| -10- HS{Lord Ernest Hives - Chair}/IHM.Y/WH.9.5.38. Floatox bushes for body mounting. They were satisfactory but allowed the body to shake sideways on the chassis at the rear end. A transverse stay as found necessary on Ph.III has been recommended. Side Steering Tube Ldr.FS.{F. Steele}1315. Special springs supplied by ae/PJR. The special springs were for the purpose of absorbing slight joggles previously experienced. They were effective in this respect and the extra sponge introduced was not objected to. The ball pads made an audible clatter against their stops when cornering. This has been dealt with by eliminating the stops and making the springs come shoc-a-bloc instead by means of closer wound springs and distance pieces. Pedals Ldr.Ph.904. Engine vibration could be felt on the brake and clutch pedal if the feet were rested lightly upon them, but with normal use they appeared reasonably well isolated. There is room for improvement. The accelerator chattered against the on stop on full throttle. This appears to be as much due to direct transmission of frame shocks as to engine movements. A rubber on stop proved a complete cure, and is recommended for production. Spring Suspension Ldr.GR.{George Ratcliffe}1613. Front axle Ldr.DR.1507. Gr.{George Ratcliffe}1488/9 Axle Yokes to Ex.82 and 82.A. for 4° Castor. The steering tightened up at intervals during the mileage. This was due to the pivots picking up in the hardened steel bushes. There is a modification with needle roller bearings for production. Creaks developed from the lower yoke bearings due to insufficient lubrication. The bijur feeds are to be increased from 7/32 to 25/64 for production. It is important that these bearings are well primed with oil on assembly. Cont'd.{John DeLooze - Company Secretary} | ||
