How to Replace Sewing Machine Belts
- 1). Unplug the sewing machine from the electrical outlet.
- 2). Disengage the hand wheel from the needle driver assembly so that the needle doesn't move up and down as you work to remove the old belt. Usually, this is done by twisting the center knob of the hand wheel. However, methods to do this vary from machine to machine, so you'll need to check your machine owner's manual if you don't already know how to do it.
- 3). Remove the housing over the belt and drive using a screwdriver. Drop the tiny screws in a cup to keep them from rolling onto the floor or otherwise getting lost as you work.
- 4). Study the position of the belt and the placement of the screws holding the motor to the sewing machine. You'll need to remember where each screw belongs, and note the way the belt loops around the working parts of the machine so that you'll reassemble it correctly.
- 5). Unscrew the screws that secure the motor to the sewing machine. When the motor comes loose, move it towards the hand wheel, and remove the slack belt.
- 6). Loop the new belt around the hand wheel, making certain to position it within the guide grooves.
- 7). Loop the opposite end of the belt around the pulley-like cylinder extending from the motor. Again, make sure the belt is positioned within the guide grooves.
- 8). Remount the motor to the sewing machine, adjusting away the slack by positioning the motor further away from the hand wheel, until there's only about a 1/2 inch of slack in the belt. Screw the motor back onto the sewing machine.
- 9). Replace the motor housing by screwing it back into place.
