How To Change Sewing Machine Belt

Surface Inspection

The first step to change a sewing machine belt is to inspect the surface of the machine and make sure it is in good working order. Look for any visible damages and tears that can be easily visible. Make sure the belt is on correctly and that the tensioner is in the right position. If the tensioner is not in the right position, then it can lead to the belt slipping off or not functioning properly. In addition to inspecting the surface, check the tension spring to make sure it is not worn or broken. This can cause major problems with the belt, and it should be fixed before continuing with the process.

Removal of Existing Belt

The next step in the process is to remove the existing belt. This can be done by loosening up the tension and removing the belt from the machine. It is important to note that if the belt is too tight, you may need to use a pair of pliers to loosen it up. Once the old belt has been removed, inspect the area to make sure there are no sharp edges that may damage the new belt. This can be easily avoided with a quick visual inspection.

Installation of New Belt

The next step is to install the new belt on the machine. It is important to note that if you have a belt that is too long, you may need to trim off any excess materials to ensure a proper fit. Before installing the new belt, place the tensioner in the proper position and then loop the belt around the machine’s drive system. Once it is securely in place, check that the tension is right and the belt is properly positioned.

Tension Adjustment

The next step is to adjust the tension on the belt. This can be done by turning the tensioner counter-clockwise and applying pressure to the belt. Then, adjusting the tension of the belt until it runs smoothly and is not too tight or loose. During this process, you should check the tension several times to make sure the belt is operating properly.

Safety Measures

When changing a sewing machine belt it is always important to consider safety. Make sure to always wear protective gear, such as gloves, to prevent any cuts. Also, be mindful of where the belt is in relation to your body, as it can cause serious injuries if it is not properly handled.


Regularly maintaining the belt on a sewing machine is essential for ensuring its longevity. This can be done by inspecting the belt for any weak spots or damages and checking the tension. It is also important to note that some belts may require regular lubrication to keep them in optimal condition.


If the sewing machine belt is not functioning properly, the first step to troubleshoot is to check the tension. If the tension is too tight, adjust it until the belt runs smoothly. If this doesn’t solve the issue, inspect the belt for any damages or wear and tear. Replace the belt if it is beyond repair.

Choosing the Right Belt

When choosing the right belt for a sewing machine, the size, material and the type of stitching will all play a factor in its selection. Different belts can last different amounts of time, so it is important to choose one that is the correct size and is durable enough for the task at hand.

Correct Threading Technique

Having the correct threading technique is essential when replacing a belt on a sewing machine. The threads should be kept tidy and pay close attention to the way the threads are threaded through the stitch plates. This will ensure the belt tensions correctly and that the stitches are even.

Belt Installation Tools

In order to properly install a belt on a sewing machine, you may want to invest in several tools. These include a belt tensioner, screwdriver, pliers, needle nose pliers and a measuring tape. Having the right tools can help make the process much easier and you will have peace of mind knowing that you are equipped to change a belt without causing any damage to the machine or yourself.

Saving Time and Money

When it comes to saving time and money, having the right tools and knowing how to properly install a belt on a sewing machine can be a great asset. Replacing the belt regularly can help prevent any major problems down the line and keep the sewing machine running efficiently. Additionally, investing in the proper tools and having an understanding of how to properly change the belt can help you save time and money.
