Abstract
A side link pusher dog member includes an elongated side link bar with an integral pusher dog extending upward from an upper surface at a leading end and an integral chain pin extending downward from a lower surface thereof. A trailing end has a slot intersected by a transverse recess to receive and position a conventional chain pin. The integral chain pin and rear chain pin have cylindrical portions forming bearing surfaces with a leading and trailing center link respectively and have T-shaped lower ends to receive a conventional side link member to form a complete side link pusher dog assembly. A lubrication passage is formed through the side link bar at a position immediately behind the pusher dog to provide access for a lubricant from a chain pin oiler machine to lubricate the pivot joint formed by the integral chain pin and the leading center link. The rear pivot joint is lubricated by the oiler machine through the slot in the trailing end of the side link bar.
