Replacing a pull cord on a lawnmower involves detaching the old cord, routing the new cord through the mower’s housing, and securely attaching it to the engine. This article will guide you through the entire process, covering tools, safety measures, and troubleshooting tips. Whether you’re a seasoned DIY enthusiast or a novice home mechanic, you’ll find this guide invaluable in tackling your next lawnmower repair project.
Understanding the Pull Cord System
The pull cord is essential for starting a lawnmower. It connects to the recoil starter mechanism, which in turn engages the engine. The pull cord’s function is to wind the recoil spring, generating the force needed to crank the engine. When the cord snaps, the recoil spring loses tension, and the engine becomes impossible to start.
Tools and Materials You’ll Need
Before you begin, gather the following tools and materials:
- New pull cord: Make sure to purchase a replacement cord compatible with your lawnmower model.
- Phillips screwdriver: This will be used to remove screws.
- Needle-nose pliers: These are helpful for maneuvering the pull cord.
- Wire cutters: You’ll use these to cut the old cord.
- Gloves: Wear gloves to protect your hands from sharp edges.
- Work surface: Choose a clean and well-lit area.
- Optional: Small pry bar or flathead screwdriver: This may be useful to help remove parts if they’re stuck.
Safety Precautions
Safety is paramount when working with lawnmowers. Follow these precautions to avoid injuries:
- Disconnect the spark plug: This ensures the engine won’t accidentally start.
- Wear safety glasses: Protect your eyes from flying debris.
- Be aware of sharp edges: Lawn mowers have many sharp parts, handle them with care.
- Do not work on the mower while it’s running.
Step-by-Step Guide to Replacing a Pull Cord
Now that you have the necessary tools and have ensured safety, let’s get started:
1. Disassemble the Pull Cord Assembly
1.1 Disconnect the spark plug: Locate the spark plug on the engine and disconnect its wire.
1.2 Remove the recoil starter cover: Identify the cover housing the pull cord mechanism. It’s usually located on the top of the engine. Use a Phillips screwdriver to remove the screws holding the cover in place.
1.3 Remove the old pull cord: Carefully disconnect the old cord from the recoil starter mechanism. This may involve pulling the cord out of a small hook or slot.
2. Prepare the New Pull Cord
2.1 Cut the new cord: Measure the old cord and cut the new one to the same length. This ensures proper tension in the recoil spring.
2.2 Attach the new cord to the recoil starter: Thread the new cord through the pulley or groove on the recoil starter mechanism, following the same path as the old cord.
3. Reassemble the Pull Cord Assembly
3.1 Connect the new cord to the recoil starter: Ensure the new cord is securely connected to the recoil starter. It should be firmly attached without any slack.
3.2 Reinstall the recoil starter cover: Carefully reattach the cover, making sure the screws are securely fastened.
3.3 Reconnect the spark plug: Plug the spark plug wire back into the spark plug.
4. Test the New Pull Cord
4.1 Start the lawnmower: Try starting the lawnmower to ensure the new pull cord functions correctly. If the engine starts smoothly, you’ve successfully replaced the pull cord.
5. Troubleshooting Common Problems
5.1 The engine doesn’t start: Check the following:
* Secure connections: Ensure the spark plug is connected and the new cord is securely attached to the recoil starter.
* Tension: The recoil spring must have enough tension. If the cord feels loose, adjust it by pulling the cord out a bit further and securing it.
* Obstruction: Verify that the pull cord’s movement isn’t obstructed by any debris or parts.
* Fuel and spark: Ensure the lawnmower has fuel and that the spark plug is functioning correctly.
5.2 The pull cord feels too tight:
* Excess cord: If the cord is too long, it will create excessive tension. Cut the excess length to adjust it.
6. Maintenance Tips
6.1 Regular lubrication: Apply a light lubricant to the recoil starter mechanism every few months to prevent rust and friction.
6.2 Inspect the cord: Check the cord for wear and tear regularly. Replace it promptly if you see any fraying or damage.
