ABSTRACT:
Eyes in adjacent track segments in a bulldozer type track are secured to each other by a pin which is provided with a grease fitting and connecting passages for communicating lubricant to the bearing surfaces in the linkage. The pins are housed in a metal sleeve which cooperates with resilient seals to retain the lubricant in the linkage and to keep external matter away from the linkage bearing surfaces. The pin is held in place by removable retaining means so that the linkage may be separated and reattached without special equipment.
