A dragline comprising a main housing, and a moving mechanism for moving the main housing over the ground, the moving mechanism including a drive mechanism mounted on the main housing, an output shaft which extends along an axis and which is driven by the drive mechanism, the output shaft having inner and outer ends, the inner end of the output shaft being spline fit to the drive mechanism such that the drive mechanism causes rotation of the transmission output shaft, a pedestal fixed to the main housing, the pedestal including a leg which has therein a bore centered on the axis, an output pinion mounted on the output shaft intermediate the inner and outer ends thereof for common rotation therewith, and a bearing capsule housed in the bore, the bearing capsule rotatably supporting the outer end of the output shaft, the leg of the pedestal including base and cap portions respectively defining lower and upper halves of the bore, the cap portion being removably fixed to the base portion, such that removal of the cap portion permits the output shaft and the bearing capsule to be lifted from the pedestal after the output shaft is moved outwardly to disengage the inner end of the output shaft from the drive mechanism.
