A torque transmission member for transmitting torque between a first rotating member and a second rotating member is provided. The torque transmission member has a first connection part and a second connection part which are concentrically arranged and fixedly connected with each other, wherein the first connection part is fixedly connected to the first rotating member, the second connection part is connected to the second rotating member in a torsion-proof manner, and the second connection part has a central hole for receiving the second rotating member. A cylindrical centering reference member is provided, the torque transmission member and the centering reference member are coaxially arranged by a centering tool during the process of assembling the torque transmission member, wherein the first connection part is provided with at least two through holes, and the centering tool passes through the through holes during a process of centering. A centering tool is provided for coaxially arranging the above-mentioned torque transmission member and a fixed cylindrical centering reference member, wherein the centering tool has at least two centering arms, wherein the centering arms are capable of passing through the through holes.

An apparatus is provided for removing a component from a device, where the component includes a cylindrical portion and a shoulder adjacent the cylindrical portion. The apparatus includes a base, a puller and a shaft. The base includes a first mount, a second mount and a bridge extending between and connected to the first mount and the second mount. The first mount and the second mount are each configured to engage with the device. The puller includes a forked flange configured to abut against the shoulder of the component when the cylindrical portion of the component is within a channel of the forked flange. The shaft includes a threaded portion mated with a threaded aperture in the bridge. A distal end portion of the shaft is rotatably connected to the puller.

A method and tool system coaxially orients inner clutch plates with outer clutch plates on a tool. The tool includes a plurality of guide members circumferentially spaced apart, each guide member matingly engages a toothed portion of each inner clutch plate to position the inner clutch plates coaxially. A pre-build fixture includes a plurality of alignment pillars, at least one support block, and an alignment member. The alignment pillars are circumferentially spaced apart about a fixture axis. Each alignment pillar has a curved inner face that faces radially inward and has an arclength that is configured to coincide with and fit within a corresponding gap between radially outward facing teeth of each outer clutch plate. The support block supports the tool coaxially with the fixture. The alignment member engages the tool to inhibit rotation of the tool when the tool is supported coaxially with the fixture by the support block.

A clutch brake removal tool configured to facilitate the removal of a single piece clutch brake from an input shaft. The clutch brake removal tool includes a rectangular shaped body having a plurality of walls forming a hollow interior volume. The body includes a first sidewall and a second sidewall and further includes a first end and a second end. The body has an opening at the second end providing access to the interior volume. The second end of the body has a leading edge wherein the leading edge is formed in a semicircular shaft so as to mateably abut against an input shaft. The first sidewall includes a first slot formed therein wherein the second end of the first slot is contiguous with the opening of the body. The second sidewall includes a second slot formed identical to the first slot and located on the opposing sidewall.

An apparatus is provided for removing a component from a device, where the component includes a cylindrical portion and a shoulder adjacent the cylindrical portion. The apparatus includes a base, a puller and a shaft. The base includes a first mount, a second mount and a bridge extending between and connected to the first mount and the second mount.
