Abstract
A retention assembly to slidably retain a blade to a support bracket of a grader machine. The retention assembly includes a yoke adapted to be coupled to the support bracket, and the yoke includes a base wall, a first sidewall extending directly from the base wall, the first sidewall being configured to face the blade, and a second sidewall extending directly from the base wall, the second sidewall configured to face away from the blade and spaced apart from the first sidewall to define a cavity therebetween, along with the base wall. A retainer extends from at least one of the first sidewall, the second sidewall, and the base, and a bearing arrangement is received within the cavity and adapted to support the blade for sliding movement of the blade relative to the bearing arrangement. The retainer engages the bearing arrangement and retains the bearing arrangement within the cavity.
