The frustration of a broken lawn mower pull cord is all too familiar. You’re ready to tackle your lawn, and suddenly, your trusty machine refuses to cooperate. Instead of throwing your hands up in despair, take a deep breath and reach for your toolbox. Replacing a lawn mower pull cord is a simple task that can save you money and get you back to mowing in no time. This article will walk you through the process, step-by-step, with clear instructions and helpful tips. We’ll cover everything from identifying the right replacement cord to properly installing it, ensuring a smooth and efficient mowing experience.
A Quick Overview of Lawn Mower Pull Cord Replacement
The pull cord on a lawn mower acts as the primary starting mechanism. It connects to the engine crankshaft, transferring your pull to the engine’s flywheel, causing it to spin and start. When the cord breaks or wears out, it prevents the engine from starting. Replacing it involves removing the old cord, attaching a new one, and securing it back in place.
Identifying the Problem and Choosing the Right Cord
Before embarking on the repair, you need to confirm that the issue is indeed a broken pull cord. A few telltale signs point to this problem:
- The cord snaps or breaks when pulled. This is the most obvious indication.
- The cord feels loose or detached.
- The cord retracts slowly or not at all. This could be due to a damaged spring.
- The engine doesn’t crank or start when you pull the cord.
Once you’ve confirmed that the pull cord is the culprit, you’ll need to choose a replacement. Here are the factors to consider:
Understanding Your Lawn Mower’s Pull Cord System
Most lawn mowers utilize a simple recoil starter system, but the specific type of cord and its attachment mechanisms vary. Familiarize yourself with the existing cord to find a suitable replacement:
- Cord Length: Measure the length of the old cord to ensure you get a new one that’s appropriately sized. A cord that’s too short won’t allow for a full pull, while one that’s too long can create tangling and make starting difficult.
- Cord Material: The most common pull cord material is nylon. It’s durable and resistant to wear. However, some mowers may use rope or other materials. Make sure the replacement cord matches the original material.
- Attachment Method: Pay attention to how the cord is attached to the recoil starter housing. Most lawn mowers use a simple metal loop that clips onto the housing. Some have a different attachment mechanism, such as a screw-on system.
Where to Find a Replacement Cord
You can easily find replacement lawn mower pull cords at local hardware stores, online retailers, and even some automotive stores.
When searching for a replacement, provide the following information:
- Make and model of your lawn mower.
- Type of recoil starter system.
- Length and material of the old cord.
- Attachment method.
Tools You’ll Need for the Job
To replace the pull cord, you’ll need a few basic tools:
- Screwdriver (Phillips and flathead)
- Pliers
- Wire cutters or a sharp knife
- New pull cord
Step-by-Step Guide to Replacing a Lawn Mower Pull Cord
With your tools gathered and your replacement cord ready, follow these steps:
1. Disconnect the Spark Plug
This crucial step ensures your safety during the repair process. Disconnect the spark plug wire to prevent accidental starting of the engine.
Here’s how:
- Locate the spark plug, usually near the top of the engine.
- Pull the spark plug wire off the spark plug.
- Place the wire safely away from the engine.
2. Remove the Recoil Starter Housing
The recoil starter housing is the part that holds the pull cord and spring mechanism. You’ll need to remove it to access the cord attachment point.
Here’s how:
- Identify the screws holding the housing in place. They are usually located around the perimeter of the housing.
- Use a screwdriver to remove these screws.
- Carefully detach the housing from the engine.
3. Disconnect the Old Pull Cord
Now that the housing is removed, you can disconnect the old cord.
Here’s how:
- Locate the metal loop or other attachment point on the old cord.
- If it’s a metal loop, use pliers to carefully detach it from the housing.
- If it’s a screw-on system, use a screwdriver to loosen and remove the screw.
- Carefully pull the old cord out of the housing.
4. Install the New Pull Cord
With the old cord out of the way, you can install the new one.
Here’s how:
- Attach the new cord to the recoil starter housing using the same method as the old cord (metal loop or screw-on system).
- Thread the new cord through the housing. It should run smoothly through the housing’s grooves.
5. Reassemble the Recoil Starter Housing
Once the new cord is installed, you can reassemble the housing.
Here’s how:
- Carefully align the housing with the engine.
- Secure the housing in place with the screws you removed earlier.
6. Reconnect the Spark Plug Wire
Now that the housing is reassembled, you can reconnect the spark plug wire.
Here’s how:
- Locate the spark plug wire and attach it securely to the spark plug.
7. Test the New Pull Cord
With everything in place, it’s time to test your work.
Here’s how:
- Pull the cord gently a few times to ensure it’s functioning correctly. It should retract smoothly and without snags.
- Once you’re confident, you can try starting the engine.
Important Tips for Replacing a Pull Cord
- Lubricate the cord: Before installing the new cord, apply a small amount of lubricant, such as WD-40, to the cord and the housing. This will help the cord run smoothly and prevent premature wear.
- Check the spring: If the pull cord doesn’t retract smoothly, the spring inside the recoil starter housing might be worn or broken. You’ll need to replace the spring.
- Clean the housing: While you have the housing removed, use a brush or compressed air to clean out any debris or dust that may be obstructing the cord’s movement.
- Wear safety glasses: Always wear safety glasses when working on your lawn mower to protect your eyes from any flying debris.
Troubleshooting Common Problems
If you’re having trouble with your new pull cord, here are some common problems and how to fix them:
- The cord is too loose: The attachment point might not be secure. Double-check that the loop is securely attached or the screw is tight.
- The cord gets tangled: This is usually caused by a problem with the cord’s path through the housing. Make sure the cord is properly threaded through the grooves.
- The cord retracts too quickly: This could be caused by a weak spring or excessive lubrication. Adjust the lubrication or replace the spring.
Keep Your Lawn Mower Running Smoothly
