The rhythmic hum of your lawn mower, the fresh-cut scent of grass, and the satisfaction of a perfectly manicured lawn – these are the joys of homeownership. But what happens when that familiar hum turns into a sputtering cough and your lawn mower refuses to cooperate? It’s likely a problem with the recoil starter, and more often than not, the issue is a worn-out or broken cord.
This article will guide you through the process of restringing your lawn mower cord, offering a step-by-step solution to get your mower back in action. We’ll cover identifying the necessary parts, understanding the process, and assembling the new cord correctly. With a few basic tools and some patience, you can save yourself a trip to the repair shop and tackle this common lawn mower repair yourself.
The Basics of Lawn Mower Cord Restringing
The recoil starter is the mechanism that lets you start your lawn mower with a pull. The cord is what you pull, and the spring inside the mechanism is what drives the engine. When the cord breaks or wears out, the starter mechanism won’t work properly, and your mower won’t start.
Restringing a lawn mower cord involves replacing the worn or broken cord with a new one. This usually involves taking the starter mechanism apart, removing the old cord, installing the new cord, and reassembling the mechanism. The exact process will vary slightly depending on your lawn mower model, but the general steps are the same.
Tools and Materials You’ll Need
Before diving into the restringing process, gather the following tools and materials:
- New recoil starter cord: Make sure to get a cord that is compatible with your specific lawn mower model.
- Phillips screwdriver: To remove screws on the starter mechanism.
- Flathead screwdriver: To pry apart the starter mechanism if necessary.
- Needle-nose pliers: For handling small parts and making precise adjustments.
- Safety glasses: To protect your eyes from flying debris.
- Work gloves: For a firm grip and to protect your hands from sharp edges.
- A clean work area: To prevent losing small parts and maintain organization.
Identifying the Recoil Starter
The recoil starter is usually located on the side of the engine, near the pull cord handle. It’s a round, metal housing that contains the spring, cord, and other parts. Look for a small metal latch or a spring-loaded catch on the side of the housing. This is where the pull cord is connected.
Understanding the Recoil Starter
To understand how the recoil starter works, it’s helpful to visualize its components:
- Housing: This is the outer casing that protects the internal parts.
- Spring: The coiled spring provides the power to start the engine.
- Cord: The cord you pull to engage the spring.
- Pawl and Ratchet: These mechanisms control the release and retraction of the cord, engaging the spring.
- Starter Dog: This connects to the engine’s crankshaft, allowing the engine to turn.
Step-by-Step Guide to Restringing a Lawn Mower Cord
Now that you have the necessary tools and understand the mechanism, let’s get started!
Step 1: Disassembling the Recoil Starter
- Remove the pull cord handle: Look for a screw or nut holding the handle in place. Use a Phillips screwdriver to remove it.
- Remove the housing cover: On some mowers, there might be a spring clip or a small screw holding the housing cover in place. Remove these to access the inner mechanism.
- Release the cord: Locate the metal latch or spring-loaded catch on the housing. This is where the cord is connected. Release the cord by pushing on the latch or using a screwdriver to pry it open.
Step 2: Removing the Old Cord
- Inspect the cord: Carefully examine the old cord for breaks, fraying, or excessive wear. This will help you determine the cause of the starting issue.
- Locate the attachment points: The old cord will be connected to the housing at multiple points. Identify these points and note how the cord is routed.
- Remove the cord: Use your needle-nose pliers to carefully detach the old cord from the housing. Be cautious not to damage any other components.
Step 3: Installing the New Cord
- Attach the new cord: Follow the same path as the old cord, connecting it to the same attachment points on the housing. Make sure the cord is securely fastened.
- Route the cord: Guide the new cord through the housing and ensure it is routed correctly. There might be specific grooves or channels for the cord to follow.
- Rewind the cord: While holding the cord taut, turn the spool manually to wind the cord around the drum. This is similar to rewinding a fishing reel.
Step 4: Reassembling the Recoil Starter
- Reinstall the housing cover: Replace the housing cover and secure it with the spring clip, screw, or other fastening mechanism.
- Reinstall the pull cord handle: Secure the handle with the screw or nut you removed earlier.
- Test the pull cord: Gently pull the cord several times to ensure it retracts smoothly and without snags.
Step 5: Troubleshooting
- Check for smooth operation: Ensure the cord retracts smoothly and the spring engages without any binding or resistance.
- Ensure proper cord tension: There should be a slight tension in the cord when it is fully retracted. This tension helps the starter mechanism engage correctly.
- Check for loose parts: Ensure all screws and nuts are secure, and there are no loose or missing parts.
Final Tips
- Use a new cord every time: Using a used or partially worn cord will only cause problems in the future.
- Replace worn parts: If you find other components are worn out during the restringing process, replace them as well.
- Always wear safety glasses and gloves: This will protect you from injury while working on your lawn mower.
- Follow the manufacturer’s instructions: Refer to your lawn mower manual for specific instructions and guidance on restringing the cord.
When to Call a Professional
While restringing a lawn mower cord is a relatively simple task, there are certain situations when it’s best to consult a professional.
- If the starter mechanism is damaged: If the housing, spring, or other internal components are broken or damaged, you may need a professional repair.
- If the engine is not starting: If the mower still won’t start after restringing the cord, there might be a deeper problem with the engine.
- If you’re uncomfortable with the process: If you’re unsure about the process or feel uncomfortable disassembling your mower, it’s better to leave it to a professional.
