I am trying to replace by idler pulley. According to the diagram, there is just the bolt, the curved washer, the pulley, the regular washer and the nut underneath. However, look at the pic, it is tilted and seems like it needs a space or something. The diagram does not show one. Anyone know if that is all I am missing? It is the pulley in the back that is tilted. Thanks!
