ABSTRACT:
A pair of sleeves are fixedly mounted in axial alignment on opposite sides of the power plant enclosure of a bulldozer. Rotatably received in each sleeve is a trunnion having at its outer end a yoke holding one of the blade lift cylinders of the bulldozer. The pair of opposed fluid chambers in each lift cylinder are in communication with a pressurized fluid source and drain via passages formed in the respective trunnion and sleeve. For holding the trunnions in position in the respective sleeves against the axial thrust which may be applied thereto in both directions, a stop disc is bolted to the inner end of each trunnion for engagement with one of the sleeves and with a cover bolted to the inner end of each sleeve.
