| LF/HWS.9/GB.14.11.38. No.2. had become free and permitted some movement of the pinions on their splines. It appears that this failure was due to race "creep" in the new design and had produced appreciable fretting of the splines. It is conceivable that this defect could produce excessive vibration in the wheelcase when running at the critical speed. ----------------- Lr{Mr Ellor}/H.W.S. | ||
