| -3- Nature of Complaint. No. of Cars. Last Qtr's. Total. Remarks. Engine Slipper Drive Seized. W. 1. N. 17. P. 2. 20. 30. In spite of carrying out all the latest improvements, i.e. cotton duck friction washers and new spring poundage, we are still getting slipper drives which increase in loading and become uneven in action with running. A new design of slipper wheel is now on production, which could be adapted to Phantom I if it is thought advisable. Exhaust Blows. W. 4. N. 25. P. 7. 36. 28. The difference in expansion between the aluminium cylinder head and the exhaust pipes is so great that the washers do not cover the joints and are burnt away. We are now fitting a modified washer with steel centre which up to now is satisfactory. Exhaust Manifold Broken. W. 5. N. 11. P. 1. 17. 18. Breakages take place between the studs and the dowel, also the rear down pipe flange. This is an expansion trouble. See Depot Sheet No. Hm.{Capt. W. Hallam - Head Repairs}145. Hydraulic shock Absorbers Knocking. W. 10. N. 13. P. 2. 25. 20. Depot Sheet No. Hm.{Capt. W. Hallam - Head Repairs}105 has been issued showing the drilled valves in connection with the 20 HP. Chassis. This is also applicable to the 40/50 HP. Chassis. | ||
