ABSTRACT:
A pulling tool including a first pulling member which is essentially a rectangular-shaped flat bar of heavy metal having a pair of holes formed in it in spaced apart relationship. Affixed to one face of this flat bar is a pulling bar which likewise is a heavy metal material and which has a hole in it whereby a hydraulic jack or the like can be attached to the first pulling member. The pulling tool also includes a second generally U-shaped pulling member having a straight portion and a pair of legs which are spaced apart a distance corresponding to the distance between the two holes in the flat bar of the first pulling member, and a handle. In accordance with one embodiment of the invention, both of the pair of legs are threaded to receive a threaded nut, with the first and second pulling members being affixed together by extending the two legs of the second pulling member through the two apertures in the first pulling member, and then threadedly affixing the nuts on the legs.
