How To Change Sewing Machine Belt – The Easy Way

Understanding Sewing Machine Belts

It may appear to be a simple component, but sewing machine belts come in all shapes and sizes, and each one has its own set of advantages. There are both gear belts and non-geared belts to accommodate your equipment. ‘ For motor pulleys that have toothed wheels, you’ll want to use the geared version instead.

Types Of Non-Geared Belts

There are V-belts and circular belts for non-geared belts. The V-belts work well because they can slide into the pulley’s groove. Unlike geared belts, which cannot be used on wheels with teeth, lug belts have a toothed inner surface.

Precautions For Changing A Geared Belt

The geared belt, as you are aware, is built to fit your machine. There’s no room for tinkering here. To avoid having your needle go out of phase, make sure it’s fitted correctly before using it.

Finding The Right Non-Geared Belt For Your Machine

You can find the right non-geared belt for any model from the many sewing-related websites out there. As an alternative, if your machine does not have an appropriate belt, there is an option to determine the exact measurements.

It’s simple to remove the belt if it’s not within the machine. The first step is to center your machine in the slots if the motor can be modified.

Wrap the twine around the handle wheel in the same way as the belt is wrapped around the handle wheel. To wrap the rope around the pulley, connect the motor to it. Connect the two ends with a pen and mark the spot.

As a general rule, new belts tend to relax slightly, so you should make the belt as tight as you can. Your belt will fit perfectly if you cut your string at the area you’ve marked.

Removing Your Worn-Out Belt

Removing the belt should be done with caution. The first step is to remove the electrical plug from the socket. Make sure that your handwheel is always adjusted down as well. When you remove the belt, the needle will not turn.

To remove the screws holding the motor in place, you first need to remove them from the machine’s backside. It’s therefore a cinch to remove the belt from the pulley.

Installing The New Belt In Your Machine

Fixing the handwheel’s handwheel is the first step. Spin the handwheel in order to correct it. While feeding the belt, progressively reverse the wheel rotation. Keep in mind the outside edge of your belt as you are feeding the belt.

It’s easy to tell because of the marks on most belts. Make a slow, deliberate motion with the handwheel, allowing the belt to be fed into place. After that, lower it to the motor’s pulleys.

Completing The Installation Process

The motor can be returned to its original position, with the belt tightest, after installation of the new belt. If the motor’s location can be altered, this is conceivable. This prevents the belt from slipping out of place later on, which is a common problem with pre-tensioned belts.

Using the screws that hold the motor’s housing in place is an absolute necessity. After you’ve finished tightening the screws, take a look at the belt’s slack. The belt should not have more than a half-inch of slack in it.


A sewing machine’s belt can be replaced without the assistance of a professional mechanic, however reading the instruction manual thoroughly is recommended before commencing. You need to know exactly what kind of belt you’ll need before you buy it.

If you already have a geared belt, make sure you get the same size. In most belts, the numbering is listed on the inside. If your sewing machine’s belt begins to show signs of wear, consult the handbook for instructions on how to replace it.
