Abstract: An installation tool for use with a liner sleeve attachment, such as a nutplate assembly for mounting onto a substrate blind side as disclosed in U.S. Pat. No. 5,704,747. The installation tool includes retractable grip jaws for gripping and pulling a fixture pin protruding from the attachment, for initially advancing a tapered tool nose piece into deforming engagement with an attachment liner sleeve leading end to flare and/or expand the liner sleeve to lock the liner sleeve onto the substrate. Continued pulling action exerts a sufficient force to collapse a fixture pin head and thereby permit pull-removal of the fixture pin from the attachment. The nose piece is carried by a retractable inner housing normally retained in an advanced position for deforming the liner sleeve, and thereafter movable to a retracted position spaced from the liner sleeve to accommodate substantially unobstructed fixture pin separation from the attachment.

Abstract: This is a device use for removing a hinge pin from its hinge assembly safely, quickly, and easily, using lever action instead of the traditional hammering or banging. This device is placed over the top of the door hinge, where it rests by grabbing the head of the hinge pin. It has a handle that is attached to a gear wheel, which rotates on a shaft, when the handle is moved up and down. It has an L shaped arm that has a thin rod attached to it lower part. The L shaped arm has teeth on it backside, which interlocks with the gear wheel. When the handle is pulled sown, the gear wheel rotates and raised the L shaped arm. This raises the thin rod that is attached to the L shaped arm, which in turn pushes up against the bottom of the hinge pin, thus raising the hinge pin up and out of the door hinge assembly.

Abstract: A glo-plug extractor is disclosed. An internally threaded sleeve is threaded over an externally threaded bolt having a bolt head at one end and a set of jaws at the other. The jaws are fitted to lock onto the head of a fully unscrewed, yet bound glo-plug. After the jaws are locked onto the glo-plug, the sleeve is braced against the engine head either by screwing the sleeve down over the jaws until it contacts the engine head or by placing some bracing apparatus such as a spacer or a set of legs between the sleeve and the engine head. Once the sleeve is braced, it must be locked in place using a locking apparatus such as vice grips or a wrench. The bolt head is then used to rotate the bolt relative to the sleeve. This rotation causes the sleeve to exert a pulling force on the bound glo-plug which either extracts the glo-plug whole or breaks it.

The retainer-key kit is then withdrawn from the positioning device by retracting the linear actuator. The gripper and retainer-key kit are then transported to the cylinder head so that the retainer-key kit is substantially positioned for application to the valve stem.

Abstract: Apparatus includes a pilot stud and a ram. The pilot stud is aligned with an end of a shaft. A rotating member is adapted to receive axially inner and outer rolling bearings and be supported by the rolling bearings for rotation with respect to the shaft. The rotating member has a spacer for maintaining a desired separation between the rolling bearings. The rolling bearings and the rotating member are mounted on the pilot stud. The ram has an abutment member that is adapted to engage the outer rolling bearing. The ram is aligned with and moved toward the shaft. Movement of the ram toward the shaft causes the abutment member to move the outer rolling bearing against the spacer and onto the shaft. Also, this movement of the ram toward the shaft causes the spacer to move the inner rolling bearing onto the shaft. So, a single stroke of the ram mounts the rolling bearings and the rotating member onto the shaft.

Abstract: A clutch removal tool formed of an elongated member having a center portion with opposing semi-circular portions. A hole is formed in this center portion for engaging over the pushrod adjusting screw of a motorcycle clutch assembly. The clutch removal tool also includes opposing end portions tapering inwardly away from the center portion. The length of clutch removal tool enables the end portions to make contact against the clutch assembly spring collar without interference with the spring tension adjusting nuts. In use, the clutch removal tool is installed over the pushrod adjusting screw. The end portions engage against the spring collar. The pushrod adjusting screw locknut is tightened against the clutch removal tool. This releases the pressure against the spring tension adjusting nuts. The spring tension adjusting nuts can be easily removed without interference from the clutch removal tool. Once the spring tension adjusting nuts are removed, the pressure plate assembly is removed.

Abstract: Two bushings are aligned coaxially with a bore in a part in preparation for installation concentrically in the two ends of the bore with an interference fit, using an elongated mandrel which is maintained coaxially on the bore centerline by a guide inserted in one end of the bore while the bushing is pressed into the other end of the bore. The force to press the bushings into the bore is exerted by a pulling tool to which the mandrel is coupled, and that force is transmitted through the mandrel to the bushing by way of a collar attached to the mandrel. The force of the pulling tool exerted on the mandrel is reacted through an anvil attached to the barrel of the pulling tool and effectively in contact with the side of the part opposite to which the bushing is being pressed into the bore. The faces of the collar and the anvil are machined flat and perpendicular to the axis of the mandrel so that the squeezing force exerted between them on the bushing and the part is parallel to the axis of the bore.

Abstract: A support hinge is installed between the elevation and azimuth housings of the antenna pedestal. A jack is installed between these same housings at a location opposite to that at which the hinge is located.

A bearing adapter having a plurality of arms extending therefrom is suspended from the winch and lowered until it is in contact with the bearing. Bolts are then used to join each of the arms to a threaded portion of the bearing. The bearing is then lifted out of the azimuth housing, swung pivotally away from such housing and lowered from the antenna pedestal. A new bearing is installed by reversing the above indicated procedure.
