Brief Description: Torque Tube to Bellcrank Pushrod
23-3, Steps 1, 2, 3, & 4
Fabricate two W-1017A Torque Tube to Bellcrank Pushrods by cutting two pieces of AT6-049 X 1 1/4 to the length.
Cut-out guide and use it as a wrap-around template for locating the rivet holes in both ends of both W-1017A Torque Tube to Bellcrank Pushrods. Center-punch the "cross hairs" in the wrap-around template. Remove the template and use a #40 drill to make six pilot holes in each end of both torque tube to bellcrank push rods. Deburr the hole edges on the inside of the push rod tubes.
Insert a VA-169 Threaded Rod End into the end of one of the W-1017A Torque Tube to Bellcrank Push rods. Proper engagement of the threaded rod end in the torque tube to bellcrank push rod is when the end of the tube coincides with the edge of the taper in the threaded rod end. Using a #30 bit, match-drill the threaded rod end using the pilot holes in the torque tube to bellcrank push rod as drill guides. Insert clecos in the holes as match-drilling progresses around the circumference of the torque tube to bellcrank pushrod. Repeat until threaded rod ends have been match-drilled to both ends of both torque tube to bellcrank push rods. Remove the threaded rod ends from the torque tube to bellcrank pushrods and deburr all holes in all parts and prime all parts inside and out. Permanently install the threaded rod ends to the torque tube to bellcrank pushrods.
Install rod end bearings and jam nuts into the VA-169 Threaded Rod Ends. Theoretically the correct engagement of the rod end bearings yields a bearing center-to-bearing center length of 94 7/16 inches. The rod end bearing engagement may be adjusted during installation of the W-1017 Torque Tube to Bellcrank Pushrod.
