Abstract
A method is provided for pulling a bearing body off the rotor of a gas turbine having a casing, while the casing is closed. The method includes fixing a shaft extension on the relevant end of the rotor. In order to free the bearing body of the weight of the rotor, the method involves supporting the rotor and/or holding the rotor. The method further includes fitting sliding elements between the bearing body and the rotor, and moving the bearing body axially along the machine axis onto the shaft extension.
