Cub Cadet Ss470 Pull Cord Replacement

Replacing the pull cord on a Cub Cadet SS470 snowblower is a common maintenance task. A worn or broken pull cord can prevent the engine from starting, rendering the snowblower useless during critical times. This article provides a step-by-step guide to safely and effectively replacing the pull cord on your Cub Cadet SS470.

Tools and Materials Needed

Before beginning the replacement process, gather the necessary tools and materials. Having everything on hand will streamline the process and minimize downtime.

• New pull cord (Specific to Cub Cadet SS470 or equivalent size and strength)
• Socket wrench set
• Screwdriver set (Phillips and flathead)
• Pliers
• Work gloves
• Safety glasses
• Lighter or heat source (for sealing the cord end)

Safety Precautions

Prior to starting any repair work on your snowblower, adhere to the following safety precautions to prevent injury:

• Disconnect the spark plug wire: This prevents accidental engine starting during the repair. Locate the spark plug and firmly pull the wire cap off the spark plug.
• Allow the engine to cool: Avoid working on the engine immediately after use to prevent burns. Let the engine cool down completely.
• Wear safety glasses: Protect your eyes from debris that may dislodge during the repair process.
• Wear work gloves: Protect your hands from sharp edges and potential contaminants.

Step-by-Step Replacement Procedure

The following steps outline the process of replacing the pull cord on a Cub Cadet SS470 snowblower. Proceed carefully and consult your owner's manual for specific details related to your model.

1. Accessing the Recoil Starter Assembly

The recoil starter assembly, which houses the pull cord, is typically located on the top or side of the engine. Accessing it generally involves removing a protective cover.

1. Locate the screws or bolts securing the recoil starter cover. These are usually found around the perimeter of the cover.
2. Using the appropriate socket wrench or screwdriver, carefully remove the screws or bolts and set them aside in a safe place.
3. Gently remove the recoil starter cover to expose the recoil starter assembly. Note the orientation of the cover for reinstallation.

2. Removing the Old Pull Cord

Once the recoil starter assembly is accessible, the next step is to remove the remnants of the old pull cord.

1. Inspect the recoil starter pulley: Locate the point where the old pull cord is attached to the pulley. This is typically a knot or a crimped fitting.
2. Release the tension (If Possible): If a portion of the old cord remains, carefully pull it slowly to release any residual tension within the recoil spring. Be cautious, as the spring can unwind quickly and cause injury.
3. Remove the old cord: Using pliers or a screwdriver, carefully untie the knot or remove the crimped fitting securing the old cord to the pulley. If the cord is frayed or broken, you may need to use pliers to extract the remaining piece.
4. Remove the handle: Locate where the cord passes through the handle. Remove any knot or fastener and pull the old cord out of the handle.

3. Installing the New Pull Cord

With the old cord removed, you can now install the new pull cord.

1. Thread the new cord through the handle: Insert one end of the new pull cord through the hole in the handle. Tie a secure knot at the end of the cord within the handle, ensuring it is large enough to prevent the cord from slipping back through the hole.
2. Thread the cord through the recoil housing: Locate the hole in the recoil starter housing where the pull cord exits. Thread the free end of the cord through this hole.
3. Attach the cord to the pulley: Align the hole in the pulley with the hole in the recoil starter housing. Insert the end of the cord through the pulley hole. Tie a secure knot, similar to how the old cord was attached, or use a crimped fitting if that was the original configuration. Ensure the knot is tight and will not slip.

4. Restoring the Recoil Spring Tension

This step is crucial for proper functionality. The recoil spring needs to be properly tensioned to retract the pull cord after use.

1. Hold the pulley: Securely hold the recoil starter pulley in place with one hand.
2. Wind the pulley: With your other hand, rotate the pulley in the direction that winds the recoil spring. This direction will typically be clockwise, but confirm the correct direction by observing how the old cord retracted. Wind the pulley several revolutions (usually 3-5) to create sufficient tension. Avoid over-winding, as this can damage the spring.
3. Test the tension: Carefully release the pulley and observe if the cord retracts smoothly and completely. If the cord retracts too slowly or not at all, add another revolution of tension. If the cord retracts too forcefully, reduce the tension by one revolution.

5. Reassembling the Recoil Starter

Once the recoil spring tension is properly adjusted, you can reassemble the recoil starter assembly.

1. Carefully position the recoil starter assembly: Align the recoil starter assembly with the engine and ensure it sits flush against the mounting surface.
2. Reinstall the cover: Position the recoil starter cover over the assembly, aligning the screw or bolt holes.
3. Secure the cover: Reinstall the screws or bolts that were removed earlier, tightening them securely but not over-tightening.

6. Final Checks and Adjustments

After reassembly, perform final checks and adjustments to ensure proper operation.

1. Test the pull cord: Pull the cord several times to ensure it retracts smoothly and completely.
2. Seal the end of the cord: Use a lighter or heat source to lightly melt the end of the pull cord. This will prevent the cord from fraying. Be careful not to burn yourself or ignite any flammable materials.
3. Reconnect the spark plug wire: Reattach the spark plug wire to the spark plug.
4. Start the engine: Attempt to start the engine to verify that the replacement pull cord is functioning correctly.

Troubleshooting

If you encounter problems after replacing the pull cord, consider the following troubleshooting tips:

• Cord does not retract: Ensure the recoil spring is properly tensioned. Add or reduce tension as needed. Also, check for any obstructions preventing the pulley from rotating freely.
• Engine does not start: Double-check that the spark plug wire is securely connected. Also, ensure that the fuel supply is adequate and the carburetor is functioning properly.
• Cord breaks quickly: Ensure that the cord is not rubbing against any sharp edges or obstructions. Use a high-quality replacement cord that is specifically designed for the application.

Preventative Maintenance

To prolong the life of your pull cord and prevent future replacements, consider the following preventative maintenance tips:

• Avoid pulling the cord to its full extent: Stop pulling just before the cord reaches the end of its travel. This reduces stress on the cord and the recoil spring.
• Store the snowblower in a dry place: Moisture can weaken the cord and cause it to fray.
• Inspect the cord regularly: Look for signs of wear, such as fraying or cracking. Replace the cord if any damage is detected.

By following these instructions and practicing preventative maintenance, you can ensure the reliable operation of your Cub Cadet SS470 snowblower and avoid the inconvenience of a broken pull cord during critical weather conditions.

Conclusion

Replacing the pull cord on a Cub Cadet SS470 is a straightforward repair that can be performed by most homeowners with basic mechanical skills. Doing so ensures your snowblower is ready to operate when you need it most, preventing downtime and potential frustration during winter weather. This proactive maintenance not only saves you money by avoiding professional repair costs but also provides the satisfaction of maintaining your own equipment.
