| ( 5 ) FRONT AXLE CONTROLS. LOP GB.1340 The Bearings are not adequate to take the thrust. We have had to adjust them twice. Any slack in these bearings is noticeable in the stability of the steering. Bad juddering of the front Brakes are liable. We have reported upon this slackness developing on every Car we have had. This bearing is important and should have the D/O's attention. EXHAUST SYSTEM. LOP EB.1155 & LOP EB.842. The Cut-out is a continual source of trouble and from our tests at high speeds, does not give an appreciable increase of speed. With the rubber mounted Engine and gearbox, the trouble is amplified. The Exhaust is comparatively quiet. The note from the tail pipe is not at all unpleasant. The stay holding the front Silencer broke close to where it is welded on to the pipe. The rear tail pipe anchorage has worn and rattles. The spherical mounting became dry and squeaked. Bolts holding the front stay of expansion chamber worked loose. PETROL TANK. LOP FB.374. With the increased acceleration and maximum speed, stones have hit the Petrol Tank with more violence, finally puncturing it at the front bottom edge. We have made and fitted a very neat aluminum stone guard from the centre seam to the bottom which protects the part exposed to stones. The anchorage became loose. The two bolts of the stay fastened to top cross member were very loose. The nut of O.S. triangular side stay was found loose. PETROL TANK GUAGE. The Guage used to stick upon filling up, and did not operate until the Car was on the move. We have eased the pinion wheel of the mechanism, making the mechanism less liable to sticking. ROAD SPRINGS. Front. Woodhead's FB.19 - 650 lbs. Rear. FB.22 - 818 lbs. The lubrication of the shackles appears to be satisfactory. We have not had the springs dismantled at this mileage for examination of lubrication. There has not been any indication of spring leaves becoming dry. Anchorage of springs to Axle has remained firm. A general noise comes from underneath, brake rods and connections rattle from pedal to rear of Car. Engine side trays rattle. | ||
