Abstract: A spring loaded mud flap tool (10) includes a hook element (20) carried by one a first of a drive rod (30). The hook end of the hook element is sized to grasp the end of the spring carried within the hanger tube of the mud flap assembly. A handle assembly (80) is carried by a second end of the drive rod. The handle assembly allows the user to manipulate the hook until it successfully grasps the spring. A bearing assembly (40) is carried on the threaded surface of the drive rod (30), and supports a pair of diametrically opposed crank handles (70). In operation, the bearing assembly rests on the open end of the hanger tube. Revolution of the crank handles turns the drive rod, which retracts the hook element and therefore retracts the spring. The force of the spring pulling the tool (10) into the hanger tube is offset by an equal force exerted by the bearing assembly on the rim of the hanger tube. A safety chain (90) connects the hanger tube and the bearing assembly.

Abstract: A tool 50 for removing a hub assembly (6) from a chamber (14) in a gear housing (4) of an outboard engine (2) has a cylindrical body (52) with a first end (54) and a second end (56). Proximate the first end is a flange (98) for seated engagement over an opening (18) to the chamber to limit the depth the tool enters the chamber. At the second end is a bore (66) with protruding teeth (70) for engaging longitudinal grooves (26) of a shaft (8) of the hub assembly to prevent the shaft from rotating. A nut (78) with depending disc (82), a pair of washers (92) and a flat roller bearing (94) are disposed into a recess (72) that is concentrically aligned and congruent with the bore. The nut engages a threaded end (22) of the shaft and pulls the hub assembly axially within the chamber toward the tool until a bearing carrier (10) of the assembly engages the tool.

A ball cage is held in position surrounding the inner race, and balls are inserted on the rim, in the cage, and against the inner race so that they are adequately engaged in the inner race for assembly. When all of the balls are positioned in tracks of the inner race, and within the cage, an outer race is brought into position over the rim. The rim is tapered such that a sufficient periphery of the balls is exposed above the rim for engagement with tracks of the outer race. The assemblage is then inverted, allowing the inner race to drop into the outer race, carrying the balls along the tracks and the cage with the balls.

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.

Abstract: An extractor for use in removing a solid, smooth, press fit shaft from a sing where access to the shaft is restricted. The extractor has a jacket and a collet. The collet fits around the shaft and the collet in turn fits within the jacket. The exterior of the collet end within which the shaft is placed is tapered and this tapered portion of the collet fits within a similarly tapered bore in the jacket. The collet has a threaded end opposite the tapered portion and the threaded end protrudes from the jacket when the tapered portion is fully seated within the tapered bore of the jacket. A nut is placed onto the threaded end and tightened such that the collet is pulled further into the jacket. The movement of the tapered portion within the tapered bore creates a wedging action which forces the collet against the shaft. As the nut is further tightened, the collet grips the shaft tighter.

Abstract: A bushing installed in a bore with an interference fit is extracted concentrically from the bore 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 extracted from the other end of the bore. The force to press the bushing out of 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 in contact with a cup having a cylindrical sidewall surrounding the bushing to be extracted and in contact with the side of the part opposite from which the bushing is being extracted from the bore.

Abstract: Apparatus and method for removing a bearing. More particularly, the apparatus and method are designed to simplify the removal and replacement of all bearing cups and cones in an automotive automatic transmission. The apparatus includes an elongate bearing drive shaft; an adjustably sized mandrel which includes one or more bearing drive shoulders; a mandrel spreader for adjusting the mandrel drive shoulder to a predetermined dimension; and a collar or clamp ring for limiting the mandrel to a maximum outer dimension surrounding an outer surface of the bearing, without substantial slippage, during the removal and insertion steps, in one embodiment.
