ABSTRACT:
A sealed and lubricated pivot pin assembly and method for joining linkage components in earth-moving machinery. The pivot pin assembly includes a pivot pin subassembly, a pair of spacer rings, a pair of track chain type annular seals, an end cap subassembly, and a releasable fastener. The spacer rings simplify joint assembly by setting up and controlling the proper squeeze on the annular seals, preventing crushing of the annular seals during torquing of the releasable fastener, and controlling the set-up length of the assembled joint so that no shimming is required. Each of the pivot pin and end cap subassemblies include an end sleeve which extends beyond the joint clevis or brackets a sufficient distance to allow the pivot pin assembly to float axially and, thereby, compensate for minor deflections in the joint members. The pivot pin assembly is symmetrical in that the pivot pin and end cap subassemblies have common dimensions which permit the pivot pin assembly to be installed from either side of a joint.
