Fowler Clarke - Electrical Engineer} 4/T15.1.26. Tungsten contact point fitted. The battery ignition has not been quite satisfactory. It was necessary at 7,500 miles to replace the contact points as they had become pitted and was not making good contact. These were taken off and sent to Derby. New standard contacts were fitted. These are in a good condition after 2500 miles. The distributor head has remained clean and free from oil. We reported that dust finds its way in through the wire conduits to top of the coil. Bonnet and fittings. We have nothing to add to our previous report at 7500 miles; the conditions have not materially altered. Engine guards and gearbox undershield. We confirm our report at 7500 miles. Radiator. We have had no trouble with the radiator. It has remained in good condition. The bottom anchorage has remained O.K. and appears to be satisfactory. The anchorage of the radiator to the dashboard is the cause of the bonnet chattering endways and making depressions in dashboard and radiator. This is due to the flexibility of the top portion of the dashboard. Radiator shutter & controls. The controls have worked satisfactorily throughout the test. Slight rattles have developed in shutter and loss of movement in controls due to wear. The bowden wire loop where attached to control on radiator has started to fray. Dashboard & brackets. The top corners of dashboard have chattered away by the continual movement of the scuttle. This has been caused by the flexibility of the scuttle and the subframe anchorage not being of sufficient surface to prevent rolling of the body. Steering column & box. New 'D' type steering with outside pendulum lever and larger diameter worm and nut (.700 lead) to N.S. 2066/5/7 and L.O. P. F.5395. The flange at bottom of steering column failed during the last 200 miles. The bottom lugs of flange have cracked half way through. We presume that the bolts had stretched as the nuts were a quarter of a turn loose xxxxxxxx contd :- | ||
