Overview
Replacing a lawn mower pull string is a relatively simple task that typically involves the following steps:
- Disassembling the Starter Assembly: This involves removing the housing that covers the pull string mechanism.
- Removing the Old Pull String: The old string is usually attached to a spring and needs to be carefully detached.
- Installing the New Pull String: The new string is then attached to the spring and threaded through the starter assembly.
- Reassembling the Starter Assembly: The housing is put back in place, ensuring all components are properly aligned.
Preparing for the Replacement
Before you start replacing the pull string, gather the necessary tools and materials. You’ll need:
- A new pull string: Make sure to purchase a string specifically designed for your lawn mower model.
- A Phillips screwdriver: This will be used to remove screws.
- A pair of pliers: This will help with the removal and installation of the string.
- A flat-head screwdriver: This may be needed to pry open certain components.
- A work surface: A clean, flat area will make the task easier.
Important Note: Before you begin working on your lawn mower, ensure that it is turned off and the spark plug wire is disconnected to prevent any accidental starts.
Disassembling the Starter Assembly
- Locate the Starter Housing: The starter housing is typically located on the top of the engine, near the pull string. It may be covered by a plastic or metal cover.
- Remove the Cover: Use your Phillips screwdriver to remove any screws holding the cover in place. If there are clips or latches, carefully pry them open.
- Remove the Starter Housing: Once the cover is removed, you should be able to see the starter housing. It may be held in place by screws or clips. Remove these fasteners and carefully lift off the housing.
Removing the Old Pull String
- Identify the Spring: The pull string is typically attached to a spring that sits inside the starter housing.
- Remove the String from the Spring: Carefully detach the old string from the spring. You may need to use pliers to help you pull it free.
- Release the String from the Starter: The old string is also threaded through the starter assembly. Locate the point where the string is anchored to the starter. You may need to use a flat-head screwdriver to pry open any clips or fasteners that are holding the string in place.
Installing the New Pull String
- Attach the String to the Spring: Thread the new pull string through the hole in the spring. Make sure that the string is securely fastened to the spring, but avoid overtightening it.
- Thread the String Through the Starter: Carefully thread the new pull string through the starter assembly, following the path of the old string.
- Secure the String to the Starter: Once the string is threaded through the starter, secure it to the designated anchoring point. This may involve tightening a screw, snapping a clip, or using a similar mechanism.
Reassembling the Starter Assembly
- Align the Starter Housing: Place the starter housing back on top of the starter assembly, ensuring that it is properly aligned.
- Secure the Housing: Fasten the housing in place using the screws or clips you removed earlier.
- Reattach the Cover: Replace the cover over the starter housing and secure it using the screws or latches.
Testing the New Pull String
- Reconnect the Spark Plug Wire: Before testing the new pull string, make sure to reconnect the spark plug wire to the engine.
- Test the Starter: Carefully pull the new string a few times to ensure it is working correctly. The pull string should feel smooth and consistent. If the pull string feels stiff or jerky, check to ensure the string is properly installed and that the spring is functioning properly.
Tips for Success
- Choosing the Right Pull String: Always refer to your lawn mower’s owner’s manual for the correct pull string length and specifications. Using the wrong string could damage your starter mechanism.
- Lubricating the Starter: After installing the new string, apply a small amount of lubricant to the moving parts of the starter mechanism. This will help to prevent wear and tear.
- Regular Maintenance: Check the pull string for signs of wear and tear on a regular basis. Replacing a frayed or broken string before it fails will help to prevent costly repairs.
