Rm{William Robotham - Chief Engineer}/AFM.{Anthony F. Martindale} BENTLEY III BUMPER CHASSIS. The following sections of the above chassis have been dismantled for inspection after completing 50 hours test on 3" cams and 30 hours on the brake torque rig. Front Shock Dampers to LOP.FB.3465. Front Axle to LOP.FB.3091, incorporating PD.129, needle roller lower pivot bearing. Front Shock Dampers. The general condition of all parts, including the pressed knurled fit shafts and levers Ex.S.704/5 is satisfactory. The lower triangle levers FB.3507/8, produced in cast steel, when magnetic tested showed one or two small cracks; these, apparently, are due to faulty castings. A small crack has developed in the web of the off side torque arm FB.2980; the position of this is indicated in the photograph attached. The near side is in good condition. Both torque arms have been produced in cast steel. The spherical torque arm bushes FB.3650 are badly worn internally. Front Axle. The yoke pieces Ex.S.822/3 and axle pivots are in good condition, being free from cracks; also, the alignment on each piece has been checked over and found correct. The off side pivot pin FB.3682 has fractured across the .750 diameter - see photograph attached - the near side pin being in good condition. Front Hubs. The condition of all bearings is satisfactory. continued. | ||
