Methods of cleaning flow path components of power systems, and sump purge kits used in the same or related methods are disclosed. A method of cleaning may include removing a casing of the turbine system to expose a rotor of the turbine system, a plurality of flow path components coupled to the rotor and/or the casing, and a sump system in communication with the rotor. The method may also include pressurizing the sump system in communication with the rotor, and sealing a plurality of openings formed in the rotor. Additionally, the method may include exposing the rotor and the plurality of flow path components to steam to dry hydrocarbons formed on a surface of the rotor and a surface of the plurality of flow path components, and blasting the rotor and the plurality of flow path components with solid carbon dioxide (CO) to dislodge the dried hydrocarbons.

A positioning tool for axially positioning a circular lubricant dam insert on a splined drive shaft may include a circular body having an inner surface configured to slide over an outer surface of the splined drive shaft. A first plurality of splines may be positioned on an inner surface of the circular body, the first plurality of splines mating with a second plurality of splines on the outer surface of the splined drive shaft. A depth setting member may be positioned on the circular body that defines an axial extent to which the circular body slides over the outer surface of the splined drive shaft. A position setting element may extend axially from the circular body to contact an axial end of the insert to axially position the insert on the splined drive shaft.

A method to monitor the health status of a rolling bearing of a machinery, including a first acquiring step of a rotation speed value of a shaft coupled to the rolling bearing, a second acquiring step of a first signal generated by a vibration sensor located on the machinery in a position distant from the rolling bearing, and a first calculating step of a variation of the shaft rotation speed value during a predetermined time interval, and if the calculated variation of the rotation speed falls within a predetermined variation interval, performing a first filtering step of the first signal with a first algorithm based on a vibration produced by parts of the machinery different from the bearing at the rotation speed value, so as to obtain a second signal representative of a bearing health status.
