(Bag 9-III)Attention! Do not screw the tail pitch connecting rod 0916e hard against the bearing 0916b of the tail pitch slider bearingsleeve 0916a. The tail pitch slider bush 0916c has a small spanner flat at the bund to hold it tight. Always check whether thebearings 0916b runns smooth whilst doing this job. If you feel a rough running bearing unscrew the part 0916e a little again.The bearings do not have a spacer between them, therefore screwing too hard would lead to tension in the inner rings andmake them bind or even damage them. Screw the tail pitch connecting rod so that the tail pitch slider bearing sleeve 0916ahas not any axial play.The advantage of this construction is that by exact screwing one can compensate for possible bearing play, even afterseveral operations.When the tail pitch slider bush 0916c cannot be moved freely on the tail output shaft 0910, in most cases the reason is acontraction of the front part of the bush after the tail pitch connecting rod has been screwed on. You can solve the problem bysoftening the inner edge with a small round file.Tighten the threaded link ball 0916d carefully because it only has a M2 thread. Secure it using Loctite.26
