ABSTRACT:
A window operator has a base with an upstanding pivot pin having a bushing thereon and at least one component pivotally mounted on the bushing. The components are held in assembled relation by a captured washer and the washer has an outer annular portion formed to provide a controlled clearance. A method of forming the window operator comprises assembly of the pivot pin, bushing and pivotal component to a mounting base and the capturing of a washer beneath the head of the pivot pin and with an inner annular part of the washer engaging an upper edge of the bushing which extends beyond the upper surface of the pivotal component, followed by a deformation of the outer annular part of the washer to compress the pivotal component between the washer and the base followed by release of the compressive force to permit spring-back of the outer annular part of the washer to provide the controlled clearance.
