(2) Item No.2. SHOCK ABSORBERS. Although a lot of work has been done on shock absorbers to eliminate the troubles, we are not in position to say at present, they are trouble proof. With the latest split piston damper, we spring trouble have been practically overcome. A pair of these dampers are now going through a severe test in France on 25-EX. Considerable work by Km. and Brook is gradually deleting the troubles. We trust by these combined efforts to considerably reduce the number of complaints. The front dampers on Phantom II has had a lubrication modification which should delete a number of complaints. Item No.3. SPRINGING. The springing of cars is now considered to be satisfactory. It is divided into two classes. Soft springing for general touring conditions as fitted to the trials cars, and springing suitable for continental work. Shock damper loads are made to suit both cases. Item No.4. FABRIC COUPLING FAILURES. We have not received any recurrent complaint after the fitting of the modified coupling. Item No.5. STEERING. These troubles should gradually become less with more constant results of dampers, and attention paid to cross steering tube contacts on production. Wear of tyres is a cause of steering complaints. Item No.7. EXHAUST TROUBLES. Phantom II manifolds are giving very little trouble. There has been recurrent complaints since the fitting of the silencers with the new type sliding joint. A stay is being fitted to the silencer to overcome the trouble. Phantom I manifolds. The works repair dept. are trying out manifolds made in malleable steel. Exhaust blows are being dealt with by the fitting of the steel lined washers to the manifold joints. | ||
