The present invention relates to a vane installation tool 40. The tool 40 is formed by two inflatable, substantially semi-circular tubes 42 which are placed between a rotor assembly 40 and a vane assembly during the installation of the vane assembly. The tubes 42 are each positioned adjacent an inner end 50 of the vanes 14 in the vane assembly and are each inflated to apply a lifting force to the vanes 14. The vanes are then attached to the engine case 12.
