Abstract
A pivot pin assembly is formed by providing a cylindrical pin portion with a boss at one end. The boss has a flat shoulder surface, so that its periphery is non-circular. A lever arm is provided with a bore that fits over and is complimentary to the boss, and the lever arm is held in place on the boss with a removable threaded fastener that secures the lever arm and the cylindrical pin portion together.
