Abstract
A retention assembly for a jack is disclosed. The retention assembly includes a housing, a bushing, a shaft, a gear, a pin, and a spring. The housing includes a housing aperture, into which the bushing is positioned. The shaft, which includes a shaft aperture, extends through the bushing such that the portion of the shaft defining the shaft aperture is positioned within the housing. The gear, which includes a gear aperture, is positioned on the shaft such that the gear and shaft apertures align to accommodate the pin. The spring is positioned on the shaft and within the housing such that a first end of the spring applies a force to the bushing to retain the bushing in the housing aperture and a second end of the spring engages the pin to retain the pin within the shaft and gear apertures.
