Abstract
A torsion bar disk gang mounting assembly includes a shaft pivotally suspended from a disk frame. A rectangular tube receives a portion of the shaft. A pair of disk gang support arms are pivotally coupled to the shaft and extend generally rearwardly therefrom. The arms are fixed to opposite ends of the tube and support a disk gang at their distal ends. A torsion bar is resiliently coupled between the tube and the shaft to bias the disk gang downwardly. A method of making such a disk gang mounting assembly includes the steps of assembling the shaft, tube and torsion bar, then fixing the arms to ends of the tube. The shaft is then pivoted with respect to the tube and arms to establish a predetermined preload in the torsion bar. A stop arm is then fixed to the shaft in engagement with an abutment on one of the arms to maintain the preload in the torsion bar and to limit downward movement of the disk gang. Coupling holes are then drilled in the ends of the shaft with a certain orientation with respect to the arms so that consecutive shafts may be coupled together with coupling collars.
