The flywheel is an essential component in heavy machinery and vehicles. It is responsible for storing and releasing energy to ensure smooth operation. However, even the sturdiest flywheels are not immune to damage, and when issues arise, they can disrupt the performance of the entire system. In this article, we’ll explore what causes flywheel damage, how it impacts your machinery, and the necessary steps to address the issue.
What Does a Flywheel Do?
When we talk about a flywheel, we usually refer to a heavy rotating wheel. In heavy equipment such as an excavator, the flywheel is part of the engine system. It is attached to the engine’s crankshaft, usually at the rear of the engine, where it plays a crucial role in stabilizing and regulating the engine’s power output. A flywheel stores rotational energy and helps balance the engine’s operation. Beyond this, flywheels assist in starting the engine, storing energy during deceleration, and redistributing it when acceleration resumes.
How Long Should a Flywheel Last?
Flywheels are designed for durability, often lasting between 100,000 to 150,000 miles in vehicles or several years in heavy machinery. However, wear and tear depending on usage, maintenance, and operating conditions. Frequent exposure to high temperatures, heavy loads, or poor maintenance can shorten its lifespan.
What Causes Flywheel Damage?
Flywheel damage can stem from several factors, including:
- Excessive Heat: Overheating due to excessive clutch use or poor lubrication can warp or crack the flywheel.
- Improper Installation: Misalignment during installation can lead to uneven wear and eventual failure.
- Worn Clutch Components: A worn or malfunctioning clutch can place extra stress on the flywheel, causing surface damage.
- Frequent Overloading: Operating machinery beyond its capacity increases pressure on the flywheel, leading to premature wear.
By understanding what causes flywheel damage, you can take preventive measures to extend a flywheel’s life and avoid costly repairs.
Can a Bad Flywheel Damage the Clutch?
Maybe you are still hesitant if you should keep your machinery running while you have already seen some flywheel damage. But the answer to the question is definitely a yes. A bad flywheel can significantly impact the clutch. When the flywheel surface becomes uneven or damaged, it can cause clutch slippage, overheating, or premature wear. This creates a chain reaction where the clutch components degrade faster, leading to reduced efficiency and costly repairs.
Can I Drive with a Bad Flywheel?
Driving with a bad flywheel is risky and can worsen the problem. A damaged flywheel can cause:
- Difficulty in shifting gears
- Increased vibrations
- Strange noises from the transmission
Operating machinery with these symptoms risks further damage to both the flywheel and the connected components. Immediate attention is recommended.
Can a Flywheel Be Repaired?
In some cases, a damaged flywheel can be resurfaced, a process where the flywheel’s surface is ground down to remove imperfections. However, resurfacing isn’t always feasible, especially for flywheels with severe cracks, warping, or heat damage. Replacement might be the safer and more cost-effective solution.
Is a Flywheel Expensive to Replace?
The cost to replace a flywheel can vary significantly depending on the type of machinery, the brand, and whether you’re using an OEM (Original Equipment Manufacturer) or aftermarket part. The average cost of an aftermarket flywheel ranges from $300–$1,000; the OEM ones usually take from $500–$2,000 or more. Also if you can’t replace it yourself, the labor cost is a considerable spend, too. Labor costs typically range from $500 to $1,500, depending on the complexity of the machinery and local labor rates.
If you have a low budget, you can consider purchasing an aftermarket option. High-quality aftermarket flywheels can be more affordable and also offer the best efficiency to your machinery.

Why Would You Need to Replace a Flywheel?
Flywheel replacement becomes necessary when:
- Cracks or severe warping are detected.
- Resurfacing is insufficient to restore functionality.
- The flywheel fails to provide adequate energy storage or transfer.
Ignoring these issues can lead to more extensive damage to the engine or transmission.
