This guide will walk you through the entire process, from identifying the problem to reassembling your mower, ensuring you’re back to mowing in no time.
In essence, replacing a broken pull cord involves removing the old cord, installing a new one, and then reconnecting it to the engine. This process may vary slightly depending on your mower model, but the basic steps remain the same. This article will guide you through the process, providing detailed instructions, helpful tips, and troubleshooting advice for a successful repair.
Identifying the Problem: When Your Pull Cord Needs Replacing
Before you dive into repairs, you need to confirm that the issue is indeed a broken pull cord. Here’s how to tell:
- The pull cord won’t retract: If you pull the cord and it doesn’t return to its starting position, it’s likely broken.
- The pull cord feels loose: A loose or floppy cord could indicate a broken spring or a detached wire.
- The engine doesn’t start: A broken pull cord will prevent the engine from getting the necessary spark to start.
If any of these symptoms apply, you’ll need to replace the pull cord.
Tools You’ll Need for the Job
Before you begin, make sure you have these essential tools:
- A new pull cord: This is the most important part. You can typically find a replacement cord at your local hardware store or online. Make sure to purchase one specifically designed for your mower model.
- Screwdriver: You’ll need a screwdriver to remove the screws holding the pull cord housing in place.
- Pliers: Pliers can help you grip and pull the old cord out and potentially adjust the spring tension.
- Wrench: A wrench might be needed to loosen or tighten any nuts holding the pull cord mechanism in place.
Step-by-Step Guide: Replacing the Pull Cord
1. Disconnect the Spark Plug: This is a crucial safety step! Before you begin disassembling the pull cord mechanism, disconnect the spark plug wire to prevent accidental starting.
2. Remove the Pull Cord Housing: Locate the pull cord housing on the engine. This is usually a rectangular or circular plastic or metal cover. Remove the screws or bolts holding it in place using your screwdriver or wrench.
3. Release the Old Pull Cord: Inside the housing, you’ll find the old pull cord attached to a spring. Carefully pull the cord out of the housing. If the cord is stuck or broken, use your pliers to gently pull it out, being careful not to damage the surrounding mechanism.
4. Remove the Spring: The spring that assists the pull cord retraction might be connected to the old cord. Carefully remove the spring from the old cord, ensuring you don’t lose any small parts.
5. Install the New Pull Cord: Thread the new pull cord through the pull cord housing. It’s important to ensure the cord goes through the correct hole and is positioned correctly within the housing.
6. Connect the New Spring: Attach the new spring to the new pull cord. Some springs are already attached to the new cord, while others might require you to attach them.
7. Reassemble the Housing: Secure the pull cord housing back in place using the screws or bolts you removed earlier. Make sure the housing is tightly secured to prevent any movement or rattling during use.
8. Reconnect the Spark Plug: Once the pull cord housing is secured, reconnect the spark plug wire to the engine.
9. Test the New Pull Cord: Carefully pull the new cord to ensure it retracts smoothly and operates as intended.
10. Troubleshooting: If your lawn mower still won’t start, check the following:
- Spark plug connection: Ensure the spark plug wire is properly connected and the spark plug itself is in good working condition.
- Fuel: Make sure your mower has enough fuel and that the fuel lines are not clogged.
- Air filter: A dirty air filter can affect engine performance. Clean or replace the air filter if necessary.
Tips for a Smooth Replacement
- Take photos: Before you start taking anything apart, it can be helpful to take pictures of the existing setup. This will help you remember how everything was assembled and make reassembly easier.
- Use a lubricant: Applying a light lubricant to the pull cord and spring can help prevent rust and ensure smooth operation.
- Check the spring tension: Ensure the spring has enough tension to retract the cord smoothly. If it’s too loose, the cord might not retract properly, and if it’s too tight, it could put unnecessary strain on the engine.
- Don’t force it: If you encounter resistance during any part of the process, don’t force it. Stop and carefully assess the situation to avoid damaging any parts.
Frequently Asked Questions
1. Can I replace just the cord and keep the old spring? While technically possible, it’s not recommended. The spring often wears out alongside the cord, and reusing an old spring can result in uneven tension and affect the lifespan of the new cord.
2. Can I replace the pull cord without removing the engine? It’s generally easier to remove the pull cord housing with the engine off. However, some mower models allow for access to the pull cord mechanism without detaching the engine. Consult your user manual for specific instructions.
3. What are some common pull cord problems? Besides breaking, common issues include fraying, stretching, and a worn-out spring. A frayed cord can snag, while a stretched cord might not engage with the engine properly.
4. How often should I replace my pull cord? There’s no set schedule for replacement. It depends on usage and how the cord is treated. A frayed or stretched cord should be replaced immediately.
5. What if I can’t find a replacement cord for my specific model? Check with a local repair shop or an online retailer specializing in small engine parts. They may have a generic cord that can be adapted for your model.
Conclusion: You’re Ready to Mow Again!
Replacing a broken pull cord is a simple repair that can be accomplished by most DIY enthusiasts. With a little patience and the right tools, you can get your lawn mower back in working order and tackle those overgrown patches of grass. Remember to follow the steps carefully, prioritize safety, and don’t hesitate to consult your mower’s manual for specific instructions. Now, get out there and enjoy a beautifully manicured lawn!
