Abstract
A turbine engine blade removal apparatus with a pair of opposed outwardly biased blocks are positioned proximal a blade root and corresponding rotor disc slot between opposed axial faces of the subject first rotor disc and an adjoining second rotor disc. The blocks are outwardly biased in abutting contact with first and second rotor disc axial faces, aligning an aperture of a guide bushing with an exposed axial face of the blade root, the guide bushing coupled to at least the first block. A punch is inserted in the guide bushing aperture so that a punch tip is in abutting relationship with the blade root axial face. An impact tool drives an opposite impact end of the punch, causing the punch to direct a relative driving force on the blade root, separating the blade root from the corresponding rotor disc slot.
