| -4a- Nature of Complaint. | No. of Cars. | Last Qtr's. Total. | Remarks. ---|---|---|--- Servo Jaggers. | W. 3. N. 12. P. - 15. | 14. | On early Phantoms a rubber block is fitted to provide a damping device on the servo shaft. On later cars and present production a flat spring plate is standardised. Also, a friction device to the swinging arm can now be fitted to the older cars. A new fabric has been standardised. Steering Joggles and Wobbles. | W. - N. 11. P. 2. 13. | 6. | The various designs of worm and nut, and new type side and cross steering tubes, enable us to deal with all complaints satisfactorily. Latest production chassis appear to be almost free from complaints. Tappets Noisy. | W. 5. N. 28. P. 8. 41. | 33. | The grooved bushes for improved lubrication scheme are satisfactory and cure complaints, and are standard on present production. Throttles Sticking. | W. - N. 24. P. 4. 28. | 26. | The new design roller bearing throttle overcomes the trouble on the old cars. On the later cars with aluminium throttle bodies the butterfly valve sticks due to carbon forming on the edges. Something should be done about this. Water Pump Failures. | W. 2. N. 18. P. - 20. | 25. | The packing gland next to the water pump is not now a tight fit on the water pump spindle. | ||
