| Hs.{Lord Ernest Hives - Chair} from BY.{R.W. Bailey - Chief Engineer} c. Wd.{Mr Wood/Mr Whitehead} c/o EFC. X.3981 COPY. BY6/P20.5.20. X.3981 CHASSIS - REAR SPRINGS. X.2628.b Have you got any information in regard to the value of the present type of rear spring as sample two pairs, namely, no ribs, ground after hardening and with small camber differences, when central bolt is not pulled up. If the above still squeak it might be advisable to try and get further with bedding the ends of the present spring. In any case we should have some scheme to prevent ends "bitingiin" and its subsequent effect as a squeak. BY.{R.W. Bailey - Chief Engineer} [STAMP] EFC MAY 21 1920 RECEIVED! | ||
