The feeling is unmistakable: a sudden yank on the lawn mower’s pull cord, followed by a sickening snap. Now, you’re left staring at a broken cord and a lawn that’s growing wilder by the minute. Don’t panic! Replacing a lawn mower pull cord is a simple DIY task that can save you a trip to the repair shop and a hefty bill. This guide will walk you through the process, from identifying the right replacement to installing it correctly. We’ll cover all the tools you’ll need, safety precautions, and troubleshooting tips, so you can get back to mowing in no time.
A quick overview: Replacing a lawn mower pull cord involves disconnecting the old cord, attaching the new one, and reassembling the housing. The process is straightforward but requires some basic mechanical skills and patience.
Identifying the Problem and Choosing the Right Replacement
Before you start dismantling your mower, ensure the problem is actually a broken pull cord and not something else.
- Check for Obstructions: Sometimes, debris can become lodged in the recoil housing, preventing the cord from retracting properly. Remove any visible obstructions and try pulling the cord again.
- Inspect the Recoil Spring: A weak or broken recoil spring can also cause issues. If you hear a faint clicking sound when pulling the cord, the spring might be the culprit.
- Check for a Stuck Engine: If the engine is seized, the pull cord might break under the strain. Try turning the engine shaft by hand to see if it moves freely.
If you’ve ruled out these issues and the cord is indeed broken, it’s time to get a replacement.
Choosing the Right Replacement
The right pull cord will depend on your specific lawn mower model. Here’s what to look for:
1. Length: The cord should be long enough to provide a comfortable grip and reach the engine without excessive tension.
2. Material: Most pull cords are made of nylon or braided steel. Choose a durable material that won’t easily fray or break.
3. Compatibility: Ensure the replacement cord is compatible with your lawn mower model. Check the manufacturer’s website or the original pull cord for specifications.
Tools and Materials You’ll Need
Here’s a list of the tools and materials you’ll need for the job:
- New pull cord: Make sure it’s compatible with your lawn mower model.
- Phillips screwdriver: For removing screws from the recoil housing.
- Flat-blade screwdriver: To pry open any clips or tabs holding the housing together.
- Wire cutters: To cut the old cord.
- Gloves: To protect your hands.
- Safety glasses: To protect your eyes.
Replacing the Pull Cord: A Step-by-Step Guide
Now, let’s get down to business and replace that broken cord. Follow these steps carefully:
Step 1: Disconnect the Spark Plug
Safety first! Always disconnect the spark plug to prevent accidental starting while working on the engine. Locate the spark plug, which is usually located on top of the engine. Use a wrench to loosen and remove the spark plug wire.
Step 2: Remove the Recoil Housing
The recoil housing is the plastic or metal casing that holds the pull cord assembly. Here’s how to remove it:
- Locate the screws: The recoil housing is usually held in place by several screws.
- Remove the screws: Use a Phillips screwdriver to carefully remove the screws.
- Remove the housing: Gently pry the recoil housing off the engine. There might be clips or tabs holding it in place; use a flat-blade screwdriver to carefully release them.
Step 3: Remove the Old Pull Cord
- Locate the cord ends: The old pull cord is attached to the recoil spring and a small metal hook or eyelet on the other end.
- Detach the cord: Carefully cut or detach the cord from the hook or eyelet. Use wire cutters to cleanly cut the cord close to the hook.
- Remove the recoil spring: The recoil spring might be held in place by a small pin or clip. Remove it carefully.
Step 4: Attach the New Pull Cord
- Attach to the recoil spring: Thread the new pull cord through the recoil spring and attach it to the hook or eyelet. Make sure the cord is securely attached.
- Attach the cord to the other end: Now, attach the other end of the cord to the metal hook or eyelet on the housing.
Step 5: Reassemble the Recoil Housing
- Attach the recoil spring: Place the recoil spring back into its housing and secure it with the pin or clip.
- Install the housing: Carefully align the recoil housing with the engine and reattach it using the screws you removed earlier.
- Tighten the screws: Tighten the screws securely, but avoid overtightening.
Step 6: Reconnect the Spark Plug
- Reattach the spark plug wire: Carefully reconnect the spark plug wire to the spark plug.
- Tighten the spark plug: Tighten the spark plug securely using the wrench.
Step 7: Test the New Pull Cord
- Pull the cord: Give the new pull cord a few gentle pulls to ensure it’s working correctly.
- Start the engine: Try starting the engine. If the new pull cord works, you’ve successfully replaced it.
Troubleshooting Tips
If you’re having trouble replacing the pull cord or it’s not working correctly, try these troubleshooting tips:
- Check for proper cord tension: Make sure the new cord is taut but not overly stretched. If it’s too loose, it might not be able to retract the recoil spring.
- Ensure the cord is routed correctly: The pull cord should be routed through the recoil spring and housing without any kinks or obstructions.
- Check for a faulty recoil spring: If the new pull cord doesn’t work properly, the recoil spring might be broken or damaged.
- Inspect for worn parts: Examine the recoil housing for any worn or damaged parts, especially the recoil spring seat and the hook or eyelet that holds the pull cord.
Conclusion
Replacing a lawn mower pull cord is a straightforward task that can be accomplished with a few basic tools and some patience. By following these steps carefully, you can save money on a repair shop visit and get your lawn mower back in working order quickly. Remember to always prioritize safety by disconnecting the spark plug before working on the engine and wearing appropriate protective gear. With a little bit of effort, you can have your lawn looking its best in no time.
