| X5350 BY.{R.W. Bailey - Chief Engineer} from DA.{Bernard Day - Chassis Design} c. to BJ. Hs.{Lord Ernest Hives - Chair} DA{Bernard Day - Chassis Design}1/M7.11.28. INDIA 4. REAR AXLE. X.5350 X.2066 X.5420 Herewith we send N.sch.8757 shewing the slight alterations to the rear hub and brake drum which are needed to use the rebuilt wire wheels with the 1.750" offset front axle. At the moment we have kept the brake gear exactly as now, though we think it is possible when we come to design the hypoid axle that it will be desired to revise the brake gear on the lines of 'SS{S. Smith}'. The principle parts affected in this scheme are the hub and central spider for the brake gear and the drum. DA.{Bernard Day - Chassis Design} | ||
