Abstract

An improved excavating tooth and wear cap assembly is provided in which the front pin that interconnects the replaceable point to the adapter nose is protected from undesirable deformation by interlocking stabilizing lugs and grooves formed respectively on the wear cap and adapter base portions of the assembly. The cooperation between these lugs and grooves prevents earth forces from driving the wear cap portion of the assembly forwardly along the adapter base into the point and thereby causing the point to deform the connecting pin. Field installation of a lower wear cap portion of the assembly is facilitated by the provision of cooperating support lugs on the wear cap and shoulders on the adapter which, together with a pivotal interconnection between the adapter and wear cap, permits the lower wear cap to be hung from the adapter in a temporary support position until the point can be installed and interconnected to the wear cap to complete the assembly.
