Review on SINGER 2125 Sewing Machine Winding by Amber Perez

Said to fit most machines with belts but nothing special as to specifics. It says 3 inches by 5 inches, but that's the size of the blister pack it comes in, so it's not useful at all. It's a rubber elastic belt so I was able to fit it to the car but it's a little tight and because it's rubbing against the sides of the flywheel there's too much drag and the engine has trouble turning over if it even starts. I suspect that's why there are so many reports of it failing quickly because it's running on a more modern, more powerful motor and wearing out quickly. It measures approximately 13.5 inches. So if your car requires a belt of this size it might be worth a try as it is so cheap and looks like it will hold up in a car with the right fit. It's probably best to buy a belt whose specs list your model. the '66 uses a 15 3/8" V-belt (not round) that I found at another vendor.
