What is a Dirt Bike Flywheel?
A dirt bike flywheel is a circular or ring-like heavy metal component on the crankshaft behind the engine’s primary cover. It helps to run the bike’s engine smoothly. When the engine starts, the flywheel stores its energy in its rotation and then releases it as needed to keep it running smoothly. It helps out the power delivery and prevents the engine from stalling.
So a flywheel serves essential functions such as:
- Storing rotational energy
- Aiding ignition timing
- Balancing engine components
- Accommodating a starter mechanism.
Flywheel removal is necessary to access the internal engine parts of a dirt bike. At the same time, specialized tools like pullers are commonly used, and alternative methods can be applied cautiously when a puller is unavailable.

- Resourcefulness: Some enthusiasts enjoy finding innovative ways to solve mechanical challenges. Removing a flywheel without a puller can test skills and resourcefulness.
- Limited Access: On occasions when you can’t easily access a flywheel’s mounting area due to design constraints, you might need to explore unconventional removal methods.
It’s important to note that removing a flywheel without a puller can be risky. The flywheel is a delicate component, and improper removal methods could cause damage to the flywheel, the crankshaft, or other engine parts. Using the appropriate tools and techniques recommended by the manufacturer or a mechanic is the safest way.
Tools Required to Remove Flywheel Without Puller
To remove a dirt bike flywheel without a puller, consider using the following:
- Rubber mallet
- Wooden block and hammer
- Heat source (cautiously)
- Penetrating oil
- Hammer and screwdriver
- Pry bar or lever
- A socket wrench
- A C-clamp
Step-by-Step Guide on How to Remove Dirt Bike Flywheel Without Puller
Here’s a step-by-step guide on how to remove a dirt bike flywheel without using a puller:
1. Disconnect Ignition Components
Firstly, disconnect the spark plug wire and the negative battery cable to prevent accidental engine firing during removal.
2. Cool Down Bikes’ Engine
If you’ve been riding till now, your engine can be hot. Removing the flywheel without a puller with a hot-engine bike can be difficult. So, please turn it off and let it sit idle for at least 30 minutes to cool down your engine.
3. Loosen the Flywheel Nut
The flywheel nut is located on the back of the flywheel that secures the flywheel onto the crankshaft taper. It’ll be tightened with a large socket wrench. Use a breaker bar, wrench, socket, or spanner to loosen the nut. Moreover, applying penetrating oil would be best if the nut is stubborn due to rust or corrosion. And continue turning the nut until it’s loose enough to remove by hand.
4. Remove the Flywheel
When the engine is cooled down, and the flywheel nut is loosened, you can easily remove the flywheel without any puller. Place the C-clamp on the flywheel and tighten it until the flywheel is loose.
Now remove the cap on the end of the crankshaft first—generally, 3 or 4 bolts holding the flywheel in its place. There may be two small holes in the flywheel when the cap is removed. The holes are located near the edge of the flywheel.
Use a screwdriver or punch to drive two screws into these holes. Be cautious so that it’ll not damage the threads on the crankshaft. Now you can pull the flywheel off the end of the crankshaft.
5. Inspect the Flywheel
Once the flywheel is removed, it’s time to inspect the flywheel, crankshaft, and surrounding components for any damage. If you’ve observed any cracks or signs of damage in the flywheel, it’ll need to be replaced. But if the flywheel is good, you should clean it and use it again.
You can clean the flywheel using a brush or sandpaper to remove rust or debris on the surface.
6. Inspect the Clutch Assembly
After removing the flywheel:
- Inspect the clutch components for wear, damage, and proper function.
- Check clutch plates, springs, pressure plates, and clutch basket for signs of wear, flatness, or oil contamination.
- Replace worn parts and ensure smooth operation before reassembly.
It helps maintain an efficient clutch system for optimal dirt bike performance.
7. Reinstall the Flywheel
That’s your flywheel tidied; you can reinstall it on the crankshaft again. Align the holes in the flywheel with those in the crankshaft.
Tighten the nut or screws until they are snug. Be careful not to overtighten them, as it can damage the threads on the crankshaft. Once the flywheel is secure, you can install the clutch assembly and reassemble the engine.
That’s it! You’ve now learned to remove the dirt bike flywheel without a puller. This method is quick and easy and doesn’t require any special tools. You can save time and money by doing it with patience. Thanks for reading!
A heavier flywheel will provide smoother power delivery and more torque, helping to climb hills and ride in rough terrain. However, a heavier flywheel will make the engine harder to start and accelerate.
Consider Some Safety Precautions
There are things to keep in mind in removing a flywheel:
- Wear safety gear: Gloves and eye protection.
- Allow the engine to cool down.
- Secure the bike on a stable surface.
- Disconnect the spark plug.
- Use gradual force, and avoid sudden movements.
- Choose the correct tools for each step.
- Keep hands away from moving parts.
- Prevent engine movement.
- Work in a well-lit area.
- Follow manufacturer guidelines.
- Regularly inspect components for damage.
- If you need more clarification, seek professional help.
