ABSTRACT:
A boring tool for refinishing the bearing seat of a limited slip differential case having a side opening and having upper and lower bores which are concentric with the bearing seat. Generally frustoconical centering bushings are wedged into the upper and lower bores of the case, and the boring head is inserted into the case through the side opening. Thereafter, a boring bar is slid downwardly through the upper bushing and the boring head and is slid into the lower bushing, the boring head then being secured to the boring bar. When the boring bar is rotated, the bushings hold the boring head in concentric relation with the bearing seat.
