| X.9420 To BY.{R.W. Bailey - Chief Engineer} & HS.{Lord Ernest Hives - Chair} from DA.{Bernard Day - Chassis Design} S E C R E T. DA{Bernard Day - Chassis Design}1/M5.4.24. E.A.C. FRONT AXLE. X.9420 Thank you for your BY5/14.2.24. We suggest that a useful experiment would be to leave out half the number of bolts, say 11 instead of 21. We are under the impression that this number of bolts should be quite sufficient to hold the carrier side plate without increasing the dia. DA.{Bernard Day - Chassis Design} | ||
