However, not everyone owns an impact wrench or has access to one. In this blog post, we will discuss how to remove flywheel nut without impact wrench.

Can You Remove the Flywheel Nut Without An Impact Wrench?

Removing a flywheel nut can be daunting, especially if you don’t have a specialized tool like an impact wrench. But fear not, there are alternative methods that can help you get the job done.

One option is to use a breaker bar, which can provide greater leverage and torque than a regular socket wrench. Another approach involves heating the nut with a propane torch or applying penetrating oil to help loosen the grip.

While these methods may require a little more effort and patience, they can ultimately save you from buying an expensive impact wrench or paying for professional help. So, yes, you can remove the flywheel nut without an impact wrench, all it takes is a little ingenuity and the right tools.

Why Should You Remove the Flywheel Nut Without An Impact Wrench?

Removing the flywheel nut is a common task for those who work with engines. While many opt to use an impact wrench, there are good reasons to consider removing the nut manually. First and foremost, using an impact wrench can cause damage to the flywheel itself. Additionally, the high torque of the impact wrench can strip the threads, making it difficult to reattach the nut properly.

By removing the flywheel nut by hand, you can ensure that the flywheel remains undamaged and that the nut is properly secured in place when you reattach it. It may take a little more time and effort, but the peace of mind that comes with knowing you’ve done the job right is well worth it.

7 Ways to Follow on How to Remove Flywheel Nut Without Impact Wrench

1. Use a Breaker Bar and Socket

One of the easiest ways to remove a flywheel nut without an impact wrench is by using a breaker bar and socket. A breaker bar is a type of bar that has a swivel joint on one end, which lets it angle and rotate in different directions.

Using a Breaker Bar and Socket

Place the socket on the nut to remove the nut, then attach the breaker bar. Apply force to the breaker bar, rotating clockwise or counterclockwise until the nut comes off. You may need to use some penetrating oil if the nut is stuck.

2. Use a Cheater Bar

If the breaker bar doesn’t have enough leverage, you can always add an extension or a “cheater bar.” Cheater bars are long pipes placed over the breaker bar, giving it extra length. To use it, attach it to the breaker bar and apply some force. However, be careful not to use too much force so that you can snap the breaker bar or cheater bar in half.

3. Use a Vise Grip

A vise grip is a clamping device used to hold things tightly. To use a vise grip, attach it to the nut, lock it in place, and turn the nut in either direction. One disadvantage of this method is that it may damage the nut’s threads, so use it only as a last resort.

4. Use a Manual Impact Driver

A manual impact driver is a tool that you can use to apply torque to a fastener without using an impact wrench. To use it, you’ll need to attach the appropriate size bit or socket to the driver, place it on the nut, and turn the driver counterclockwise, delivering shock waves that break stuck threads free.

5. Use Heat

Heating the nut can help expand the metal, making removing it easier. However, be careful not to heat the nut too much, as it can damage other parts of the engine. This method uses a propane torch or a heat gun to heat the nut for a few minutes, then use a wrench or socket to turn the nut.

6. Use Water

If the nut is stuck due to rust, you can use water to help loosen it up. Wet the nut down with tap water and let it sit for a few minutes. This will allow the moisture to penetrate the threads and help loosen them up. Once it’s soaked, you can use a wrench or socket to turn the nut.

7. Use Penetrating Oil

Penetrating oil is an ideal choice for removing stuck nuts and bolts. To use it, apply some of the oil onto the nut and let it sit for 10-20 minutes, allowing the oil to penetrate the threads and help loosen them up. After that, use a wrench or socket to turn the nut. If this doesn’t work, you may need a stronger penetrating oil such as WD-40.

That’s it! You’ve now learned how to remove flywheel nut without impact wrench. With the right tools and techniques, it’s not too difficult of a job. Good luck!

5 Considerations Things When You Need to Remove Flywheel Nut Without Impact Wrench

1. The Type of Car You Have

Different Cars Have Different Types of Flywheels

The first consideration is the type of car you have. Different cars have different types of flywheels, and some are easier to remove than others. If you have a car with a standard transmission, the flywheel will be easier to remove than an automatic one.

2. The Size of the Nut

The second consideration is the size of the nut. The nut that holds the flywheel in place is usually very large, and it can be difficult to remove without an impact wrench. If you do not have an impact wrench, you may need to borrow one from a friend or neighbor.

3. The Condition of the Nut

The third consideration is the condition of the nut. If the nut is rusty or damaged, removing it may be difficult without an impact wrench. In this case, taking the car to a mechanic and having them remove the flywheel for you is best.

4. The Location of the Nut

The fourth consideration is the location of the nut. The nut is located on the back side of the engine, and it can be difficult to reach without an impact wrench. If you cannot reach the nut, you may need to take the car to a mechanic and have them remove the flywheel.

5. The Cost of Replacing the Flywheel

The fifth consideration is the cost of replacing the flywheel. You must purchase a new one if you damage the flywheel during removal. Flywheels can be expensive, so it is important to be careful when removing them.

Benefits of Remove Flywheel Nut Without Impact Wrench

There are a few reasons why removing a flywheel nut without an impact wrench can be beneficial. First, using a manual wrench allows for more control and precision during removal.

Using a Manual Wrench Allows for More Control

This can be particularly important when working with fragile or sensitive equipment. Additionally, manual tools are often more readily available than power tools, making the process more accessible, especially if you work in a remote location or have limited resources.

Another benefit of using a manual wrench is that it can help you develop important skills and techniques for various mechanical tasks. Finally, removing a flywheel nut by hand can be a satisfying and rewarding experience as you watch your efforts pay off as a successfully removed part.

4 Common Mistakes People Make When Trying to Remove Flywheel Nut Without Impact Wrench

1. Not Removing the Brake Caliper

One of the most common mistakes people make when removing a flywheel nut is forgetting to remove the brake caliper first. The brake caliper is located on the front of the engine and is held in place by two bolts. These bolts must be removed before the brake caliper can be lifted off the rotor. Failure to do this will damage the brake caliper when the flywheel is removed.

2. Not Using an Impact Wrench

Another common mistake is not using an impact wrench to remove the flywheel nut. An impact wrench is a power tool that uses hammering to loosen and remove nuts and bolts. Removing a flywheel nut with an impact wrench is much easier than removing a regular wrench.

3. Not Locking the Flywheel

Forgetting to Lock the Flywheel

Another mistake people make is forgetting to lock the flywheel before attempting to remove the nut. The flywheel is what the engine’s crankshaft attaches to, and it can be very difficult to remove the nut if the flywheel is not locked in place. There are several ways to lock a flywheel, but one of the easiest is using a rope or bungee cord. Simply wrap the rope or cord around the circumference of the flywheel and then pull tight. This will keep the flywheel from turning while you’re removing the nut.

4. Stripping the Nut

One final mistake people make when removing a flywheel nut is stripping it. This occurs when too much force is applied to the nut, and it begins to strip or damage the threads. When this happens, it becomes very difficult (if not impossible) to remove the nut without damaging it further. To avoid stripping the nut, use an impact wrench and apply only as much force as necessary.


Removing a flywheel nut without an impact wrench is possible but requires patience and attention. Using a breaker bar and socket, cheater bar, a vise grip, manual impact driver, and heat are some of the methods you can use.

Remember to be gentle and careful when removing the nut to prevent damage to other engine parts. With the right tools and techniques, you can successfully remove the nut and carry on with your engine repair. Thanks for reading our post about how to remove flywheel nut without impact wrench.
