Step-by-Step Guide
Replacing a lawn mower pull cord involves a few straightforward steps. Follow these instructions to get your mower back in working condition.
Remove the Old Pull Cord
- Disconnect Spark Plug: Start by removing the spark plug wire for safety.
- Take Off the Housing: Use a screwdriver to unscrew the housing that covers the recoil starter. This often requires a wrench or socket set.
- Locate Pull Cord: Look for the damaged pull cord inside the recoil mechanism. It typically wraps around a spool.
- Cut the Old Cord: Use scissors or pliers to cut the remnants of the cord, freeing it from the assembly.
- Remove the Spool: If necessary, take out the spool from the recoil starter carefully to access the pull cord mechanism.
Prepare the New Pull Cord
- Select Correct Cord: Choose a replacement pull cord that matches the old one in thickness and length. This ensures proper function.
- Cut to Length: Cut the new cord to the required length, usually about 6 feet. Adjust based on the specific mower model.
- Seal Ends: Lightly burn the ends of the cord to prevent fraying. This step helps ensure a neat installation.
- Feed Through Spool: Insert one end of the new pull cord through the spool. Wrap it in the same direction as the old cord.
- Secure to Handle: Thread the other end of the cord through the hole in the pull handle, tying a knot to secure it.
- Rewind the Spool: Wind the new cord around the spool tightly to create tension. Ensure it winds correctly to allow for a smooth pull.
- Reattach the Spool: Place the spool back into the recoil starter housing. Ensure it fits snugly.
- Reattach Housing and Spark Plug: Screw the housing back on, reconnect the spark plug wire, and check for functionality by pulling the cord to test the mechanism.
This methodical approach leads to a successful pull cord replacement, enabling your lawn mower to start smoothly again.
Troubleshooting Common Issues
When facing trouble with a lawn mower pull cord, understanding common issues helps you resolve them quickly.
Difficulty in Pulling the Cord
If you experience difficulty pulling the cord, check these factors:
- Stuck Engine: Ensure the engine isn’t stuck. Remove the spark plug and try pulling the cord again. If it pulls easily, you may have internal engine problems.
- Excessive Tension: Examine the cord tension. If it’s wound too tightly, it hampers the pull. Loosen the cord slightly during installation for better operation.
- Obstructions: Look for physical obstructions around the starter assembly. Clean any debris blocking movement, including grass clippings or dirt.
- Rust or Corrosion: Inspect the internal mechanism for rust or corrosion. Clean with a rust remover and lubricate parts to ensure smooth operation.
Cord Breakage
Cord breakage can stem from several causes. Here’s how to address them:
- Worn Out Material: Check your cord for signs of wear or fraying. Replace old cords with one of high quality and appropriate thickness.
- Improper Installation: Ensure correct installation of the new cord. Rethread it properly, making sure it isn’t twisted and is secured tightly in the slot.
- High-Stress Use: Avoid yanking the cord too forcefully. Pull evenly and steadily. This reduces strain on the cord and extends its life.
- Incompatible Parts: Make sure the replacement cord matches your model’s specifications. Using an incompatible cord leads to premature breakage.
By addressing these issues, you can maintain your lawn mower’s performance and extend the life of your pull cord.
Conclusion
Replacing a lawn mower pull cord might seem daunting but with the right tools and a bit of patience you can tackle it successfully. By following the steps outlined and keeping safety in mind you’ll have your mower up and running in no time.
