# Method and tooling for dismounting a cassette seal

## Abstract

A method and a tooling for dismounting a cassette seal having a radially inner ring mounted on a rotative shaft and a radially outer ring mounted in a receiving static bore is described. The method for dismounting the cassette seal includes a pressing step comprising displacing a first of the radially inner and outer rings with respect to its respective cylindrical support surface, along a first axial direction along the main axis; an extraction step, subsequent to the pressing step, comprising displacing the second of the radially inner and outer rings with respect to its respective cylindrical support surface, along a second axial direction opposite to the first axial direction along the main axis.
