Poulan 577094601  Hub Pulley Spacer

The purpose of the Spacer is to increase the distance between parts being fastened. Washers are sometimes used, or referred to, as small spacers. Spacers can be made from materials such as brass, stainless steel, nylon, or PVC. Some spacers are unique to the parts they are fastened to, while they may look a lot like those you find in a hardware store, we always suggest purchasing replacement spacers from a genuine OEM original parts dealer, like us, to ensure they fit exactly as intended for safe operation.
