ABSTRACT:
The present invention relates to an improved king pin pressing tool. The tool comprises a three-sided structure forming a chamber having two openings therein, one opening in the top of the structure with a second opening in the back side thereof. The first opening receives a portion of an I-beam and acts to secure the tool against the I-beam during the pressing operation. The second opening in the top of the structure is adapted to receive the king pin as it is pressed out of the I-beam. The chamber that is formed by the three-sided structure is adapted to receive the hydraulic jack that is utilized in pressing the king pin out of the I-beam.
