Abstract: A fender well press (10) for pressing out the fender well of an automobile which has been damaged as a result of a collision. The fender well press (10) includes an adaptor ring (16) defining a plurality of openings (18) in a manner substantially similar to that of the wheel. A cylinder (22) is secured at one end and extends away from the wheel hub. A second cylinder (28) may be provided to closely encompass the first cylinder (22), the second cylinder (28) selectively pivoting about the first cylinder (22). A mounting plate (40) is carried by the first or second cylinder (22,28) for mounting a piston member (44) thereon. The piston member (44) may be any conventional piston (44) such as an air cylinder. A two-way valve (100) is in fluid communication with the piston member (44) at each end and with a fluid source to control the direction and distance of travel. A fender hammer (88) is secured to the piston shaft ( 74) and is comprised of a mounting block (90) and an engagement member (94).
