ABSTRACT:
A conduit arrangement for a tilt cylinder of a bulldozer having a track frame and a push arm connected to the track frame for operating the blade of the bulldozer and including a trunnion for pivotally connecting the push arm to the track frame. A pair of spaced fluid passages are provided through the trunnion. A first pair of conduits have one end coupled to the tilt cylinder and the other end connected to the fluid passages. The first pair of conduits pass through an internal bore provided through the push arm. The inboard end of the trunnion extends into the interior of the track frame. The fluid passages extend through the trunnion into the interior of the track frame. A second pair of conduits pass inwardly through the track frame towards the main frame of the bulldozer. One end of each of the second pair of conduits is connected to the fluid passages and the other end extends into the bulldozer main frame. The track frame is spaced from the bulldozer main frame. A flexibly supported, generally hollow coupling spans the space between the main frame and the track frame, and defines a protective housing for the second pair of conduits passing therethrough. A hydraulic control valve is connected to the other end of each of the second pair of conduits for controlling the flow of fluid through the first and second pair of conduits to and from the tilt cylinder.
