| -2- The radiator is raised by putting thicker packing washers E.81619/20/21/22 in the centre mounting. Care must be taken to allow clearance for the starting handle shaft for all position of the radiator. It may be necessary to add a packing E.82714 between the radiator and the bottom water connection in order to increase the clearance for the bottom water connection under the radiator cross member. Removing material from the radiator cross member to increase the radiator movement should only be done when it is necessary to have more movement than can be obtained from raising the radiator. It is impossible to state the required amount of radiator movement as this depends on the behaviour of the complete car. Radiator "jellying" only comes up when the body is fitted. The radiator control rubbers E.80812 in the cups each side of the centre mounting should be altered to a soft grade of rubber, when a customer complains of jellying. (2) If it is noticed that any of the five cars in question is less smooth than the later chassis it will probably be caused from insufficient clearance between the two castings of the front engine feet. We attach two prints showing the possible places of contact. By removing the four bolts holding the one casting to the crankcase, it is possible to ascertain if there is clearance. (3) We are now fitting some improved friction material for the engine to frame dampers, which are in the front of the engine. We are sending you two samples of this material. Its advantage is that it contains no "bonding" compound. In certain cases it was found that the original material became "gummy" and consequently its load was not proportional to the spring pressure.
