ABSTRACT:
Each dual wheel assembly on a tractor or trailer system includes outer and inner wheels mounted on a plurality of studs projecting from a hub. The inner wheel is held in place on the studs by a number of flanged cap nuts and the outer wheel is held in place by a number of wheel nuts. When unthreading the wheel nuts to remove the outer wheel, some of the cap nuts invariably remain engaged with the wheel nuts whereas the cap nuts should all remain engaged with the threaded studs during this step. The device disclosed herein is in the form of a ring having a number of hexagonal holes therein corresponding to the number of wheel nuts so that the ring can be placed over those wheel nuts remaining engaged with their cap nuts to prevent rotation of the wheel nuts when each cap nut is individually spun out through the back side of the removed outer wheel. The ring obviates the need for individually holding each wheel nut with a wrench when the cap nut that has remained threadedly engaged therewith is being spun out through the back side of the removed outer wheel.
