10 Methods How to Replace Pull Cord on Lawn Mower
1. Gather the Necessary Tools and Parts
Before beginning the replacement process, gather all necessary tools and parts. You will need a replacement pull cord, which can be purchased at a hardware store or online. Additionally, prepare tools such as a screwdriver, a socket set or wrench, and a pair of pliers.
A new pull cord typically comes with a recoil starter assembly, but if not, ensure that the cord is of the correct length and strength. Having all tools and parts ready will streamline the replacement process and help you avoid interruptions.
2. Disconnect the Spark Plug
For safety reasons, disconnect the spark plug before working on the pull cord. This prevents the engine from accidentally starting while you’re replacing the cord. Locate the spark plug, usually found on the side of the engine, and detach the spark plug wire by pulling it off the terminal.
This step ensures that there is no electrical power to the engine, reducing the risk of injury or damage during the repair process.
3. Remove the Recoil Starter Assembly
The recoil starter assembly is the part that houses the pull cord mechanism. To access it, you need to remove it from the engine. This typically involves unscrewing the bolts or screws that secure the assembly to the engine.
Use a screwdriver or socket set to remove these fasteners carefully. Once the recoil starter is free, lift it away from the engine to expose the pull cord and internal components. Handling the recoil starter with care ensures that you do not damage any parts during removal.
4. Remove the Old Pull Cord
With the recoil starter assembly removed, you can access the old pull cord. Carefully unwind the old cord from the recoil starter’s spool. The pull cord is typically wound around a spring-loaded spool inside the assembly.
Use pliers to pull the cord out of the handle and spool, being cautious not to damage the internal spring or other components. If the old cord is frayed or broken, it should come out relatively easily. Proper removal of the old cord is essential for installing the new one correctly.
5. Prepare the New Pull Cord
Before installing the new pull cord, prepare it by cutting it to the appropriate length. Most replacement pull cords come pre-cut, but it’s important to ensure that it is the correct length for your specific model.
Thread the new pull cord through the handle and ensure it is securely attached. If the new cord does not come with a handle, you may need to transfer the handle from the old cord or purchase a new one. Proper preparation of the new cord ensures that it functions correctly and provides reliable starting power.
6. Install the New Pull Cord
To install the new pull cord, begin by threading it through the recoil starter’s spool. Make sure the cord is wound tightly and evenly around the spool. Align the cord with the groove on the spool to ensure smooth operation.
Attach the cord to the recoil starter’s handle, securing it with knots or fasteners as needed. It’s crucial to wind the cord in the same direction as the original cord to ensure proper tension and operation. Follow the manufacturer’s instructions for specific installation procedures, as they may vary by model.
7. Reassemble the Recoil Starter
Once the new pull cord is installed, reassemble the recoil starter assembly. Align the starter with the mounting holes on the engine and secure it in place with the screws or bolts you removed earlier. Tighten the fasteners securely, but be careful not to overtighten, as this can cause damage to the assembly or engine.
Ensure that the recoil starter is properly aligned and that the pull cord operates smoothly when tested. Proper reassembly ensures that the pull cord mechanism functions correctly and reliably.
8. Reconnect the Spark Plug
After reassembling the recoil starter, reconnect the spark plug wire to the spark plug. Make sure the wire is securely attached to the terminal to ensure proper electrical connection. Reconnecting the spark plug completes the safety precaution taken earlier and allows you to test the newly installed pull cord. Verify that the connection is firm and that there is no risk of disconnection during operation.
9. Test the New Pull Cord
With the mower reassembled and the spark plug reconnected, it’s time to test the new pull cord. Stand clear of the mower’s blade area and pull the cord to ensure it engages and retracts smoothly. The engine should start without issues if the pull cord is properly installed and adjusted. If the cord is difficult to pull or does not retract properly, check the tension and alignment of the recoil starter and adjust as needed. Testing the pull cord ensures that the mower is ready for use and that the repair was successful.
10. Perform Regular Maintenance
To prolong the life of your new pull cord and ensure reliable starting, perform regular maintenance on your lawn mower. Keep the pull cord and recoil starter clean and free from debris.
Check the cord periodically for signs of wear or fraying and replace it as needed. Regular maintenance helps prevent future issues and keeps your mower in optimal working condition. By staying proactive with maintenance, you can avoid unnecessary repairs and ensure that your lawn mower starts easily every time.
Common Mistakes to Avoid
When replacing a pull cord, there are several common mistakes that can hinder the repair process or lead to future issues. First, failing to ensure the correct length and type of pull cord can result in improper function, causing it to break or malfunction shortly after installation.
Second, neglecting to disconnect the spark plug before working on the recoil starter increases the risk of accidental engine starts, potentially leading to injury. Third, overtightening the screws or bolts during reassembly can damage the recoil starter assembly or the engine mounting points, which may lead to further complications.
Lastly, not testing the new pull cord before completing the job could mean overlooking alignment or tension issues, ultimately affecting the mower’s reliability. By being aware of these pitfalls, you can ensure a smoother and more effective pull cord replacement process.
