ABSTRACT:
A kit for reaming the governor bores of used motor vehicle transmissions includes several cutting tools having cutting heads of different diameter. The diameters of the cutting heads are matched to the differing diameters of the governor bores of different transmissions. Each of the cutting heads is generally flat and has two pairs of flat parallel edge faces. The edge faces of the two pairs are normal to but do not intersect one another. Cutting tips project outward from the zones between neighboring edge faces. The kit further includes a guide for the cutting tools, and the guide has a centering element as well as several pairs of holes. The holes of different pairs have differing relative positions which correspond to the differing relative positions of threaded holes in the different transmissions. This allows the guide to be connected to any of the transmissions. The kit also includes several adapters each of which is provided with first and second centering elements. The first centering elements are the same for all adapters and are complementary to the centering element of the guide. The second centering elements of the adapters differ from one another and are complementary to differing centering elements of the different transmissions. Each of the adapters is provided with a pair of holes having the same relative position as the threaded holes of the corresponding transmission.
