ABSTRACT:
The invention is concerned with a pivot joint having means for indicating wear thereof. The pivot joint comprises a headed pin, a socket in which the head is engaged and from which the pin projects, mating bearing surfaces on the head and the socket such that the pin is movable angularly with respect to the socket, a wear indicator extending through an aperture in the sockets and having its inner end engageable with the head, and a diaphragm which extends between the indicator and the socket to seal the bearing surfaces against ingress of foreign matter through the aperture.
