| - 6 - Front road springs. 650 Lbs. Lemoine springs fitted with Befco gaiters. These have been examined and all leaves from outside examination are in good condition. The tyre brackets have become loose, the centrerivet having given way. The lubrication of the springs was very good. The spring clips were tightened up half a turn of the nuts at the beginning of the test. When examined they were still tight. The front and rear anchorage of springs are in good condition. We have not noticed any deterioration in the flexibility of the springs. Front shock dampers. Hydraulic shock dampers arranged in accordance with scheme E.T.1294, also air release scheme to arrangt.Drg. F.74419. These are a considerable improvement in the effect they have upon the riding of the front of car. The sharp dipping of front has entirely disappeared and the hitting of the buffers has been considerably lessened. The rebound is not so effectively cured and we believe a slight more damping would be beneficial. There is a slight oil leak from shaft at O.S.and from top cap at N.S. It has not been necessary to adjust the connecting links. Clutch. The clutch did not stop readily when the car was taken over. It has gradually become worse, and will not stop either cold or hot. We have tried without dismantling by resetting the levers to improve this but with very little improvement. When it has been stopped the gear can be taken out and clutch will remain stationary. The clutch has been smooth in action when engaging and we have not had any signs of clutch slipping. Gearbox. All gearbox joints fitted with vellumoid washer to L.O.T.S.S1570 The gearbox generally is very good, the gears are good and side shaft has remained quiet. The bad oil leaks reported come from top cover of change operating shaft tower, where exhaust cutout lever is attached. The leak comes from the rear of cover and from observations, we believe that a further stud and nut at this end would prevent the leak otherwise position of the existing four studs could be altered so as to distribute a more even pressure on the joint. There is a leak of oil from the housing of operating shaft to servo at pedal side. The oil drips from the end of housing. There is also a leak of oil from housing of speedometer drive. There has been slight leaks of oil from rear housing and side plates. These leaks we have almost cured by tightening up the nuts on plates. The servo side of gearbox appears to be free from oil leaks. Gear change mechanism. The gear change mechanism has functioned O.K. At high speeds the lever chatters sidewards in the quadrant; considerable vibrations are felt on the lever. This is very noticeable if the driver's leg | ||
