ABSTRACT:
A work machine includes a boom body having a top boom support structure, a bottom boom support structure, a first lateral boom support structure, and a second lateral boom support structure which cooperate with each other to define a boom void therein. The boom body also has a machine frame coupling defined therein. The work machine also includes a coupling subassembly which is positioned within the boom void and attached to the boom body. The coupling subassembly includes (i) a first coupling support structure and a second coupling support structure which are spaced apart from each other so as to define a boss space therebetween and (ii) a boss positioned within the boss space and secured to the first coupling support structure and the second coupling support structure. In addition, (i) the boss has a pin passageway extending therethrough, (ii) the first coupling support structure has a first pin aperture defined therein, (iii) the second coupling support structure has a second pin aperture defined therein, and (iv) the pin passageway, the first pin aperture, and the second pin aperture are aligned with each other. The work machine further includes (i) a work machine stick which is pivotably coupled to the coupling subassembly and (ii) a work machine frame coupled to the machine frame coupling of the boom body.
