| To CWB. from Hs.{Lord Ernest Hives - Chair} X9770 Hs{Lord Ernest Hives - Chair}5/LG16.12.24. 48-PK CAR. X9300 We have found that the slipper wheel on this car was practically seized up on the friction surfaces. Since we have made this correct the engine vibrations which had come up on this car, have disappeared. The car now is normal. There is, however, still left what is at present known as a 'transmission groan' at 30 m.p.h. The way in which 48-PK car got worse was unusual, therefore, it is interesting to have found a definite cause for this. Hs.{Lord Ernest Hives - Chair} | ||
