Abstract
A tool for removing the axle shaft from a wheel hub includes a ram and guide assembly that makes the job quick, easy, and safe. Two threaded adaptors connect the guide brace to the wheel's lug studs. A sliding ram, guided by the brace, transmits the blow of a sledge hammer squarely against the center of the axle shaft. The solid impact releases the force that tightly binds the axle shaft to the wheel's lug studs. The ram is made of a relatively soft mild steel to prevent damage to the axle shaft.
Claims14
A shaft remover to be used in conjunction with a hammer for removing an axle shaft from a hub, said hub having two threaded lug studs that engage a flange at one end of said axle shaft, said flange having an outside diameter greater than a bore diameter of said hub, said shaft remover comprising:
- two adaptors having internal threads for screwing onto said two threaded lug studs;
- a brace adapted to attach to said two adaptors, said brace having a guide hole in substantially collinear alignment with a longitudinal center line of said axle shaft when said brace is attached to said two adaptors with said two adaptors being screwed onto said two threaded lug studs;
- and
- a ram adapted to slide longitudinally within said guide hole, said ram having one end adapted to abut said one end of said axle shaft having said flange, said ram having an opposite end adapted to be struck by said hammer, whereby upon striking said ram most of the impact force delivered by said hammer is transmitted to said axle shaft to partially release a force binding said flange to said lug studs.
A shaft remover to be used in conjunction with a hammer for removing an axle shaft from a hub adapted to hold a tire thereon, said hub having two threaded lug studs that engage a flange at one end of said axle shaft, said flange having an outside diameter greater than a bore diameter of said hub, said shaft remover comprising:
- two adaptors each having 5/8-18 internal threads for screwing onto said plurality of threaded lug studs, said adaptors each further having external threads;
- a brace adapted for fastening to said two adaptors by way of said external threads, said brace having a guide hole in substantially collinear alignment with a longitudinal center line of said axle shaft when said brace is fastened to said two adaptors and said two adaptors are screwed onto said two threaded lug studs;
- and
- a ram adapted to slide longitudinally with said guide hole, said ram having one end adapted to abut said one end of said axle shaft having said flange, and said ram having an opposite end adapted to be struck by said hammer so that upon striking said ram most of the impact force delivered by said hammer is transmitted to said axle shaft to partially release a force binding said flange to said lug studs.
A method of removing an axle shaft from a hub, said hub having two threaded lug studs that engage a flange integrally joined to one end of said axle shaft, said flange having an outside diameter greater than a bore diameter of said hub, said method comprising the steps of:
- screwing two adaptors to said two threaded lug studs, said two adaptors each having internal threads at one end and external threads at an opposite end;
- fastening a brace to said two adaptors by way of said external threads, said brace having a guide hole such that, when said brace is fastened in place, said guide hole is substantially in collinear alignment with the longitudinal center line of said axle shaft;
- striking a ram situated within said guide hole, said ram having one end adapted to abut said one end of said axle shaft having said flange, and said ram having an opposite end adapted to be struck;
- disconnecting said brace from said two adaptors;
- unscrewing said two adaptors from said two threaded studs;
- and
- axially pulling said axle shaft out from within said hub.
