Apparatus for removing blades affixed in a generally axially oriented groove by a pin from a rotor of an axial flow machine having multiple rows of blades, said apparatus comprising: a base portion which fits between adjacent rows of blades; a plunger slidably disposed in said base portion so as to be axially aligned with said groove; means for applying a force to said plunger sufficient to shear one of said pins and move one of said blades in one of said grooves; said means for applying a force comprising a hydraulic cylinder, a rocker arm pivotally mounted in the base portion, one end thereof contacting the plunger and the other end receiving the force from the hydraulic cylinder, and a spring interposed between the hydraulic cylinder and the rocker arm; and means for clamping said base adjacent one of said blades and for resisting the reactive forces on said base when force is applied to said plunger.
