1. A stator vane removal system comprising:
a reaction platform configured to couple between opposing sides of a slot defined in an inner surface of a casing of a rotary machine, wherein at least one stator vane is retained in the slot, said reaction platform comprises a block and at least one sleeve configured to slidably couple to said block along at least one wedge surface; and
an actuator configured to couple to said reaction platform, said at least one wedge surface is configured to induce a coupling force exerted by said reaction platform to the opposing sides of the slot in response to a pushing force applied by said actuator to the at least one stator vane in the slot.
