A method of salvaging a used, damaged turbocharger compressor housing involving the steps of machining the damaged interior surface of the housing, grit blasting the machined surface, building up the machined surface with coating material, and final machining the interior surface to its original specifications. The method includes holding the compressor housing by key datums during the machining steps.

Teeth are normally mounted on the leading edge of a earthworking implement such as a bucket to aid in the penetration of the material being worked. Furthermore, hard material has been applied to selected surfaces of teeth to increase their wear life. However, in many applications the hard material is located on the surface thereof and is subject to impacts which cause the hard material to prematurely chip away. In the subject arrangement, a symmetrical tooth is provided and has a raised lug on the top and bottom thereof each with a groove defined therein and filled with an abrasion resistant material. Since the sides of the tooth on either side of the raised lugs are thinner, they will wear at a quicker rate than the raised lugs having the abrasion resistant material disposed in the respective grooves therein. Consequently, the raised lug increases the strength of the tooth, the abrasion resistant materials in the grooves of the raised lug increases the wear life thereof and improves the sharpness of the tooth during its useful life since the sides of the tooth wear at a faster rate.
