Brief Description: Control Torque Tube
|
|
Today, I fitted the torque tube in my right wing, just in front of the main spar. I built the torque tube bracket per the manual without problems. I cut the head off a 1/4 bolt per the manual, and then chucked it in the drill press and with a bastard file, made a point on the head end. This is used to get a good fit for the end bracket hole. The only problem was in installing the torque tube assembly to the bracket, the manual calls for an AN4-13A bolt, an AN960-418 washer, then an AIL-26 bushing (inner) in the AIL-27 brass bushing that is fitted to the bracket. Then an AN970-4 Penny Washer and another AN960-418 washer between the bushings and the torque tube. What I found was that the AIL-26 bushing is 5/32” longer than the AIL-27 bushing it fits in. That introduces right to left movement in the torque tube. I put a question to the rebel forum whether or not I should trim the AIL-26 busing to fit? In addition, prior to final assembly, should I lubricate the bushing with some grease or something?
I also worked on the center hangar bracket and delrin bearing, but miscut the ears on the bracket and didn't have sufficient clearance for the 5000-3 nut plates. Soooooo -- I'll try again tomorrow.
