Abstract

A gas turbine engine flanged shaft (120) is provided with a plurality of anti-score plates (6a, 6b) each of which has two openings which are aligned with corresponding apertures on the flange. Bolts (4) pass through the openings and apertures to attach the anti-score plates (6a, 6b) to the flange (2). The anti-score plates (6a, 6b) have different masses to facilitate shaft balancing.
