Toothed balance wheel belt. To select the correct belt size-measure your current belt by folding it in half. Double the distance from inside one end to the inside edge of the other. Or wrap a string around the drive pulleys of your machine and measure the string length.
Some belts have a number on the outside such as 1934 which means it is a 19-3/4" belt.
