Abstract: A unique, new and useful structure and method is provided for effectively and efficiently engaging and manipulating a crossover tube of a gas turbine. The tool is manipulated to a gripping position in which it securely engages the spring loaded locks of a crossover tube while applying a reaction force to a portion of the burner basket that is associated with the crossover tube, so that manipulating the handle manipulates the crossover tube that is engaged by the tool. A preferred version of the tool has specially designed structure for coupling a handle with the gripper and follower structure such that the tool can effectively and efficiently reach and manipulate crossover tubes that are in particularly difficult to reach areas of a gas turbine.
