a collision car, it is always worth contacting a proven service, specialized in repairing motorhomes. The Elcamp company from Krakow, known as a manufacturer and seller of motorhomes and a distributor of car parts and accessories, also runs a camping car repair service. Not only what's outside Most often, during a collision, elements of the outer skin of the car are damaged. The effects, however, can be much more serious. It is always worth checking if the equipment inside the vehicle and installations: water, gas, electricity, TV and others have not been damaged. The next stage of repair is the replacement of damaged parts . It is safest to get a specific, new part directly from the manufacturer. Elcamp gives a guarantee for all work performed, unless the repair at the customer's request was not carried out in accordance with the recommended technology. Then no one will take responsibility for any future faults. The biggest enemy of any building is its leakage . The vast majority of motorhomes have "sandwich" coverings. After a collision, check if there are any leaks through which water enters the interior, causing the frame to rot. In the event of damage or leakage of the roof, we will usually have nothing else to do but replace it with a brand new one. This usually takes a lot of time and money. Is the repair worth it? In the autumn and winter period, the workshop is working at full speed. A company with as much experience as Elcamp undertakes every repair of a damaged vehicle . Clients usually ask two questions: about the cost and duration of the work. Unfortunately, post-accident repair can take up to several months . This is due to the fact that not all parts are available "out of stock". The cost obviously depends on the degree of damage to the vehicle or its equipment. When the initial cost , which is usually estimated at the first inspection, exceeds the value of the car, it makes no sense to undertake repairs. Repair expenses are, of course, a river topic. They can be up to 100% of the market value of the vehicle. It is worth emphasizing, however, that it is not synonymous with the actual selling price - well-kept cars, repaired with the use of original parts, reach prices above average market prices. Please check before buying Sometimes it's a good idea to buy a used vehicle. However, be careful with new (or almost new) cars at bargain prices . Then we can almost be sure that they have had an accident. Of course, you can do something with them, but it is important to know about a possible collision. The purchase of an accident motorhome can even be profitable, provided that the vehicle is thoroughly inspected and, during the inspection, as much damage as possible related to the incident (or even earlier) is noticed. It even happens that the cost of post-accident work is lower than in the case of non-damage repair. Remember that previous defects are easy to hide in a damaged car, in which the seller will not allow us to connect, for example, electricity or gas during the inspection, explaining that the installations may be out of order. Sometimes it is of course true, but in this way we are deprived of the possibility of checking individual pieces of equipment. Haste is a bad advisor To find a used motorhome in good condition, you need to spend some time searching for it. It is rare that the first copy that catches our eye is actually worth buying. Here there is a small problem - buying a car abroad. Since we are going far and spending money to see the car, even if it does not correspond to the description, we often decide to buy it anyway. This is a serious mistake. When we are not specialists ourselves, it is best to opt for an advisor - it is an expense much lower than the unexpected repair later. Elcamp's experts often advise on the purchase of damaged or used cars, both at the company's headquarters and at the seller, at the request of customers. However, as they say themselves, nothing can replace a car inspection in a professional service prepared for the comprehensive service of camping vehicles, which has all the necessary equipment. Thanks to them, it is possible to detect defects that even an experienced specialist will not notice with the naked eye.
