Thank you Mark,
My book known as Advisory Circular 43.13-1B with Change 1 read 160 to 190 inch pounds with a maximum torque of 390 inch pounds. Jon’s recommendation of 20 foot pounds AKA 240 inch pounds is well within that range. This sort of divergence is exactly my reason for asking.
I have found that when working with unusual structures that the standard torque range, 160-190 inch pounds, is not what is used. The castellated nut being lined up with the hole precludes a specific torque although different thickness AN washers make it possible to get close.
Thank you Jon,
I called the Sport Copter office and they don’t open until 8:00.
I will call back later and order the sheets and tracking tabs, my tabs are a little tired.
I found the marks on the aluminum plates confusing. I have an A and a B blade and an A and B end of the hub bar. Do the aluminum plates marked A and B stay with the A and B sides of the hub bar or is A on the top and B on the bottom? I may have assembled them incorectly previously so going by the fading on the plates my not be best practice.
Thank you, Vance
