This article will guide you through the simple process of replacing a lawn mower pull cord, empowering you to get back to mowing in no time. We’ll cover identifying the issue, gathering the necessary tools, and finally, replacing the cord itself with clear, step-by-step instructions. Let’s get started!
Overview: Replacing a lawn mower pull cord is a straightforward DIY repair that can save you time and money. It typically involves identifying the broken cord, purchasing a replacement, and then carefully detaching the old cord and attaching the new one.
Identifying the Problem
Before you begin, it’s crucial to confirm that a broken pull cord is indeed the source of your mower’s woes.
1. Inspect the cord: Look for signs of wear and tear, fraying, or a complete break in the cord.
2. Test the recoil system: If the cord is intact but not pulling back smoothly, the recoil spring might be faulty.
3. Check the engine: A broken pull cord could be a symptom of a larger engine problem, so ensure the engine isn’t seized.
If you’ve identified a broken cord as the issue, you’re ready to proceed with the replacement.
Gathering the Tools and Materials
To replace a pull cord, you’ll need a few basic tools, easily found in most garages:
- Replacement Pull Cord: This is the most important item. Ensure you get a cord specifically designed for your lawn mower model.
- Phillips Head Screwdriver: You’ll likely need this to remove screws securing the recoil housing.
- Pliers: Use these to help grip and pull the old cord.
- Safety Glasses: Protect your eyes from any potential debris.
- Work Gloves: Gloves offer protection while handling the cord and tools.
Once you have everything ready, you can begin the replacement process.
Replacing the Pull Cord: Step-by-Step
Now, let’s walk through the steps of replacing the pull cord:
1. Disconnect the Spark Plug: This crucial step ensures the engine won’t unexpectedly start during the repair. Locate the spark plug, which is usually located on the top of the engine, and disconnect the wire leading to it.
2. Remove the Recoil Housing: Locate the recoil housing, which is typically found on the side of the engine. Use your Phillips head screwdriver to remove the screws holding the housing in place.
3. Detach the Old Pull Cord: Once the housing is removed, you’ll see the old pull cord attached to the recoil spring. Carefully detach the old cord from the spring, using pliers if necessary.
4. Attach the New Pull Cord: Now, take your new pull cord and attach it to the recoil spring, following the same attachment points as the old cord. Ensure the cord is securely fastened to the spring.
5. Reassemble the Recoil Housing: Carefully place the recoil housing back onto the engine and tighten the screws you removed earlier.
6. Reconnect the Spark Plug: Now that the housing is back in place, reattach the spark plug wire to the spark plug.
7. Test the New Cord: Give the new pull cord a test pull. The cord should recoil smoothly, and the engine should start easily.
Troubleshooting and Tips
- Cord Length: If the new cord feels too short or long, adjust its length by carefully cutting the excess or adding a piece to the end.
- Recoil Spring: If the recoil spring is weak or broken, it’ll need to be replaced.
- Engine Problems: If the engine still doesn’t start after replacing the cord, you might have a larger engine issue that requires professional assistance.
Conclusion
Replacing a lawn mower pull cord is a relatively simple task that can save you time and money. By carefully following these steps, you can repair the cord, get your mower running again, and enjoy a smooth mowing experience. Remember to prioritize safety, use the appropriate tools, and inspect all components for any potential issues. If you’re unsure about any aspect of the process, seek advice from a qualified mechanic. And always remember, a well-maintained lawn mower ensures a well-maintained lawn!
FAQs
What tools do I need to replace a lawnmower pull cord?
You will need a few basic tools to replace your lawnmower pull cord. These include a screwdriver (usually a Phillips head), pliers, and possibly a small wrench or socket to loosen the recoil housing nut. You might also need a new pull cord, which is available at most hardware stores and online retailers. It’s a good idea to have a few spare parts on hand, including a spare pull cord, so you can replace it quickly and easily.
Having the right tools will make the process much easier. However, some mowers might require more specialized tools depending on the specific model and manufacturer. Always refer to the manufacturer’s instructions or a repair manual for your specific lawnmower model.
How do I know if my lawnmower pull cord needs replacing?
A broken or worn-out pull cord can cause several problems, including difficulty starting the mower, a slack pull cord, or a cord that breaks when you pull it. If you notice any of these symptoms, it’s time to replace your pull cord. You can also check the pull cord for fraying, cracking, or other signs of damage. A good visual inspection can help you determine if your lawnmower pull cord needs replacing.
While it may seem like a small issue, a damaged pull cord can lead to more serious problems. For example, a broken pull cord can damage the recoil assembly, making it harder to start the engine. It’s always better to replace a damaged pull cord as soon as possible to prevent further damage.
Can I use any pull cord for my lawnmower?
While most pull cords are compatible with different lawnmower models, it’s important to choose a cord specifically designed for your mower. Check the manufacturer’s website or contact them directly for the correct pull cord part number. Using a generic cord could be incompatible with the recoil assembly, potentially leading to problems with your lawnmower.
The length and material of the pull cord should be compatible with your lawnmower’s recoil assembly. The cord should be the right length to provide enough tension to start the engine effectively. Using an incorrect pull cord can damage the recoil assembly, leading to issues with starting your mower.
How do I measure the right length for the pull cord?
Measuring the length of your lawnmower pull cord is important to ensure a proper replacement. The length should be precise to ensure the cord works correctly. First, unhook the old pull cord from the recoil assembly. Then, extend the cord fully, measuring it from the hook at one end to the end of the cord. Write down the measurement, as it will be needed for the new pull cord.
Always double-check the measurement before purchasing a new pull cord. It’s best to measure the cord twice for accuracy. Using the wrong length pull cord can result in a loose or overly tight cord, making it difficult to start the mower.
How do I disconnect the old pull cord?
To disconnect the old pull cord, follow the instructions for your specific model. You’ll need to loosen the recoil housing nut, which secures the recoil assembly to the engine. Some lawnmower models may require the removal of the recoil housing cover. Once the nut is loosened, you can gently pull out the old pull cord.
Be careful when removing the old pull cord, as it may be attached to the spring inside the recoil assembly. If you encounter any resistance, consult your lawnmower’s manual or contact the manufacturer for guidance.
How do I attach the new pull cord?
To attach the new pull cord, thread it through the recoil assembly, following the same path as the old cord. Ensure the new pull cord is seated properly in the recoil housing and connected to the handle. The pull cord should be pulled through the recoil assembly with the same amount of tension as the old cord. This will ensure it is correctly secured and that it works properly.
After attaching the new pull cord, test it to make sure it operates smoothly and the mower starts easily. You may need to adjust the tension on the pull cord for optimal performance.
What else should I do after replacing the pull cord?
After replacing the pull cord, you should check for any other problems with the lawnmower. Make sure that the spark plug is clean and the air filter is not clogged. Also, check the engine oil level and make sure it’s full.
Take this opportunity to inspect the entire lawnmower for any potential issues, such as worn blades or loose bolts. By performing a routine inspection, you can identify and address any problems before they become bigger issues. This can help to keep your lawnmower running smoothly and efficiently for many years to come.
