A tool for mounting a chisel on a chisel holder, having an actuating member, which has a push-off section, wherein the actuating member can be displaced along a displacement direction. It is possible to simplify changing the chisel if the actuating member can be shifted by an actuating unit. The actuating unit has a draw-in section, which is spaced apart from the push-off section and is arranged transversely with respect to the displacement direction of the actuating member. The actuating member can be power-operated bidirectionally in the displacement direction by the actuating unit.

A puller for pulling an element, such as a pulley or seal, from an assembly to which it is fitted. The puller generally includes a central body having a longitudinal axis, an adjustment ring threaded on the body for moving longitudinally with rotation, slide followers coupled to the ring and moving longitudinally with ring rotation, a plurality of leg assemblies, each including a foot and two legs pivotly attaching the foot to the body so as to form a parallelogram, and a arm pivotly connecting each slide follower to a leg assembly for expanding or contracting the leg assembly. Each foot has one or more foot flanges, each with an engagement surface for engaging with the element to be pulled; the orientation of the engagement surfaces being predetermined so as to not disengage from the element and to provide uniform pull and minimum pressure.

A puller structure includes a threaded rod, a connecting member, a fixing base, and a driven base. The connecting member is topped with a wing nut. The threaded rod extends downward through the wing nut, the fixing base, and the driven base. The connecting member has a lower portion fixedly connected to the driven base. The fixing base includes a plurality of first fixing arms that extend permanently and obliquely upward. The driven base includes a plurality of second fixing arms that extend outward. The first fixing arms correspond in position respectively to and are shorter than the second fixing arms. Each first or second fixing arm is provided with a groove that extends in the same direction as the fixing arm. A gripping arm is slidably provided in the grooves of each corresponding pair of fixing arms through two pairs of protruding blocks respectively.

A method for preloading a bearing includes releasably, threadably, and directly attaching an attaching member to a circumferential outside surface of an exposed end of a threaded shaft of an axle or spindle. A frame is axially separated from, and coupled to, the attaching member. A plurality of extensions extends from the frame axially past the attaching member toward the wheel hub assembly. An adjustment mechanism moves the frame and the plurality of extensions axially towards the wheel hub assembly to contact the wheel hub assembly and/or the bearing to apply a preload to the bearing within the wheel hub assembly.

A tool for inserting and removing components, in particular bearings, bushes or the like, particularly in the automotive sector, has a spindle, a first sleeve body having a first ramp-form outer circumferential surface and a through-hole, through which the spindle can be axially guided, a second sleeve body having a second ramp-form outer circumferential surface and a through-hole, through which the spindle can be axially guided, and also a first pressure body and a second pressure body.

The invention herein comprises a kit and method that may be used to replace damaged and worn stabilizer bearings in both the Echo and Delta Apache helicopter. The kit includes a removal assembly that includes a bolt coupled to a cutting means. Tightening of the bolt causes the cutting means to cut the damaged and worn bearing from its housing. A staking means is disclosed that allows the staking of a replacement bearing in the housing is provided. The staking assembly joins the replacement bearing to the housing so that it is tight. And, an installation assembly is disclosed that utilizes the bolt utilized in the cutting means coupled to a hex nut.

A sleeve installer is provided, including: a threaded rod; an abutting unit, disposed around and movable along the threaded rod, including first and second abutting assemblies, one of the first and second abutting assemblies being configured to be abutted against a barrel portion of a sleeve assembly, the other of the first and second abutting assemblies being configured to be abutted against a tubular member of the sleeve assembly; and a push unit, including first and second push members which are connected to two opposite ends of the threaded rod, at least one of the first and second push members being movably screwed to the threaded rod, the first push member including a head portion and an urging assembly located at a side of the head portion, the urging assembly and the second push member being respectively abutted against two opposite sides of the abutting unit.

The present invention relates to a tool for expediting the separation of different components of a wheel hub. The tool includes a base and a top that is rotatably connected to the base. The tool may also include a bearing that is connected to the base and to the top, where the bearing enables the rotation of the top relative to the base. A portion of a wheel hub may be located relative to the top, after which the wheel hub and top can be rotated. While this occurs, a heat source can be applied to a portion of the wheel hub to enable even heating. As a result of this heating and related expansion, a first wheel hub piece may be separated from a second wheel hub piece.
