| 442 To By {R.W. Bailey - Chief Engineer} /Ald. {F. Allwood - Experimental Design} from Rm {William Robotham - Chief Engineer} /AFM. {Anthony F. Martindale} c. By. {R.W. Bailey - Chief Engineer} c. Da. {Bernard Day - Chassis Design} Rm {William Robotham - Chief Engineer} /AFM. {Anthony F. Martindale} 7/MH. {M. Huckerby} 5.8.38. B.III FRONT SHOCK DAMPERS. The inter shaft EXS.407 of these dampers is unsatisfactory. The central knurling is the same diameter as the larger bearing, with the result that during assembly the larger rubber gland is damaged. The rubber disintegrates further during running, and causes the valve to seize. Will you please make drawings of a shaft similar to EXS.407, but with a .100" increase of dia. of the larger bearing. A chamfer should lead up to it from the splines. The casing will have to be bored out to take a larger bearing. In other respects the dampers are satisfactory, with the large interference pins, and knurled shafts. Rm {William Robotham - Chief Engineer} /AFM. {Anthony F. Martindale} | ||
