| X4247 Mr D'Aeth. c. EP.{G. Eric Platford - Chief Quality Engineer} c. EPT. c. Hs.{Lord Ernest Hives - Chair} BY1-P25.5.23. 20HP. CHASSIS GEARBOX. CHANGE GEAR MECHANISM. With reference to the question of increasing the strength of the locking spring from 5 1/4 lbs. to 10 lbs. with a plus and minus 1 lb. limit, will you kindly note that I think this should be brought in at once. We think it desirable to change these springs on all chassis on test. This should be done against an A.T.D. number which Mtn. will supply. BY.{R.W. Bailey - Chief Engineer} | ||
