How To Replace Tension Spring On Singer Sewing Machine

If you want to repair a Singer sewing machine, one of the components that may need to be replaced is the tension spring. Knowing how to replace the tension spring yourself can save you the cost of having a professional do the job. Without proper tension, the fabric won’t stitch properly and may cause damage to the material. The tension in the spring of a sewing machine works by regulating sewing tension according to the fabric and thread being used. The spring itself is a small metal or steel rod that is connected to metal arms and has a wire attached.

Fortunately, replacing the tension spring is a job that anyone with minimal sewing experience can do. The most important tool you will need is a small Phillip’s screwdriver, some wirecutters and a pair of needle-nose pliers. If the tension spring has become rusty or misaligned somehow, you may need to use some sandpaper or a polishing cloth to get it back in shape.

The first thing you need to do is to make sure that your machine is unplugged and all of the threads have been removed. Next, you need to locate the tension spring on the machine. It is usually located directly behind the bobbin case. You may need to consult a Singer sewing machine manual to find out exactly where it is located.

Once you have located the spring, use your screwdriver to remove any screws that are holding it in place. Be careful when removing the screws, as the tension spring may suddenly spring out when the last screw is taken out. Take your time and make sure that you don’t lose any of the screws along the way.

Once the spring has been removed, you can use your wirecutters to cut the wire attached to the spring and then use the needle-nose pliers to bend the ends of the wire so that they don’t touch each other. Once you have done this, you can use the pliers to remove any extra bits of wire.

Now you can replace the tension spring by inserting the new spring into the slots and replacing the screws. Make sure that the spring is properly seated in the slots before you tighten the screws.

Once the spring is replaced, you can use the needle-nose pliers to attach the wire back to the spring. Then, use the screwdriver to carefully tighten the screws so that the spring is secure. You may need to adjust the tension on the spring according to your specific sewing needs.

Factors to Consider When Replacing Tension Spring

When you are replacing the tension spring on your Singer sewing machine, it is important to take into consideration a few important factors. For example, if the spring is too weak or too strong, it may lead to fabric bunching or skipped stitches. You may need to adjust the tension on the spring to achieve the right tension. Additionally, if the spring is not installed correctly, it can cause damage to the machine. That is why it is important to make sure that the spring is properly installed and tensioned.

Importance of Regular Tension Spring Maintenance

Regular maintenance and tuning of your machine is key to ensuring that it runs smoothly. This includes taking the time to inspect, clean and lubricate the machine on a regular basis. Additionally, it is recommended that you check your tension spring on a regular basis and replace it if it is worn or damaged. This will ensure that the machine runs efficiently and that you can achieve the best sewing results.

Types of Tension Springs Available

There are several types of tension springs available for Singer machines and other brands. Depending on the model of the machine, you may need a specific type of spring. Different models will require different types of springs, so it is important to consult the manual or contact a professional before purchasing a new spring.

Alternative Options for Replacing Tension Spring

If you don’t feel comfortable replacing the tension spring yourself, there are some alternative options available. You can take the machine to a professional sewing machine repair shop and have them do the job. Additionally, there are some places that offer needle threader and other replacement parts for Singer machines.

How to Find a Replacement Tension Spring

Replacement tension springs can be found online, in sewing machine shops, or through Singer. It is important to make sure that you find a spring that is the same as the one you are replacing, as different models may require different types of spring. Additionally, it is important to make sure that the spring is made of high quality materials to ensure that it lasts longer.

Understanding How the Tension Spring Works

Knowing how the tension spring works can help you troubleshoot any issues that you may have when replacing it. The tension spring works by manipulating the tension on the sewing machine according to the fabric and thread being used. The spring works by constricting to control the tension on the needle and thread. By understanding how the spring works, you can ensure that it is installed correctly and tensioned properly.


Replacing the tension spring on a Singer sewing machine is a relatively easy task. However, it is important to make sure that you have the right tools, the correct replacement spring and understand the mechanics of the tension spring. Taking the time to inspect the tension spring on a regular basis and replacing it when necessary will help ensure that your sewing machine runs smoothly and produces great results.
