ABSTRACT:
The invention is a ring-like lubrication device used in a pivot joint of the type connecting two members such as on an articulated agricultural tractor or wheeled loader. Such joint has a joint pin and a bearing permitting relative oscillating and articulating movement of the members one to the other. The device includes a hollow, annular reservoir-like chamber which holds lubricant for the joint/bearing sliding surfaces. The device also seals the joint to obstruct the entry of dirt. In a highly preferred arrangement, a device is mounted at the top and bottom of a joint for lubrication and obstruction of dirt entry. The device is configured and arranged to accommodate oscillating and articulating movement between the joined members.
