X1265 W/P (Levallois) - Sr/Va. Hs{Lord Ernest Hives - Chair}/Les.17/KW.11.10.35. Chassis GAE-26. Marquis de Bourg de Bozas. Re Sr/Va.7/GM.9.10.35. From the information given I am afraid it is impossible to give any very useful information. The standard initial damper load of 30 lbs. should be quite low enough for the very softest ride. You might find that with a pressure gauge in the governor system you were not getting as low as 1 1/2 lbs./sq.in. pressure at 10 m.p.h. in the soft position of the control. If above this pressure, either lengthening the rod to the unit, or more clearance for the over-riding control spring F.85377 will reduce the minimum pressure. It sounds strange, however, that you should have a customer in France who requires a softer ride than the average English owner. For the softest riding the lowest poundage low rating springs which do not cause complaints of the axles hitting the buffers are the best. If you can let me know any further details with regard to this complaint, such as pitching of the car, steering, and actual harshness over small bumps, we might be able to help you a little. The best solution may be for the owner to try a Phantom III. Hs{Lord Ernest Hives - Chair}/Les.{Ivan A. Leslie} | ||
