1. A pin joint assembly, comprising: a pin defining a longitudinal axis and including a first end portion and a second end portion opposite the first end portion; a cylindrical bushing coaxial with the pin about the longitudinal axis and including a first end portion and a second end portion opposite the first end portion; a first collar engaging the first end portion of the pin and including an inner portion in proximal relation to the first end portion of the bushing and an outer portion in distal relation to the first end portion of the bushing; a second collar engaging the second end portion of the pin and including an inner portion in proximal relation to the second end portion of the bushing and an outer portion in distal relation to the second end portion of the bushing; the first end portion of the bushing, the inner portion of the first collar, and the pin cooperating to define a first channel; a first thrust ring coaxial with the pin about the longitudinal axis and residing in the first channel in an axially spaced-apart relation to the bushing; the second end portion of the bushing, the inner portion of the second collar, and the pin cooperating to define a second channel; and a second thrust ring coaxial with the pin about the longitudinal axis and residing in the second channel in an axially spaced-apart relation to the bushing, wherein an outer surface of the bushing cooperates with an outer surface of each of the first and second collars to define an angle ranging from 185° to 190°, such that the first and second end portions of the bushing and the first and second collars are tapered and provide clearance during installation of the pin joint assembly.
