Abstract: An improved vertical service door for a tractor engine housing of the vertically-hinged horizontally swingable type. The vertical service door has a lower panel hinged to the lower edge of an upper panel, and means to support the lower panel in a horizontal position when the door is open so that it may serve as a tool tray during engine service. Some preferred embodiments include an inwardly-turned edge forming a vertical retaining edge for the tray and a rod/J-slot linkage between the upper and lower panels to support the lower panel in its horizontal position.

Abstract: A bushing assembly is disclosed for effecting a pivotal connection of associated first and second members. Notably, the assembly is of an integrally sealed configuration, and includes concentrically arranged first outer and second inner bushings which are sealed by a pair of annular end caps. An arrangement is provided for conveniently lubricating the interface thus formed between the inner and outer bushings, with the sealed nature of the construction significantly reducing the required maintenance. Notably, final assembly of the pivotal connection provided is effected with a suitable adhesive, thus permitting manual or hand-fitting of the various components for final assembly.
