Abstract
A retention assembly, to slidably retain a blade to a support bracket of a grader machine, includes a yoke, a bearing arrangement, and one or more pins. The yoke is adapted to be coupled to the support bracket, and includes a first sidewall, a second sidewall, and a cavity defined therebetween. The first sidewall defines a first thickness and one or more first bores. The second sidewall defines a second thickness and one or more second bores. The second bores are correspondingly co-axial to the first bores. The bearing arrangement is received within the cavity and is adapted to support the blade for a sliding movement of the blade relative to the bearing arrangement. Further, the pins extend correspondingly through at least one of the first bores or the second bores, and into the cavity to engage and retain the bearing arrangement within the cavity.
