The lawnmower is a vital tool for any homeowner. It keeps the grass trimmed and your yard looking neat. However, like any other piece of machinery, it can require maintenance. One common problem that lawnmower owners face is a broken recoil spring. This spring helps you start the mower by retracting the starter rope when you pull it. When it breaks, starting your mower becomes a struggle. Thankfully, replacing a recoil spring is a relatively simple DIY job. This article will walk you through the process step-by-step, equipping you with the knowledge to get your mower back in action quickly.
What is a Recoil Spring and Why Does it Break?
The recoil spring is a vital component of a lawnmower’s starting system. It’s a powerful spring housed inside the starter housing, connected to the starter rope. When you pull the rope, the spring extends, winding up energy. As you release the rope, the spring retracts, spinning the engine’s crankshaft and initiating the combustion cycle. This starts the mower.
Over time, the spring can fatigue and break due to repeated use and exposure to the elements. The constant stress of winding and unwinding can cause metal fatigue, leading to a sudden snap. Additionally, rust and corrosion can weaken the spring’s integrity, making it more prone to breakage.
Preparing for the Replacement
Before you start, you’ll need to gather the following supplies:
- New Recoil Spring: Ensure you get the correct spring for your model.
- Screwdriver: A Philips head screwdriver will be needed to remove the starter housing screws.
- Wrench: You might need a wrench to remove any nuts holding the starter housing in place.
- Gloves: Protect your hands from sharp edges and dirt.
- Safety Glasses: Protect your eyes from flying debris.
Disassembly: Accessing the Recoil Spring
- Safety First: Disconnect the spark plug wire to prevent accidental starting.
- Locate the Starter Housing: Identify the starter housing on your mower. It’s usually a round or rectangular housing with a rope pull handle.
- Remove the Housing: Use your screwdriver to remove the screws securing the starter housing to the mower. You might need to remove a nut or two as well.
- Remove the Old Spring: Carefully detach the old recoil spring from the starter housing and the starter rope. Note how it was attached so you can reassemble it correctly.
Installing the New Recoil Spring
- Attach the New Spring: Align the new recoil spring with the starter rope and the starter housing, mirroring the position of the old spring.
- Secure the Spring: Carefully attach the new spring to the starter housing and the starter rope. Make sure it’s securely connected to avoid any loosening during use.
- Reassembly: Reassemble the starter housing, ensuring the screws are properly tightened.
- Reconnect the Spark Plug: Reconnect the spark plug wire.
Testing and Final Checks
Once the new spring is installed, it’s time to test it.
- Pull the Rope: Pull the starter rope several times to ensure the spring is functioning properly and retracting smoothly.
- Check for Smooth Operation: Ensure that the rope isn’t catching or sticking. The spring should smoothly retract the rope without any resistance or noise.
- Start the Mower: Attempt to start the mower. If it starts easily, your new recoil spring is installed correctly.
Tips for Prolonging the Life of Your Recoil Spring
- Proper Maintenance: Regularly check the recoil spring for any signs of wear or tear.
- Lubrication: Lubricate the spring mechanism with a light oil or grease to prevent rust and corrosion.
- Avoid Over-Pulling: Pulling the starter rope too forcefully can put undue stress on the spring, leading to premature failure.
- Proper Storage: Store your lawnmower in a dry place to protect the spring from moisture.
