Abstract
A pin for a coupler assembly for rotatably coupling a beam of a circle assembly of a grader machine with a bracket of a moldboard assembly of the grader machine includes a body defining a head portion and a shank portion. The shank portion integrally extends from the head portion. The head portion is adapted to be seated over one or more of the beam and the bracket. The shank portion is adapted to pass through the beam and the bracket to rotatably couple the beam and the bracket about the shank portion. A grease gallery is defined through the head portion, extending into the shank portion. The body defines multiple grease passages branching out from the grease gallery up to corresponding sections of an outer surface of the shank portion where the beam and the bracket are correspondingly adapted to lie in rotatable registration with the shank portion.
