It should loop around the roller, Rachelle, then twist one-quarter turn to hook over the motor shaft (the steel one that points straight down). Now, it CAN be hooked over the motor shaft in either of two directions, depending upon which direction you twist it - one way will make the roller run backwards and probably pop the belt back off the shaft. The other way is the correct way - if the roller rotates the correct direction when you bump the power switch, then it's on correctly.
