I need to find the nylon bushing, does anyone know where it is or what he is talking about?

"electric motor is mounted on a crappy sliding assembly which moves left or right depending on which cycle is running, only the flimsy track and tiny nylon bushing was full of crud preventing the motor sliding all the way and tightening the tension on the belt for the spin cycle.
