| -3- (7) Rear connecting tube. The load on the spring is 300 lbs. It has been proved that this load is not sufficient to keep both pads on the ball ends. Connecting tubes with 500 lbs. springs have now been fitted. (8) At 350 miles there was not sufficient current in the battery to start the engine in the morning. There are three doubtful cells in the battery including the rear cell which usually causes trouble in France. It is suspected that the increased vibration from the hard dampers may be affecting the battery. The battery has been charged up and is now giving satisfaction. (9) At 4000 miles the O.S. front damper became loose on the frame. It is evident that the third stud fixing had not been dead tight. With a complete chassis it is impossible to get a spanner on to the nut correctly. By altering the position of an undershield bolt so that a box spanner can be fitted. (10) General coachwork rattles have increased badly. These are amplified when running with the dampers set hard. This car has a subframe, so a production car may be worse. *-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*- From these trouble there are certain items which still require attention :- (No.5) Shortage of oil in the N.S. Rear dampers. This is the most serious complaint. If the temperature is the cause of the trouble, we shall try a shield between the damper and the silencer combined with a scoop directing cool air on the damper. Beeswax which has a higher melting point than tallow will be tried for the gland. It is feared, however, that beeswax will make the gland too hard to retain oil at any temperature. There are some new type glands being produced to Hs.{Lord Ernest Hives - Chair}1077 which have a flexible bellows connecting the gland to the casing of the damper. This gland should be unaffected by bearing clearance and distortion, and should thus enable a harder material to be used for the gland. (No.6.) Noise from valves. We now have 5 valves and valve chambers exactly similar to those on 104-MY (Sg{Arthur F. Sidgreaves - MD}'s car). These will be run on bumper rigs and also on the damper test rig. | ||
