ABSTRACT:
A track link assembly consists of two parallel arranged chains of links connected end to end, the links of each chain being connected by a joint including a link pin press fit in the bore of the outboard end collar. In order to limit the movement of the collar on the link pin and prevent excessive end play at the seal, a snap ring is fitted on a portion of each end of the link pin which extends outward from the bore of the outboard end collar. One or more protrusions on the outer surface of the boss protect the snap ring from being knocked off during use.
