ABSTRACT:
A bushing and wear protector that is releasably received within the socket of a bracket to rotatably mount a wear tooth on a roadway surface cutting machine. The bracket includes a socket for normally receiving the shank of a wear tooth. The present bushing and wear protector includes a spring sleeve for encircling the tooth shank for rotatably securing the tooth within the bracket socket. The tooth is held firmly in axial position in relation to the bracket but will facilitate rotary movement of the tooth therein. The bushing and wear protector also includes integral shoulder and flange provisions to cover and protect exposed surfaces of the bracket to avoid wear by impact and abrasion with roadway material, and from abrasion and impact from the wear tooth itself. The protector will wear at approximately the same rate as the tooth so both can be replaced at normal tooth replacement intervals. The covered surfaces of the bracket, will be protected by the new bushing and wear protector provided with each change of wear teeth.
