Abstract: Disclosed is an apparatus that precisely measures the bearings in a rotor pitch link. The apparatus permits measurements to within a thousandths of an inch to be taken in multiple perpendicular orientations. Namely, measurements can be taken in the axial direction, in the longitudinal radial direction, and in the transverse radial direction. All of these measurements can be taken without having to reorient the pitch link. By using the apparatus of the present invention, a user can detect unacceptable levels of wear within the pitch link bearings to thereby permit timely replacement and/or repair.
