A set of tools for removing a half turn of a coil from a slot of a dynamoelectric machine. The set of tools includes a coil cutting tool for cutting the coil, an upending tool that grips the coil at an end of the coil where the coil was cut and hydraulically or pneumatically lifts the end of the coil at least partially out of the slot, and an extraction tool that hydraulically or pneumatically grips the upended portion of the coil and pulls the coil from the slot hydraulically or pneumatically a segment at a time.

Set of tools for removing a coil from a core slot of a dynamoelectric machine

A method and apparatus for compressing the endplate of an electric generator to relieve the restraining force on a plurality of key blocks that restrain the endplate in compression. The method includes simultaneously applying independent compressive loads at each of the key block locations to the endplate to relieve pressures on the key blocks and removing the key blocks so the endplate can be removed.

Method for removing the endplate of an electric generator

A method and apparatus which quickly clamps onto the copper strand bundle in the slot of a dynamoelectric machine and rips out the coil from the slot one axial position at a time. As the copper bundle is ripped from the slot the tooling moves along the slot from one end to the other.
