The roar of your lawn mower suddenly gives way to a disheartening silence. You pull the cord, but it feels limp, offering no resistance. Your lawn mowing day is interrupted by a broken pull cord. Fear not, replacing a pull cord is a relatively simple task that can be done with basic tools and a little patience. This guide will walk you through the process, explaining everything from identifying the right cord to successfully installing it.
In essence, replacing a broken pull cord involves removing the old one, installing the new one, and ensuring proper tension. This article will detail each step, providing clear instructions and helpful tips to ensure a smooth and successful repair.
Identifying the Right Pull Cord
Before you head to the store, it’s crucial to understand what you’re looking for. The wrong pull cord could lead to compatibility issues and prevent your mower from starting.
Understanding the Components
The pull cord assembly consists of a few key components:
- The Cord: This is the part you pull to start the engine. It’s typically made of nylon or rope.
- The Handle: This is the part you grip while pulling the cord. It often features a built-in recoil spring.
- The Recoil Spring: This spring housed within the handle provides the force needed to retract the cord after it’s pulled.
- The Starter Pawl: This small metal part engages with the flywheel to rotate the engine. It’s typically located on the end of the cord.
Matching the Cord to Your Mower
To ensure the new cord works correctly, you need to find a replacement that matches the following:
- Length: Measure the length of the old cord from the tip of the handle to the starter pawl.
- Diameter: Measure the diameter of the old cord using a ruler or calipers.
- Starter Pawl: Ensure the new cord has the correct type of starter pawl that matches your mower.
Where to Buy a New Cord
You can find replacement pull cords at most hardware stores, lawn mower repair shops, and online retailers.
Disassembling the Old Pull Cord
Once you have the new cord, it’s time to remove the old one. This process may vary slightly depending on your specific mower model.
Step 1: Locate the Pull Cord Assembly
The pull cord assembly is usually located on the side of the mower engine, often near the air filter. It’s typically housed in a black plastic or metal housing.
Step 2: Disconnect the Pull Cord
If your mower uses a spring-loaded design, the pull cord might be held in place by a spring clip. Release this clip by gently pressing down on the lever or pin.
Step 3: Remove the Pull Cord Assembly
Once the cord is disconnected, you’ll likely need to unscrew the entire pull cord assembly from the engine housing. This is usually done with a socket wrench. Be careful not to lose any small parts like screws or springs.
Step 4: Inspect the Recoil Spring
While the assembly is removed, take a moment to inspect the recoil spring. If it’s weak or broken, it’s best to replace it along with the cord.
Installing the New Pull Cord
Now that the old cord is out, it’s time to install the new one.
Step 1: Connect the New Pull Cord
Attach the new pull cord to the engine housing. If your mower uses a spring-loaded design, you’ll need to feed the new cord through the appropriate slot or guide on the engine housing. Make sure the starter pawl on the end of the new cord properly engages with the flywheel.
Step 2: Secure the Pull Cord Assembly
Carefully reattach the pull cord assembly to the engine housing, ensuring the screws are tightened securely. If you’ve replaced the recoil spring, make sure it’s properly installed and that the spring tension is correct.
Step 3: Test the Pull Cord
Before starting the mower, pull the cord a few times to make sure it retracts smoothly and that the starter pawl engages properly with the flywheel.
Troubleshooting Common Issues
While replacing a pull cord is generally straightforward, some problems can arise.
The Pull Cord is Too Tight
If the pull cord feels too tight, it’s likely the recoil spring is too strong. You may need to adjust the spring tension by loosening the spring’s retaining nut.
The Pull Cord is Too Loose
If the pull cord feels too loose, the recoil spring might be worn out. You may need to replace the spring with a new one.
The Starter Pawl Isn’t Engaging
If the starter pawl isn’t engaging with the flywheel, the problem could be with the pawl itself or the flywheel. Inspect both components and replace them if necessary.
Maintaining Your Lawn Mower’s Pull Cord
To prevent future pull cord problems, it’s essential to maintain your lawn mower properly.
Regular Cleaning and Inspection
- Clean: Keep the pull cord assembly clean and free of debris.
- Inspect: Regularly inspect the pull cord for signs of wear or damage.
- Lubricate: Periodically lubricate the moving parts of the pull cord assembly with a light oil.
Proper Storage
When storing your lawn mower for extended periods, make sure it’s clean and dry.
Don’t Overtighten the Pull Cord
Avoid overtightening the pull cord as this can strain the recoil spring.
