By the end, you’ll have a working mower and a renewed sense of confidence in your DIY skills.
Identifying the Right Parts
Before embarking on your repair journey, it’s crucial to identify the correct replacement parts for your Husqvarna lawn mower. While the process is generally similar for most models, variations do exist, so accurate identification is essential.
1. Locate Your Mower’s Model Number
The first step is to locate your mower’s model number. This vital information is typically found on a sticker attached to the mower deck, often near the engine. It may also be on the side of the mower, or even on the packaging if you still have it. The model number will be a combination of letters and numbers, such as “122LC” or “725AWD.”
2. Finding the Right Pull Cord
Once you have your model number, you can easily find the correct replacement pull cord online or at a local hardware store. Simply search for “Husqvarna pull cord” followed by your mower’s model number. Pay close attention to compatibility, as different models may require specific lengths or attachment styles.
3. Additional Parts
While the pull cord is the primary component, you may need additional parts depending on the severity of the damage. These might include:
- Recoil Spring: This spring is responsible for retracting the cord. If it’s worn or broken, it should also be replaced.
- Pull Starter Housing: The housing holds the entire assembly together. If it’s cracked or damaged, you may need a new one.
Disassembling the Pull Starter Assembly
Now that you have the necessary parts, it’s time to disassemble the pull starter assembly. This process involves removing the old cord and preparing the housing for the new one.
1. Prepare Your Work Area
Find a clean and well-lit space to work. You’ll need a few basic tools, including:
- Screwdriver: A Phillips head screwdriver is typically used to remove the screws on the pull starter housing.
- Wrench: You may need a wrench to loosen or tighten nuts on the housing.
- Gloves: Wear gloves to protect your hands from sharp edges or dirt.
2. Remove the Outer Housing
Locate the pull starter assembly on your mower. It’s usually located near the engine, with the cord attached to the handle. Carefully remove the screws holding the outer housing together. You may need to use a wrench to hold the housing while removing the screws.
3. Disconnect the Old Cord
Once the housing is removed, carefully disconnect the old pull cord. It may be connected to the recoil spring or a small hook inside the housing. Be cautious when disconnecting the cord, as it can be under tension.
4. Inspect the Recoil Spring
While the housing is open, take a moment to inspect the recoil spring. If it’s worn, stretched, or broken, it’s a good time to replace it. A faulty spring can prevent the cord from retracting properly, making starting the mower difficult.
Installing the New Pull Cord
With the old cord removed and the housing prepared, you’re ready to install the new one. The installation process is essentially the reverse of disassembly.
1. Connect the New Cord
Attach the new pull cord to the recoil spring or the hook inside the housing. Ensure the cord is secured properly, preventing it from slipping or detaching.
2. Reassemble the Housing
Carefully reassemble the outer housing, ensuring that all screws are securely tightened. Don’t overtighten, as this can damage the housing.
3. Test the New Cord
Before starting your mower, test the new pull cord to ensure it’s working properly. Pull the cord a few times, checking for smooth operation and a proper retraction.
Troubleshooting Common Issues
Even after successfully replacing the pull cord, you may encounter some challenges. Here’s how to address some common issues:
1. Cord Not Retracting
If the cord doesn’t retract properly, the recoil spring may be faulty or not installed correctly. Double-check the spring installation, ensuring it’s properly attached to both the cord and the housing. If the spring is damaged, replace it with a new one.
2. Cord Snapping Back Too Hard
If the cord snaps back too forcefully, the recoil spring may be too strong or not properly adjusted. Consider adjusting the spring tension or replacing it with a lighter spring if necessary.
3. Cord Not Engaging the Engine
If the cord isn’t engaging the engine, the problem might lie in the starter mechanism itself. Check the starter pawl, which is responsible for engaging the engine. It may be worn or broken, requiring replacement.
Tips for Success
Here are some helpful tips to ensure a smooth replacement process:
- Take Photos: Before disassembling the pull starter, take pictures of the process. This will help you remember the order of components and ensure proper reassembly.
- Label Wires: If there are any wires connected to the pull starter, label them to avoid confusion during reassembly.
- Use a Torque Wrench: A torque wrench can help prevent overtightening the screws, ensuring proper assembly and preventing damage to the housing.
Conclusion
Replacing a broken pull cord on your Husqvarna lawn mower is a straightforward task that can save you time and money. By following the steps outlined in this guide, you can confidently tackle this repair yourself and get your mower back in action. Remember to use caution when working with tools and ensure that all parts are securely installed before operating the mower. With a little effort and the right parts, you’ll be enjoying a perfectly functioning lawn mower in no time.
FAQ
1. Why does my Husqvarna lawn mower pull cord break?
A broken pull cord on a Husqvarna lawn mower is typically a result of wear and tear. The cord is constantly being pulled and stretched, and over time it can weaken and eventually snap. Additionally, improper use or a faulty recoil spring can also contribute to a broken pull cord.
To avoid this, it’s important to use the pull cord gently and not yank on it excessively. It’s also a good idea to periodically inspect the cord for signs of wear and replace it before it breaks completely.
2. What tools do I need to replace the pull cord?
To replace the pull cord on your Husqvarna lawn mower, you’ll need a few basic tools. These include a flat-head screwdriver, a Phillips-head screwdriver, and a pair of pliers.
You may also need a replacement pull cord, which can be purchased from a local hardware store or online retailer. Make sure to get a cord specifically designed for your model of Husqvarna lawn mower.
3. How do I remove the old pull cord?
First, disconnect the spark plug wire to prevent accidental starting. Then, remove the cover that protects the pull cord mechanism. This is usually secured with a few screws. Once the cover is off, you’ll see the old pull cord attached to the recoil spring.
Carefully detach the old pull cord from the recoil spring. You may need to use pliers to help loosen it. The cord is usually attached to the recoil spring with a small metal clip.
4. How do I attach the new pull cord?
Before attaching the new pull cord, it’s crucial to make sure the recoil spring is properly engaged. This ensures the spring functions correctly and pulls the cord back after each use.
Once the spring is ready, thread the new pull cord through the hole in the recoil spring. Make sure the cord is fully inserted and securely attached to the spring. You can secure the new cord using the same metal clip that held the old cord.
5. How do I adjust the pull cord tension?
The pull cord tension needs to be just right. Too much tension makes starting the engine difficult, while too little tension can lead to the cord slipping.
To adjust the tension, you’ll need to loosen or tighten the nut on the recoil spring. Start by adjusting the tension slightly and then test the pull cord. If it feels too tight or too loose, adjust it again until you find the right tension.
6. How do I reassemble the lawn mower?
Once you’ve successfully replaced the pull cord, reassemble the lawn mower. Replace the cover that protects the pull cord mechanism, making sure to tighten all the screws securely.
Before starting the engine, reconnect the spark plug wire. Then, test the pull cord to ensure it’s functioning properly. If it feels smooth and pulls back consistently, you’ve successfully replaced the pull cord.
7. Can I replace the pull cord myself, or should I take it to a mechanic?
Replacing a pull cord on a Husqvarna lawn mower is a relatively simple task that most DIYers can handle. However, if you’re not comfortable working with mechanical equipment or if your lawn mower is particularly complex, it’s best to take it to a qualified mechanic.
They have the expertise and tools to properly replace the pull cord and ensure it’s functioning correctly. Additionally, a mechanic can identify any other potential problems with your lawn mower and address them while they’re working on it.
