Understanding Lawn Mower Pull Cord Springs
Pull cord springs play a crucial role in the proper functioning of your lawn mower. They help retract the cord smoothly, allowing you to start the mower efficiently.
What Is a Pull Cord Spring?
A pull cord spring, also known as a recoil spring, is a coiled component located within the pull start assembly. This spring tenses when you pull the cord and releases its tension to rewind the cord back into position once the mower starts. Its design allows for quick and efficient retraction, essential for the mower’s startup process.
Common Issues with Pull Cord Springs
Several common problems can affect pull cord springs. Here’s what you might encounter:
- Broken Spring: A broken spring won’t retract the cord, leaving it either fully extended or stuck. This issue often arises from wear and tear or improper maintenance.
- Rust or Corrosion: Rust can build up on the spring, causing it to stick or become less elastic. Regular checks can help prevent this.
- Misalignment: If the spring is misaligned during installation, it may not function smoothly. Ensure it’s seated correctly within the housing.
- Debris Blockage: Dirt, grass clippings, or other debris can obstruct the spring’s movement. Keeping the area clean can mitigate this problem.
Addressing these issues promptly can restore your mower’s functionality and prevent more significant repairs down the line.
Tools Needed for Repair
To fix the lawn mower pull cord spring, gather the following tools. Having the right tools simplifies the repair process and ensures effective results.
Essential Tools
- Screwdriver Set: Use a flathead and Phillips screwdriver to remove screws on the engine casing.
- Pliers: Utilize pliers to grasp and manipulate small components, especially while dealing with the spring.
- Socket Wrench: Employ a socket wrench for loosening bolts securely attached to the recoil assembly.
- Replacement Pull Cord: Keep a replacement pull cord handy in case the existing one is frayed or damaged.
- Replacement Spring: Acquire a new pull cord spring if the original is broken or rusted.
- Torque Wrench: Consider using a torque wrench for precise tightening of bolts if recommended by the manufacturer.
- Wire Brush: A wire brush helps clean off rust or debris, improving the longevity of your mower’s components.
- Safety Goggles: Wear safety goggles to protect your eyes from any potential debris during the repair.
- Lubricant: Use a lubricant for maintaining smooth movement in the recoil system once repairs are complete.
Step-by-Step Guide to Fixing the Pull Cord Spring
Follow these steps to effectively fix your lawn mower’s pull cord spring.
Removing the Pull Cord Assembly
- Gather Tools: Use a screwdriver set, pliers, and a socket wrench.
- Disconnect the Spark Plug: Ensure safety by disconnecting the spark plug wire to prevent accidental starting.
- Unscrew the Assembly: Locate the screws securing the pull cord assembly. Use the appropriate screwdriver to remove them.
- Remove the Pull Cord: Gently pull the assembly away from the mower, being cautious not to damage any attached components.
Inspecting the Spring
- Visual Inspection: Check the spring for any visible signs of damage, such as breaks or bends.
- Assess Rust or Corrosion: Examine the spring for rust. Look for areas that appear worn or have a rough texture.
- Test Alignment: Ensure the spring aligns correctly within the assembly. Misalignment may prevent proper retraction of the cord.
Replacing or Rewinding the Spring
- Replace the Spring: If the spring is broken, use a replacement spring that matches your mower’s specifications.
- Rewind the Spring: If the spring is intact, rewind it carefully. Hold the spring in place and turn it clockwise until it has enough tension to retract the cord effectively.
- Secure the Spring: Ensure the spring sits correctly within the assembly grooves to avoid misalignment.
- Thread the Cord: Insert the pull cord through the housing and back into the handle. Make sure it feeds through the designated slot.
- Tie a Knot: Secure the cord with a knot at the handle end to prevent it from slipping back through the housing.
- Reattach the Assembly: Position the pull cord assembly back onto the mower. Align it with the screw holes and fasten with screws.
- Reconnect the Spark Plug: Reattach the spark plug wire, ensuring everything is secured.
By following these steps, you can repair your lawn mower’s pull cord spring and keep your mower running smoothly.
