ABSTRACT:
An improved ratcheting tool has a driven shank rotatably supported fore and aft in the ratchet housing. A reduced-diameter rearwardly-extending portion of the driven shank passes through a central recess in a pivotable cam shifter and is rotatably piloted in a closed cylindrical recess. This recess is formed in the ratchet housing rearwardly of a blind axial bore within which the driven shank is disposed. An intermediate portion of the driven shank is rotatably journaled in the inner annular bearing surface of a collar; and the collar is press-fitted within a counterbore forwardly of a ratchet on the driven shank, thereby retaining the driven shank in the ratchet housing.
