Y4261 We found on 5-Goshawk-11 car that the front springs were loose on the axle and that the slots in the sheath had worn and the corners had been rubbed off the nut on the centre bolt of the spring, which is let into the axle, owing to the fidgeting of the spring on the axle. On this car there was no question of the sheaths butting against the axle before the springs were gripped, so that the only question is whether the clips were pulled up sufficiently tight originally. The appearance of the clips does not lead one to believe that they have been tight above the top of the thread. We are sending the clips and sheath to "E". Our experience with the 40/50 is that we find it impossible to keep the clips on the front springs tight. A special point is made of these during the erection and they always have to be tightened up again on Test and the Repair Dept. state that every car they handle in the Repair Dept. they find these clips loose. Our experience on the Bump Test with Goshawk-11 shows that we still get the spring clips working loose and once the spring clips are loose, the sheath does not appear to do much good as shown by the wear which has taken place. If the sheath does not stand up, then the nut on the end of the centre bolt is liable to get severely punished and fail in the same manner as 4-Goshawk-11. contd:- | ||
