The hub further includes a locating surface arranged to contact the shoulder when the spindle extends through the central bore. The washer includes an engagement surface contacting the left side face of the blade when the hub extends through the bore of the blade. The engagement surface is disposed a fixed axial distance from the locating surface relative to the length of the hub.
