1. A tool for removing a seal from an engine component, wherein an interference fit is provided between an inner diameter (ID) surface of the seal and an outer diameter (OD) surface of the engine component, the ID surface and the OD surface extending circumferentially around a central axis, the tool comprising:
a support defining an annular seat offering an axial abutment for the seal around the OD surface of the engine component, the axial abutment restraining axial movement of the seal in a first axial direction, the support including:
a base defining an enclosure for receiving the engine component,
shell halves engageable around the seal on the OD surface of the engine component, the shell halves seated on the base, the shell halves jointly forming the annular seal, and
a cap releasably securable to the base over the shell halves, the cap having a central projection defining a central hole in registry with a counterbore formed by the shell halves, the central projection engageable in the counterbore; and

a pusher axially engageable with the engine component to transfer a pushing force to the engine component in the first axial direction.
