Abstract
A compact, torque multiplying apparatus for turning nuts of wheel lugs has an orbiting gear arrangement including an epicycling gear element driven within a housing by a socket wrench. In one case, the housing is held fixed by a tool that mates with adjacent wheel rim contours and output torque is applied to a lug nut by rotation of a second gear element. In another case, the second gear element is held fixed by keying it to the end of the lug, and output torque is transmitted to the nut by the housing.
