Adjustable assembly for use in the repair or replacement of a pitch change link or rod end of critical predetermined length

摘要

For use while repairing or replacing an elongate variable length device of critical overall length, such as a pitch change link device for a helicopter blade, which device includes a joint threadably connected for axial movement on each end to effect adjustment of the overall length of the device by threaded movement of one or both of the adjustable joints; an assembly which includes an elongate base on which a fixed and a movable mounting post are connected in upstanding spaced apart parallel relation to one another with the movable post being movable along the length of the base in a track structure so as to be capable of varying the spacing between the posts; the posts are constructed to removably receive and support the joints on the device, and the movable post is adapted to be locked in a fixed spaced relationship from the fixed post to record and preserve the exact length of the critical length device while it is being repaired.
