An apparatus (60) for applying a dry film lubricant comprises a tool (62) and a pad (64). The tool (62) includes a handle (66), a cranked member (68) and a supporting member (70). The pad (64) is removably locatable on the supporting member (64). The supporting member (70) is oval in cross-section and the pad (64) includes an oval cross-section hollow member removably locatable on the supporting member (70). The supporting member (70) comprises locking means (78) to lock the pad (64) on the supporting member (70). The supporting member (70) comprises positioning means (80) to position the pad (64) on the supporting member (70). The tool (62) also has a shielding member (72) spaced from and arranged parallel to the supporting member (70). The handle (66) is arranged in a plane (A) substantially parallel to a plane (B) containing the supporting member (70) and to a plane (C) containing the shielding member (72). The pad (64) is substantially dovetail shape in cross-section to correspond to a rotor slot (40).
An apparatus for applying a dry film lubricant to a rotor slot comprising a tool and a pad, the tool including a handle and a supporting member, the pad is removably locatable on the supporting member, characterised in that the pad includes a hollow member removably locatable on the supporting member, the supporting member and the hollow member having matching cross-sectional shapes to prevent relative rotation, and the pad has the same cross-sectional shape as the rotor slot.
A method of applying a dry film lubricant to a rotor slot comprising removing the rotor blade from the rotor slot, applying the dry film lubricant to the rotor slot using a tool and a pad, the tool including a handle and a supporting member, the pad is removably locatable on the supporting member, the pad includes a hollow member removably locatable on the supporting member, the supporting member and the hollow member have matching cross-sectional shapes to prevent relative rotation, and the pad has the same cross-sectional shape as the rotor slot.
