Abstract: A tool for installing a retrofit bearing having a length that extends beyond the original location of a tapered sleeve used to secure an original bearing and a method of performing the installation provide a reliable way to replace an engine bearing that supports and extends within a shaft end. The tool includes a flange with holes matching the engine block, a body coupled to the flange for accepting the captive portion of the replacement bearing, and a tapered sleeve disposed within the tool body for compressing a wire lock engaged with a mating channel of the replacement bearing when the captive portion is in the tool. The tapered sleeve has a diameter that mates with an inside diameter of an end of the engine shaft, so that the wire lock remains compressed until it engages with the channel provided in the engine shaft for the original snap ring.

Abstract: A combination tool for machining a bore has a tool shaft transmitting a rotational movement and an oscillating movement in an axial direction of a bore to be machined with the tool. A horning tool is arranged on the tool shaft, and a deburring tool is arranged on the tool shaft at an axial spacing to the honing tool in a direction of a longitudinal axis of the tool shaft. The honing tool is configured to move for each honing stroke between a lower position and an upper position wherein a spacing between a lower edge of the honing tool and a lower edge of the deburring tool in the direction of the longitudinal axis of the tool is greater than a spacing of the lower edge of the honing tool to a workpiece surface when the honing tool is in the lower position.

Abstract: A plastic housing has a front shell with inwardly protruding bristles of an exterior wire brush, and a rear shell which retractably receives the outwardly protruding bristles of an interior wire brush. The interior brush is mounted to a shaft which engages the housing, and which is driven by a motor, such as by a power drill. A ring-like deburring element is mounted to the shell between the front shell and the rear shell, and has an inwardly and frontwardly protruding generally frustoconical first wall forming a deburring element which defines a central opening through which the interior brush may be projected and retracted. The first wall may be planar segments, or may have a circular cross section. The deburring element serves to position a pipe for burnishing by the exterior brush, and also deburrs the end of the inserted pipe.

Abstract: An element-doped diamond crystal is disclosed herein. The crystal includes at least one dopant element which has a greater concentration toward or near an outermost surface of the crystal than in the center of the crystal. The concentration of the dopant element is at a local minimum at least about 5 micrometers below the surface. The concentration-profile of the dopant element for these diamond crystals causes an expansion of the diamond lattice, thereby generating tangential compressive stresses at the surface of the diamond crystal. These stresses beneficially increase the compressive fracture strength of the diamond.

Abstract: A tube cleaning device having a pair of jaws pivotally mounted on a frame and having opposed abrading surfaces defining an abrasion cavity, a mandrel fixed to the frame and extending axially thru the cavity for slidably receiving a tube end to be cleaned, spring structure forcing the abrading surfaces toward each other and laterally toward the mandrel, and a rotator knob on the frame for rotating the device in either direction around a tube end positioned on the mandrel.

Abstract: A honing tool comprises an hexagonally shaped mandrel having a cylindrical bore extending centrally therethrough. Six similar tool holders are each provided with a pair of spaced cylindrical gear racks having rack gear teeth formed thereon and integrally attached to an elongate tool support. A metal tool carrier to which is suitably bonded a tool, such as an abrasive cutting stone or a wiper is removably attached to a respective tool support by a clamp screw. The gear racks of each tool holder are slidably mounted in respective bearings holes in the mandrel. Gear teeth on the racks mesh with gear teeth formed on a splined shaft rotatably mounted in the mandrel bore. Thus, rotation of the shaft counterclockwise relative to the mandrel extend all of the tools outwardly to extended positions.
