Abstract
A lock that includes a pin and a collar. At least one of the pin and collar include a circular seal and a recess to store the seal. When the pin and collar are engaged in a locking manner, the surfaces of the pin and collar compress the seal such that a barrier is formed to limit ingress of fine earthen material. The lock assembly may be a component of a wear assembly. The lock assembly may be positioned into aligned holes to capture components of the wear assembly together, e.g. a point to an adapter or an adapter to a base. The recess of the pin may be located adjacent the head of the pin. The recess of collar may be located near the bottom of the collar. The application of both an upper and lower seal can further limit the ingress of fine earthen material.
