The invention relates to a device for installing and removing a component on a gas turbine, having a rail system on which in particular a rotor can be displaced along a predetermined displacement axis, and having a terminal positioning part which is fixedly connected to the rail system. The positioning part has at least one guide portion which is designed to co-operate mechanically with a respective counterpart guide portion on the housing of the gas turbine, in order to achieve a suitable orientation of the device with respect to the housing of the gas turbine. The positioning part also has at least one connecting section which is designed in each case to form a fixed but releasable connection to a respective counterpart connecting section on the housing of the gas turbine construct.

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 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 snap ring insertion apparatus is provided and configured to install a snap ring on a structural member. The snap ring insertion apparatus includes a pneumatic cylinder assembly configured to receive compressed gas and transfer a power of an expansion of the compressed gas to linear movement of a rod. An insertion assembly is coupled to the rod. The insertion assembly has an expander pin and a plurality of fingers pivotably coupled to a finger support member. The finger support member is coupled to the rod in a manner such that linear movement of the rod provides linear movement of the expander pin and pivoting movement of the fingers. Pivoting movement of the fingers results in engagement of the fingers with a snap ring and further pivoting of the fingers results in an expansion of the snap ring in a radial direction.

A lock nut system includes a nut threadably engageable with a shaft and a keeper having a projection configured to fit within a slot of the shaft to engage the shaft. A retaining member is formed separate from the keeper and the nut. The retaining member is receivable within a slot of the nut to engage the nut. A portion of the retaining member engages the keeper by extending into a keeper cavity within the keeper. The nut is lockable onto the shaft when the projection of the keeper is fit within the slot and the keeper is abutted and supported by an inner shoulder of the nut and the retaining member engages the nut and the portion of the retaining member extends into the cavity within the keeper.
