An attachment assembly for securing large excavation teeth on large earth excavation equipment including an excavation tooth, an adaptor having a tapered nose piece at one end thereof for carrying the tooth and defining means rearwardly of the nose piece for securing the adaptor to the excavation implement, a pin for securing the tooth in place on the nose piece and a wear cap adapted to be carried by an engage the adaptor so as to abut a rear portion of the tooth for reducing wear of the adaptor during use. The wear cap defines a forward tooth abutment surface, a first inclined lower surface adapted to abut a first portion of the adaptor rearwardly of the nose piece, a second inclined lower surface spaced from the first inclined lower surface and adapted to abut a second portion of the adaptor and an opened channel disposed between the first and second inclined surfaces and extending transversely through the wear cap. The channel defines a continuously curvilinear transverse inner wall within the wear cap and is adapted to receive a correspondingly configured transversed rib formed on the adaptor such that upon transversely sliding of the wear cap over the rib, the first and second lower inclined surfaces abut the first and second portions of the adaptor and the forward tooth abutment surface of the wear cap is disposed substantially normal to the tooth. The tooth abutment surface defines a pair of locking projections thereon which are received in a pair of similarly configured channels formed in the base of the excavation tooth to interlock the tooth and wear cap and prevent relative lateral movement therebetween.
