What Causes Flywheel Damage?

The flywheel is an important part of the engine, but if it goes wrong, it can cause a lot of trouble for the user's driving experience. So, what causes damage to the flywheel of an engine? More importantly, how much does it cost to replace the flywheel of an engine? In this article, we'll take you through the common causes of flywheel damage and how to spot the problem to avoid higher repair costs. Whether it's a strange burning smell, difficulty shifting gears, or a slipping clutch, all these symptoms signal flywheel failure. You can just read on to learn how to prevent and deal with these problems.

 

Causes of Damage to the Flywheel

Damage to the flywheel can occur for a variety of reasons, here are a few common ones:

1. Clutch wear or failure

Wear between the flywheel and the clutch is one of the main causes of flywheel damage. If the clutch is worn out, it creates excessive friction, leading to damage to the flywheel. In addition, it can lead to a burning odour emanating from underneath the car. This odour usually comes from the wear and tear of the clutch plates, which can be exacerbated by overheating of the flywheel.

 

2. Difficulty in shifting gears

When there is a problem with the flywheel, shifting gears usually becomes difficult. When you notice a sticking or resistance when shifting gears, this is an indication that the flywheel is in poor condition. Difficulty in shifting gears is a clear sign that the flywheel is damaged. In severe cases, it can lead to the user being unable to drive the construction machinery.

 

3. Gear slippage

If the engine speed increases faster than the actual driving speed of the construction machinery, this is the phenomenon of gear slippage. Slipping gears are usually caused by the flywheel not meshing properly with the clutch. This is caused by the flywheel warping or being covered with oil. If this occurs, it should be inspected and repaired as soon as possible.

 

4. Clutch vibration

If you feel vibrations when you depress the clutch pedal, or even if the floor of your construction machinery vibrates while you are driving, these are symptoms of a faulty flywheel. One of the functions of the flywheel is to absorb vibrations. When the flywheel is not working properly, it can trigger this abnormal vibration.

 

5. Engine vibration

An unbalanced flywheel can cause engine vibration. If you have recently replaced your flywheel or its associated parts, it is important to ensure that the bolts are tightened to the correct torque specification. The flywheel stores a lot of energy and a loose flywheel while driving can pose a serious safety hazard.

 

6. Improper clutch release

If you find that the clutch resistance is too high and the construction machinery struggles to start. This is also caused by the clutch not being able to disengage properly due to the warped flywheel.

 

7. Equipment stalls or starts with difficulty

The flywheel provides friction for the clutch and starter to achieve the starting of construction machinery from a standstill. If the momentum of the flywheel is not normal, the construction machinery may stall or have difficulty starting smoothly when starting. This is also a potential sign of flywheel damage.

 

How Much Does It Cost to Replace a Flywheel?

The cost of replacing a flywheel depends mainly on the price of the flywheel itself and the cost of labour.

1. Price of the flywheel itself

The price of the flywheel varies greatly from one piece of construction equipment to another. The price of a flywheel for an average model usually ranges from $80 to $500. Flywheels for high-performance, heavy-duty equipment can cost up to $800 or more. For example, MyMROmarts sells flywheels for different types of trucks, tractors, and other heavy equipment for between $80 and over $1,000. Specific aftermarket flywheel prices will vary depending on the brand and model of the applicable Cummins, Caterpillar, John Deere, Kubota, Bobcat, and more.

 

2. Labour cost

Replacing the flywheel requires dismantling the clutch and drivetrain, which has a high labour cost. Depending on the complexity of the repair and the location, it can be $120-$200 per hour. The job usually takes about 4 to 8 hours. All told the total cost of a flywheel replacement is $560 or more.

 

Flywheel damage stems from a variety of factors. Recognising the early signs of flywheel damage can help you deal with the problem on time. The cost of a flywheel replacement is more than $560, depending on the type of construction machinery and the complexity of the repair.
