Abstract
A preloaded pivot joint subject to wear in normal use has a protuberance on its internal movable bearing seat which protrudes through the pivot joint cover. As the joint wears, the degree of protrusion progressively diminishes. Indicia are provided on the protrusion and cover cooperatively to identify to the observer whether wear justifying replacement does or does not exist. Wear giving rise to loss in preload sufficient to warrant replacement of the pivot joint is indicated when the top surface of the protuberance recedes to a position having a predetermined observable relationship with the top surface of the cover. The elastomeric ring which provides the preload also provides a seal for an internal grease chamber which is accessible from a fitting in the protuberance.
