This invention relates generally to a method for repairing a casting, and more specifically to a method of repairing a casting by pouring melted filler material into a damaged portion of the original casting. Damaged cast metal components, such as a cylinder head of an internal combustion engine are repaired by preheating the component to a first preheat temperature. The damaged area of the casting is then heated to a higher temperature using a torch and melted filler material is poured into the casting. The torch is used to maintain the temperature of the melted material for thirty seconds to two minutes. The temperature of the filler material is then cooled using compressed air.

An improved tool for pulling off a rotor of a motor from a shaft or a fan from a shaft, which improved tool is provided with hooked arms that are releasably but securely held at one end in the housing, without the use of retaining clips, so that the arms do not fall off during use or become lost, and so that they do not interfere with the use of the tool when using the securing bolts for pulling off a rotor. The housing of the improved tool of the invention is circular in shape, and in a first version , is provided with a plurality of equally-spaced holes about its circumference, which holes received the hooked ends of the hooked arms, so that various configurations of hooked arms may be provided to best suit the configuration of vanes and type of fan being pulled off a shaft. In another version, instead of the plurality of equally-spaced holes for holding the hooked ends of the hooked arms, an annular groove is provided on the upper, horizontal surface of the lower circular cross-sectioned section of the housing, which annular groove is preferably continuous for 360 degrees about the upper, horizontal surface of the lower circular cross-sectioned section of the housing, whereby there is provided substantially an infinite spacing capability to the hooked ends of the hooked arms. .

The invention is a mill rod puller which removes mill rods from hammermills or similar devices through the use of a reciprocating hydraulic action. The rod puller includes a support frame and a rod extension that attaches to an end of the rods of the hammermill. The rod extension has a number of attachment points for attaching the rod extension to a reciprocating force generator. The reciprocating force generator then moves away from the hammermill, and pulls the rod extension with it, and also pulls the rod to which the rod extension is attached, in increments.

A handheld assembly tool system is provided for assembling fluid transfer lines that include a fitting and a tube. In an embodiment of the invention, the assembly tool system includes a fitting fixture for holding the fitting. The fitting fixture includes a flange for supporting the fitting and a selectively adjustable retaining block for securing the fitting against the flange. The assembly tool system also includes a tube fixture for holding the tube and a press device selectively operable to engage and move the fitting fixture such that a portion of the end fitting is forced into the tube.

A puller (10) for removing a compression sleeve from a pipe (38) generally comprised of a cylindrical body (24) containing on one end an internal cavity (28) to receive the pipe (38) and an external double thread (30) to engage a compression nut (34) and on the opposite end a threaded through screw (14) entering the cavity (28). A disk (22) attached at one end of the screw (14) bears on the end of the pipe (38) and a torque handle (12) at the other end is used to supply increasing pressure against the end of the pipe (38). The puller (10) is threadably attached to the compression nut (34) placing the pipe (38) into the internal cavity (28) against the disk (22) while the compression sleeve (36) is contained between the compression nut (34) and the puller (10). Turning the torque handle (12) urges the compression nut (34) and the compression sleeve (36) toward the end of the pipe (38) until the compression nut (34) and compression sleeve (36) are freed from the pipe (38).

In accordance with the teachings of the present invention, a method for producing a vehicle door is disclosed. Interior door components such as a window lift mechanism, a lock assembly, and a horizontal energy absorbing member are coupled to a door substructure. A finished exterior door panel having a class-A surface is adhesively bonded to the substructure, disposing the door interior components between the finished exterior door panel and a portion of the door substructure. The assembled door is coupled to a previously painted vehicle body.

A clamp for quickly, effectively and safely removing a cathode collar from an HDP deposition chamber for routine maintenance, cleaning or replacement of the collar. The clamp includes a pair of clamp plates which are capable of pivoting movement on respective ends of a connecting rod. A clamp shoe for gripping a corresponding edge of the annular collar is provided on the bottom end of each clamp plate, and a turnbuckle is fitted with a pair of threaded shafts which engage the upper end portions of the respective clamp plates. By rotating the turnbuckle, the threaded shafts are advanced away from each other against the clamp plates, which pivot on the connecting rod and cause the clamp shoes to tightly engage respective edges of the collar. The clamp is grasped to lift the collar from the chamber and replace the collar in the chamber after cleaning or maintenance.

A method is provided for remanufacturing a transmission assembly including an output shaft having an input end positioned adjacent an input sun gear. The method includes machining a pocket into the input end of the output shaft. A first roller needle bearing is positioned inside the pocket. The input sun gear is then replaced with a modified sun gear having a protruding center support hub configured to extend into the pocket and cooperate with the first roller needle bearing, thereby supporting the output shaft to prevent tilting of the output shaft to reduce wear.

An apparatus for removing a stator tube from a position about a rotor of a progressing cavity pump is provided. The apparatus includes an actuator assembly having a base and a piston which is longitudinally displaceable relative to the base, and a pusher rod. The base of the actuator assembly is removably attachable to a discharge end of the stator tube. The pusher rod is longitudinally releasably attachable to the piston at a plurality of locations along the length of the pusher rod and is located to engage the rotor when the base is coupled to the stator tube. The pusher rod is coupled to the piston and the piston is driven by the actuator assembly. With only slight modifications the apparatus may also be used to install the stator tube on the rotor when operated in a substantially opposite way.
