ABSTRACT:
A device for straightening out a vehicle wheel rim includes a ram and a hydraulic pump for manually operating the ram. Opposing pressure members are on located at opposite ends of the ram, and two semi-spherical contact members are contacted by the pressure members. In use, the semi-spherical contact members are fittable within a vehicle wheel rim for straightening a bent portion of the rim. The method is preferably performed with heating of the rim. Accordingly, the present invention provides a number of advantages which were not before possible with existing methods, including that the device can be completely portable, that the device does not require electricity nor other power source to operate, that it takes little training or expertise to operate, that it is relatively inexpensive to manufacture, and that it takes much less time than the currently used methods.
