Abstract
An improved articulated pin joint for a track chain used on track laying work machines is provided. The articulated pin joint includes a plug positioned in a central cavity of a track pin. The plug includes an axial passage in which a needle can be inserted to inject grease into the central cavity. The invention facilitates replenishing grease in the field without removing the track chain from the track laying work machine.
