Abstract
A fifth wheel assembly for tractors or other draft arrangement has a bearing plate with a lubricating plate, a peripheral wall with diametrically opposed notches extending above the bearing plate surface and a nonmetallic lubricating wear liner with diametrically opposed ears notchable with the notches to resist rotational motion by the liner, which liner extends above the peripheral wall and is secured against the bearing plate as a lubricating liner but retained within the bearing plate cavity against radially outward displacement by the peripheral wall.
