Pulley Lock nut, replaces 137266 and 139729. Very important......When installing the pulley the spacer (thick washer like item) must go under the pulley (between the pulley and top bearing). Installing the spacer on top of the pulley or not using a spacer will result in damage to the splines on the shaft and pulley.
