To replace flywheel magnets, follow these steps:
1. Remove the flywheel cover using a screwdriver or socket wrench.
2. Locate the magnets on the flywheel. They are usually attached to the inner rim.
3. Use a magnet puller tool or a strong magnet to remove the old magnets from the flywheel. Apply steady pressure to pull them off.
4. Clean the flywheel surface and make sure it is free from any debris or adhesive residue.
5. Apply a small amount of adhesive to the back of the new magnets and carefully place them onto the flywheel, aligning them with the existing magnet pattern.
6. Allow the adhesive to dry completely before reinstalling the flywheel cover.
7. Test the flywheel to ensure the magnets are securely attached.
By following these steps, you can easily replace flywheel magnets and restore the proper functioning of your equipment.
If your small engine is having trouble starting or running properly, it may be due to a faulty flywheel magnet. The magnet generates an electric charge that sparks the plug in the engine’s ignition coil. Replacing the magnets is a specific process that requires careful attention to detail. However, with proper labeling and attention to magnet placement, you can replace them yourself without having to take the engine to a mechanic.
Step 1: Remove the Housing
Using a wrench of the appropriate size, remove the bolts that hold the pull start mechanism housing in place. Set the housing and bolts aside in a safe place to avoid losing any parts.
Step 2: Test and Mark the Magnets
Rotate the flywheel and test each magnet with a screwdriver. The magnet should be on the opposite side of the magneto, which is wrapped in wire and generates a charge when the magnets pass it. Label the magnet positions with masking tape, and label them as either R or A, depending on whether they are repelled or attracted to a small ceramic magnet.
Step 3: Remove the Magnets
Pry the magnets off the flywheel or unscrew the mounts depending on the flywheel’s configuration. Be sure to clean off any adhesive or debris left behind.
Step 4: Apply Adhesive
Follow the manufacturer’s instructions to apply a two-part epoxy or a strong adhesive like Gorilla Glue to the flywheel and/or magnet surfaces. Install the replacement magnets and allow the adhesive to cure completely.
Step 5: Replace the Housing
Reattach the pull start assembly housing with the original bolts.
FAQ
1. What is a flywheel in an engine?
A flywheel is a mechanical device that stores rotational energy in a rotating mass. It is typically connected to the engine’s crankshaft and helps to maintain smooth and consistent engine operation.
2. What are flywheel magnets?
Flywheel magnets are small magnets that are attached to the flywheel. They play a crucial role in generating electrical current in the engine’s ignition system. The movement of the magnets past the ignition coil induces voltage, which is then used to create a spark for combustion.
3. Why would I need to replace flywheel magnets?
Flywheel magnets can become damaged or weakened over time. This can lead to a loss of spark or inconsistent ignition, resulting in poor engine performance. Replacing the magnets is necessary to ensure proper functioning of the ignition system.
4. How can I tell if my flywheel magnets need to be replaced?
If you are experiencing ignition issues such as difficulty starting the engine, misfires, or a weak spark, it may indicate that the flywheel magnets are damaged or weakened. Additionally, visual inspection can reveal any cracks, chips, or missing magnets on the flywheel.
5. Can I replace the flywheel magnets myself?
Replacing flywheel magnets can be a complex task and requires some mechanical knowledge and experience. It involves removing the flywheel, carefully removing the old magnets, and installing new ones in their place. It is recommended to consult a professional or refer to the engine’s manual for specific instructions.
6. Where can I purchase replacement flywheel magnets?
You can purchase replacement flywheel magnets from various automotive and small engine parts stores. It is important to ensure that you get the correct magnets that are compatible with your specific engine model. Online retailers and authorized dealers are also good options for finding the right replacement parts.
7. Are there any preventive measures to prolong the lifespan of flywheel magnets?
To prolong the lifespan of flywheel magnets, it is important to regularly inspect and clean the flywheel, ensuring that it is free from dirt, debris, and metal shavings. Additionally, avoiding excessive heat or impact on the flywheel can help prevent damage to the magnets. Following proper maintenance procedures and using high-quality fuel and lubricants can also contribute to the longevity of the flywheel magnets.
