Understanding the Problem: Why is My Pull Cord Not Working?
A broken pull cord is often the result of wear and tear. Repeated use can cause the cord to fray, snap, or become disconnected from the engine. Here are some common reasons why your pull cord might be giving you trouble:
- Frayed or Broken Cord: Over time, the cord can become weakened and eventually break. This is especially common with older lawnmowers.
- Disconnection from the Engine: The cord may have become detached from the engine’s recoil starter.
- Worn Recoil Spring: The spring within the recoil starter can weaken over time, causing the cord to feel sluggish or not engage the engine properly.
- Damaged Recoil Starter: The plastic housing of the recoil starter can crack or break, preventing the cord from working correctly.
Essential Tools and Materials for Repair
Before you start, ensure you have these tools and materials on hand:
- Screwdriver (Phillips and flathead): To remove screws from the recoil starter housing.
- Pliers: To help with removing and installing the pull cord.
- Replacement Pull Cord: Purchase a new cord that matches your lawnmower model.
- Safety Glasses: To protect your eyes during the repair process.
- Gloves: To protect your hands from sharp edges or grease.
Step-by-Step Guide: Repairing Your Lawn Mower Pull Cord
Follow these steps carefully to replace your lawnmower pull cord:
1. Disconnecting the Spark Plug:
- Safety First: Always disconnect the spark plug wire before working on any part of the engine. This will prevent accidental starting.
2. Accessing the Recoil Starter:
- Locate the Recoil Housing: The recoil starter is typically located on top of the engine, with the pull cord extending from it.
- Remove Screws: Using the appropriate screwdriver, remove the screws holding the recoil starter housing in place.
3. Inspecting the Recoil Starter:
- Examine the Cord: Check the condition of the old cord. Is it frayed, broken, or simply disconnected?
- Inspect the Spring: Carefully observe the recoil spring. Is it worn or broken?
- Check the Housing: Look for any cracks or damage to the recoil starter housing.
4. Replacing the Pull Cord:
- Remove the Old Cord: Use pliers to carefully remove the old cord from the recoil starter.
- Install the New Cord: Thread the new pull cord through the recoil starter housing, following the manufacturer’s instructions. Secure the cord by threading it through any designated slots or clips.
5. Replacing the Recoil Spring (Optional):
- If Necessary: If the spring is damaged or worn, replace it with a new one. This will ensure proper engine starting.
6. Reassembling the Recoil Starter:
- Secure the Housing: Once the new cord is in place, carefully put the recoil starter housing back together and tighten the screws.
7. Reconnecting the Spark Plug:
- Safety First: Reconnect the spark plug wire.
8. Testing the Repair:
- Start the Engine: Try to start the lawnmower. The pull cord should retract smoothly and engage the engine properly.
Troubleshooting Tips
If your pull cord repair isn’t working as expected, here are some additional troubleshooting tips:
- Check the Cord Routing: Ensure the new cord is properly routed through the recoil starter housing and not getting caught on anything.
- Examine the Spring Tension: If the spring feels weak, it might need to be replaced.
- Inspect the Engine: If the engine still won’t start, there might be an issue with the engine itself, such as a clogged carburetor or a spark plug issue.
Maintaining Your Lawn Mower Pull Cord
To extend the life of your lawnmower pull cord, follow these maintenance tips:
- Regularly Clean the Recoil Starter: Remove any debris or grass clippings that may have accumulated around the recoil starter housing.
- Lubricate the Recoil Spring: Apply a light oil to the spring periodically to prevent corrosion and maintain smooth operation.
- Store Properly: When not in use, store your lawnmower in a dry place to prevent moisture damage to the pull cord and other components.
Conclusion
Repairing a broken lawnmower pull cord is a relatively simple task that can be done by most homeowners. By following the steps outlined in this guide, you can get your machine running smoothly again in no time. Remember to always prioritize safety and take your time during the repair process.
FAQ
Q1: Why is my lawn mower pull cord so hard to pull?
A: A stiff pull cord can be caused by a few things. One common issue is a worn-out recoil spring. This spring is responsible for retracting the cord, and over time it can lose its tension, making the pull harder. Another culprit could be friction in the recoil housing. Dirt, debris, or even a build-up of old lubricant can cause the moving parts to bind, making the pull difficult. Lastly, a tangled or knotted pull rope can also create resistance and make it harder to pull the cord.
Q2: My lawn mower pull cord won’t retract. What’s going on?
A: A pull cord that won’t retract is often a sign of a broken or worn-out recoil spring. This spring is vital for retracting the cord after each pull, and when it fails, the cord gets stuck in the extended position. You may also be dealing with a broken or jammed pull rope. The rope can become frayed or tangled, preventing it from retracting properly. In some cases, the issue could be a stuck or damaged recoil housing, preventing the cord from moving freely.
Q3: How do I replace the recoil spring on my lawn mower?
A: Replacing the recoil spring is a relatively straightforward process. Start by removing the pull cord housing cover, which is usually held in place by screws or clips. Carefully remove the old spring, noting its position and how it connects to the housing. Install the new spring in the same location, ensuring it is properly seated and connected. Reassemble the housing cover and test the pull cord to ensure it retracts smoothly.
Q4: Can I lubricate my lawn mower pull cord to make it easier to pull?
A: While it may seem like a good idea, lubricating the pull cord is generally not recommended. Most pull cords are made of nylon or other materials that can become brittle or weakened with excessive lubrication. This can actually lead to the cord fraying or breaking prematurely. If you’re experiencing friction in the recoil housing, it’s best to clean and inspect the mechanism instead of using lubricant.
Q5: How often should I replace my lawn mower pull cord?
A: The lifespan of a pull cord can vary depending on the quality of the cord and how often the mower is used. Generally, a pull cord should last for several years before needing replacement. However, if you notice signs of wear and tear, such as fraying, cracking, or difficulty retracting, it’s best to replace it sooner rather than later.
Q6: What are the symptoms of a broken lawn mower pull cord?
A: A broken pull cord will exhibit several distinct symptoms. The most obvious is that the cord will simply break, leaving a frayed or cut end. You may also notice that the cord doesn’t retract properly, or that it gets stuck in the extended position. In some cases, the cord may even be completely missing from the housing.
Q7: Is it safe to continue using a lawn mower with a broken pull cord?
A: No, it’s not safe to continue using a lawn mower with a broken pull cord. This could lead to serious injury. The pull cord is vital for starting the engine and provides a safe way to disconnect the engine if needed. Without a functional pull cord, you risk losing control of the mower or being unable to stop it if necessary. Replacing a broken pull cord is a simple and relatively inexpensive repair, so it’s important to address this issue as soon as possible.
