ABSTRACT A pulley has a planar end wall and an annular wall extending axially outwardly therefrom. The annular wall is formed with belt receiving grooves and the end wall is formed with a central opening for mounting the pulley on a hub or shaft. A stamped sheet metal washer having a generally annular configuration is formed with a central hole and an integral projection extending radially outwardly from the outer edge of the washer. The washer is firmly attached to the end wall of the pulley preferably by welding or by bonding with an acrylic structural adhesive with the central hole of the washer being concentric to the central opening of the end wall. The projection is positioned to counterbalance any unbalance in the annular wall that may have developed therein during forming of the pulley.
