Abstract: The present invention provides a wear plate 20 for assembly to a base 50 which is adapted to be mounted to an implement, the wear plate 20 having an upper body portion and two side portions 22,23 extending downwardly therefrom, the side portions 22,23 having from their inwardly facing surfaces at least one inwardly projecting flange formation 36,37,38,39. The present invention also provides a base member 50 for receiving a wear plate 20, the base member having a body for attachment to an implement to be covered by a wear assembly, the body having on two opposed sides, at least one flange formation 46,47,48,49 extending away from the body. The present invention further provides a wear component assembly have having a wear plate as previously described, and a base member as previously described, characterised that the wear plate 20 will assemble into the base 50 in one direction and the shape formations 46,47,48,49 on the base 50 and the plate 20 will ensure that, once the wear plate 20 has been moved to the limit of its travel with respect to the base 50, then the wear plate 20 will overly or cover the base 50. The present invention also provides an assembly of wear components 20,50 wherein a line of bases 50 are secured to an implement to be protected so that once secured a respective number of wear plates 20 can be assembled in sequence from one end to another along the line of the bases so that each new wear plate 20 will prevent the preceding wear plate 20 from moving to a disassembly position with the final wear plate 20 in the line being prevented from moving in a disassembly direction by means of an abutment member 71,100,300 placed at the end of the assembled line to the implement or to the last base 50 in that line. The present invention further provides a method of assembling wear components 20,50 wherein a line of bases 50 are secured to an implement to be protected so that once secured a respective number of wear plates 20 can be assembled in sequence from one end to another along the line of the bases 50 so that each wear plate 20 will prevent the preceding wear plate 20 from moving in a disassembly direction with the final wear plate 20 in the line being prevented from moving in a disassembly direction by means of an abutment member 71,100,300 placed at the end of the assembled line to the implement or to the last base 50 in that line. The present invention also provides an abutment wear assembly 100,300 including a wear member 100 to be mounted to an implement or apparatus to be protected, a base member 300 to be attached to the implement or apparatus, a lock member 121 to lock the wear member 100 to the base member 300, the wear member 100 including or receiving the lock member 121 and the base 300 including at least one aperture 34 in which is located a releasable retaining means 140 to releasably hold a portion of the lock member 121. The present invention further provides a base 300 for an abutment wear assembly for use with an implement or apparatus, the base 300 including at least one formation 33 to cooperate with a wear member 100 which is to be secured to the implement or apparatus, the base 300 being adapted to be secured to the implement and characterised in that the base 300 includes an aperture 33 to receive a spigot or shaft of a lock member 121, the base 300 including a retaining means passage 34 which will allow a retaining means 140 to be positioned in the passage 34, in alignment with the aperture 33, and which will engage the spigot or shaft 121. The implement or apparatus can be one of: an excavation bucket; a grader blade; a chute; an excavation bucket edge; an excavation bucket surface; dump or haul truck load carrier; a mill; an earth, ore or mineral handling apparatus. 21 46.1 46 44 22 3838.1 4 36 36.1 4b 5 39.1 41FIG 3
