| X7230. By.{R.W. Bailey - Chief Engineer} from Da{Bernard Day - Chassis Design}, c. Hs.{Lord Ernest Hives - Chair} Da{Bernard Day - Chassis Design}/M15.7.30. X7230 P.2. EXHAUST SYSTEM - FRONT EXPANSION BOX. With reference to Hs{Lord Ernest Hives - Chair}/Rn{Mr Robinson}1/MJ11.7.30. we suggest that the flange connecting the down pipe with the expansion chamber should have 8 bolts instead of 4. This brings it more into line with the rear flange which has a great many bolts and should ensure better heat connection and reduced blows. Da.{Bernard Day - Chassis Design} | ||
