This guide will equip you with the knowledge and skills to tackle a broken pull cord, saving you from the hassle and expense of a trip to the repair shop. We’ll delve into identifying the culprit, choosing the right replacement, and guiding you through each step of the replacement process, leaving you feeling confident to conquer any pull cord woes.

A Brief Overview

Changing a lawn mower pull cord is a relatively straightforward task that can be tackled by anyone with basic mechanical aptitude. It involves identifying the damaged cord, locating the correct replacement, and then carefully disassembling the starter housing, replacing the cord, and reassembling everything. This article will break down the process step-by-step, ensuring that even the most novice mechanic can complete this repair with ease.

Identifying the Issue: Why is Your Pull Cord Broken?

Before diving into the replacement, it’s important to understand why your pull cord may have given up. There are a few common culprits:

  • Wear and Tear: Like any mechanical part, the pull cord is subject to wear and tear over time. Frequent use can lead to fraying, stretching, or even complete snapping of the cord.
  • Improper Use: Pulling the cord too aggressively or at an awkward angle can put undue stress on the cord, leading to damage.
  • Starter Housing Issues: Occasionally, the problem might lie within the starter housing itself, such as a broken spring or a jammed recoil mechanism.

Troubleshooting

Before jumping into a replacement, check the following:

  • Examine the Cord: If the cord is simply frayed or stretched, you may be able to temporarily fix it by cutting off the damaged section and securing the ends with a knot.
  • Check for Obstacles: Ensure there are no objects stuck in the starter housing that could be preventing the cord from retracting properly.
  • Test the Recoil Spring: Give the pull cord a gentle tug. If the spring feels weak or broken, it’s likely that the issue lies within the starter housing and will require more extensive repairs.

Choosing the Right Pull Cord

Once you’ve confirmed that the pull cord itself needs replacement, you’ll need to find the correct one for your lawn mower.

  • Manufacturer’s Information: Check the owner’s manual for your lawn mower. It often provides details about the specific pull cord required, including its length, thickness, and any other specific features.
  • Model Number: If you don’t have the manual, try to locate the model number of your lawn mower. This information is usually found on a sticker or a metal plate on the mower itself. You can then use the model number to search for replacement parts online or at a local hardware store.
  • Measure the Old Cord: As a last resort, you can measure the length and thickness of your old cord and use that information to find a compatible replacement.

Important Note: Ensure the new pull cord is compatible with your lawn mower’s starter housing. Different models may have different cord sizes and attachment points.

Replacing the Pull Cord: A Step-by-Step Guide

With the new pull cord in hand, you’re ready to begin the replacement process. This guide assumes a typical lawn mower starter housing design. Always refer to your owner’s manual for specific instructions tailored to your mower model.

Step 1: Disassembling the Starter Housing

  1. Locate the Starter Housing: The starter housing is typically located on the side of the engine, usually near the air filter.
  2. Remove the Housing Cover: Most starter housings have a cover held in place by screws or clips. Use a screwdriver or a small tool to remove these fasteners and carefully remove the cover.
  3. Disconnect the Pull Cord: The pull cord will be attached to the starter housing. Locate the attachment point and carefully disconnect the cord.

Step 2: Replacing the Pull Cord

  1. Attach the New Cord: Thread the new pull cord through the starter housing according to the manufacturer’s instructions. Typically, you’ll need to thread the cord through a series of holes or guides within the housing.
  2. Secure the Attachment Point: Once the cord is threaded, secure it to the attachment point. This usually involves a small hook or a similar fastening mechanism.
  3. Test the Recoil Mechanism: Before reassembling the housing, manually pull the cord to ensure it retracts smoothly and without any binding.

Step 3: Reassembling the Starter Housing

  1. Replace the Housing Cover: Carefully align the housing cover and re-attach the screws or clips that were removed earlier.
  2. Test the Pull Cord: Start the mower and test the new pull cord. Ensure it operates smoothly and without any resistance.

Tips for Success

  • Safety First: Before working on the lawn mower, always disconnect the spark plug wire and ensure the engine is completely cool.
  • Clean as You Go: Take advantage of the opportunity to clean the starter housing and the surrounding area. This will help to prevent dirt and debris from interfering with the new pull cord.
  • Grease the Mechanism: Apply a small amount of lubricant to the recoil mechanism and the pull cord to ensure smooth operation.
  • Store the Old Cord: Keep the old pull cord in case you need to use it as a reference when purchasing a replacement in the future.

Conclusion

By following this guide, you can tackle a broken pull cord with confidence and restore your lawn mower to its former glory. Remember, preventative maintenance is key to keeping your lawn mower in tip-top shape. Regularly inspecting the pull cord for wear and tear, and cleaning the starter housing, will help to prolong its lifespan and avoid unexpected repairs.

Frequently Asked Questions

1. Why Does My Lawn Mower’s Pull Cord Break?

The pull cord on a lawn mower is a crucial part of the starting mechanism, and it can break for several reasons. The most common cause is wear and tear from frequent use. The cord itself can fray or stretch over time, especially if it’s not properly maintained. Additionally, improper use, like pulling the cord too forcefully, can also lead to breakage. Another factor is the age of the cord, as older cords are more susceptible to damage. Therefore, it’s important to inspect the cord regularly for signs of wear and tear and replace it if necessary.

2. What Tools Do I Need to Replace the Pull Cord?

To replace the pull cord on your lawn mower, you’ll need a few basic tools. The most essential is a screwdriver, as you’ll need it to remove the engine cover and access the pull cord mechanism. A pair of pliers will be helpful for gripping and removing the old cord. A small pair of needle-nose pliers might be necessary for reaching into tight spaces. You’ll also need a new pull cord that’s compatible with your lawn mower model. You can find replacement cords at most hardware stores or online retailers.

3. How Do I Choose the Right Pull Cord Replacement?

Choosing the right replacement pull cord for your lawn mower is crucial for ensuring proper operation. The most important factor is the length of the cord. If the new cord is too short, it won’t reach the starter mechanism effectively. If it’s too long, it could cause the cord to tangle or get caught during operation. Additionally, the cord should be made of durable materials like nylon or steel cable, and the thickness should match the original cord. It’s best to check the model number of your lawn mower to ensure compatibility with the replacement cord.

4. How Often Should I Replace the Pull Cord?

There’s no specific timeframe for replacing a pull cord, as it depends on factors like frequency of use and overall maintenance. However, you should inspect the cord regularly for signs of wear and tear. If you notice any fraying, stretching, or damage, it’s best to replace it immediately. It’s also a good idea to replace the cord every few years, even if it doesn’t show signs of damage. This preventative measure can help avoid unexpected breakdowns and ensure smooth operation of your lawn mower.

5. Can I Use a Different Type of Cord for My Lawn Mower?

It’s generally not recommended to use a different type of cord for your lawn mower, as it can affect the performance and safety of the machine. Different types of cords have varying strengths and flexibility, which can affect how easily the engine starts and how smoothly the cord retracts. It’s best to use a replacement cord specifically designed for your lawn mower model to ensure optimal performance and avoid any potential problems.

6. Can I Fix a Broken Pull Cord Without Replacing It?

It’s not recommended to try fixing a broken pull cord, as it usually involves splicing the broken ends together, which can weaken the cord and create a safety hazard. Additionally, if the cord is frayed or stretched, repairing it won’t address the underlying issue. The best course of action is to replace the entire cord to ensure reliable and safe operation of your lawn mower.

7. What if I’m Not Comfortable Replacing the Pull Cord Myself?

If you’re not comfortable replacing the pull cord yourself, you can always take your lawn mower to a qualified repair shop. A mechanic will be able to assess the situation, replace the cord correctly, and ensure that your lawn mower is functioning properly. This option is particularly helpful if you’re unfamiliar with the workings of your lawn mower or if you don’t have the necessary tools and skills to perform the replacement yourself.
