  • Patent number: 5593275
    Abstract: A compressor stator vane assemblage includes a first metal bushing disposed within a bore through the compressor casing and bolted to the casing by externally accessible bolts. A second composite bushing is disposed within the first bushing and receives the spindle of the stator vane. Reduced diameter portions of the spindle project through openings in the first and second bushings. A lever attaches to the spindle portion and is movable to rotate the vane. By removing the bolts, the first and second bushings can be removed from the casing for replacement or rotation of 180.degree. for prolonged service life without disassembly of the casing or removal of the stator vane.
