Abstract: A bearing cup has an axis and is formed with an interior surface and an exterior surface. The exterior surface has a first extent and a second extent. A plurality of grooves are formed in the exterior surface of the first extent. Screw threads are formed in the exterior surface of the second extent. An adjusting collar has an axis with an inside diameter formed with screw threads received on the screw threads of the bearing cup. The adjusting collar has an outside diameter essentially equal to the diameter of the major extent. A plurality of grooves are formed in the adjusting collar. The adjusting collar forms an annular thrust surface perpendicular to the axis. The annular thrust surface is axially adjustable with respect to the bearing cup. A locking pin is positioned within aligned grooves in the bearing cup and adjustable collar.
