An apparatus and method for servicing a combustion liner in a combustion case of a turbine is provided. The apparatus includes an elongated bar having a handle at one end and a force applying member at an opposing end of the elongated bar. An attachment member is configured for attachment to a flange of the combustion case. The attachment member is also configured for pivotal attachment to the elongated bar. The apparatus is configured to apply a radially outward force on a downstream portion of the combustion liner when a radially inward force is applied to the handle.

A method and a machining kit for machining a bore hole into a shroud block are disclosed. The method includes designating a location of the bore hole on an exterior surface of the shroud block, positioning the shroud block in a machining device, securing the shroud block in the machining device, and machining the bore hole in the shroud block. The machining device includes a locating tool, a machining tool, a platform, a securing device, and a radial support. The radial support is configured to mate with a radial exterior surface of the shroud block such that a machining axis of the machining device may be aligned with a radial axis of the shroud block during positioning.

A system for removing a stator vane includes a platform, a cutting tool connected to the platform, and a sliding connection between the cutting tool and the platform. The system further includes means for advancing the cutting tool with respect to the platform. A method for removing a stator vane includes positioning a platform inside a casing that surrounds at least a portion of the stator vane. The method further includes pivoting a cutting tool with respect to the platform, sliding the cutting tool in a plane with respect to the stator vane, and cutting the stator vane with the cutting tool.

This disclosure describes embodiments of an apparatus for use to extract a rotor from a generator. The apparatus can include a central mount element that secures to the end of the rotor. A pair of support members coupled to the sides of the central mount element. The support members can include a load bearing element that permits travel of the apparatus on a surface, e.g., a platform proximate to the turbine generator. During implementation, the apparatus is configured to direct pulling forces along the center axis of the rotor to restrict movement of the rotor and, in particular, limit rotation of the rotor that can result in inadvertent contact with the stator or other parts of the generator.

A method and system adapted for removing one or more shells from an assembly of multiple annular shells, for example, turbine shells of a gas turbine engine. The method includes removing an upper shell positioned in an upper position relative to a lower shell of the assembly of multiple annular shells, and then positioning and securing a counterweight in the upper position and securing the counterweight to the lower shell as a replacement for the upper shell in the upper position. The counterweight and the lower shell are then rotated in unison until the lower shell is in the upper position and the counterweight is in a lower position previously occupied by the lower shell. Thereafter, the lower shell can be removed from the assembly.

A system for rotating a turbine shell includes a first platform and a first trunnion rotatably connected to the first platform. A second platform is separated from the first platform, and a second trunnion is separated from the first trunnion and rotatably connected to the second platform. The system further includes structure for rotating the first trunnion.

A method of assembling a gearbox handling assembly to facilitate removal of a gearbox from a wind turbine uptower from the wind turbine. The wind turbine includes a rotor rotatably coupled to the gearbox with a rotor shaft. The gearbox and the rotor shaft are supported from a support frame. The method includes coupling a support assembly between the gearbox and the support frame for supporting the gearbox from the support frame. A positioning assembly is coupled to the support frame. The positioning assembly is configured to contact the gearbox to move the gearbox between a first position wherein the gearbox is operatively coupled to the rotor shaft and a second position wherein the gearbox is operatively decoupled and spaced from the rotor shaft to facilitate removing the gearbox from the wind turbine without removing the rotor from the wind turbine.
